Deep prosthetic infections are a significant cause of failure after arthroplastic surgery. Superficial wound infections are a risk factor for deep infections. We aimed to quantify the risk of deep infection after superficial wound infections, and analyse the microbiology of organisms grown. We defused Superficial Infection according to the definition used by the Centre for Disease Control, and Deep Infection according to the Swedish Hip Register. We retrospectively analysed the results of 6782 THR and TKRs performed consecutively from 1988–1998. We analysed patient records, radiology and microbiological data. The latter collected prospectively by our infection control team. We identified 81 (1. 2%) superficial wound infections, however we had to exclude 3 due to poor follow-up. Of the 78 patients studied, mean age was 71 (23–89), 50 were female, 28 male, 41 THR, 37 TKR and follow-up was a mean 49 months (12–130). The majority (81%) of organisms grown in the superficial wound infections were gram positive Staphylococci. These organisms were most frequently sensitive to Erythromycin or Flucloxacillin. All the superficial infections were treated with antibiotics, 66% settled with less than 6 weeks therapy. Deep prosthetic infections occurred in 10% of superficial infections in both THR and TKR. In 80% of cases the organism in the superficial infection caused the deep infection. Wound dehiscence, haematoma, post-op pyrexia and patient risk factors had no affect on onset of deep infection. However patients who had a wound discharge with positive microbiology and those patients in whom there was clinical doubt about the diagnosis of deep infection and thus had antibiotic therapy for more than six weeks had increased risk of deep sepsis

Aims. There is evidence that morbidly obese patients have more intra- and postoperative complications and poorer outcomes when undergoing total hip arthroplasty (THA) with the direct anterior approach (DAA). The aim of this study was to determine the efficacy of DAA for THA, and compare the complications and outcomes of morbidly obese patients with nonobese patients. Methods. Morbidly obese patients (n = 86), with BMI ≥ 40 kg/m. 2. who underwent DAA THA at our institution between September 2010 and December 2017, were matched to 172 patients with BMI < 30 kg/m. 2. Data regarding demographics, set-up and operating time, blood loss, radiological assessment, Harris Hip Score (HHS), International Hip Outcome Tool (12-items), reoperation rate, and complications at two years postoperatively were retrospectively analyzed. Results. No significant differences in blood loss, intra- and postoperative complications, or implant position were observed between the two groups. Superficial wound infection rate was higher in the obese group (8.1%) compared to the nonobese group (1.2%) (p = 0.007) and relative risk of reoperation was 2.59 (95% confidence interval 0.68 to 9.91). One periprosthetic joint infection was reported in the obese group. Set-up time in the operating table and mean operating time were higher in morbidly obese patients. Functional outcomes and patient-related outcome measurements were superior in the obese group (mean increase of HHS was 52.19 (SD 5.95) vs 45.1 (SD 4.42); p < 0.001), and mean increase of International Hip Outcome Tool (12-items) was 56.8 (SD 8.88) versus 55.2 (SD 5.85); p = 0.041). Conclusion. Our results suggest that THA in morbidly obese patients can be safely and effectively performed via the DAA by experienced surgeons. Cite this article: Bone Jt Open 2022;3(1):4–11

Aims. Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome. Methods. Between 1998 and 2018, 424 consecutive patients were treated with primary ORPF for proximal humerus fracture. ADROM was offered to symptomatic patients with a healed fracture at six months postoperatively. Patients were followed up retrospectively with demographic data, fracture characteristics, and complications recorded. Active range of motion (aROM), Oxford Shoulder Score (OSS), and EuroQol five-dimension three-level questionnaire (EQ-5D-3L) were recorded preoperatively and postoperatively. Results. A total of 138 patients underwent ADROM; 111 patients were available for long-term follow-up at a mean of 10.9 years (range 1 to 20). Mean age was 50.8 years (18 to 75);79 (57.2%) were female. Mean time from primary ORPF to ADROM was 11.9 months (6 to 19). Five patients developed superficial wound infection; ten developed symptomatic osteonecrosis/post-traumatic arthrosis (ON/PTA); four underwent revision arthrolysis. Median OSS improved from 17 (interquartile range (IQR) 12.0 to 22.0) preoperatively to 40.0 (IQR 31.5 to 48.0) postoperatively, and 39.0 (IQR 31.5 to 46.5) at long-term follow-up (p < 0.001). Median EQ-5D-3L improved from 0.079 (IQR -0.057 to 0.215) to 0.691 (IQR 0.441 to 0.941) postoperatively, and 0.701 (IQR 0.570 to 0.832) at long-term follow-up (p < 0.001). We found that aROM improved in all planes (p < 0.001). Among the variables assessed on multivariable analysis, a manual occupation, worsening Charlson Comorbidity Index and increasing socioeconomic deprivation were most consistently predictive of worse patient-reported outcome scores. Patients who subsequently developed ON/PTA reported significantly worse one-year and late OSS. Conclusion. ADROM in patients with persistent symptomatic stiffness following ORPF can achieve excellent short- and long-term outcomes. More deprived patients, those in a manual occupation, and those with worsening comorbidities have worse outcomes following ADROM. Cite this article: Bone Joint J 2022;104-B(1):157–167

Aims. Varus-valgus constrained (VVC) devices are typically used in revision settings, often with stems to mitigate the risk of aseptic loosening. However, in at least one system, the VVC insert is compatible with the primary posterior-stabilized (PS) femoral component, which may be an option in complex primary situations. We sought to determine the implant survivorship, radiological and clinical outcomes, and complications when this VVC insert was coupled with a PS femur without stems in complex primary total knee arthroplasties (TKAs). Methods. Through our institution’s total joint registry, we identified 113 primary TKAs (103 patients) performed between 2007 and 2017 in which a VVC insert was coupled with a standard cemented PS femur without stems. Mean age was 68 years (SD 10), mean BMI was 32 kg/m. 2. (SD 7), and 59 patients (50%) were male. Mean follow-up was four years (2 to 10). Results. The five-year survivorship free from aseptic loosening was 100%. The five-year survivorship free from any revision was 99%, with the only revision performed for infection. The five-year survivorship free from reoperation was 93%. The most common reoperation was treatment for infection (n = 4; 4%), followed by manipulation under anaesthesia (MUA; n = 2; 2%). Survivorship free from any complication at five years was 90%, with superficial wound infection as the most frequent (n = 4; 4%). At most recent follow-up, two TKAs had non-progressive radiolucent lines about both the tibial and femoral components. Knee Society Scores improved from 53 preoperatively to 88 at latest follow-up (p < 0.001). Conclusion. For complex primary TKA in occasional situations, coupling a VVC insert with a standard PS femur without stems proved reliable and durable at five years. Longer-term follow-up is required before recommending this technique more broadly. Cite this article: Bone Jt Open 2021;2(11):921–925

Aims. Graft infection following anterior cruciate ligament reconstruction (ACLR) may lead to septic arthritis requiring multiple irrigation and debridement procedures, staged revision operations, and prolonged courses of antibiotics. To our knowledge, there are no previous studies reporting on how gentamicin pre-soaking of hamstring grafts influences infection rates following ACLR. We set out to examine this in our study accordingly. Methods. This retrospective study included 2,000 patients (1,156 males and 844 females) who underwent primary ACLR with hamstring autografts between 2007 to 2017. This included 1,063 patients who received pre-soaked saline hamstring grafts for ACLR followed by 937 patients who received pre-soaked gentamicin hamstring grafts for ACLR. All operative procedures were completed by a single surgeon using a standardized surgical technique. Medical notes were reviewed and data relating to the following outcomes recorded: postoperative infection, clinical progress, causative organisms, management received, and outcomes. Results. Superficial wound infection developed in 14 patients (1.31 %) receiving pre-saline soaked hamstring grafts compared to 13 patients (1.38 %) receiving pre-gentamicin soaked hamstring grafts, and this finding was not statistically significant (p = 0.692). All superficial wound infections were treated with oral antibiotics with no further complications. There were no recorded cases of septic arthritis in patients receiving pre-gentamicin soaked grafts compared to nine patients (0.85%) receiving pre-saline soaked grafts, which was statistically significant (p = 0.004). Conclusion. Pre-soaking hamstring autographs in gentamicin does not affect superficial infection rates but does reduce deep intra-articular infection rates compared to pre-soaking hamstring grafts in saline alone. These findings suggest that pre-soaking hamstring autografts in gentamicin provides an effective surgical technique for reducing intra-articular infection rates following ACLR.

Abstract. Background. Multiple devices can stabilise the MTP joint for arthrodesis. The ideal implant should be easy to use, provide reproducible and high quality results, and ideally enable early rehabilitation to enable faster return to function, whilst lessening soft tissue irritation. We prospectively evaluated the combination of the IO-Fix (Extremity Medical, NJ, USA) device which consists of an intra-osseous post and lag screw that offers these features with full bearing of weight after surgery. Methods. 67 feet in 65 patients were treated over 31 months. After excluding patients lost to follow-up, undergoing revision arthrodesis, or concomitant first ray procedures, there were 54 feet in 52 patients available with a minimum 12 month follow-up with clinical and radiographic outcomes. All patients were treated using a similar operative technique with immediate bearing of weight in a rigid soled shoe. Results. The mean MOXFQ score improved from 46.4 (range 18 – 64) before surgery to 30.2 (range 0 – 54) at 6 months after surgery (p=0.02), and 18.4 (range 0 – 36) (p< 0.001) at latest follow-up. Arthrodesis across the MTP joint was achieved in 52 feet (96%), at a mean of 61 days (range 39–201). Non-union was observed in two feet; superficial wound infections in two feet; and metalwork impingement in three feet. Conclusions. In the largest reported series to date, the IO-Fix device achieved a union rate of 96% across the MTP joint when coupled with immediate bearing of weight. Significant improvements were seen in patient reported outcomes with low complication rates

In 2020, the COVID-19 pandemic meant that proceeding with elective surgery was restricted to minimise exposure on the wards. In order to maintain throughput of elective cases, our hospital was forced to convert as many cases as possible to same day procedures rather than overnight admission. In this retrospective analysis we review the cases performed as same day arthroplasty surgeries compared to the same period 12 months previous. We conducted a retrospective analysis of patients undergoing total hip and knee arthroplasties in a three month period between October and December in 2019 and again in 2020, in the middle of the SARS-CoV-2 pandemic. Patient demographics, number of out-patient primary arthroplasty cases, length of stay for admissions, 30-day readmission and complications were collated. In total, 428 patient charts were reviewed for the months of October-December of 2019 (n=195) and 2020 (n=233). Of those, total hip arthroplasties comprised 60% and 58.8% for 2019 and 2020, respectively. Demographic data was comparable with no statistical difference for age, gender contralateral joint replacement or BMI. ASA grade I was more highly prevalent in the 2020 cohort (5.1x increase, n=13 vs n=1). Degenerative disc disease and fibromyalgia were less significantly prevalent in the 2020 cohort. There was a significant increase in same day discharges for non-DAA THAs (2x increase) and TKA (10x increase), with a reciprocal decrease in next day discharges. There were significantly fewer reported superficial wound infections in 2020 (5.6% vs 1.7%) and no significant differences in readmissions or emergency department visits (3.1% vs 3.0%). The SARS-CoV-2 pandemic meant that hospitals and patients were hopeful to minimise the exposure to the wards and to not put strain on the already taxed in-patient beds. With few positives during the Coronavirus crisis, the pandemic was the catalyst to speed up the outpatient arthroplasty program that has resulted in our institution being more efficient and with no increase in readmissions or early complications

Introduction. Cheilectomy is a recommended procedure for the earlier stages of osteoarthritis of the 1. st. metatarsophalangeal joint. Although good improvement in symptoms have been reported in many studies, the long term performance of this procedure is not well understood. It is thought that a significant number of patients go onto have arthrodesis or joint replacement. We report on a large cohort of patients who received this procedure and report on the complications and mid-term outcome. Methods. This is a retrospective study looking at all patients who underwent cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to access patient details and outcome measures recorded include: postoperative wound infection, patient reported improvement in pain and the incidence of further surgical interventions like revision cheilectomy and conversion to arthrodesis and arthroplasty. X-rays were studied using PACS to stage the osteoarthritis (Hattrup and Johnson classification). Results. A total of 240 feet in 220 patients (20 bilateral surgeries) were included in the study, there were 164 Females (75%) and 56 Males (25%), the median age was 55 years (range 22–90 years). Radiological assessment showed 89 Stage 1 arthritis(42%), 105 Stage 2 (50%), 17 Stage 3 (8%) and 9 patients were excluded due to unavailable X-rays. 5 patients (2%) had superficial wound infection. There were 16 further surgeries (7%) performed in this cohort, 12 arthrodesis (5%), 3 revision cheilectomy and 1conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to unavailable data. Conclusion. Cheilectomy appears to produce good improvement in pain with a low complication rate. The rate of conversion to arthrodesis/arthroplasty is lower than in many reported studies

Prospective data on hip fracture from 3686 patients at a United Kingdom teaching hospital were analysed to investigate the risk factors, financial costs and outcomes associated with deep or superficial wound infections after hip fracture surgery. In 1.2% (41) of patients a deep wound infection developed, and 1.1% (39) had a superficial wound infection. A total of 57 of 80 infections (71.3%) were due to Staphylococcus aureus and 39 (48.8%) were due to MRSA. No statistically significant pre-operative risk factors were detected. Length of stay, cost of treatment and pre-discharge mortality all significantly increased with deep wound infection. The one-year mortality was 30%, and this increased to 50% in those who developed an infection (p < 0.001). A deep infection resulted in doubled operative costs, tripled investigation costs and quadrupled ward costs. MRSA infection increased costs, length of stay, and pre-discharge mortality compared with non-MRSA infection

Tendoscopy in the treatment of peroneal tendon disorders is becoming an increasingly safe, reliable, and reproducible technique. Peroneal tendoscopy can be used as both an isolated procedure and as an adjacent procedure with other surgical techniques. The aim of our study was to review all peroneal tendoscopy that was undertaken at the AOC, by the senior authors (IGW, SH), and to determine the safety and efficacy of this surgical technique. Methods. From 2000 to 2017 a manual and electronic database search was undertaken of all procedures by the senior authors. Peroneal tendoscopy cases were identified and then prospectively analysed. Results. 51 patients (23 male, 28 female) were identified from 2004–2017 using a manual and electronic database search. The mean age at time of surgery was 41.5 years (range 16–83) with a mean follow-up time post operatively of 11.8 months (range 9–64 months). The main indications for surgery were lateral and/or postero-lateral ankle pain and lateral ankle swelling. The majority of cases showed unstable peroneal tendon tears that were debrided safely using tendoscopy. Of the 51 patients, 23 required an adjacent foot and ankle operation at the same time, 5 open and 17 arthroscopic (12 ankle, 5 subtalar). Open procedures included 2 first ray osteotomies, 2 open debridements of accessory tissue, one PL to PB transfer. One patient also had an endoscopic FHL transfer. Complication rates to date have been low: 2 superficial wound infections (4%) and one repeat tendoscopy for ongoing pain. A small proportion of patients with ongoing pain were treated with USS guided steroid injections with good results. Conclusion. Our series of peroneal tendoscopy has a low complication rate with high patient satisfaction at discharge. Results of tendoscopic treatment are similar to open techniques, however its advantages make tendoscopic procedures an excellent method to treat peroneal tendon disorders

Cheilectomy is a recommended procedure for early stage osteoarthritis of the 1st metatarsophalangeal joint. Although improvement in symptoms has been reported in many studies, long term performance is not well understood. It is thought that significant numbers of patients require subsequent arthrodesis or arthroplasty. We report on a large cohort of patients receiving this procedure and on complications, and mid-term outcome. This is a retrospective study looking at all patients undergoing cheilectomy for hallux rigidus between November 2007 and August 2018. Departmental database was used to record outcome measures including: postoperative wound infection, patient reported improvement in pain and incidence of further surgical interventions like revision cheilectomy, conversion to arthrodesis and arthroplasty. Osteoarthritis was staged radiographically using PACS (Hattrup and Johnson classification). A total of 240 feet in 220 patients (20 bilateral surgeries) were included with 164 females (75%) and 56 males (25%), the median age being 55 years (range 22–90 years). Radiological assessment showed 89 stage 1 arthritis (42%), 105 stage 2 (50%), 17 stage 3 (8%) and 9 patients were excluded due to unavailable radiographs. 5 patients (2%) had superficial wound infections. There were 16 further surgeries (7%); 12 arthrodesis (5%), 3 revision cheilectomy and 1 conversion to arthroplasty. 157 patients were found to be pain-free at the latest post-operative visit (77%), 48 reported minimal pain (23%), 15 patients were excluded due to incomplete data. Cheilectomy appears to effectively reduce pain with low complication rates. Rates of conversion to arthrodesis/arthroplasty are lower than in many reported studies

Constrained acetabular inserts provide a solution for both complex primary and revision hip arthroplasty, but there have been ongoing concerns for high risk of failure and their longevity. The Stryker® Trident acetabular insert is pre-assembled with its constrained ring. We believe this to be the largest series of constrained acetabular inserts with a minimum of 5 year follow-up. We retrospectively reviewed all Stryker® Trident ‘All-Poly’ constrained acetabular inserts cemented into bone in our unit between 2008 and 2016. We collated demographic details and reviewed all patients’ radiographs and clinical notes. Indications for surgery, latest Oxford Hip Scores (OHS) and clinical and radiographic complications were identified. 117 consecutive Stryker® Trident ‘All-Poly’ constrained inserts were cemented into bone in 115 patients during the study period with a mean age of 80 (47–97). Most common indications for surgery were recurrent dislocation (47), complex primary arthroplasty (23), revision arthroplasty (19) and failed hemiarthroplasty (12). 41 patients required revision of the acetabular component only. Follow-up was a minimum of 5 years (mean 8.6, range 5–13). There were three 30-day mortalities and six 1-year mortalities. The mean latest OHS was 37 (24–45). Four cups failed in three patients, one at the cement-bone interface, two at the cement-prosthesis interface and one at the bipolar interface. These were treated conservatively in three patient and with excision arthroplasty in one patient. There were four peri-prosthetic fractures, one Vancouver C distal femur fracture treated conservatively and three Vancouver B1 fractures, two treated conservatively and one treated with open reduction internal fixation. There was breakage of one constrained ring with no adverse effects and one superficial wound infection requiring oral antibiotics only. This series demonstrated that despite the elderly and complex nature of these patients’ clinical situations, constrained acetabular inserts offer a useful and pragmatic solution, with relatively low complications, including in our series a cup failure rate of 3% and peri-prosthetic fracture rate of 3%

In order to define the predisposing factors and outcome of infected arthroplasty of the knee, a retrospective analysis of a consecutive series of 471 knee arthroplasties was performed. There were 23 cases of superficial wound infection and 25 of deep infection. Superficial wound infection alone resulted in a painfree gait, with little limitation of movement. Rheumatoid arthritis, the use of constrained prostheses and the presence of a superficial wound infection, all predisposed to deep infection. Deep infection was eradicated by long-term antibiotics in only two patients in whom skin cover was successfully provided by a gastrocnemius musculocutaneous flap. Excision of a sinus track, wound debridement and exchange arthroplasty were universally unsuccessful. Arthrodesis, however, in 11 out of 12 cases, provided the painfree gait these patients desire

The primary aim was to determine the rate of complications and re-intervention rate in a consecutive series of operatively managed distal radius fractures. Data was retrospectively collected on 304 adult distal radius fractures treated at our institution in a year. Acute unstable displaced distal radius fractures surgically managed within 28 days of injury were included. Demographic and injury data, as well as details of complications and their subsequent management were recorded. There were 304 fractures in 297 patients. The mean age was 57yrs and 74% were female. Most patients were managed with open reduction and internal fixation (ORIF) (n=278, 91%), with 6% (n=17) managed with manipulation and Kirschner wires and 3% (n=9) with bridging external fixation. Twenty-seven percent (n=81) encountered a post-operative complication. Complex regional pain syndrome was most common (5%, n=14), followed by loss of reduction (4%). Ten patients (3%) had a superficial wound infection managed with oral antibiotics. Deep infection occurred in one patient. Fourteen percent (n=42) required re-operation. The most common indication was removal of metalwork (n=27), followed by carpal tunnel decompression (n=4) and revision ORIF (n=4). Increasing age (p=0.02), male gender (p=0.02) and high energy mechanism of injury (p<0.001) were associated with developing a complication. High energy mechanism was the only factor associated with re-operation (p<0.001). This study has documented the complication and re-intervention rates following distal radius fracture fixation. Given the increased risk of complications and the positive outcomes reported in the literature, non-operative management of displaced fractures should be considered in older patients

Residual Legg-Calve-Perthes (LCP) deformities represent one of the most challenging disorders in hip reconstructive surgery. We assessed mid-term PRO. M. s, radiographic correction, complications and survivorship of combined surgical dislocation (SD) and periacetabular osteotomy (PAO) for the treatment of complex LCP deformities. A longitudinal cohort study was performed on 31 hips with complex LCP deformities undergoing combined SD/PAO. Treatment included femoral head reshaping, trochanteric advancement and relative neck lengthening, management of intra-articular lesions and PAO. Twenty-seven (87.1%) had minimum 5-year follow up. Average age was 19.8 years with 56% female and 44% having previous surgery. At a mean 8.4 years, 85% (23/27) of the hips remain preserved (no conversion to THA). The survivorship estimates at 5 and 10 years were 93% and 85%, respectively. The median and interquartile range for mHHS increased from 64 [55–67] to 92 [70–97] (p<0.001), the WOMAC-pain improved from 60 [45–75] to 86 [75–100] (p= 0.001). An additional 19% (n=5) reported symptoms (mHHS <70) at final follow-up. UCLA activity score increased from a median of 8 [6–10] to 9 [7–10] (p=0.207). Structural correction included average improvements of acetabular inclination 15.3. o. ± 7.6, LCEA 20.7° ± 10.8, ACEA 23.4° ± 16.3, and trochanteric height 18 mm ± 10 mm (all, p<0.001). Complications occurred in two (7%) patients including one deep and one superficial wound infection. At intermediate follow-up of combined SD/PAO for complex LCP deformities, 85% of hips are preserved. This procedure provides reliable deformity correction, major pain relief, improved function and acceptable complication/failure rates

Aims. In 2020, the COVID-19 pandemic meant that proceeding with elective surgery was restricted to minimize exposure on wards. In order to maintain throughput of elective cases, our hospital (St Michaels Hospital, Toronto, Canada) was forced to convert as many cases as possible to same-day procedures rather than overnight admission. In this retrospective analysis, we review the cases performed as same-day arthroplasty surgeries compared to the same period in the previous 12 months. Methods. We conducted a retrospective analysis of patients undergoing total hip and knee arthroplasties over a three-month period between October and December in 2019, and again in 2020, in the middle of the COVID-19 pandemic. Patient demographics, number of outpatient primary arthroplasty cases, length of stay for admissions, 30-day readmission, and complications were collated. Results. In total, 428 patient charts were reviewed for October to December of 2019 (n = 195) and 2020 (n = 233). Of those, total hip arthroplasties (THAs) comprised 60% and 58.8% for 2019 and 2020, respectively. Demographic data was comparable with no statistical difference for age, sex, contralateral joint arthroplasty, or BMI. American Society of Anesthesiologists grade I was more highly prevalent in the 2020 cohort (5.1-times increase; n = 13 vs n = 1). Degenerative disc disease and fibromyalgia were less significantly prevalent in the 2020 cohort. There was a significant increase in same day discharges for non-direct anterior approach THAs (two-times increase) and total knee arthroplasty (ten-times increase), with a reciprocal decrease in next day discharges. There were significantly fewer reported superficial wound infections in 2020 (5.6% vs 1.7%) and no significant differences in readmissions or emergency department visits (3.1% vs 3.0%). Conclusion. The COVID-19 pandemic meant that hospitals and patients were hopeful to minimize the exposure to the wards, and minimize strain on the already taxed inpatient beds. With few positives during the COVID-19 crisis, the pandemic was the catalyst to speed up the outpatient arthroplasty programme that has resulted in our institution being more efficient, and with no increase in readmissions or early complications.

Introduction: Hip fractures affects more than 65,000 people in the UK each year and this number is increasing. The standard treatment is insertion of either a dynamic hip screw or hemiarthroplasty depending on fracture configuration. Because of their advanced age, associated co-morbid factors as well as having had an implant inserted, hip fracture patients are at increased risk of developing post-operative wound infections. The infection rate for hip fracture surgery is quoted at 0.6 – 3.6%. 1. . Methods: We carried out a retrospective study of the readmission rate due to wound infection following treatment of their fractured neck of femur. 20 patients (16 females and 4 males) were identified over a 24 month period out of a total 1786 femoral neck fractures treated (1.1%). Results: 11 patients re-admitted with a wound infection had had a hemiarthroplasty fixation, 9 following insertion of a DHS. 7 patients (0.4%) had a superficial wound infection (3 hemi, 4 DHS) and 13 (0.7%) a deep wound infection (8 hemi, 5 DHS). Treatment for the superficial wound infections included 6 patients requiring IV antibiotics and 1 requiring washout and resuturing of the wound. Treatment of deep wound infections included 6 who had a Girdlestone procedure, 2 had wound washout, debridement and 2 who had removal of DHS. All received IV antibiotics. 2 patients were deemed unfit for surgery and received IV antibiotics only. 3 patients with a deep wound infection (23%) died (2 deemed unfit for surgery, and 1 Girdlestone) during their admission. 85% of the readmissions had an ASA score of three or over. We looked at the length of operation time and found that 15 took less than 45 minutes, 4 took between 45 and 60 minutes and one took over 60 minutes. Three of the operations which took over 45 minutes developed deep infections. Conclusion: Fractured neck of femur accounts for a large proportion of fracture admissions. Accepted methods of treatment carry significant infection rates. Superficial wound infections can in the majority be treated with IV antibiotics. Deep wound infections carry a significant mortality rate. Operating time should be within 45 minutes where possible to reduce the risk of deep infection. Post-operative wound infections are associated with an ASA grade of 3 or greater

Aims. Open tibial fractures are limb-threatening injuries. While limb loss is rare in children, deep infection and nonunion rates of up to 15% and 8% are reported, respectively. We manage these injuries in a similar manner to those in adults, with a combined orthoplastic approach, often involving the use of vascularised free flaps. We report the orthopaedic and plastic surgical outcomes of a consecutive series of patients over a five-year period, which includes the largest cohort of free flaps for trauma in children to date. Methods. Data were extracted from medical records and databases for patients with an open tibial fracture aged < 16 years who presented between 1 May 2014 and 30 April 2019. Patients who were transferred from elsewhere were excluded, yielding 44 open fractures in 43 patients, with a minimum follow-up of one year. Management was reviewed from the time of injury to discharge. Primary outcome measures were the rate of deep infection, time to union, and the Modified Enneking score. Results. The mean age of the patients was 9.9 years (2.8 to 15.8), and 28 were male (64%). A total of 30 fractures (68%) involved a motor vehicle collision, and 34 (77%) were classified as Gustilo Anderson (GA) grade 3B. There were 17 (50%) GA grade 3B fractures, which were treated with a definitive hexapod fixator, and 33 fractures (75%) were treated with a free flap, of which 30 (91%) were scapular/parascapular or anterolateral thigh (ALT) flaps. All fractures united at a median of 12.3 weeks (interquartile range (IQR) 9.6 to 18.1), with increasing age being significantly associated with a longer time to union (p = 0.005). There were no deep infections, one superficial wound infection, and the use of 20 fixators (20%) was associated with a pin site infection. The median Enneking score was 90% (IQR 87.5% to 95%). Three patients had a bony complication requiring further surgery. There were no flap failures, and eight patients underwent further plastic surgery. Conclusion. The timely and comprehensive orthoplastic care of open tibial fractures in this series of patiemts aged < 16 years resulted in 100% union and 0% deep infection, with excellent patient-reported functional outcomes.

Purpose. Recently many authors have questioned the role of tourniquets in primary knee arthroplasty (TKA). Meanwhile, whether the use of an intra-articular wound drainage is an advance over the lack of a drain in TKA is controversial in the literature. This study aimed to investigate the efficacy and safety of drainage or not in TKA without a tourniquet. Methods. Eighty participants who underwent primary unilateral TKA were prospectively enrolled and were randomized to one of two techniques during surgery without a tourniquet: drainage (Group A) or non-drainage (Group B). Blood loss was monitored perioperatively. The operating time, allogeneic blood transfusion rate, thigh pain, knee pain, limb swelling, clinical outcome as measured by the hospital for special surgery (HSS) score, the ability to straight-leg raise, visual analog scale (VAS) in pain, length of stay and knee active range of motion (ROM) were also recorded. The digital radiographs taken at 6 months postoperatively were assessed for cement mantle thickness and radiolucency using the Knee Society radiographic zones. Results. The mean Haemoglobin levels on day one and three postoperative were significantly higher in Group B (112.1±10.6 mg/dL, 99.5±9.6 mg/dL) than in Group A (106.1±12.4 mg/dL, 92.7±13.1 mg/dL) (P=0.026, P=0.011). Blood or blood product transfusion was necessary for thirteen patients in Group A (33.3%) whereas five patients of Group B (13.1%) were in need of blood products, the difference was significant (P=0.036). The total blood loss in Group A was significant more than Group B (597.7 ± 331.6ml vs. 496.1 ± 260.8ml, P=0.012). Among the patients in Group B, haemarthrosis developed in 3 knees (7.9%, P=0.23). Calf circumference measurements of both groups showed a significant difference at postoperative day one (3.2% vs. 5.6%, P = 0.012) as well as day two (4.9% vs. 7.1%, P = 0.07). A superficial wound infection was detected within 3 months after surgery in 3 knees (7.6%) in Group A, whereas no superficial wound infection was observed in Group B, the difference between groups did not reached statistical significance (P=0.248). The difference in VAS score of knee active pain between groups on postoperative day three, five and three weeks were statistically significant (P=0.012, P=0.003, P=0.008). There were no differences in terms of surgical time, thigh/knee rest pain scores, discharge/post-op three weeks HSS score, range of motion, ambulation time, straight-leg raising rate, knee/ thigh circumference, length of stay, cement mantle thickness, or the presence of radiolucency. Conclusions. Drainage does not exhibit substantial advantages in promoting post-operative rehabilitation after uncomplicated TKA, compared with non-drainage. On the other hand, it might increase blood loss and wound complication. Therefore, we believe that it is safe and beneficial for our patients to routinely perform uncomplicated TKA without a postoperative drain if the procedure is done without a tourniquet. On condition that prolonged operation time, multiple extra bone cutting, operative outside joint capsule, we still recommend placing a drainage tube

Introduction. Simultaneous correction of knee varus malalignment with medial open wedge high tibial osteotomy (MOWHTO) combined with anterior cruciate ligament (ACL) surgery aims to address symptomatic unicompartmental osteoarthritis in addition to restore knee stability in order to improve outcomes. The aim of this study is to present at least 5 years results of 32 patients who underwent simultaneous knee realignment osteotomy with ACL surgery. Methods. Patients with symptomatic instability due to chronic ACL deficiency or failed previous ACL surgery together with a varus malalignment of ≥6°, previous medial meniscectomy and symptomatic medial compartment pain who were treated with MOWHTO combined with ACL surgery were enrolled. ACL surgery was performed with the anatomical single bundle all-inside technique using TightRope. ®. RT (Arthrex, Naples, FL, USA) and MOWHTO using TomoFix. ®. medial high tibia plate (DePuy Synthes, Raynham, MA, USA) in all cases. Patients were evaluated preoperatively and at 6 months, 12 months and annually postoperatively using the Knee Injury and Osteoarthritis Outcome Score (KOOS), Oxford Knee Score (OKS) and Euroqol's Visual Analogue Score (VAS) for pain. Results. 32 patients (22 men and 10 women) with a mean age of 41.2 years and mean BMI of 28.6 kg/m. 2. , underwent the combined procedures. Tibiofemoral neutral re-alignment was achieved in all patients with HTO. Complete subjective and objective scores have been obtained in 84.4% of patients with at least 5 years of follow-up (mean 8.7 years). An improvement in total KOOS of 27.1 points (p<0.003), OKS of 15.1 (p<0.003) and VAS for pain of 24.7 points (p<0.001) were detected. No ACL reconstruction failure was noted. Complications consisted of one superficial wound infection and one delayed union. Plate removal was needed in 20 (62.5%) patients due to pes anserinus pain. Conclusions. Simultaneous restoration of coronal knee axis by applying HTO and stability by ACL reconstruction/revision were reported to offer excellent improvement in early outcomes in patients with ACL rupture and symptomatic unicompartmental osteoarthritis. The combined procedure requires careful pre-operative planning and is therefore technically challenging. However, by restoring the neutral axis and providing stability, it represents a good joint preserving alternative to arthroplasty for active middle-aged patients

Blood management protocols attempt to reduce blood loss by strategies including autologous blood donation, red cell salvage, normovolaemic haemodilution and haemostatic agents such as tranexamic acid (TXA). TXA usage in particular has become increasingly commonplace with numerous studies demonstrating a significant reduction in peri-operative blood loss and proportion of patients requiring transfusion, without increasing the risk of venous thromboembolism. Tourniquet usage has now become ubiquitous in TKA operations with reported benefits of improved visualization, shorter operative time and decreased intra-operative bleeding. However, its use is not without considerable complications including wounding dehiscence, increased venous thromboembolism, superficial wound infection and skin blistering. It is therefore imperative that we review tourniquet usage in light of ever evolving blood management strategies. The aim of this study was to evaluate the effect of stopping tourniquet usage in primary TKRs, performed by an experienced surgeon, in light of new blood reduction measures, such as a TXA. A retrospective analysis identified a total of 31 patients who underwent primary TKR without the use of a tourniquet from January 2018 to March 2019. This was compared to an earlier group of patients from the same surgeon undergoing TKR with the use of a tourniquet; dating from July 2016 to November 2017. All surgeries were performed within the same hospital (CXH). Peri-operative factors and outcome measures were collected for analysis. There was no significant difference in post-operative haemoglobin drop (Tourniquet, 23.1 g/L; No Tourniquet, 24.4 g/: p=0.604) and fall in haematocrit (Tourniquet, 0.082; No Tourniquet, 0.087: p=0.604). Allogenic blood transfusion rates were the same in both groups at 12.9% (2 patients) and blood loss was not found to be significantly different (Tourniquet, 1067ml; No tourniquet, 1058mls). No significant difference was found in operative time (Tourniquet, 103 minutes; No Tourniquet, 111.7 minutes: p=0.152) or length of stay (Tourniquet, 5.5 days; No Tourniquet, 5.2 days: p=0.516). Tranexamic acid usage was not found to be significant (p=1.000). ROM of motion and analgesia requirement was significantly better in the no tourniquet group on one post-operative day out of five analysed (p=0.025, p=00.011). No post-operative thromboembolic events were reported in either group. There was no significant difference in readmission rates (p=0.492) or complications (p=0.238). The increase in minor complications and potential increased VTE risk with tourniquet usage must be balanced against an improved visual field and reduced blood loss in TKR patients. Our study found no difference in post-operative blood loss and transfusion rates between tourniquet and no tourniquet groups. With ever evolving and improving blood loss management strategies, including the use of TXA, the application of tourniquet may not be needed. Further prospective RCTs are needed to assess the impact of tourniquet usage in light of this

Intra-articular distal humeral fractures in the elderly are difficult to treat. There is evidence in the literature to support the use of both Open Reduction and Internal Fixation (ORIF) and Total Elbow Arthroplasty (TEA) as primary procedures, although we have been unable to find any direct comparisons of outcome. This study reports the results of ORIF in 12 elderly patients with distal humeral fractures and compares the outcome with 12 matched patients who had undergone TEA. All procedures were performed by two experienced Consultant Surgeons. The Coonrad-Morrey TEA was used in all cases of TEA and a double-plating technique was used in all ORIFs. Both groups of patients were similar with respect to fracture configuration, age, sex, co-morbidity and hand dominance. The mean follow-up in both groups of patients was over 30 months. At final review, patients who had had a TEA had a mean Mayo score of 91 and a range of flexion/extension of 90 degrees. There was 1 superficial wound infection that resolved with antibiotics, 1 temporary radial nerve palsy, and 1 case of heterotrophic ossification The ORIF group had a mean Mayo score of 89 (p> 0.05) and a range of flexion/extension of 112 degrees (P=0.03). There was 1 case of heterotrophic ossification, 2 cases of ulnar nerve compression that needed decompression and 1 superficial wound infection that resolved with antibiotics. All the fractures united. This study indicates that both treatment modalities can lead to excellent results. ORIF has the advantage of preserving the joint and once union has occurred has a low risk of long term complications

Background: Intra-articular distal humeral fractures in the elderly are difficult to treat.

Our study sought to establish the necessity of prolonged pre-operative antibiotic prophylaxis in patients presenting with zone II and zone V acute flexor tendon injuries (FTI). We hypothesized that a single dose of prophylactic antibiotic was adequate in prevention of post-operative wound infection in acute zone II and V FTI. This was a prospective study of 116 patients who presented with zone II and zone V acute FTI. The study included patients who were 18 years and older. Those with macroscopic contamination, immunocompromised, open fractures, bite injuries, and crush injuries were excluded. Patients were randomised into a group receiving a single dose of prophylactic antibiotic and another group receiving a continuous 8 hourly antibiotic doses until the day of surgery. Each group was subdivided into occupational and non-occupational injuries. Their post-operative wound outcomes were documented 10 – 14 days after surgery. The wound outcome was reported as no infection, superficial infection (treated with wound dressings), and deep infection (requiring surgical debridement). There was 0.9% rate of deep post-operative wound infections, which was a single zone V acute FTI case in a single dose prophylactic antibiotic group. There was a 7.8% superficial post-operative wound infection rate, which was mainly zone II acute FTI in both antibiotic groups. There was a strong association between zone II acute FTI and post-operative wound infection (p < 0.05). There was no association between (antibiotic dosage or place of injury) with post-operative wound infection (p > 0.05). There is no benefit in prescribing prolonged pre-operative antibiotic in patients with acute, simple lacerations to zone II and zone V FTI if there is no macroscopic wound contamination

Aims. The aim of this study was to report a retrospective, consecutive series of patients with adolescent idiopathic scoliosis (AIS) who were treated with posterior minimally invasive surgery (MIS) with a mean follow-up of two years (. sd. 1.4; 0.9 to 0 3.7). Our objectives were to measure the correction of the deformity and record the peri-operative morbidity. Special attention was paid to the operating time (ORT), estimated blood loss (EBL), length of stay (LOS) and further complications. Patients and Methods. We prospectively collected the data of 70 consecutive patients with AIS treated with MIS using three incisions and a muscle-splitting approach by a single surgeon between June 2013 and February 2016 and these were retrospectively reviewed. There were eight male and 62 female patients with a mean age of 15 years (. sd. 4.5 ) with a mean body mass index of 19.8 kg/m. 2. (. sd. 5.4). The curves were classified according to Lenke; 40 curves were type 1, 15 were type 2, three were type 3, two were type 4, eight were type 5 and two were type 6. Results. The mean primary Cobb angle was corrected from 58.9° (. sd. 12.6°) pre-operatively to 17.7° (. sd.  10.2°) post-operatively with a mean correction of 69% (. sd. 20%, p < 0.001). The mean kyphosis at T5 to T12 increased from 24.2° (. sd. 12.2°) pre-operatively to 30.1° (. sd. 9.6°, p < 0.001) post-operatively. Peri-operative (30 days) complications occurred in three patients(4.2%): one subcutaneous haematoma, one deep venous thrombosis and one pulmonary complication. Five additional complications occurred in five patients (7.1%): one superficial wound infection, one suture granuloma and three delayed deep surgical site infections. The mean ORT was 337.1 mins (. sd. 121.3); the mean EBL was 345.7 ml (. sd. 175.1) and the mean LOS was 4.6 days (. sd. 0.8). Conclusion. The use of MIS for patients with AIS results in a significant correction of spinal deformity in both the frontal and sagittal planes, with a low EBL and a short LOS. The rate of peri-operative complications compares well with that following a routine open technique. The longer term safety and benefit of MIS in these patients needs to be evaluated with further follow-up of a larger cohort of patients. Cite this article: Bone Joint J 2017;99-B:1651–7

Background: Patients undergoing total knee arthroplasty (TKA) frequently require allogenic blood transfusion. The incidence of blood transfusion varies between 1.4 and 24.5% in the published literature. Purpose of the study: In order to determine the incidence of allogenic blood transfusion in patients undergoing primary TKA at our centre, we performed retrospective analysis of prospectively collected data for all patients who underwent TKA between 1 April 2006 and 31 March 2008. Material and Methods: 1488 eligible patients were categorized into two groups: those who underwent TKA in year 2006 (group I, n= 647) and in year 2007 (group II, n = 841), respectively. Patients with haematological diseases, coagulation disorders or with a known malignancy or infection were excluded. Data were collected for haemoglobin levels (pre-operative, postoperative and predischarge), duration of operation, ASA grade, number of transfusions, use of tranexamic acid and suction drains with relevant clinical data including postoperative medical and surgical complications. Allogenic blood transfusions were administered according to hospital policy. The transfusion threshold was haemoglobin of 8g/dl or less or a symptomatic patient. Results: The two groups were similar with respect to age, gender, ASA, BMI, duration of operation, pre and post-op haemoglobin and tranexamic acid usage. A significantly greater proportion of patients in group I required allogenic blood transfusion when compared to group II. (4.2% vs. 1.2%, group I vs. group II, p < 0.001; respectively). In group I, the usage of suction drain was significantly greater when compared to group II (48% vs. 20%, group I vs. group II, p = 0.27 respectively). The medical complications in group I, included superficial wound infections (two patients), myocardial ischemia (one patient) and reversible acute renal failure (one patient), while in group II, one patient developed a superficial wound infection, which was treated with oral antibiotics. Conclusion: A low rate of allogenic blood transfusion can be achieved by using tranexamic acid and minimising insertion of suction drains. To the best of our knowledge, we report the lowest rate of allogenic blood transfusion for primary TKA. Our data have important implications in the management of patients undergoing TKA

Between 1993 and 2008, 41 patients underwent total coccygectomy for coccydynia which had failed to respond to six months of conservative management. Of these, 40 patients were available for clinical review and 39 completed a questionnaire giving their evaluation of the effect of the operation. Excellent or good results were obtained in 33 of the 41 patients, comprising 18 of the 21 patients with coccydynia due to trauma, five of the eight patients with symptoms following childbirth and ten of 12 idiopathic onset. In eight patients the results were moderate or poor, although none described worse pain after the operation. The only post-operative complication was superficial wound infection which occurred in five patients and which settled fully with antibiotic treatment. One patient required re-operation for excision of the distal cornua of the sacrum. Total coccygectomy offered satisfactory relief of pain in the majority of patients regardless of the cause of their symptoms

We report our experience of treating 17 patients with benign lesions of the proximal femur with non-vascularised, autologous fibular strut grafts, without osteosynthesis. The mean age of the patients at presentation was 16.5 years (5 to 33) and they were followed up for a mean of 2.9 years (0.4 to 19.5). Histological diagnoses included simple bone cyst, fibrous dysplasia, aneurysmal bone cysts and giant cell tumour. Local recurrence occurred in two patients (11.7%) and superficial wound infection, chronic hip pain and deep venous thrombosis occurred in three. Pathological fracture did not occur in any patient following the procedure. We conclude that non-vascularised fibular strut grafts are a safe and satisfactory method of treating benign lesions of the proximal femur

The purpose of this study was to determine the complications after Bernese periacetabular osteomy (PAO) performed by one experienced surgeon using a minimally invasive modified Smith-Petersen approach. Between May 2012 and December 2015, 224 periacetabular osteotomies (PAO) in 201 patients were performed. The perioperative complications were retrospectively reviewed after reviewing clinical notes and radiographs. The mean age was 28.8 years with 179 females and 22 males. The most common diagnosis was acetabular dysplasia with some cases of retroversion. The average lateral centre edge (LCE) angle was 16.5°(−18–45) and mean acetabular index (AI) 16.79° (−3–50). Postoperatively the mean LCE angle was 33.1°(20–51.3) and mean AI 3.0°. (−13.5–16.6). There were no deep infections, no major nerve or vascular injuries and only one allogenic blood transfusion. Nine superficial wound infections required oral antibiotics and two wounds needed a surgical debridement. There was one pulmonary embolus and one deep vein thrombosis. Nine (4%) cases underwent a subsequent hip arthroscopy and three (1.3%) PAO's were converted to a total hip arthroplasty after a mean follow-up of 22 months (3–50). Lateral femoral cutaneous nerve dysaesthesia was noted in 64 (28.6%) PAO's. In 55 (24.5%) an iliopsoas injection of local anaesthetic and steroid for persistent iliopsoas irritation during the recovery phase was given. The minimally invasive modified Smith-Petersen approach is suitable to perform a Bernese periacetabular osteotomy with a low perioperative complication rate. Persistent pain related to iliopsoas is a not uncommon finding and perhaps under-reported in the literature

To identify the incidence of sequential slip of the unaffected hips in patients presenting with unilateral SCFE managed with prophylactic fixation or observation. A retrospective review of all unilateral SCFE treated during 1998 to 2012 was undertaken. The study compares the incidence of sequential slip of the initially unaffected hip in patients managed with prophylactic fixation or observation. The study also reports the incidence avascular necrosis, chondrolysis, and metal-work related problem in this group of patients. All patients included in this current work have at least 12 months of follow-up from the index slip. A total of 44 cases had prophylactic fixation of the unaffected hip (mean age 12.6 years,) and 36 patients managed with regular observation (mean age 13.4 years). Sequential slip of the unaffected hip was noted in a total of 10 patients (28 %) managed with regular observation and only in 1 patient (2%) managed with prophylactic fixation. A Fishers exact test showed significantly high incidence of sequential slip in unaffected hips when managed by regular observation (p-value-0.002). There is no evidence of avascular necrosis or chondrolysis in the unaffected hip in both groups, 3 patients had metalwork related problem and one had superficial wound infection in prophylactic fixation group. Simultaneous prophylactic fixation of the unaffected hips significantly reduces the incidence of sequential slip. This is a relatively safe procedure and should be advocated in all cases of unilateral SCFE to avoid potential complications and preserve function of the unaffected hip

Methods. A retrospective review of 80 patients with unilateral slipped capital femoral epiphysis from 1998–2012 was undertaken to determine the outcome of the unaffected hip. All patients were treated with either prophylactic single Richards screw fixation or observation of the uninvolved hip and were followed up for at least 12 months. The unaffected hip of 44 patients (mean age 12.6 years, range 9–17) had simultaneous prophylactic fixation and 36 patients (mean age 13.4 years, range 9–17.4) were managed with observation. Results. Sequential slip of the unaffected hip was noted in 10 patients (28 per cent) in the observation group and only in 1 patient (2 per cent) in the group managed with prophylactic fixation. A Fisher's exact test showed significantly high incidence of sequential slip in unaffected hips when managed with regular observation (p-value 0.002). Only 3 cases had symptomatic hardware on the unaffected side after prophylactic fixation with one requiring revision of the metal work; one had superficial wound infection treated with antibiotics. No cases had AVN or chondrolysis. Conclusion. Simultaneous prophylactic fixation of the unaffected hip significantly reduces the incidence of sequential slip in unilateral SCFE with minimal complications. Level of evidence. III

We report our early experience with a new peri-acetabular reconstruction endoprosthesis used for pelvic reconstruction after tumour resection. The outcome of 21 patients who underwent limb salvage following type II pelvic resection and reconstruction using the peri-acetabular reconstruction prosthesis between 2000 and 2006 was retrospectively reviewed. This prosthesis was designed to use the remaining part of the ilium to support a horizontally placed acetabular component secured with internal fixation and bone cement. Into this device a constrained acetabular liner is positioned which is articulates with a conventional femoral component to which a modular extension and modular head are attached. The mean follow-up was 20.5 months (1 to 77). The most common complications were deep infection, superficial wound infections, and dislocation. The mean musculoskeletal tumor society functional outcome score for the survivors was 20.1(11 to 27). We recommend the use of the peri-acetabular reconstruction prosthesis for reconstruction of large defects after type II pelvic resection, as this design has a greater inherent stability over other available prostheses

Introduction. Flexor Hallucis Longus (FHL) tendon transfer is a well-recognised salvage operation for irreparable tendon Achilles (TA) ruptures and intractable Achilles tenonopathy. Several case series describes the technique and results of arthroscopic FHL tendon transfers. We present a comparative case series of open and arthroscopic FHL tendon transfers from Southmead Hospital, Bristol, UK. Methods. For the arthroscopic FHL transfers in most cases the patients were positioned semi prone with a tourniquet. A 2 or 3 posterior portal technique was used and the tendon was secured using an RCI screw. The rehabilitation was similar in both groups with 2 weeks in an equinus backslab followed by gradual dorsiflexion in a boot over the following 6 weeks. Anticoagulation with oral aspirin for 6 weeks was used. A retrospective case note review was performed. Results. There were 12 arthroscopic (8 males, 4 female) and 16 open procedures (9 male, 7 female). Both had a mean age of 56. 1 arthroscopic FHL was lost to follow up. There were no concomitant procedures in the arthroscopic group. In the open group the TA was repaired in 7 cases (3 of these involved z-shortening). There was 1 plantaris interposition, 1 V-Y advancement and 1 gastrocnemius advancement. Degenerate tendon was excised in 1 severe re-rupture of a calcified tendinopathic achilles. There was no difference in tourniquet time between the groups (arthroscopic 69mins vs open 64 mins, p=0.64). There were no complications in the arthroscopic group. In the open group there was 1 superficial wound infection, 1 nerve injury & 1 delayed DVT at 3 months. Conclusion. Arthroscopic FHL transfer is a safe and effective surgical option when no other achilles procedures are required. The soft tissue insult is minimal, making it a good option for patients with poor soft tissues or neurovascular compromise

There are few reports of the treatment of lumbar tuberculous spondylitis using the posterior approach. Between January 1999 and February 2004, 16 patients underwent posterior lumbar interbody fusion with autogenous iliac-bone grafting and pedicle screw instrumentation. Their mean age at surgery was 51 years (28 to 66). The mean follow-up period was 33 months (24 to 48). The clinical outcome was assessed using the Frankel neurological classification and the Kirkaldy-Willis criteria. On the Frankel classification, one patient improved by two grades (C to E), seven by one grade, and eight showed no change. The Kirkaldy-Willis functional outcome was classified as excellent in eight patients, good in five, fair in two and poor in one. Bony union was achieved within one year in 15 patients. The mean pre-operative lordotic angle was 27.8° (9° to 45°) which improved by the final follow-up to 35.8° (28° to 48°). Post-operative complications occurred in four patients, transient root injury in two, a superficial wound infection in one and a deep wound infection in one, in whom the implant was removed. Our results show that a posterior lumbar interbody fusion with autogenous iliac-bone grafting and pedicle screw instrumentation for tuberculous spondylitis through the posterior approach can give satisfactory results

We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification. Osteosynthesis involved a lateral approach and the use of the AO calcaneal plate. The mean follow-up was for ten years (7 to 15). Clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS), the Creighton-Nebraska Score, the Kerr, Prothero, Atkins Score and the SF-36 Health Questionnaire. The radiological evaluation consisted of lateral and axial views of the os calcis. Arthritic changes in the subtalar joint were assessed with an internal oblique view and were graded using the Morrey and Wiedeman scale. There were 18 excellent (38.3%), 17 good (36.2%), three fair (6.3%) and nine poor (19.2%) results. Five patients had a superficial wound infection and five others eventually had a subtalar arthrodesis because of continuing pain. Restoration of Böhler’s angle was associated with a better outcome. The degree of arthritic change in the subtalar joint did not correlate with the outcome scores or Sanders’ classification. Prompt osteosynthesis should be considered for intra-articular fractures of the calcaneum in order to restore the shape of the hindfoot and Böhler’s angle

There are few reports on the treatment of pyogenic lumbar spondylodiscitis through the posterior approach using a single incision. Between October 1999 and March 2003 we operated on 18 patients with pyogenic lumbar spondylodiscitis. All underwent posterior lumbar interbody fusion using an autogenous bone graft from the iliac crest and pedicle screws via a posterior approach. The clinical outcome was assessed using the Frankel neurological classification and the criteria of Kirkaldy-Willis. Under the Frankel classification, two patients improved by two grades (C to E), 11 by one grade, and five showed no change. The Kirkaldy-Willis functional outcome was excellent in five patients, good in ten and fair in three. Bony union was confirmed six months after surgery in 17 patients, but in one patient this was not achieved until two years after operation. The mean lordotic angle before operation was 20° (−2° to 42°) and the mean lordotic angle at the final follow-up was 32.5° (17° to 44°). Two patients had a superficial wound infection and two a transient root injury. Posterior lumbar interbody fusion with an autogenous iliac crest bone graft and pedicle screw fixation via a posterior approach can provide satisfactory results in pyogenic spondylodiscitis

Hip and groin injuries are common in athletes who take part in high level sports. Adductor muscle tendon injuries represent a small but important number of these injuries. Avulsion of the tendons attached to the symphysis pubis has previously been described: these can be managed both operatively and non-operatively. We describe an uncommon variant of this injury, namely complete avulsion of the adductor sleeve complex: this includes adductor longus, pectineus and rectus abdominis. We go on to describe a surgical technique which promotes a full return to the pre-injury level of sporting activity. Over a period of ten years, 15 high-level athletes with an MRI-confirmed acute adductor complex avulsion injury (six to 34 days old) underwent surgical repair. The operative procedure consisted of anatomical re-attachment of the avulsed tissues in each case and mesh reinforcement of the posterior inguinal wall in seven patients. All underwent a standardised rehabilitation programme, which was then individualised to be sport-specific. One patient developed a superficial wound infection, which was successfully treated with antibiotics. Of the 15 patients, four complained of transient local numbness which resolved in all cases. All patients (including seven elite athletes) returned to their previous level of participation in sport. Cite this article: Bone Joint J 2015;97-B:1488–92

We have previously reported that fibular nailing in the elderly is associated with a significantly reduced complication rate and greater cost-effectiveness when compared to ORIF. The aim of this study was to compare the outcomes of fibular nailing to ORIF in patients under the age of 65. 100 patients aged 18 to 64 were randomly allocated between groups. Outcomes assessed over two years post-operatively included: development of wound complications or radiographic arthritis, the accuracy of reduction and patient satisfaction. The mean age was 44, 25% of patients were smokers and 35% had some form of comorbidity of whom three were diabetic. 27 injuries occurred after sport and two after assault the remainder occurred after a simple fall from a standing height. Superficial wound infections occurred in two patients in each group. Six patients requested removal of the nail, and six patients requested plate and screw removal. Patient reported outcome scores were comparable for the two groups. Two failures of fixation occurred in the fibular nail group; one in a patient with neuropathy. One failure of fixation occurred in the ORIF group. All other patients went on to an anatomical union without complication. Patient satisfaction with the surgical scar was higher after fibular nailing (visual analogue scale mean 0.75, range 0–5) than for ORIF (mean 1.5, range 0–7). The fibular nail allows accurate reduction and secure fixation of ankle fractures with comparable radiographic and patient-reported outcomes to ORIF at two years and a greater patient satisfaction with the appearance of the surgical scars

Background. Surgical wound closure is not the surgeon”s favorite part of the total knee arthroplasty (TKA) surgery however it has vital rule in the success of surgery. Knee arthoplasty wounds are known to be more prone to infection, breakdown or delayed healing compared to hip arthroplasty wounds, and this might be explained by the increased tensile force applied on the wound with knee movement. This effect is magnified by the enhanced recovery protocols which aim to obtain high early range of movement. Most of the literature concluded that there is no difference between different closure methods. Objectives. We conducted an independent study comparing the complication rate associated with using barbed suture (Quill-Ethicon), Vicryl Rapide (polyglactins910-Ethicon) and skin staples for wound closure following TKA. Study Design & Methods. Retrospective study where the study group included all the patients admitted to our unit for elective primary knee arthroplasty in 2015, we excluded patients admitted for partial knee arthroplasty, revision knee arthroplasty or arthroplasty for treatment of acute trauma due to the relatively higher complication rates. All the patients notes were reviewed to identify wound related problems such as wound dehiscence, wound infection and delayed healing (defined as delayed wound healing more than 6 weeks). Results. 327 patients were included in this study; 151 in Quill group, 99 in staples group and 77 in the last group where the wound closed with Rapide. We identified 9 (5.9%) cases of wound dehiscence in the Quill group, 3 cases of wound dehiscence in each of other two groups (3.8%) with Rapide and (3%) with staples. On the other hand superficial wound infection was higher with staples with 6 (6%) cases of wound infection compared to the other groups, wound infection occurred in 2 patients (2.5%) with Rapide and 5 patients (3.3%) in the Quill”s group. Most of the delayed wound healing happened after using Quill where it is reported in 5 patients (3.3%) and the lowest was in staples group with 1 patient (1%) and slightly higher percentage in Rapide group 2 patients (2.5%). The total figure of wound related problems was the highest in Quill”s group with 19 reported cases (12.5%), lower in staples” group with 10 cases (1.1%) and the lowest in Rapide”s group with 7 cases (9%). Conclusions. Our study showed different results to the reported literature suggesting that each closure method has its own advantages and disadvantages. Quill is quick, knotless and absorbable but on the other side it is significantly more expensive than other alternatives and it is associated with the highest complication rates. On the other hand Rapide is cheap absorbable alternative with the lowest percentage of wound problems but on the negative side it is time consuming. Finally staples method is the quickest, relatively cheap and rarely associated with wound dehiscence but it is not absorbable which might cause inconvenience to patients

Traditional open approaches for subtalar arthrodesis have reported nonunion rates of 5–16% and significant incidence of infection and nerve injury. The rationale for arthroscopic arthrodesis is to limit dissection of the soft tissues in order to preserve blood supply for successful fusion, whilst minimising the risk of soft tissue complications. The aim of this study was to determine the outcomes of sinus tarsi portal subtalar arthrodesis. Case records of all patients undergoing isolated arthroscopic subtalar arthrodesis by two senior surgeons between 2004 and 2014 were examined. All patients were followed up until successful union or revision surgery. The primary outcome measure was successful clinical and radiographic union. Secondary outcome measures included occurrence of infection and nerve injury. Seventy-seven procedures were performed in 74 patients, with successful fusion in 75 (97.4%). One (1.3%) superficial wound infection and one (1.3%) transient sural nerve paraesthesia occurred. Fixation with a single screw provided sufficient stability for successful arthrodesis. To our knowledge this is the largest reported series of isolated arthroscopic subtalar arthrodeses to date, and the first series reporting results of the two portal sinus tarsi approach. This approach allows access for decortication of all three articular facets, and obviates the need for a posterolateral portal, features which may explain the high union rate and low incidence of sural nerve injury in our series

Treatment of Tendo Achilles (TA) ruptures can result in considerable morbidity and has significant socio-economic implications. The ideal management of these injuries has yet to be defined. Recent studies have demonstrated that non-surgical treatment with accelerated rehabilitation may have comparable outcomes to surgery. The aim of this study was to evaluate current management and outcomes of TA ruptures at a tertiary referral centre, with a view to developing contemporary treatment guidelines. A retrospective review of TA ruptures over a 12-month period was undertaken. Patients were managed on an individual based approach with no strict management algorithm followed. Data collection included pre-injury activity level, ultrasound findings and treatment methodology. Outcome data collected included return to activity, incidence of DVT and re-rupture. Patients were followed up for an average of 2 years. Data was collected in 49 patients. 31 (63%) of these were managed non-surgically. Ruptures were most common in men (65%) at an average age of 44 yrs. Ultrasound scan at initial diagnosis was performed in 28 patients. There was an average gap in equinus of 34mm in the surgical group, while the average gap within the non-surgical group was 24mm (p=0.23). There was no association between the gap observed on ultrasound and re-rupture rate. At a median of 2 year follow up, there was no significant reduction in average time spent immobilised in a below knee splint in the surgically treated group (10.2 weeks) compared to non-surgical group (10.9 weeks, p=0.35). 86.3% of patients returned to pre-injury level of activity in the non-surgical group and 86.7% in the surgery group (p=1.0). Complications within this patient cohort consisted of one superficial wound infection and one re-rupture, both occurring within the surgical group. Within the surgical group patients were treated with direct primary repair or primary reconstruction using FHL augmentation in cases of delayed presentation. DVT was not observed in either group. Only 22.6% received thromboprophylaxis in non-surgical group compared to 61.1% in surgical group. We observed that patients within the non-surgical group demonstrated the same return to pre-injury activity as the surgically treated group and had fewer complications. The time spent immobilised was also comparable. Based on these findings, we modified guidelines and now recommend that surgery should be limited to patients with gap of greater than 20 mm in full equinus on ultrasound and in those with delayed diagnosis. We also recommend thromboprophylaxis for 2 weeks in non-surgical group

Presence of superficial wound infection following total joint replacement (TJR) increases risk of deep prosthetic infection and revision surgery. Early identification and management are advocated. We conducted an audit to identify the number of suspected wound infections, treatment received, and whether diagnosis was supported by microbiological evidence. Early complication data were collected for all TJRs completed in a 12-month period (2012, n=314). Medical records were reviewed for all complications and summarised data were compared with data from 2010/11. Forty-nine complications were recorded (47 in 2010/11) with increase in number of bacteriologically confirmed wound infections (from 2 to 6) and in number of serious wound infections (n=3). Review of medical records showed that patients were treated in the community with antibiotics despite lack of objective microbiological evidence. Two of three serious wound infections were preceded by prolonged antibiotic prescription in the community. Analysis of these results led to a new system for management of suspected wound infection in TJR patients. A ‘wound care card’ is issued at time of discharge and early assessment by a specialist orthopaedic nurse is available. Early results indicate a beneficial effect with potential to improve patient experience and long-term outcome, and to reduce overuse of antibiotics

Introduction. Patients with asymptomatic bacteriuria (ASB) have a significantly increased risk of both superficial wound infection and deep infection following arthroplasty. Debate continues as to whether treatment of pre-operative ASB reduces the risk of subsequent prosthetic joint infection. Patients/Materials & Methods. All arthroplasty units in Scotland were contacted by telephone and asked a standard series of questions regarding pre-operative urine testing in arthroplasty patients. A review of the literature was also performed. Results. All arthroplasty units in Scotland test all patients’ urine pre-operatively. 55% of clinics dipstick urine and send a midstream urine (MSU) sample if dipstick positive. 45% send an MSU without urine dipstick testing. All treat a positive MSU with oral antibiotics via the patient's GP practice. Discussion. Historically all arthroplasty patients have had urine testing as part of their routine pre-operative assessment, and this remains current British Hip Society guidance. Globally, antibiotic use is under increasing scrutiny. The evidence for treating pre-operative ASB with antibiotics appears to be lacking but this study suggests the majority of arthroplasty units continue to test for and treat ASB. Locally, this practice has been increasingly questioned by microbiologists and general practitioners. Irrespective of antibiotic treatment, we believe identifying patients with pre-operative ASB remains useful as ASB appears to represent a surrogate marker for immunocompromise. This allows patients to be warned of the increased infection risk and these patients may require altered peri-operative prophylactic antibiotic cover depending on local policy. Conclusion. Evidence for pre-operative antibiotic treatment of ASB is lacking but the majority of arthroplasty units continue this practice. Identification of pre-operative ASB is useful to identify increased infection risk and need for potential altered prophylactic antibiotic cover. We recommend formation of a consensus among arthroplasty surgeons to guide practice

Infection is a complication in hip arthroplasty. It increases mortality and morbidity and is a cause for patient's dissatisfaction. Previous Works report an infection rate between 0,4% e 1,5% in primary hip replacement and between 3,2% in revision hip replacement. The aim of this work was to access the infection rates in one hospital, compare them with the reported rates and investigate possible risk factors for infection. Electronic clinical records were consulted. Patients who underwent total hip arthroplasty (primary or revision) or hemiarthroplasty in one hospital, between the 1st February 2011 and 31st February 2013, were included. Two hundred and sixty one patients (267 surgeries) were included. Demographically, 57,5% were female patients and 42,5% were male patients with an average age of 77,1 years (± 12,3 years). Infection rate for hemiarthroplasty 3,1%, for primary total hip arthroplasty was 1,4% and for revision procedures 4,8%. A statistically significant relation was found between arthroplasty infection and superficial wound infection (p<0,001), wound dehiscence (p<0,001), and surgery performed during summer months (p<0,05). No relation was found with duration of the surgery or the hospital stay or the patient's comorbidities. The infection rate is similar to the rate reported in other clinical centres. Superficial wound complications are a good predictor for arthroplasty infection, so it is important to diagnose and start prompt appropriate management and vigilance. The increase in infection rates in summer months may be related to higher operating room temperature or less routined personal. We concluded, therefore, that infection is a complication in hip arthroplasty being prevention is a key feature when arthroplasty is performed, as well as clinical vigilance for infection signs

Calcaneal fracture fixation over the past decade has been practised via an extensile lateral incision. This can be complicated by infection and wound breakdown. We have developed a new technique for fixation of the calcaneal fractures – MACO. We utilise a 4 cm sub fibular incision to aid joint visualisation and fracture reduction. Fixation is via percutaneous screws. We analysed our prospectively collected database. 26 fractures were fixed over an 18 month period at Glasgow Royal Infirmary by three consultant surgeons. 22 patients were male and half were smokers. Mean follow up was 5 months (range 1.5 – 18 months). The mean age of our patients is 41 (range 25–68). The mean pre operative Bohler's angle was 16.7 degrees. Gissane's angle was similarly abnormal with a mean of 129 degrees. The average duration of surgery was 73 minutes (range 45–100 minutes). Post operatively, Bohler's angle was improved. The mean was 29 degrees. There was no significant difference with Gissane's angle. The mean was 128 degrees. There were no superficial wound infections. One patient was troubled by wound breakdown with subsequent deep infection. There was no need for metalwork removal in our series of patients. Two patients developed post traumatic osteoarthritis of the sub talar joint. Only one has required sub talar joint fusion. We conclude that the novel technique which we describe is successful in restoring calcaneal anatomy with few complications. Further follow up is needed to determine the long term outcomes of such surgery

The magnetically controlled growing rod (MCGR) system allows growth maintenance without the risk of anaesthesia, implant and wound complications associated with repeated surgeries. This is a medium-term report of the complications of MCGR from a multicentre study. Twenty-six patients from 6 spine institutes that are part of a multicentre study with prospectively collected data of minimum 24 months follow-up were assessed. Pre-operative, immediate post-operative and most recent spine radiographs were reviewed to measure the Cobb angle and the rod lengthening distance. The causes and any associated risk factors for re-operations were examined. Eleven patients required re-operation within the follow-up period, with a mean time to re-operation of 17 months after the initial surgery. Five were due to failure of rod distractions; 3 were due to failure of proximal foundation implants; 2 were due to rod breakage; and one case of superficial wound infection with failure of proximal fixation. Proximal junctional kyphosis occurred in 5 patients. Three had proximal anchor dislodgement and all five constructs were revised. This is the largest series with the longest follow-up to date. Our series show that the perception that using MCGR may reduce the frequency of re-operations may not be entirely true. This is the first report to examine the need for re-operation after MCGR implantation, and highlights the inherent risks of any surgical treatment in this group of patients despite the advantages of this new implant. Longer-term studies and comparisons with traditional growing rods are required

Hemorrhage and transfusion requirements in spine surgery are common. This is especially true for thoracic and lumbar fusion surgeries. The purpose of this papersi to determine predictive factors for transfusion and their effect on short-term post-operative outcomes for thoracic and lumbar fusions. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients that underwent lumbar or thoracic fusion surgery from 2010 to 2013. Univariate and multivariate regression analysis was used to determine predictive factors and post-operative complications associated with transfusion. A total of 14,249 patients were included in this study; 13,586 had lumbar fusion and 663 had thoracic fusion surgery. The prevalence of transfusion was 35% for thoracic fusion and 17.5% for lumbar fusion. The multivariate analysis showed that age between 50–60 (OR 1.38, CI: 1.23–1.54), age between 61–70 (OR 1.65, CI: 1.40–1.95), dyspnea (OR 1.11, CI: 1.02–1.23), hypertension (OR 1.14, CI: 1.02–1.27), ASA class (OR 1.73, 1.18–1.45), pre-operative blood transfusion (OR 1.91, CI: 1.04–3.49), and extended surgical time (OR 4.51, CI: 4.09–4.98) were predictors of blood transfusion requirements for lumbar fusion. While only pre-operative BUN (OR 1.04, CI: 1.01–1.06) and extended surgical time (OR 4.70, CI: 3.12–6.96) were predictors of transfusion for thoracic fusion. In contrast, higher pre-operative hematocrit was protective against transfusion. Patients transfused who underwent lumbar fusion had an increased risk to develop superficial wound infection, deep wound infection, venous thromboembolism, myocardial infarction and had longer length of hospital stay. Patients transfused who underwent thoracic fusion were more likely to have venous thromboembolism and extended length of hospital stay. However, mortality was not associated with blood transfusion. This study used a large database to characterise the incidence, predictors and post-operative complications associated with blood transfusion in thoracic and lumbar fusion surgeries. Pre- and post-operative planning for patients deemed to be at high-risk of requiring blood transfusion should be considered to reduce post-operative complication in this population

The aim of this study was to document the outcome following either early or delayed fixation for complex (AO-OTA type 43.C) fractures of the tibial plafond. From our trauma database we identified all patients who sustained a complex intra-articular fracture of the distal tibia over an 11-year period. Demographic data, fracture classification, management, complications and subsequent surgeries were recorded. The primary outcome measure was the development of early complications following surgery. The secondary outcome measure was the long-term patient reported outcome. There were 102 type C pilon fractures in 99 patients with a mean age of 42yrs (16–86) and 75.5% (n=77) were male. 73 (71.6%) patients underwent primary open reduction internal fixation (ORIF), with 20 (19.6%) undergoing primary external fixation with delayed ORIF. 34 complications were recorded in 28 (27.5%) patients. There were 18 (17.6%) infections, with a deep wound infection in 9 (8.8%) patients and a superficial wound infection in 9 (8.8%). Risk factors for developing infection were multiple co-morbidities (p=0.008), an open fracture (p=0.008), and primary external fixation with delayed ORIF (p=0.023). At a mean of 6 years (0.3–13; n=53) post injury the mean FAOS score was 76.2 (0–100), the mean FADI score was 75.7 (0–100), and 72% (n=38) of patients were satisfied. This is the largest series in the literature documenting the outcome following fixation for type C tibial pilon fractures. Despite the severity of these injuries, we have demonstrated a satisfactory outcome using primary early fixation in the vast majority of cases

Introduction. Hip and groin injuries are common in athletes participating in high level sports. Adductor muscle tendon injuries represent a small but important number of these injuries. Avulsion injuries involving tendons attaching to the symphysis pubis have previously been described and can be managed both operatively and non-operatively. The aim is to describe a rare variant of this injury; complete avulsion of the adductor sleeve complex including adductor longus, pectineus and rectus abdominus. A surgical technique is then outlined which promotes a full return to pre-injury level of sporting activity. Patients/Materials & Methods. Fifteen high level athletes with an MRI confirmed acute adductor complex avulsion injury (6–34 days) were identified from the institution's sports injury database over a 10 year period. All underwent surgical repair. The operative procedure comprised anatomical attachment of the avulsed tissues in all cases (plus mesh reinforcement of the inguinal wall in 7 patients). All underwent a standard format of rehabilitation which was then individualised to be sport specific. Results. One patient developed a superficial wound infection which was successfully treated with antibiotics. 12 out of 15 patients complained of transient local numbness which resolved in all cases. All patients (including 7 elite athletes) returned to their previous level of participation in sport. Discussion. Injury to the triad of adductor longus, pectineus and rectus abdominus should be considered in athletes presenting with groin pain following forced adduction. All athletes underwent early surgical exploration, previous studies have shown prolonged symptoms in early conservative management. Adductor tenotomy has shown previously acceptable results but may be less suitable in elite athletes with higher functional demands when operative repair has been shown to be successful. Conclusion. Operative repair of acute sleeve avulsion of the adductor complex in high level athletes, followed by sport specific rehabilitation promotes return to previous level of participation in sport

Computer assisted surgery (CAS) has gained popularity in orthopaedics for both total knee (TKA) and total hip arthroplasty (THA) in the past decades as a stereotactic device that provides the surgeon with real-time feedback on implant position based on electromagnetic or infrared based instruments. The purpose of this study was to assess the effect of CAS on 30-day complication rates following THA and TKA. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify all patients that underwent THA and TKA from 2011 to 2013, as well as any complication they had within 30-days of their surgery. Univariate and multivariate regression analysis was used to compare the post-operative complications in patients whose surgery involved the use of CAS with those by conventional surgical techniques. We identified 104,550 patients who had THA (42,275 patients) and TKA (62,275 patients) procedures in the database between 2011 and 2013. Computer Assisted Surgery was used in 1,120 THA and 2,173 TKA procedures. There were higher overall adverse events (OR 1.40, CI: 1.22–1.59) in the Conventional group when compared to CAS for TKA. The rate of overall minor events (OR 1.38, CI: 1.21–1.58) and requirements for blood transfusion (OR 1.44, CI: 1.25–1.67) were higher in the Conventional group compared to the CAS group for TKA. However, rate of re-operation was significantly higher in the CAS group for TKA (OR 1.60, CI: 1.15–2.25). The results also showed higher overall adverse events (OR 2.61, CI: 2.09–3.26) in the Conventional group when compared to CAS for THA. The rate of overall minor events (OR 2.72, CI: 2.16–3.42) and requirements for blood transfusion (OR 3.27, CI: 2.52–4.25) was higher in the Conventional group whereas superficial wound infections (OR 0.46, CI: 0.46–0.81) were shown to be higher in the CAS group. The result also showed slightly longer operative times in CAS for both THA and TKA. This study analysed a large patient database involving multiple institutions and surgeons and found that, overall, the use off CAS in primary total hip and total knee arthroplasty reduced the number of adverse events in the first 30-days postoperatively, compared to conventional surgical techniques. However, CAS was associated with an increased number of reoperations, superficial infections and operating time. The clinical benefits and disadvantages of CAS should be considered by arthroplasty surgeons when determining the potential benefit-cost ratio of this technology

Aim. To investigate the effectiveness of silver coated prostheses in preventing periprosthetic infection in a high-risk group. Methods. We have used silver coated prostheses in 48 endoprosthetic replacements in whom there would be a high expected risk of infection. Results. Between 2006 and 2009 48 patients had silver coated prostheses inserted; 19 primaries, 10 single-stage revisions, and 19 second-stage revisions. Of these, only one (2%) required removal following overwhelming coliform infection. There were four superficial wound infections in the primary group, none in the single-stage group, and 5 in the 2 stage group. Of these patients, one died of metastases, 7 settled with antibiotics ⊞/⊟ wound washout, and one patient is undergoing investigation. Discussion. These early results suggest that silver coating may not prevent infection but seems to help treatment of it by allowing control with simple measures (washout). The cost of the silver coating is about £300. It will be cost effective if it reduces the overall infection risk by 1%

Lateral malleolar plating is associated with complication rates of up to 30%. The fibular nail is an alternative fixation technique, requiring a minimal incision and tissue dissection, with the potential to reduce the incidence of complications. We reviewed our results of 105 unstable ankle fractures fixed with the Acumed fibular nail between 2002 and 2010. The mean age was 65 years and 72% of patients had significant systemic medical comorbidities. A number of different locking screw configurations were assessed over the study period. A proximal blocking screw resulted in satisfactory stability in 93%, single locking screws in 86%, but nailing without locking in only 66%, leading to the development of our current technique. Of the twenty-one patients treated with this technique there have been no significant complications, and only two superficial wound infections. Good fracture reduction was achieved in all of these patients. The mean physical component SF12, Olerud and Molander and Foot and Ankle Outcome scores were 46, 65 and 83 respectively. The outcomes of unstable ankle fractures managed with the fibular nail are encouraging, with good radiographic and functional outcomes and minimal complications. This technique should be considered in the management of debilitated patients with unstable ankle fractures

Ganz peri-acetabular osteotomy is commonly used to treat symptomatic hip dysplasia. It aims to increase the load bearing contact area of the hip to reduce the risk of subsequent osteoarthritis. In this study we assess the radiographic and clinical results of the procedure since its introduction to our unit. All patients undergoing Ganz osteotomies at our unit were followed up prospectively. Data collected included patient demographics and pre- and post-operative functional scores (Harris and Non-arthritic hip scores). In addition, acetabular correction was evaluated on pre-and post-operative radiographs (using Centre-Edge angle and Tonnis angle). Complications were also noted. Overall 50 procedures were performed between 2007 and 2013 with median follow-up of 3 years (1 – 7 years). The majority of patients (90%) were female. Average age at time of surgery was 29 years (16–49). There were significant improvements in pre- and post-operative median functional scores (Modified Harris Hip Score = 49 versus 64, p=0.001), Non-arthritic Hip Score = 42 versus 56, p=0.007). Median Centre Edge Angle improved from 16 degrees pre-operatively (range = 7–31 degrees) to 30 degrees post-operatively (18–33) degrees), p<0.0001. Similarly, pre-operative Tonnis angle improved from 18 degrees (9–38) to 7 degrees (2–14), p<0.0001. Five patients developed post-operative complications: 2 superficial wound infection, 1deep infection requiring hip washout and antibiotic treatment and 2 patients subsequently requiring total hip replacements. We have shown that the Ganz peri-acetabular osteotomy can be effective for the treatment of painful hip dysplasia improving both functional and radiographic outcomes. However, patient selection is a key factor

Because life expectancy is increasing, the number of primary knee arthroplasties performed is projected to increase 673% by 2030, according to Westrich et al. Also, Toulson et al. in a recent study predict that the incidence of deep infection associated with primary total knee arthroplasty ranges from 1% to 2%. Periprosthetic knee infection is one of the most dramatic and difficult to manage complications following total knee arthroplasty. Therefore, periprosthetic knee infection will continue to be a significant complication and an economic burden in the future. Our objective was to identify the risk factors that may provide greater likelihood of infection and thus select high-risk patients and to take maximum prevention strategies. Case-control study, between infected and non infected patients, undergoing primary total knee arthroplasty between January 2008 and January 2013. The risk factors evaluated were: duration of hospital stay, surgery duration, prophylactic antibiotics and timing for administration, volume of blood transfusion, autologous blood recovery system use, anesthetic technique, ASA classification, Diabetes Mellitus, Obesity (BMI>30), immunosuppression and history of any infection in the month preceding surgery. The presence of infection was defined by the criteria of the Center for Disease Control for Nosocomial Surgical Site Infections1. Statistical analysis IBM SPSS Statistics 20 (Fisher's exact test, Mann-Whitney U test and Student's t-test). Statistical significance for p ≤ 0.05. We evaluated 540 patients with a mean follow-up of 56 months. We identified 21 deep infections (3,8%), and 35 superficial wound infections and found a positive correlation between infection and obesity (p <0.01), immunosuppression (p <0.01), volume of blood transfusion (p=0.02), history of any infection in the month preceding surgery (p <0.01). We found a negative correlation with the use of a autologous blood recovery system (p <0.01). Other factors, commonly referred in the literature, showed no association or did not reach statistical significance. The incidence of periprosthetic knee infection after primary total knee arthroplasty stays high. The presence of obesity, immunosuppression, blood transfusion, history of any infection in the month preceding surgery were identified as significant risk factors for infection to occur. The identification, modification or eviction of the risk factors implied are essential to reduce and prevent infection in arthroplasty

Introduction. Anterior cruciate ligament (ACL) reconstructive surgery is one of the most commonly performed surgical procedures. Synthetic ACL repair surgery with the Lars ligament is designed to repair, rather than replace, the torn ACL. Once the ACL is repaired, the level of function, biomechanical attributes and proprioception should be similar to the pre-injury state. All patients in this cohort have undergone surgical repair of the torn ACL with synthetic Lars ligament augmentation. The indications and surgical technique will be outlined. Patients have been assessed at follow-up with KOOS and Marx scores, which reflect the surgical outcome. The preliminary results with a six-month minimum follow-up will be presented. The results reflect previous published studies that show that surgical repair of the torn ACL with Lars ligament augmentation, can reliably and reproducibly stabilise the knee and allow an early return to sport. Complications include one septic arthritis, superficial wound infections and improperly placed bone tunnels. Synthetic ACL repair using the Lars ligament is a reprodicible technique that allows a rapid post-operative rehabilitation and avoids all complications relating to graft harvesting. The indications and the surgical technique are quite specific and must be adhered to in order to achieve the best results

Background. Revision THA presents significant challenges for the surgeon when the proximal femur is deficient or mechanically unreliable. The aim of this study is to assess the clinical and functional results of the use of tumor enndoprosthesis to reconstruct the proximal femur when there is massive bone loss. Patients and Methods. A prospective study was conducted involving 10 cases. The follow up of the cases ranged from 12 months to 30 months with a mean period of an average of 23months. The indications for revision surgery were aseptic loosening in 9 cases and septic loosening in one case Harris hip score was used for pre and postoperative clinical evaluation of the patients. Results. At the latest follow up the Harris Hip scores improved from a preoperative average of 16 (range, 3-47), to a postoperative average of 75.6 (range, 66-94). The complications that we encountered in the study included one case of superficial wound infection, another case developed sciatic nerve palsy postoperatively. No other complications were reported. Conclusion. Revision hip replacement in proximally compromised femurs presents a significant surgical challenge. When there is massive proximal femoral bone loss proximal fitting revision stems do not achieve adequate fixation hence the use of tumor prosthesis is indicated

Innominate Osteotomy first described by Salter is one of the commonest procedures performed for treatment of Developmental Dysplasia of the Hip (DDH) in children. We recently described a less invasive technique for Innominate Osteotomy, which significantly reduces the operation time without compromising outcome (J Pediatr Orthop B. 2010 Jul;19(4):318–22). As part of the evolution of this procedure we now routinely use bioabsorbable pins (INION OTPS PIN, made from co-polymers of L-lactic acid, D-lactic acid and trimethylene carbonate) instead of K-wires to secure the graft. We prospectively followed-up 120 consecutive cases done using bioabsorbale pins over a 2 year period. The surgical technique was as described in our less invasive innominate osteotomy paper. Average age at surgery was 24 months (18–52) with mean follow-up period of 15 months (6–24 months). The mean preoperative acetabular index was 36.2. o. Our results show a mean acetabular index of 18.7. o. (P< 0.0001) at latest follow-up with no loss of correction. We recorded three superficial wound infections (one MRSA), all resolved uneventfully. There was no foreign body reaction. The use of bioabsorbable pins eliminates the need for a second anaesthetic to remove the pins with significant cost benefit without compromising outcome

Background. Adductor muscle and tendon injuries are commonly seen in sport. Complete adductor avulsions have been described and can be managed non-operatively or operatively. A rare variant of this injury is the complete avulsion of the adductor complex with the pectineus and rectus abdominus amounting to a complete sleeve avulsion from the pubis. This is a severe injury that is increasingly recognised due to improved imaging and lower diagnostic threshold. Purpose. We describe the surgical management of twelve athletes with this severe injury. Study design. Prospective case series - Level of evidence, 4. Methods. All the injuries were prospectively collected onto our institutional pelvic sports injury database. This series summarises the outcome in twelve consecutive cases where surgery was undertaken after presentation with an acute avulsion (6–34 days) in athletes. The procedure comprised anatomical reattachment of the avulsed tissues with mesh reinforcement of the inguinal wall in seven patients. An independent physiotherapist reviewed all patients. Results. One patient developed a superficial wound infection treated with antibiotics. Transient complaints of local numbness were common but all twelve sportsmen returned to high-level sport (five elite) at an average of thirteen weeks (10–21 weeks). Conclusion. Awareness of the possibility of this complex injury is important and there should be a low threshold for investigation. In elite athletes operative intervention is associated with good clinical outcomes and successful return to sport

Objective: To assess functional outcome and complications in patients with Weber C fracture following syndysmotic screw removed. Patients & Methods: Forty three consecutive patients with closed Weber C type ankle fractures between 2002–20003 were studied. The syndysmotic screw was removed at 6–12 weeks time post operatively. Postoperative complications and functional outcome were studied. Results: Following removal of the syndysmotic screw 6 patients had superficial wound infection, 4 patients had pain due to instability, one patient had DVT and one patient had broken screw. The functional outcome using ankle scores compared to the other studies in the literature did not show any significant difference. Conclusion: Syndysmotic screw removal has significant morbidity. Guidelines with randomised control studies are recommended

We undertook a prospective randomised trial to determine the outcome of locked intramedullary fixation vs. plating of displaced shortened mid-shaft clavicle fractures. The primary outcome measure was the Constant shoulder score, while secondary outcome measures included the Oxford shoulder score, union rate, and complication rates. Thirty-two patients were recruited to the trial; 17 randomised to locked intramedullary fixation and 15 randomised to plating. Mean age was 29.3years (13 to 53 years). Mean follow-up was 12.4 months (5 to 28 months). There was no significant difference in Constant scores (p = 0.365) and no significant difference in Oxford scores (p = 0.686). There was 100% union in both groups. In the intramedullary group, there was one case of soft tissue irritation that settled after the pin was removed, one pin backed out and had to be revised with another pin. There were three superficial wound infections resulting in plate removal and 8 plates (53%) were removed. Locked intramedullary fixation and plating are equally effective in the management of shortened displaced mid-shaft clavicle fractures

Aim:. To review the short to medium term radiological, clinical and functional outcomes of reconstructive surgery for severe forefoot deformities in patients with Rheumatoid arthritis. Methods:. We conducted a review of prospectively collected data of patients with Rheumatoid arthritis who received reconstructive surgery for forefoot deformities. Patients requiring metatarso-phalangeal joint arthrodesis and excision of the lesser metatarsals for hallux valgus, dislocation of the lesser metatarso-phalangeal joints and intractable plantar keratosis were included. The patients were followed up at 2 weeks, 6 weeks, 3 months and 6 months. X-Rays were performed preoperatively, postoperatively, at 6 weeks, 3 months and 6 months follow-up. Patients completed a SF36, and AOFAS (American Orthopaedic Foot and ankle Score) forefoot score preoperatively and at 6 months postoperatively. Results:. Ten feet in eight patients were included in the study. Follow-up was for a minimum of 6 months. All patients were female, with an average age of 58 years (34–69 years). Radiologically there was an average correction in the hallux valgus angle from 48 degrees to 15 degrees. The inter-metatarsal angle improved from 14 to 9 degrees. Objective scores were significantly improved. The mean SF36 score pre-operatively was 36 (24–54) and 67 (54–82) post operatively (P < 0.05). The AOFAS score improved from a mean of 32 (28–50) pre operatively to 74 (64–78) post-operatively (p < 0.05). One patient required re-operation for further metatarsal shortening due to ongoing pain and two patients required oral antibiotics for minor superficial wound infections. All hallux metatarsophalangeal joint arthrodesis procedures united in a mean time of 3.5 months. Conclusion:. Forefoot reconstruction in these very symptomatic, disabled patients resulted in significant deformity correction and improvement in function and pain. The complication rate was low. Adequate resection of the lesser metatarsals is necessary to avoid ongoing pain from the phalanx articulating with the metatarsal

Background. Intravenous and topical tranexamic acid (TXA) has become increasingly popular in total joint arthroplasty to decrease perioperative blood loss. In direct comparison, the outcomes and risks of either modality have been found to be equivalent. In addition, current literature has also demonstrated that topical TXA is safe and effective in the healthy population. To our knowledge, there is a scarcity of studies demonstrating the safety of topical TXA in high risk patient populations undergoing total joint arthroplasty or revision joint arthroplasty. The purpose of this study is to determine the safety of topical TXA in patients undergoing total or revision arthroplasty that are also on chronic anticoagulant or anti-platelet therapy. Methods. We performeded a retrospective review of patients undergoing primary and revision total hip or knee arthroplasties that received topical TXA (3g/100mL NS) from November 2012 to March 2015. All patients, regardless of co-morbidities, were included in the study population. Patients were divided into 3 groups:. Group 1: Patients without any antiplatelet or anticoagulant therapy within 90 days of surgery. Group 2: Patients receiving antiplatelet therapy (Aspirin and/or Plavix) within 90 days of surgery. Group 3: Patients receiving anti-coagulant therapy within 90 days of surgery (low molecular weight heparin, unfractionated heparin, warfarin, dabigatran, rivaroxaban, apixaban). Chart review analyzing ICD-9 and ICD-10 coding was then utilized to establish any peri-operative complications within the 30 day post-operative period in all groups. Complications amongst the groups were evaluated via chi-squared testing as well as multivariate linear regression. Review of current literature and CMS protocols were used to establish reportable peri-operative complications. Wound infections, thromboembolic events and vascular complications such as myocardial infarction, pulmonary embolism, deep venous thrombosis, stroke, aortic dissection were included. Results. During the study period, a total 1471 total joint arthroplasties were performed on 1324 patients (88.7% knee arthroplasty, 11.3% hip arthroplasty). Group 1 included 1033 patients who were not on any prior anti-platelet or anticoagulant therapy. Group 2 included 254 patients receiving chronic antiplatelet therapy 90 days prior to surgery. Group 3 included 184 patients receiving chronic anticoagulant therapy 90 days prior to surgery. No statistically significant differences were found between the groups for any of the included peri-operative complications. The most common complication occurring amongst all the groups was superficial wound infection, which occurred in a total of 60 (4.1%) patients in contrast to 18 (1.2%) patients who sustained an acute deep peri-prosthetic infection. Twenty (1.4%) patients sustained an ultrasound proven deep vein thrombosis, with the highest prevalence occurring in those patients receiving no anticoagulation prior to surgery (15/20, 75%), however this was not statistically significant following linear regression analysis. Conclusions. To our knowledge, this is the first study that demonstrates that topical tranexamic acid is safe to use in so-called high risk patients who are being treated prior to surgery with anti-platelet or anti-coagulation therapy

Introduction. Growing evidence in the literature suggests better clinical and functional outcomes and lower re-rupture rates with repair compared to non-operative treatment of ruptured Achilles tendon. There are however, concerns of wound infection, nerve injury and scar tenderness with the standard open and percutaneous techniques of repair. We aim to evaluate clinical and functional outcomes and complications in patients treated with minimally invasive Achillon device. Materials and Methods. Prospectively collected clinical data was reviewed of all consecutive patients who underwent repair of the ruptured Achilles tendon using the Achillon device. Patients were contacted using a postal questionnaire for assessment of their functional status using the validated Achilles Tendon Total Rupture Score (ATRS) and compared with their uninjured side. The outcomes were compared to the published results. Results. We present patient demographics; and clinical and functional outcomes of 140 consecutive patients who underwent repair of ruptured Achilles tendon using the minimally invasive technique between June 2007 to August 2010. Our complication rate was of two-three percent each of proximal DVT, scar sensitivity, superficial wound infection and no re-rupture after a minimum of 6 months. There was no case of nerve injury leading to permanent neurological deficit. Discussion. This study demonstrates good clinical and functional outcomes from using the Achillon device in repair of ruptured Achilles tendon with a low complication rate comparable to other published series. We recommend Achillon device as a safe minimally invasive technique for repair of the ruptured Achilles tendon

Introduction. Extensor digitorum brevis (EDB) transfer is a useful method for treating chronic ankle instability in selected patients. It adds strength to the anterolateral capsule and provides proprioceptive feedback to functionally unstable ankles. Method. A single surgeon of case series of patients undergoing EDB transfer for chronic ankle instability following sporting injuries between January 2003 and July 2011 was reviewed. All patients underwent arthroscopic procedures in a day case setting. Outcomes were measured using return to sporting activity and the Karlsson functional scoring system. Results. 67 patients underwent unilateral EDB transfer over the 102 month period. 49 patients were male and all patients were aged less than 45. Minimum follow up was 6 months and all patients were discharged by 15 months (median follow up 9 months). Post operative assessment demonstrated normal range of ankle movements in all cases. At 6 months all patients had returned to sporting activity, achieving pre injury activity by 9 months. Karlsson scores were above 85.3 minor complications were seen - a superficial wound infection, limited paraesthesia of a branch of the superficial peroneal nerve and a case of complex regional pain syndrome which underwent full remission with early multimodal therapy. Conclusion. This study forms the largest published single surgeon series for EDB transfers. The data contributes to the body of evidence supporting EDB transfers as a safe and effective day case procedure for treatment of chronic ankle instability in selected patients

Introduction. Massive rotator cuff tears in the patient who is too young for a reverse shoulder replacement are a challenging situation. A technique using a ‘Grammont osteotomy’ of the acromion has been developed to allow a comprehensive approach, the so called “Full Monty”. Aim. To document the functional outcome of patients undergoing an acromial osteotomy for the repair of massive tears of the supraspinatus. Methods. Ten patients undergoing this procedure where entered in to the study. The mean age of the patients was 57 years (+/−16) and all bar one were male. Each patient had a pre-operative American Shoulder Elbow Score (ASES), Oxford Shoulder score (OSS), and range of movement documented. These outcome measures were repeated at a minimum of two years, as well as a patient satisfaction questionnaire. Results. The mean ASES preoperatively was 7(+/− 6) and 23(+/−3) post-operatively (p< 0.001). The mean pre-operative OSS was 22(+/−5) and 43(+/−4) post-operatively (p<0.001). 80% of patients deemed their treatment to be “successful” and 90% would recommend the procedure to a friend in the same plight. The mean post-operative forward flexion achieved was 153° (+/−58) and the mean abduction was 142° (+/−37). All patients could sustain a 1kg weight at arms length at 90° of abduction. One patient suffered a superficial wound infection and one patient had a non-union at the osteotomy site. Conclusion. These results suggest that this technique is a good surgical option for a patient with a “massive” rotator cuff tear that is not amenable to standard surgical techniques

Introduction: Total knee arthroplasty in obese patients remains a challenge to most surgeons. Surgical complication rates as well as perioperative morbidity are higher than total knee arthroplasty in the nonobese. The purpose of this paper is to review our experience with total knee arthroplasty in superobese patients (BMI> 50). Methods: From 1998–2005, 84 patients underwent 148 knee arthroplasties. Sixty-four patients underwent simultaneous bilateral total knee arthroplasties and 20 patients underwent unilateral knee arthroplasties. They were compared with similar group of nonobese patients who underwent knee arthroplasties during the same time period. All patients received combined regional and general anesthesia. Results: Mean follow-up was 3.8 years (2–7). Knee society scores improved by 36 points in the superobese (pre-op 47 to 83 post-op) and by 45 points in the non-obese (pre-op 47 to 93 post-op) (p< .05). There was a greater incidence of complications in the superobese group, namely superficial wound infections and deep vein thrombosis. There was late loosening in three tibial components and instability in two patients that required revision in the superobese group. No reoperations in the nonobese group. Conclusion: Although total knee arthroplasty may be safely performed in the superobese, it may be complicated by infection, loosening, instability, and lower knee scores

The aim of this study was to investigate the risk factors, financial costs and outcomes associated with infection after hip fracture surgery. Prospective hip fracture data from the University Hospital, Nottingham, was analysed, assessing patients with either deep or superficial wound infections admitted over a five year period. 3605 patients underwent hip fracture surgery. 2.3% of these patients developed a wound infection of which 1.2% were deep wound infections. 75% of infections were due to Staphylococcus aureus and 50% of all infections were caused by methicillin-resistant Staphylococcus aureus. No statistically significant risk factors for the development of infection were identified in this study. Length of stay, cost of treatment and pre-discharge mortality were all increased with deep infection. Deep wound infection increased the average length of stay from 28 days to 100 days. This quadrupled the ward costs. The mean overall hospital cost of treating a hip fracture complicated by deep wound infection was £34903 compared to £8979 fro those who did not develop infection. Pre-discharge mortality increased from 24.2% in the control group to 30% in the infected group (p<0.006). MRSA significantly increased costs, LOS, and pre-discharge mortality compared with non-MRSA infection. These results show the huge impact that infection after hip fracture surgery has both on mortality and hospital costs

We prospectively analyzed 83 patients who underwent ceramic-on-ceramic THA using preassembled (n = 22) or modular acetabular components (n = 61) between June 2010 and June 2012. No radiographic evidence of progressive radiolucency, osteolytic lesions, acetabular fractures, or component migration was detected in either group. Furthermore, no patient required revision surgery for instability or ceramic breakage. Table 1 shows the mean postoperative HHS, WOMAC score, and acetabular component inclination and anteversion in groups A and B. No significant differences in mean postoperative HHS (P < 0.056), WOMAC score (P < 0.258), acetabular component inclination (P < 0.827), or anteversion (P < 0.549) were observed between the two groups according to the independent sample t-test. However, the chi-square (Fisher's exact) test showed a significant difference between the two groups with respect to the gender of the patients (P < 0.001, Table 2). These findings indicate that half of the women had smaller acetabular diameters accommodating a cup size of only 48–50-mm. Thus a preassembled ceramic liner is a very good option for women with a small acetabulum, which could permit the use of a larger femoral head (36-mm) with thin-walled acetabular components. In contrast, the component-specific complications between the two groups were quite similar. One patient (group B) had transient squeaking that disappeared after a few months. One patient (group B) had a mild limp caused by abductor muscle weakness, and one patient (group B) had a superficial wound infection that was treated with local debridement and antibiotics. Early dislocation (P < 0.488) occurred in three patients (one in group A and two in group B). Two patients (one in group A and one in group B) reported postoperative falling events at their bedside. The other in group B was a female with rheumatoid arthritis, which can lead to a much higher risk of dislocation due to soft tissue laxity around the hip joint. All of these patients were treated by closed reduction without further incident. Three patients (one in group A and two in group B) had mild iliopsoas pain (P < 0.488) that was not associated with loosening; however, the pain did not limit their activities (Table 3). In conclusion, we found no significant differences in the mean postoperative radiographic or functional outcomes or complications between the two groups, showing satisfactory performance at the 2 year follow up. Only the gender of the patient was significantly different between the two goups, demonstrating that a larger number of women had smaller acetabular diameters accommodating a cup size of only 48–50-mm. Although a preassembled cup with a 36-mm ceramic liner has proven safety in the short term, future research should focus on its long-term risks

We have carried out a retrospective review of 11 Souter-Strathclyde primary total elbow arthroplasties in ten patients with osteoarthritis, over a period of nine years. The diagnosis was primary osteoarthritis in nine elbows and post-traumatic arthritis in two. The mean follow-up was 68 months (15 to 117). Although no patient was symptomatic, radiological review revealed evidence of loosening affecting three humeral and two ulnar components, one of which subsequently failed and was revised at 97 months. There were no dislocations, deep infections or mechanical failures. Complications included two superficial wound infections and two neurapraxias of the ulnar nerve which resolved. This study shows that the unlinked Souter-Strathclyde total elbow arthroplasty can be considered for patients with osteoarthritis and gives good symptomatic relief and improvement in function

Seventy-eight children, with 79 femoral fractures, treated with titanium elastic intramedullary nails were reviewed for complications. Insertion site symptoms (41), malunion (8), refracture (2), transient neurological deficit (2), superficial wound infection (2), and reoperation prior to union (10). Malunion/loss of reduction was increased with mismatched nails (p=0.02) and comminution (p=0.02). Insertion site symptoms were increased with nail ends that were bent (p=0.02), or > 10mm prominent (p=0.002). Nails remain implanted in 25 children without problems. Nail ends should lie against the femur to avoid insertion site symptoms. Nails of different diameters should not be implanted. Comminuted fractures require close monitoring

A recognised treatment for severe sub-talar arthritis is joint fusion. This can be performed using a well established open technique or achieved through an arthroscopic approach. The aim of this retrospective study was to investigate the results of arthroscopic sub-talar arthrodesis performed by a single surgeon in our institution. 13 arthroscopic sub-talar joint fusions were performed over a 2 year period in patients presenting with isolated arthritis of the joint in question. All arthrodeses were carried out using two posterolateral portals and one posteromedial portal and fixed with two single 7 mm partially threaded cancellous screws. Outcome measures included the American Foot and Ankle (AFOS) score, time to union and post-operative complications. No patients were lost to follow-up. 12 out of 13 arthrodeses went onto clinical and radiological fusion. The AFOS score improved from36 (range 32–50) pre-operatively to 75 (range 65–80) at final follow up. Complications included 1 non-union, 1 DVT and 1 superficial wound infection. 3 patients have had metalwork removed secondary to screw irritation. The results of subtalar arthrodesis performed using an arthroscopic technique is comparable with an open approach and provides high patient satisfaction

Total ankle replacement (TAR) is increasingly offered as an alternative to ankle fusion for the management of severe ankle arthritis. As with all other types of joint arthroplasty, there are risks involved and complications that occur; these increase with case complexity. We present the complications and management from a single-centre series. Since 2006, we have performed 150 Mobility TARs with up to 4 years' follow-up. We have excluded 16 that are part of a separate RCT and 10 with less than 3 months' follow-up. 124 TARs were included in our study (117 patients). Three ankles (2.4%) had superficial wound infections treated successfully with antibiotics. One ankle (0.8%) required an arthroscopic washout and debridement but the implant was retained. 11 ankles (8.9%) had a periprosthetic fracture: One was intraoperative; 10 were postoperative (2 fixed). Four patients (3.2%) developed CRPS. One ankle required fusion surgery (following subsidence of the talar component) with another one pending revision (ligament instability causing implant displacement). No patient had a symptomatic deep vein thrombosis or thromboembolic event. Our figures are comparable with other series. Our complication rate has not changed significantly over time. Our results, at present, suggest that most complications (98%) with the Mobility TAR can be satisfactorily managed without having a detrimental effect on the implant. There have been proven and promising results with total ankle replacement. However, there is a significant complication rate that must be made clear to the patient via informed consent; the rate still remains higher than for hip and knee arthroplasty

Aim. A prospective cohort of patients undergoing total ankle arthroplasrty for arthritis following pilon fractures was included in the present study. This group of patients generally have poor soft tissue envelope and have had previous surgical interventions prior to the ankle arthroplasty, making the arthroplasty more difficult as well as prone to complications. Methods. The data collected included patient demographics, American Orthopaedic Foot and Ankle Score (AOFAS) and patient reported outcomes (FAOS, SF-36, patient satisfaction) The data was collected preoperatively and at 1 & 2 years postoperatively. The minimum follow-up period was 2 years post-operatively. Results. A total of 167 total ankle arthroplasties were performed by the senior author between Jan 2006 and June 2010. Of this cohort, the indication for 12 arthroplasties was arthritis following pilon fractures of the distal tibia. The average of the patients at the time of the surgery was 64.2yrs. The average number of previous surgeries prior to the ankle arthroplasty was 1.5. There were significant improvements in the AOFAS scores from an average of 18 to 75 at final review. The WOMAC scores improved from 31 to 71 for pain, stiffness improved from 31 to 60 and function improved from 33 to 63. The improvement of the SF36 and patient satisfaction score is similar to the ones for primary ankle osteoarthritis. The complications were: 1 case of superficial wound infection which settled with antibiotics, one fracture of medial malleolus and one case of undisplaced distal tibial fracture treated conservatively to union. Conclusion. The Indications for TAR can be safely broadened to include younger patients with arthritis following pilon fractures of the tibia. The Outcomes after TAR for patients with arthritis following pilon fractures are comparable to those for primary osteo arthritis of the ankle

Aim. We report the results of Cobb I procedure and Rose calcaneal osteotomy for stage II posterior tibial dysfunction in a consecutive series of thirty patients. Methods. These patients were reviewed prospectively after average of 30 months (range: 12-92 months). An experienced independent, biomechanics specialist carried out the ultrasound examination to assess dynamic function of the posterior tibial tendon at final follow-up. Results. Twenty-eight patients were available for final follow-up. Two patients died of unrelated causes. Mean age was 60 years (range: 40-81 years). Average AOFAS score improved from 53.6 pre-operatively to 89.8 at final follow-up. Twenty-five (89%) patients were able to perform single heel raise. Six (22%) were using some form of orthotics at final follow-up. All calcaneal osteotomies united. On ultrasound examination, the posterior tibial tendon was intact in all patients and it was found to be mobile in twenty-six (93%) patients. There was one superficial wound infection and two prominent screws were removed. Three patients had subtalar joint arthritis. The surgical intervention improved the quality of life in all but two patients and only two patients were not satisfied with the surgery. Conclusion. These results suggest that a combination of Cobb I procedure and Rose Calcaneal osteotomy is a safe, effective, reliable and attractive option for the treatment of stage II posterior tibial tendon dysfunction, which provides dynamic function of posterior tibial tendon without sacrificing the primary function of long flexor tendons in foot and ankle

Techniques for fixation of the lateral malleolus have remained essentially unchanged since the 1960s, but are associated with complication rates of up to 30%. The fibular nail is an alternative method of fixation requiring a minimal incision and tissue dissection, and has the potential to reduce complications. We reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. The mean age of the patients was 64.8 years (22 to 95), and 80 (76%) had significant systemic medical comorbidities. Various different configurations of locking screw were assessed over the study period as experience was gained with the device. Nailing without the use of locking screws gave satisfactory stability in only 66% of cases (4 of 6). Initial locking screw constructs rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable. Overall, seven patients had loss of fixation of the fracture and there were five post-operative wound infections related to the distal fibula. This lead to the development of the current technique with a screw across the syndesmosis in addition to a distal locking screw. In 21 patients treated with this technique there have been no significant complications and only one superficial wound infection. Good fracture reduction was achieved in all of these patients. The mean physical component Short-Form 12, Olerud and Molander score, and AAOS Foot and Ankle outcome scores at a mean of six years post-injury were 46 (28 to 61), 65 (35 to 100) and 83 (52 to 99), respectively. There have been no cases of fibular nonunion. Nailing of the fibula using our current technique gives good radiological and functional outcomes with minimal complications, and should be considered in the management of patients with an unstable ankle fracture

Introduction. The incidence of distal femoral fractures amongst elderly patients is likely to rise due to increased life expectancy. This study reports on the outcome of a series of distal femoral fractures treated by retrograde femoral nailing and then to compare the results for these patients with a series of patients with a proximal femoral fracture. Materials and/Methods. In this longitudinal cohort study, 36 patients with extra-articular distal femoral fractures were treated with a solid retrograde femoral nail. Data was collected prospectively and then compared to proximal femoral fractures (2426) treated by the same surgeon treated over the same time period. Results. Within the distal femoral group 97% of the patients were female, with a mean age of 81 years. The mean length of hospital stay amongst the distal femoral group was slightly higher (19 days) compared to the proximal femoral group (18 days). All the post-operative complications were higher amongst the distal femoral group which included deep vein thrombosis 8% vs 2%, pneumonia 5% vs 3%, superficial wound infection 5% vs 3% and deep wound infection 2% vs 1%. 5% of patients in the proximal femoral group required revision surgery whereas none in the distal femoral group did. The survival analysis curve indicated to an increased trend in mortality amongst the distal femoral group however due to the small sample size this did not reach statistical significance. Conclusions. Our study shows that there is a significant morbidity and mortality amongst patients who have sustained a distal femoral fracture. Given the significant risk that elderly patients have we propose that distal femoral fractures should be treated with prompt surgical fixation with an emphasis on early rehabilitation and safe discharge

Conventional growing rods are the most commonly used distraction-based devices in the treatment of progressive early-onset scoliosis. This technique requires repeated lengthenings with the patient anaesthetised in the operating theatre. We describe the outcomes and complications of using a non-invasive magnetically controlled growing rod (MCGR) in children with early-onset scoliosis. Lengthening is performed on an outpatient basis using an external remote control with the patient awake. Between November 2009 and March 2011, 34 children with a mean age of eight years (5 to 12) underwent treatment. The mean length of follow-up was 15 months (12 to 18). In total, 22 children were treated with dual rod constructs and 12 with a single rod. The mean number of distractions per patient was 4.8 (3 to 6). The mean pre-operative Cobb angle was 69° (46° to 108°); this was corrected to a mean 47° (28° to 91°) post-operatively. The mean Cobb angle at final review was 41° (27° to 86°). The mean pre-operative distance from T1 to S1 was 304 mm (243 to 380) and increased to 335 mm (253 to 400) in the immediate post-operative period. At final review the mean distance from T1 to S1 had increased to 348 mm (260 to 420). Two patients developed a superficial wound infection and a further two patients in the single rod group developed a loss of distraction. In the dual rod group, one patient had pull-out of a hook and one developed prominent metalwork. Two patients had a rod breakage; one patient in the single rod group and one patient in the dual rod group. Our early results show that the MCGR is safe and effective in the treatment of progressive early-onset scoliosis with the avoidance of repeated surgical lengthenings.

The effects of using a tourniquet during total knee arthroplasty were studied in 80 patients randomly allocated to two groups, either with or without a tourniquet. The groups were similar in mean age, gender, preoperative knee score and radiographic grading and the patients were all operated on by the same surgeon using one type of prosthesis. There was no significant difference between the two groups in operating time or total blood loss but postoperative pain was less in the patients in whom a tourniquet had not been used. They achieved straight-leg raising and knee flexion earlier and had fewer superficial wound infections and deep-vein thromboses. Total knee arthroplasty can be safely performed without the use of the tourniquet with the benefit that several adverse effects associated with its use can be avoided

Purpose of study:. A retrospective clinical and telephonic survey of AMIS patients. Minimally Invasive Anterior Hip Replacements have been performed according to the AMIS technique in two centres in South Africa on a regular basis since 2 February 2007. We report on the first 335 cases that were done from February 2007 till October 2009 in these two centers, by two surgeons. Description of methods:. The data reported from these patients was collected from clinical notes, hospital records and telephonic questionnaires. Of the 335 cases that were performed data could be collected from 283 patients. Patients lost to follow up were 16 deceased, 24 could not be reached and 12 others had co-morbidities like Alzheimers, Total deafness and CVA. Summary of results:. The data collected includes: Patient demographics, diagnosis, co-morbidities. We also collected data of the surgical procedures including the duration of the procedure, prosthesis used, and hospital stay. We also collected data of the functional activities and time duration to achieving this. These activities include driving a car, shopping, domestic work, gardening and sport like hiking and golf. Complications reported include superficial wound infection 4, deep infections 1, dislocation 6, hematoma 8, impingement 1 and fractures 4. Total rate of revision was 2.47 %. Analysis of the causes of revision were; subsidence and dislocation 3, anterior acetabular impingement 1, proximal femoral loosening and persistent thigh pain 1, fractured ceramic liner 1, displaced acetabular component 1. Discussion:. The anterior approach for total hip replacement is a new method that preserves all the musculature around the hip joint with resultant benefits. This is a demanding technique that is reflected in the results. 80 % of the revisions were encountered in the first 50 cases

The aim of this study is to review the functional outcome of the patients treated with Posterior Lumbar Interbody Fusion for FBSS. This is a retrospective review of prospectively collected data of 39 patients diagnosed with FBSS and treated with PLIF between June 2000 and December 2008 by the senior author in our unit. Pain and function were evaluated by VAS for Back (VAS-BP) & leg pain (VAS-LP), Oswestry disability index (NDI) and SF-36 questionnaires, and were completed pre- & post-operatively. There were 39 patients (20 women & 19 men) and mean age at operation was 47.3 years (range of 32 to 76.1 years). Mean duration of follow-up was 39.14 months (range 5.21 -73.5 months). Thirty-one patients were diagnosed as Post laminectomy syndrome and 8 patients as post-discectomy syndrome. The mean pre and post-operative ODI values were 54.13 and 29.14 respectively. The mean pre-operative VAS back and leg pain scores were 7.38 and 6.51 respectively. The mean post-operative VAS for back and leg pain scores were reduced to 4.05 (Pre-op:7.38) and 3.69 (Mean pre-op 6.51)respectively. The mean preoperative SF-36 bodily pain component score was 27.42 and the mean postoperative score was 40.50. Four patients had uncomplicated dural tears that resolved completely. Two patients had superficial wound infection that resolved with oral antibiotics. PLIF is one of the safe and effective treatment option for FBSS and it has shown good results in our series

Introduction:. Intraoperative cell salvage involves the collection of blood directly from the operative field. The purpose of this study was to determine if its use reduces the need for postoperative allogenic blood transfusion, assess any adverse events and its effect on duration of postoperative stay in primary hip arthroplasty. Patients and Methods:. We prospectively examined the effect of intraoperative cell salvage on the need for postoperative allogenic blood transfusion. Between February 2009 and August 2010, a total of 77 patients who underwent primary total hip arthroplasty were included in the study, under the care of the senior author (KB). All patients had a diagnosis of osteoarthritis. Intraoperative cell salvage was used in 38 patients and not used in 39 patients. We prospectively collected data on patient demographics, ASA grade, preoperative and postoperative haematological features, number of units of packed red cells transfused and the volume of intraoperative reinfused cell salvaged blood. Total inpatient stay and any postoperative adverse events were recorded. Results:. No patients in the cell salvage group required postoperative allogenic blood transfusion compared to three patients (7.7%) in the conventional group. Postoperative decrease in haemoglobin was less in the cell salvage group (2.57 vs. 3.3 g/dL). The mean length of postoperative inpatient stay was shorter in the cell salvage group (5.1 vs. 6.41 days). Three patients in the cell salvage group had adverse events (1 UTI, 1 hyponatraemia, 1 colonic pseudo-obstruction). Three patients in the conventional group experienced adverse events (2 superficial wound infections, 1 DVT). An average of 361 mls of cell salvaged blood was reinfused (110–900 mls). Conclusions:. We have found that the use of intraoperative cell salvage in patients undergoing primary total hip arthroplasty reduces the need for post operative allogenic blood transfusion with no increase in adverse events when compared to conventional measures of blood preserving techniques

Introduction. Rivaroxaban, an oral factor Xa inhibitor, has been approved by USFDA for prophylaxis of deep vein thrombosis (DVT) and pulmonary embolism (PE) in hip and knee arthroplasties. Its indication in hip fracture surgery has been recently recommended in Asian venous thromboembolism (VTE) guidelines. Phase II dose-ranging study demonstrated that 5 mg rivaroxaban is as effective as enoxaparin for VTE prophylaxis with lower incidence of bleeding complication than the recommended 10 mg dose. Rivaroxaban is recommended to be given 6–8 hours after operation. However, many surgeons are hesitated to follow this guideline since it might increase post-operative blood loss and wound complication. Elderly patients, such as hip fracture patients, are generally at more risk of bleeding and wound complications. These patients may benefit from using the delayed and reduced-dose regimen. Methods. Since July 2011, all eligible hip fracture patients treated by single group of surgeons were given 5mg daily dose of rivaroxaban for VTE prophylaxis. Initial dose of rivaroxaban was given after drain had been removed (24–36 hours post-operatively) and continued for 14 days. Inclusion criteria are femoral neck fracture or intertrochanteric fracture in patients age 60 and over. Exclusion criteria are pathologic fracture, reoperation for failed fixation, chronic anticoagulant therapy, and allergy to rivaroxaban. Criteria by Aniwan and Rojnackarin were used for clinical diagnosis of DVT and PE. Suspected case of DVT and PE were sent for confirmation with Doppler U/S and Pulmonary Artery CT scan, respectively. All bleeding and wound complications were recorded. Numbers of blood transfusion were also recorded. Patients were followed for at least 6 weeks, all complications were recorded. Results. There were 79 hip fracture patients matching our criteria. They were composed of 54 femoral neck fractures and 25 intertrochanteric fractures. Mean age of patients was 76.3 years. All femoral neck fractures were treated with bipolar hemiarthroplasty and intertrochanteric fractures were treated with short cephalomedullary nail. Two patients (2.6%) were compatible with clinical criteria of DVT. However, Doppler ultrasound examinations do not demonstrate thrombus or intraluminal filling defect. There was no suspected case of PE. There was no major hemorrhagic wound complication requiring reoperation. Minor wound complications include 7 (8.9%) cases of prolong serous oozing and 1 (1.3%) superficial wound infection. Extrasurgical site bleeding includes 1 (1.3%) upper GI bleeding and 2 (2.5%) hematuria. None of the patients received more than 2 units of blood transfusion. Discussion and Conclusion. Delayed and reduced-dose regimen of rivaroxaban is effective for VTE prophylaxis in hip fracture patients. There is no major hemorrhagic wound complication. Nonetheless, extrasurgical site bleeding is frequent. Further randomized comparative study with larger number of patients should be performed to demonstrate whether the benefits of the modified regimen existed or not

We reviewed our results and complications of using a pre-bent 1.6mm Kirschner wire (K-wire) for extra-articular metacarpal fractures. The surgical procedure was indicated for angulation at the fracture site in a true lateral radiograph of at least 30 degrees and/or in the presence of a rotatory deformity. A single K-wire is pre-bent in a lazy-S fashion with a sharp bend at approximately 5 millimetres and a longer smooth curve bent in the opposite direction. An initial entry point is made at the base of the metacarpal using a 2.5mm drill by hand. The K-wire is inserted blunt end first in an antegrade manner and the fracture reduced as the wire is passed across the fracture site. With the wire acting as three-point fixation, early mobilisation is commenced at the metacarpo-phalangeal joint in a Futuro hand splint. The wire is usually removed with pliers post-operatively at four weeks in the fracture clinic. We studied internal fixation of 18 little finger and 2 ring finger metacarpal fractures from November 2007 to August 2009. The average age of the cohort was 25 years with 3 women and 17 men. The predominant mechanism was a punch injury with 5 diaphyseal and 15 metacarpal neck fractures. The time to surgical intervention was a mean 13 days (range 4 to 28 days). All fractures proceeded to bony union. The wire was extracted at an average of 4.4 weeks (range three to six weeks). At an average follow up of 8 weeks, one fracture had to be revised for failed fixation and three superficial wound infections needed antibiotic treatment. With this simple and minimally invasive technique performed as day-case surgery, all patients were able to start mobilisation immediately. The general outcome was good hand function with few complications

Background. Distal tibial metaphyseal fractures pose many complexities. This study assessed the outcomes of distal tibial fractures treated with percutaneously inserted medial locking plates. Methods. Eighteen patients were selected based on the fracture pattern and classified using the AO classification and stabilised with an AO medial tibial locking plate. Time to fracture union, complications and outcomes were assessed with the American Orthopaedic Foot and Ankle Society ankle score at 12 months. Results. Sixteen of the 18 patients achieved fracture union, with 1 patient lost to follow up. Twelve fractures united within 24 weeks, with an average union time of 23.1 weeks. Three delayed unions, two at 28 weeks and one at 56 weeks. The average time to union was 32 weeks in the smokers and 15.3 weeks in the non-smokers. Five of the 18 patients (27%) developed complications. One superficial wound infection and one chronic wound infection, resulting in non-union at 56 weeks, requiring revision. Two patients required plate removal, one after sustaining an open fracture at the proximal end of the plate 6 months after surgery (post fracture union) and the other for painful hardware. One patient had implant failure of three proximal diaphyseal locking screws at the screw head/neck junction, but successful fracture union. The average AOFAS ankle score was 88.8 overall, and 92.1 in fractures that united within 24 weeks. Conclusions. Distal tibial locking plates have high fracture union rates, minimum soft tissue complications, and good functional outcomes. The literature shows similar fracture union and complication rates in locking and non-locking plates

Background. Total ankle replacement (TAR) is increasingly offered as an alternative to ankle fusion for the management of severe ankle arthritis. As with all other types of joint arthroplasty, there are risks involved and complications that occur; these increase with case complexity. We present the complications and management from a single-centre series. Results. Since 2006, we have performed 150 Mobility TARs with up to 4 years' follow-up. We have excluded 16 that are part of a separate RCT and 10 with less than 3 months' follow-up. 124 TARs were included in our study (117 patients). Three ankles (2.4%) had superficial wound infections treated successfully with antibiotics. One ankle (0.8%) required an arthroscopic washout and débridement but the implant was retained. 11 ankles (8.9%) had a periprosthetic fracture: One was intra-operative; 10 were post-operative (2 fixed). Four patients (3.2%) developed CRPS. One ankle required fusion surgery (following subsidence of the talar component) with another one pending revision (ligament instability causing implant displacement). No patient had a symptomatic deep vein thrombosis or thromboembolic event. Discussion. Our figures are comparable with other series. Our complication rate has not changed significantly over time. Our results, at present, suggest that most complications (98%) with the Mobility TAR can be satisfactorily managed without having a detrimental effect on the implant. There have been proven and promising results with total ankle replacement. However, there is a significant complication rate that must be made clear to the patient via informed consent; the rate still remains higher than for hip and knee arthroplasty

Techniques for fixation of fractures of the lateral malleolus have remained essentially unchanged since the 1960s, but are associated with complication rates of up to 30%. The fibular nail is an alternative method of fixation requiring a minimal incision and tissue dissection, and has the potential to reduce the incidence of complications. We reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. The mean age of the patients was 64.8 years (22 to 95), and 80 (76%) had significant systemic medical comorbidities. Various different configurations of locking screw were assessed over the study period as experience was gained with the device. Nailing without the use of locking screws gave satisfactory stability in only 66% of cases (4 of 6). Initial locking screw constructs rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable. Overall, seven patients had loss of fixation of the fracture and there were five post-operative wound infections related to the distal fibula. This lead to the development of the current technique with a screw across the syndesmosis in addition to a distal locking screw. In 21 patients treated with this technique there have been no significant complications and only one superficial wound infection. Good fracture reduction was achieved in all of these patients. The mean physical component Short-Form 12, Olerud and Molander score, and American Academy of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean of six years post-injury were 46 (28 to 61), 65 (35 to 100) and 83 (52 to 99), respectively. There have been no cases of fibular nonunion. Nailing of the fibula using our current technique gives good radiological and functional outcomes with minimal complications, and should be considered in the management of patients with an unstable ankle fracture.

Purpose. We conducted a prospective study to investigate the role of the LARS ligament system to reconstruct the posterior cruciate ligament and the postero-lateral corner of the knee. We present a prospective single surgeon case series to evaluate early clinical and functional outcomes of postero-lateral corner and posterior cruciate ligament reconstruction in the knee using the LARS (ligament Augmentation and Reconstruction System) artificial ligament. 23 patients with multi-ligament knee injuries or isolated PCL injuries were treated with a mean follow up of 8 months (range: 2-37 months). Outcomes were assessed using the modified International Knee Documentation Committee score, and a modified Tegner- Lysholm score. 2 patients had acute reconstructive surgery within 7 days of injury, 5 patients within 3 months (semi-acute) and 16 were chronic cases that were operated on after three months from the date of injury. The LARS ligament reconstruction achieved a significant improvement between preoperative and postoperative assessment in relation to knee stability, function and patient satisfaction. The sooner the patients were treated the greater the improvements in functional scores were noted. Most patients achieved a full functional range of movement within six months. We had 2 complications, one superficial wound infection and one stiff knee requiring a manipulation. To date we have had no LARS ligament failures. In the short term the LARS functions well, with high clinical patient satisfaction, no signs of progressive laxity, synovitis or failure. We found no significant difference in functional score post reconstruction between the isolated PCL reconstructions and the multi ligament reconstructions. Our results show no early signs of the problems associated with synthetic grafts used in the past. Such grafts appear to be an attractive alternative to the use of autografts and allografts

Background. A number of studies have reported on the early failure of the Oxford unicompartmental knee arthroplasty. However, less evidence is available regarding the outcome following revision of failed unicompartmental knee prostheses to total knee arthroplasty. Study aims. The study aims were to determine the time to failure and mode of failure for the Oxford unicompartmental knee arthroplasty and to assess the short-term outcome following revision surgery. Methods. Details of consecutive patients undergoing revision of an Oxford unicompartmental knee arthroplasty to a total knee arthroplasty at our centre between January 2000 and December 2009 were collected prospectively. Data was collected on patient demographics, time to revision, and revision indication. Clinical, functional and radiological outcome following revision were assessed. Results. Of 494 Oxford unicompartmental knee arthroplasties implanted, 20 (4.0%) were revised to a total knee arthroplasty. Mean age at revision was 63.5 yr and 50% were male. Mean time to revision surgery from the index procedure was 3.2 yr (range 1.2-6.2 yr). The commonest reason for revision was aseptic loosening of the femoral (n=9) or tibial component (n=2). All patients were revised to a cemented total knee arthroplasty. Three patients required femoral and/or tibial augments. During follow-up (range 0.5-4.5 yr) there was one case of superficial wound infection. One patient underwent a further revision for instability 1.5 years following the initial revision procedure. Discussion. The present study demonstrates most failures of the Oxford unicompartmental knee arthroplasty are due to aseptic component loosening, occur within four years, and do not require femoral or tibial augmentation when revised. These findings are consistent with other published reports regarding the early failure of this prosthesis. The short-term outcome following revision surgery appears to be good, however longer follow-up periods are required to determine if these results continue

Aim. The purpose of this study was to quantify the number of children treated with ESIN (elastic stable intra-medullary nails) at our institution and to determine what proportion of these nails have been removed and the time and difficulty taken to do so. Methods. Patients treated with ESIN between 2000 and 2005 were identified by database search. Their notes were reviewed to record patient and initial nailing details, and timing, difficulty and length of metalwork removal procedures. Complications leading to premature removal or following nail extraction were noted. Results. Eighty-seven patients were identified who fitted our study criteria (68% male, 32% female). Mean age was 10.9 years (4.7–15.9 years). Twelve of the procedures were for open fractures. Seventy-nine patients underwent nail removal at our institution. Four were followed up elsewhere and a decision to leave the nails in was made in another four patients (usually underlying bone pathology). Four patients had surgery earlier than planned to deal with implant problems: 3 to address prominent nails and 1 for re-fracture. The nails were removed at a mean of 8 months after insertion. Mean time taken to remove the metalwork was 25 minutes (10 to 75 minutes). Eight of the 79 removal procedures were graded as difficult, with one being extremely difficult: this was not predictable from pre-operative radiographs. There were 2 complications following metalwork removal. One was a re-fracture through a unicortical bone cyst 2 years after removal, which was successfully treated with ESIN again. The other was a superficial wound infection, which settled with antibiotics. Conclusion. It is routine policy at our institution to remove ESIN after fracture healing, but it should be noted that removal procedures can be difficult and lengthy. There is, however, a low complication rate following removal, and routine follow-up may not be necessary

Purpose: Scarf osteotomies are commonly performed in adults with symptomatic bunions. We have reported the radiological and clinical outcome of this procedure in the treatment of moderate to severe hallux valgus among adolescent children. Methods: Data was collected retrospectively from a tertiary referral children hospital between April 2001 and June 2006. The pre and postoperative intermetatarsal angle (IMA), hallux valgus angle (HVA) and distal metatarsal articular angle (DMAA) were determined. Patients were followed up for a mean of 8.6 months (3–18). Results: 23 scarf osteotomies were performed in 16 patients with a mean age of 14.3 years (12–18). The mean pre operative IMA of 14.4 degrees was improved to a postoperative value of 9.3 degrees, p< 0.0001. The mean HVA angle was improved from 34.7 to 16.5 degrees, p< 0.0001. The DMAA was improved from 13.1 to 8 degrees, p< 0.0001. There were 2 cases of superficial wound infections successfully treated with oral antibiotics. One patient developed a complex regional pain syndrome that resolved with physiotherapy and analgesia. Conclusion: We believe that scarf osteotomy is a safe and effective option for the management of the adolescent symptomatic bunions. Significance: There are no published reports in the English literature of scarf osteotomy in the management of adolescent children with symptomatic hallux valgus. The aim of this paper is to report the radiological and clinical outcome of scarf osteotomy in the treatment of moderate to severe hallux valgus among adolescent children

Intraoperative cell salvage involves the collection of blood directly from the operative field. The purpose of this study was to determine if its use reduces the need for postoperative allogenic blood transfusion, assess any adverse events and its effect on duration of postoperative stay in primary hip arthroplasty. We prospectively examined the effect of intraoperative cell salvage on the need for postoperative allogenic blood transfusion. Between February 2009 and August 2010, a total of 77 patients who underwent primary total hip arthroplasty were included in the study, under the care of the senior author (KB). All patients had a diagnosis of osteoarthritis. Intraoperative cell salvage was used in 38 patients and not used in 39 patients. We prospectively collected data on patient demographics, ASA grade, preoperative and postoperative haematological features, number of units of packed red cells transfused and the volume of intraoperative reinfused cell salvaged blood was. Total inpatient stay and any postoperative adverse events were recorded. No patients in the cell salvage group required postoperative allogenic blood transfusion compared to three patients (7.7%) in the conventional group. Postoperative decrease in haemoglobin was less in the cell salvage group (2.57 vs. 3.3 g/dL). The mean length of postoperative inpatient stay was shorter in the cell salvage group (5.1 vs. 6.41 days). Three patients in the cell salvage group had adverse events (1 UTI, 1 hyponatraemia, 1 colonic pseudo-obstruction). Three patients in the conventional group experienced adverse events (2 superficial wound infections, 1 DVT). An average of 361mls of cell salvaged blood was reinfused (110–900mls). We have found that the use of intraoperative cell salvage in patients undergoing primary total hip arthroplasty reduces the need for post operative allogenic blood transfusion with no increase in adverse events when compared to conventional measures of blood preserving techniques

Minimally Invasive foot surgery remains controversial. Potential benefits include a reduced incidence of wound complications, faster return to employment and normal footwear. There are no studies published regarding the results of minimally invasive dorsal cheilectomy. Patients and Methods. Thirty eight patients with painful grade I hallux rigidus underwent dorsal cheilectomy between April 2006 and June 2010. Minimally invasive cheilectomy (MIC) was introduced in August 2009. AOFAS scores, satisfaction, return to normal shoes and employment were assessed. Results. Twenty two patients had open cheilectomy (OC) whilst 16 had MIC. Mean follow-up was 6 months for the MIC group and 35 months for the OC group. Mean AOFAS score was 75/100 (SD 17) in the MIC group and 70/100 (SD 18). Patients rated their satisfaction as 9.1/10 for MIC and 8.6/10 for OC. There was no significant difference in time to return to normal shoes (P = 0.32) or employment (P = 0.07). Two patients (one MIS, one OC) had a superficial wound infection which resolved with oral antibiotics. One patient had a first metatarsophalangeal joint fusion in the MIS group. Two patients in the OC group went on to have a first metatarsophalangeal joint fusion and one underwent joint resurfacing. Discussion. These results suggest MIC has comparable early results to OC. Larger studies are required to further establish the benefits of MIC. Conclusion. Minimally invasive dorsal cheilectomy seems to offer a safe alternative to open cheilectomy with promising early results. Patient satisfaction with this procedure is very high

Introduction. Ankle replacement is a major surgery with significant soft tissue dissection and bleeding. The skin quality is often poor in these patients due to age, edema, venous congestion, arteriopathy or previous procedures and soft tissue injury. The chances of wound infection increase with delayed wound healing. Absorbent non-adherent dressing (ABD) and VAC dressing applied in theatre after ankle replacement were assessed in a cohort of 147 patients with wound complications, pain, satisfaction and length of stay as outcome measures. Patients and methods. 71 consecutive patients were treated with ABD post-operatively after ankle replacement. The practice was then changed to VAC dressings for 76 consecutive patients. 44 patients had additional procedures performed with ankle replacement (11 from ABD group and 33 from VAC group). Retrospective analysis of prospectively collected data was performed. All patients had daily pain score, wound status, hospital stay, satisfaction and range of movement recorded. Results. Patients with VAC had mean pain score of 3/10 post operatively compared with 6/10 with ABD. There was a significant difference between the length of stay between the groups (p=0.02). The average stay of stay was 9 days with ABD and 7 days with VAC dressing. One of the patients with VAC dressing had blisters and 1 patient developed a superficial wound infection. Of the ABD group, 3 patients developed blisters and 7 patients had wound complications after ABD. Range of movement was similar in both groups of patients. Patient's satisfaction with VAC dressing was 8/10. Conclusion. VAC is better than ABD as primary dressing after ankle replacement

Introduction. Minimally Invasive foot surgery remains controversial. Potential benefits include a reduced incidence of wound complications, faster return to employment and normal footwear. There are no studies published regarding the results of minimally invasive dorsal cheilectomy. Patients and Methods. Thirty eight patients with painful grade I hallux rigidus underwent dorsal cheilectomy between April 2006 and June 2010. Minimally invasive cheilectomy (MIC) was introduced in August 2009. AOFAS scores, satisfaction, return to normal shoes and employment were assessed. Results. Twenty two patients had open cheilectomy (OC) whilst 16 had MIC. Mean follow-up was 6 months for the MIC group and 35 months for the OC group. Mean AOFAS score was 75/100 (SD 17) in the MIC group and 70/100 (SD 18). Patients rated their satisfaction as 9.1/10 for MIC and 8.6/10 for OC. There was no significant difference in time to return to normal shoes (P = 0.32) or employment (P = 0.07). Two patients (one MIS, one OC) had a superficial wound infection which resolved with oral antibiotics. One patient had a first metatarsophalangeal joint fusion in the MIS group. Two patients in the OC group went on to have a first metatarsophalangeal joint fusion and one underwent joint resurfacing. Discussion. These results suggest MIC has comparable early results to OC. Larger studies are required to further establish the benefits of MIC. Conclusion. Minimally invasive dorsal cheilectomy seems to offer a safe alternative to open cheilectomy with promising early results. Patient satisfaction with this procedure is very high

Introduction:. The aim of this study was to identify the rate of complications of total ankle replacement in a single Centre to help with informed patient consent. Methods:. Between 2008 and 2012, 202 total ankle replacements (TARs) were performed by 4 surgeons at our Institute. Data was collected on all patients; demographics, arthritic disease, pre-operative deformity, prosthesis and all early and late complications. Results:. 4 surgeons (A, B, C, D) performed 63, 55, 48 and 36 TARs (178 De Puy Mobility and 24 Corin Zenith). 130 patients had primary osteoarthrosis, 35 had rheumatoid and 36 had post traumatic osteoarthrosis. There were no differences in patient demographics for each surgeon. There were 3 deep infections (A, B, C, D: 1,0,2,0). There were 18 medial malleolar fractures (8 intra-operative [4,1,1,2], 3 early (< 3 months) [1,1,0,1] and 7 late (> 3 months) [2,2,2,1]). There were 2 lateral malleolar fractures, both intra-operative (0,0,1,1). There were 15 patients who developed superficial wound infections, which resolved fully with oral antibiotics (4,3,4,4). A further 7 patients had a delay to wound healing (wound not fully healed at 3 months) (4,0,2,1); 2 of these developed deep infection and failed. 22 patients had persistent medial gutter pain (9,4,5,4); all had undergone Mobility TAR. 4 patients developed recurrent edge loading and have had to be revised (4 converted to TTC fusion) (2,0,2,0). We report complications in 32% of patients. Overall 9 TARs failed and underwent revision to fusion (2,2,5,0). Conclusion:. We report an overall complication rate of 32% following TARs, however most are minor and don't affect clinical outcome. We had a 1.5% deep infection rate. Complication rates were comparable between 4 surgeons. There was a difference in medial gutter pain rate between implants (13% v 0% Mobility to Zenith). This data provides detailed complication rates for informed consent

The objective of this study was to assess the clinical outcome and efficacy of the X-Stop™ interspinous implant. 67 patients (36 male, 31 female) with mean age of 62.4 years (range 50–94 years) and radiologically proven lumbar stenosis, underwent X-Stop™ implantation during the period of June 2004 to June 2007. Patients were assessed pre-operatively and post-operatively at 3, 6 and 12 months using the Back and Sciatica Questionnaire, the Oswestry Disability and the SF12 questionnaire. Patient’s satisfaction was assessed in each visit. Minimum follow up 2 years in 45 patients and 1 year in 22 patients. 70% had significant improvement in the walking distance following the operation. With the Back and Sciatica Questionnaire the average preoperative VAS of back and leg pain was 7.1 and 6.7 and improved to 2.5 and 2.6 postoperatively. 86% patient had improvement in their ODI score by 14% and more with average pre and postoperative score 44% (range18%–84%) and 15.8% (range 0%–61%) respectively. With the SF12 questionnaire 68% patients had significant improvement in physical score and 77% in the mental score. Complications included five superficial wound infections and one wound haematoma. One patient required revision surgery. This new surgical technique for the treatment of lumbar spinal stenosis, is simple and effective with minimum complications

If the lower re-rupture in operative treated patients was an effect of tendon-end apposition, then patients in whom that could be demonstrated in equinus by ultrasound could be equally well treated non-operatively without the attendant surgical risk. All patients undergoing ultrasound for a suspected Achilles tendon repair between January 2000-2005 were included. Patients with a residual gap, 5mm or more in equinus; were treated by surgical repair. Those with a gap of less than 5mm were treated non-operatively. We excluded patients with no rupture, partial rupture and musculo-tendinuous junction (MTJ) tears. We recorded the following: clinical findings, ultrasound measurements of tendon gap in neutral and equinus, distance of rupture from distal insertion, the treatment and complications. All patients were followed up to a minimum of 6 months. 156 patients were treated for a clinical Achilles tendon rupture during the study period. We excluded 5 patients with no rupture on ultrasound, 15 with a MTJ tear, 7 with a muscle tear and 4 patients did not follow the protocol. 125 patients comprising 88 males and 37 females were entered into the study. 67 patients were treated operatively (37 open, 30 percutaneous) and 58 non-operatively. There was no significant difference between the 2 groups with respect to age, sex and injury mechanism. Two patients in the non-operative group had a re-rupture (3.4%) compared with 1 (1.5%) in the non-operative group. There were 2 incidences of superficial wound infection and 2 of temporary dorsal foot numbness in the operative. One patient in the non-operative group had a DVT. There was no significant difference for any of the complications between the two groups. It may be possible to reduce the risk of re-rupture and surgery using dynamic ultrasound to determine which treatment the patient receives

Since November 2003 there have been 62 Metacarpophalangeal Joint (MCPJ) replacements carried out on 16 patients at Macclesfield District general hospital. 11 of the patients were female and 5 were male. The mean patient age at procedure was 64.9 years, with an age range of 28 to 80. Of the 62 MCPJ replacements carried out, 58 (93.5%) were as a result of rheumatoid arthritis, with only 4 (6.5%) as a result of osteo-arthritis. The primary objective of this study is to assess their outcomes to date. Data was collected retrospectively by means of case note review. Outcomes measured were patient rating of pain and function at post operative review and post operative complications. All operations were carried out by a single surgeon, using his standard operative technique, and all replacements used the Neuflex Finger Joint Implant System. All 16 patients attended for post operative review. At the time of discharge 13 patients rated their outcome as excellent to good, 1 patient was deceased and 2 patients are currently under follow up with no reported complications. Mean time to discharge was 19 months (2–68). Of the total 62 joints replaced, 10 revisions were carried out. Of these, 3 were as a result of dislocation, 6 were for subluxation and 1 as a result of failure of the prosthesis. There were 3 other post operative complications; 1 was for superficial wound infection, 1 resulting from a prominent prosthesis and 1 hypertrophic scar. Results showed that 81.3% of patients rated their range of movement as good to excellent and 87.5% reported an improvement in pain. Overall, 81% of patients rated their outcome at discharge as good to excellent. From the data available we conclude that the Neuflex system is an effective treatment method with a low complication rate

Seven patients who had malignant proximal femoral tumours were selected for resection and limb salvage with a modular megaprosthesis. Histopathological diagnosis confirmed one solitary bone metastasis from renal cell carcinoma, one dedifferentiated chondrosarcoma, two primary non-Hodgkin lymphomas non-responsive to adjuvant chemo- and radiotherapy and three low-grade chondrosarcomas. The mean age at the time of surgery was 53.5 years. Post-operative survival averaged 54.5 months. The mean functional status score was satisfactory. There was no local tumour recurrence or dislocation of the prosthesis. There were one superficial wound infection and one post-surgical haematoma. Care must be taken in selecting patients to for resection of the proximal femur and implantation of modular megaprostheses. We reserve such treatment only for tumours that, because of the histopathological diagnosis and spread, chemotherapy or radiotherapy alone is not enough. Modular megaprosthesis is currently the method of choice in the treatment of malignant proximal femoral tumours. With this implant joint function can be restored after wide resection, too, offering a valid alternative to the bony massive allografts that are characterised by a high rate of complications and failure
