Aims. This study aimed to investigate the clinical characteristics and outcomes associated with culture-negative limb osteomyelitis patients. Methods. A total of 1,047 limb osteomyelitis patients aged 18 years or older who underwent debridement and intraoperative culture at our clinic centre from 1 January 2011 to 31 December 2020 were included. Patient characteristics, infection eradication, and complications were analyzed between culture-negative and culture-positive cohorts. Results. Of these patients, 264 (25.2%) had negative cultures. Patients with a culture-negative compared with a culture-positive status were more likely to have the following characteristics: younger age (≤ 40 years) (113/264 (42.8%) vs 257/783 (32.8%); p = 0.004), a haematogenous aetiology (75/264 (28.4%) vs 150/783 (19.2%); p = 0.002), Cierny-Mader host A (79/264 (29.9%) vs 142/783 (18.1%); p < 0.001), antibiotic use before sampling (34/264 (12.9%) vs 41/783 (5.2%); p<0.001), fewer taken samples (n<3) (48/264 (18.2%) vs 60/783 (7.7%); p<0.001), and less frequent presentation with a sinus (156/264 (59.1%) vs 665/783 (84.9%); p < 0.001). After initial treatments of first-debridement and antimicrobial, infection eradication was inferior in culture-positive osteomyelitis patients, with a 2.24-fold increase (odds ratio 2.24 (95% confidence interval 1.42 to 3.52)) in the redebridement rate following multivariate analysis. No statistically significant differences were found in long-term recurrence and complications within the two-year follow-up. Conclusion. We identified several factors being associated with the culture-negative result in osteomyelitis patients. In addition, the data also indicate that culture negativity is a positive prognostic factor in early infection eradication. These results constitute the basis of optimizing clinical management and patient consultations. Cite this article: Bone Joint J 2024;106-B(7):720–727

Background. Giant cell tumours of bone (GCT) are benign bone tumours with a locally aggressive character. Local recurrence is considered the main complication of surgical treatment and is described in up to 50% of patients. Intralesional curettage with the use of adjuvants like phenol or polymethylmetacrylate (PMMA) is recommended as initial treatment, significantly decreasing the risk of recurrence. However, risk factors for local recurrence in skeletal GCT have not yet been firmly established and a golden standard for local therapy remains controversial. Objective. The identification of risk factors predisposing for an increased risk of local recurrence. In addition, different surgical techniques are compared to identify the optimal surgical approach for the identified risk factors. Methods. In a retrospective study all 215 patients with bone GCT treated between 1964 and 2009 in one centre were included, of which 193 were suitable for analysis. All patients had minimal follow-up of 12 months (mean 115; range 12–445). Using a Kaplan Meier survival analysis recurrence free survival rates were calculated. Cox-regression was used to determine the influence of different types of therapy, the use of adjuvants, and various patient and tumour characteristics. Results. The mean local recurrence rate for all patients was 35.2% (n=68, 95%CI: 28.3–42.1). Recurrence rate after wide resection was 0.17 (n=6, 95%CI: 0.04–0.29), after curettage with adjuvants 0.32 (n=42, 95%CI 0.24–0.41) and after curettage alone 0.74 (n=20, 95%CI: 0.57–0.91, p < 0.001). Soft tissue extension (Hazard Ratio: 3.8, p < 0.001), localisation in radius and ulna (HR: 2.6, p=0.013), and surgical experience (HR: 2.2, p=0.022) were identified as significant general risk factors for local recurrence. For intralesional resection, Campanacci grade III (HR: 3.9, p=0.019) and location in axial skeleton (HR: 3.3, p=0.016) additionally significantly increased this risk. Comparing treatments our data showed that curettage followed by adjuvants was superior to curettage alone (p < 0.004), and the application of both phenol and PMMA did not present a significantly better outcome than curettage and PMMA alone (HR: 1.07, p=0.881). Conclusion. Of all possible risk factors only soft tissue extension, localisation in radius and ulna and non-radical resections significantly influenced the risk of local recurrence for all treatments. In addition, we found that high-grade tumours and localisation in the axial skeleton were additional risk factors for local recurrence after intralesional surgery. Although wide resection increases patient morbidity, it can be the therapy of choice in high risk patients. Intralesional therapy can be advised for low recurrence risk patients using curettage and PMMA only, whereas our study could not confirm the predicted effect of phenol as an additional adjuvant

Patients with a history of venous thromboembolism (VTE) are considered at very high risk for recurrence after lower limb arthroplasty (LLA). However, the chance of a new VTE episode after LLA has not been yet quantified. The aim of this study was to define the incidence of VTE recurrence following knee and hip arthroplasty. The case notes for all LLA patients treated at our hospital from 2009 to 2011 were reviewed. There were 5946 primary and revision LLA operations in total; 118 of these interventions were performed in 106 patients with a history of VTE. This group included 69 females and 37 males with a mean age of 69.9. Routine thromboprophylaxis for LLA patients included mechanical (footpumps & TED stockings) plus chemical prophylaxis using Aspirin 150 mg for 6 weeks. Patients with a VTE history had the same mechanical prophylaxis but received warfarin for 3 months. There were no fatal VTEs within 90 days of surgery. There were 5 episodes (4.2%) of VTE recurrence and specifically 4 PE and one DVT (femoral vein) at 4 months after the operation. Two of the PEs were asymptomatic, diagnosed on CTPA scans being requested for low O2 saturations on routine monitoring. In the group of patients without a VTE history there were 35 VTE episodes (0.6%), indicating a significantly lower rate of VTE (p=0.001) in comparison with the study group. Patients with a history of VTE had a 4.2% chance of having a further VTE. This is seven times greater than the rate among all other patients despite using more aggressive chemoprophylaxis

Aims. The aim of the present study was to assess the outcomes of the induced membrane technique (IMT) for the management of infected segmental bone defects, and to analyze predictive factors associated with unfavourable outcomes. Methods. Between May 2012 and December 2020, 203 patients with infected segmental bone defects treated with the IMT were enrolled. The digital medical records of these patients were retrospectively analyzed. Factors associated with unfavourable outcomes were identified through logistic regression analysis. Results. Among the 203 enrolled patients, infection recurred in 27 patients (13.3%) after bone grafting. The union rate was 75.9% (154 patients) after second-stage surgery without additional procedures, and final union was achieved in 173 patients (85.2%) after second-stage surgery with or without additional procedures. The mean healing time was 9.3 months (3 to 37). Multivariate logistic regression analysis of 203 patients showed that the number (≥ two) of debridements (first stage) was an independent risk factor for infection recurrence and nonunion. Larger defect sizes were associated with higher odds of nonunion. After excluding 27 patients with infection recurrence, multivariate analysis of the remaining 176 patients suggested that intramedullary nail plus plate internal fixation, smoking, and an allograft-to-autograft ratio exceeding 1:3 adversely affected healing time. Conclusion. The IMT is an effective method to achieve infection eradication and union in the management of infected segmental bone defects. Our study identified several risk factors associated with unfavourable outcomes. Some of these factors are modifiable, and the risk of adverse outcomes can be reduced by adopting targeted interventions or strategies. Surgeons can fully inform patients with non-modifiable risk factors preoperatively, and may even use other methods for bone defect reconstruction.

Brachial plexus tumours (BPT) and peripheral nerve sheath tumours (PNST) are largely benign in nature, with malignant tumours being rare and presenting significant surgical challenges. Excision of benign tumours may relieve pain and other symptomology. This retrospective study analysed data from 138 PNST and 92 BPT patients managed by a single consultant orthopaedic or plastic surgeon experienced in nerve tumour surgery between January 1999 to December 2019. The most common benign tumours were schwannomas and neurofibromas, with sarcomas being the most common malignant tumour. In the PNST group 30 patients were managed by observation only. Twenty patients underwent trucut biopsy, 21 patients underwent biopsy and surgical excision and 56 patients underwent surgical excision only. There were nine complications, with two significant neurological deficits requiring further surgical intervention. No recurrence of tumours occurred in this group. In the BPT group 16 patients were managed by observation only. Seven patients underwent trucut biopsy, 16 patients biopsy and surgical excision and 44 BPT patients underwent surgical excision only. Sixteen patients had complications with two significant complications requiring urgent further surgical intervention. Seven patients had recurrence of tumours which presented as metastases, with three patients requiring further surgery to remove recurrence of tumours. BPT patients are more complex and present with both benign and malignant lesions and are therefore more prone to complications due to the complex nature of the surgery and higher recurrence rate of tumours than PNST. Benign tumours in both groups can be safely managed conservatively if patients’ symptomology is acceptable

Patellofemoral instability (PFI) is a common cause of knee pain and disability in the paediatric population. Patella alta, lateralised tibial tubercle, medial patellofemoral ligament (MPFL) deficiency, genu valgum and trochlear dysplasia are well known risk factors. A prospective database was created including patients referred through our physiotherapy pathway following first-time patella dislocation. Patella alta and lateralisation of the tibial tuberosity was treated with a Fulkerson-type tibial tubercle osteotomy(TTO). Medial patellofemoral ligament was reconstructed using quads tendon autograft pull-down technique. A modified Sheffield protocol was used postoperatively allowing weightbearing in a hinged knee brace. Forty patients were identified with 8 patients having bilateral presentations. Male to female ratio was 12:28 with an age range of 4–17 years. Eight patients had congenital PFI, five patients acquired PFI through traumatic patella dislocation and twenty-seven patients developed PFI from recurrent dislocations. Structural abnormalities were found in 38(95%) of patients. Patella alta (Caton-Deschamps index >1.2) was identified in 19(47%) patients, genu valgum in 12(30%) patients, increased tibial tubercle-trochlear groove distance(TT-TG>20mm) was present in 9(22.5%) patients and persistent femoral anteversion(> 20 deg) in 7(17%) patients. Eight patients were treated with TTO and MPFL reconstruction, three patients with MPFL reconstruction alone and five patients had guided growth for genu valgum correction. Ten patients are awaiting surgery. No postoperative patients had recurrence of PFI at their latest follow up. PFI is a common problem in the adolescent paediatric population with identifiable structural abnormalities. Correcting structural pathology with surgery leads to predictable and safe outcomes

Despite multiple published reviews, the optimum method of correction and stabilisation of Blount's disease remains controversial. The purpose of this study is to evaluate the clinical and radiological outcomes of acute correction of late-onset tibial vara by percutaneous proximal tibial osteotomy with circular external fixation using two simple rings. This technique was developed to minimise cost in a context of limited resources. This study was conducted between 2016 and 2020. We retrospectively reviewed the clinical notes and radiographs of 30 patients (32tibiae) who had correction of late-onset tibia by proximal tibial osteotomy and Ilizarov external fixator. All cases were followed up to 2 years. The mean proximal tibial angle was 65.7° (±7.8) preoperatively and 89.8° (±1.7) postoperatively. The mean mechanical axis deviation improved from 56.2 (±8.3) preoperatively to 2.8 (±1.6) mm postoperatively. The mean femoral-tibial shaft angle was changed from – 34.3° (±6.7) preoperatively to 5.7° (±2.8) after correction. Complications included overcorrection (9%) and pin tract infection (25%). At final follow up, all patients had full knee range of motion and normal function. All cases progressed to union and there were no cases of recurrence of deformity. This simple procedure provides secure fixation allowing early weight bearing and early return to function. It can be used in the context of health care systems with limited resources. It has a relatively low complication rate. Our results suggest that acute correction and simple circular frame fixation is an excellent treatment choice for cases of late-onset tibia vara, especially in severe deformities


Reconfiguration of elective orthopaedic surgery presents challenges and opportunities to develop outpatient pathways to reduce surgical waiting times. Dupuytren's disease (DD) is a benign progressive fibroproliferative disorder of the fascia in the hand, which can be disabling. Percutaneous-needle-fasciotomy (PNF) can be performed successfully in the outpatient clinic. The Aberdeen hand-service has over 10 years' experience running dedicated PNF clinics. NHS Grampian covers a vast area of Scotland receiving over 11749 referrals to the orthopaedic unit yearly. 250 patients undergone PNF in the outpatient department annually. 100 patients who underwent PNF in outpatients (Jan2019–Jan2020). 79M, 21F. Average age 66 years range (29–87). 95 patients were right hand dominant. DD risk factors: 6 patients were diabetic, 2 epileptic, 87 patients drank alcohol. 76 patients had a family history of DD. Disease severity, single digit 20 patients, one hand multiple digits in 15 patients, bilateral hands in 65 patients of which 5 suffered form ectopic manifestation suggestive of Dupuytren's diasthesis. Using Tubiana Total flexion deformity score pre and post fasciotomy. Type 1 total flexion deformity (TFD) between 0–45 degrees pre PNF n=60 post N= 85, Type 2 TFD 45–90 degrees pre PNF n=18 post N=9, Type 3 TFD 90–135 pre PNF n=15 post N= 5, Type 4 TFD >135 pre PNF n=1 post PNF N=1. Using Chi-square statistical test, a significant difference was found at the p<0.05 between the pre and post PNF TFD. Complication: 8 recurrence, 1 skin tear. No patients sustained digital nerve injury. Outpatients PNF clinics are a valuable resource

Aims

Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections.

Methods

Between January 2019 and December 2022, 106 patients with bone and joint infections were treated by five surgeons in five hospitals. Surgical debridement and calcium sulphate bead insertion was performed for local elution of antibiotics in high concentration. In all, 100 patients were available for follow-up at regular intervals. Choice of antibiotic was tailor made for each patient in consultation with microbiologist based on the organism grown on culture and the sensitivity. In majority of our cases, we used a combination of vancomycin and culture sensitive heat stable antibiotic after a thorough debridement of the site. Primary wound closure was achieved in 99 patients and a split skin graft closure was done in one patient. Mean follow-up was 20 months (12 to 30).

Aims

Fracture-related infections (FRIs) are a devastating complication of fracture management. However, the impact of FRIs on mental health remains understudied. The aim of this study was a longitudinal evaluation of patients’ psychological state, and expectations for recovery comparing patients with recurrent FRI to those with primary FRI.

Methods

A prospective longitudinal study was conducted at a level 1 trauma centre from January 2020 to December 2022. In total, 56 patients treated for FRI were enrolled. The ICD-10 symptom rating (ISR) and an expectation questionnaire were assessed at five timepoints: preoperatively, one month postoperatively, and at three, six, and 12 months.

Aims. The use of local antibiotic carriers in the treatment of chronic osteomyelitis is an important adjunct in dead space management. We present the outcomes of two different biodegradable antibiotic carriers used in the management of chronic osteomyelitis. Method. A single centre series between 2006–2017. The initial cohort (2006–2010) of 137 cases, Group A, had Osteoset® T (calcium sulphate carrier containing tobramycin). The second cohort (2013–1017) of 160 cases, group B, had CeramentTM G (biphasic calcium sulphate, nano-crystalline hydroxyapatite carrier containing gentamicin). Only Cierny-Mader Grade III and IV cases were included with a minimum six-month radiographic follow-up. Infection recurrence rate, wound leakage, subsequent fracture involving the treated segment, and radiographic void filling were assessed at a minimum of 6 months following surgery. Results. Mean follow-up in Group A was 2.5 yrs (0.5–10.5) and in Group B it was 1.4 yrs (0.6–4.7). Group A had a significantly higher rate of infection recurrence (16/137 (11.7%) Vs. 7/160 (4.4%) p=0.0278), wound leakage (26/137 (19.0%) Vs. 16/160 (10.0%) p=0.0304) and subsequent fracture rate (11/137 (8.0%) Vs. 3/160 (1.9%) p=0.0143) compared to Group B. Average time to recurrence was 1.07 years (0.1–2.6) in Group A and 1.02 (0.2–2.1) in Group B. The mean bone void healing in Group B was significantly better than Group A (73.2% Vs. 40.0%, p <0.00001). Conclusions. Cerament™ G has significantly better bone healing compared to a calcium sulphate carrier and was associated with a lower rate of recurrent infection, wound leakage and subsequent fracture risk

The modified Glasgow Prognostic Score (mGPS) is a validated prognostic indicator in various carcinomas as demonstrated by several meta-analyses. The mGPS includes pre-operative CRP and albumin values to calculate a score from 0–2 that correlates with overall outcome. Scores of 2 are associated with a poorer outcome. Our aim was to assess if the mGPS is reliable as a prognostic indicator for soft tissue sarcoma (STS) patients. All patients with a STS diagnosed during years 2010–2014 were identified using our prospectively collected MSK oncology database. We performed a retrospective case note review examining demographics, preoperative blood results and outcomes (no recurrence, local recurrence, metastatic disease and death). 94 patients were included. 56% were female and 53% were over 50 years. 91% of tumours were high grade (Trojani 2/3) and 73% were >5cm. 45 patients had an mGPS score of 0, 16 were mGPS 1 and 33 were mGPS 2. On univariate analysis, an mGPS of 0 or 2 was statically significant with regards to outcome (p=0.012 and p=0.005 respectively). We have demonstrated that pre-treatment mGPS is an important factor in predicting oncological outcome. A score of 0 relates to an improved prognosis whilst a score of 2 relates to an increased risk of developing metastases and death. mGPS as a prognostic indicator was not affected by either the tumour size or grade. We believe that a pre-operative mGPS should be calculated to help predict oncological outcome and in turn influence management. Further work is being undertaken with a larger cohort

Introduction. An aneurysmatic bone cyst (ABC) is a benign cystic lesion of bone composed of blood-filled spaces separated by connective septa. The most common treatment is curettage with or without bone grafting. Curettage with bone grafting and Ethibloc injection therapy have a comparable recurrence rate. Ethibloc is a radiopaque alcohol solution of corn protein which is percutaneously injected in the ABC. Objective. To compare percutaneous Ethibloc injection (ETHI) with curettage with bone grafting (CUBG) in the treatment of ABC. Methods. We conducted a retrospective cohort study of 73 treatments on 56 patients with ABC, between 1985 and 2007. The number of treatments were divided in two groups, one consisting of treatments with ETHI (n=35) and the other of treatments with CUBG (n=38). Both groups are comparable for the number of primary lesions; ETHI (n=17) and CUBG (n=21) or recurrences; ETHI (n=18) and CUBG (n=17). Radiological and clinical outcomes were assessed pre- and post-operatively. We evaluated the outcome measures of ETHI and of CUBG during a mean of 24.7 (range: 2–48) months. We evaluated the recurrence rate in both groups for a maximum period of 4 years to prevent the influence of outliers. Recurrence was defined as a radiological progression/recurrence of the lesion or progression/persistence of symptoms (pain, tumor, function impairment). Statistical analysis included a Kaplan Meier survival analysis, a cox-regression analysis to account for potential confounders and a chi-square test. Results. A survival analysis showed no difference in recurrence rate between both groups. A cox regression analysis showed that type of treatment, after correcting for size of tumor, location and previous treatment, had no influence on recurrence rate. There was no significant difference in clinical outcome in both groups; complete relief of all symptoms was found after ETHI and CUBG n=30 (86%) and n=33 (87%) respectively. Radiologically, 24 (69%) of the treatments with ETHI were effective (no recurrence) in 24 months (range: 3–48) and 28 (74%) of the treatments with CUBG in 23 months (range: 2–48). There was no significant difference between the ETHI vs. CUBG in the number of effective treatments in both primarily treated ABC's (10 vs. 15, p=0.3) as in ABC's with previous treatments (14 vs. 13, p=0.6). Complications after ETHI consisted of 2 fistulas and after CUBG of an AVN and failure of reconstruction. Discussion. This study shows that the relatively simple, percutaneous Ethibloc injection is comparable to curettage with bone grafting, regarding both clinical and radiological outcome. Recurrence rate was not influenced by type of treatment, location or size of tumour. We recommend Ethibloc injection as the first-choice treatment of primary and recurrent ABC's

Combined glenoid and humeral bone loss has been identified as an important factor in predicting recurrence after arthroscopic shoulder stabilisation. The “glenoid track” concept is proposed to predict recurrent instability by comparing the relative size of the glenoid to the humeral bone defect. The aim of this study was to investigate whether assessment of the glenoid track on a pre-operative MR arthrogram could be used to predict subsequent instability in a typical UK population. A retrospective study was undertaken of 175 primary arthroscopic stabilisation procedures of which 82% (n=143) were men. The median age was 26 years (IQR 22 to 32, range 16 to 77). The median follow-up was 76 months (range 21 to 125). A pre-operative MR arthrogram was used to determine if the shoulder was on-track or off-track. The endpoint of recurrent dislocation was examined. The prevalence of “off-track” bone loss in this group was 14.2% (n=25). There were 6 (24%) dislocations in the off-track group compared with 5 (3.33%) dislocations in the on-track group (RR 7.2, 95% CI 2.45 to 20.5, p=0.001). At 5 years, the cumulative redislocation rate was 26.1% in the off-track group compared with 8.7% in on-track group. The rate of any recurrent instability was 60% (n=15) v 18% (n=27) (RR 3.33, 95% CI 2.02 to 5.20, p<0.0001). Glenoid track (on v off) was not predicted by gender (p=0.411). In a typical UK population assessment of the glenoid track on an MR arthrogram can be used to risk stratify patients with shoulder instability

Introduction. Segmental bone defect is a challenging problem. We report our experience of bone transport by hexapod external fixator in patients with segmental defects if the tibia. Method. We report herein 15 patients with segmental bone defect of tibia who completed their treatment protocol. All patients were treated had bone transport with Taylor Spatial Frame from 2012 to 2017. All were treated by the senior author NH. Parameters measured included age, sex, diabetes, smoking, diagnosis, method of fixation prior to treatment use of a free flap, bone defect size, frame-time, external fixation index. Results. Mean age at the time of frame application was 42.7 years. Mean follow-up after frame removal was 23.7 months. Three were diabetic, one smoked and one quit smoking during treatment. Seven had Gustilo-Anderson 3B (47%) and 5 Gustilo-Anderson 3A (33%) open fractures. Three (20%) had closed fractures. Nine (60%) had internal fixation with plate in eight and IM nail in one. Ten patients (67%) had soft tissue defect that required a free flap in seven, local flap in two and skin graft in one. Mean transport was 62 mm. Mean external fixator time and latency were 350.1 and 12 days, respectively. Mean External fixator, distraction and maturation indices were 2.1, 0.52 and 1.43 month per centimeter, respectively. Ten Extra- procedures were required in 7 patients. There were no docking site procedures, non-union of regenerate, adjunctive stabilization after frame removal, recurrence of bone infection and recurrence of deformity. Conclusions. Segmental resection and transport by TSF is an effective method to achieve length, alignment and eradicate infection. Although our cohort had longer external fixator indices than similar studies, the complication rate was low

Background. The functional outcome and risk of recurrence following arthroscopic stabilisation for recurrent anterior shoulder instability is poorly defined in large prospective outcome studies. This is the first study to prospectively evaluate these outcomes in patients who have been treated using this technique. Methods. We performed a prospective study of a consecutive series of 302 patients (265 men and 37 women, mean age 26.4 years) who underwent 311 (9 bilateral) arthroscopic Bankart repairs for recurrent anterior instability. Patients were evaluated preoperatively and postoperatively at 6 months, and annually thereafter. The chief outcome measures were risk of recurrence and the two-year functional outcomes (assessed using the WOSI and DASH scores). Results. On survival analysis, the overall re-dislocation rate after surgery was 13.5% (42/311 shoulders). The median time to recurrence was 12 months (range 3 to 110 months) and 55% of these developed recurrent instability within 1 year of their surgery. The median follow-up in those patients who did not re-dislocate was 70 months. There was a significant improvement in the WOSI and DASH scores at 2 years postoperatively of 21.4 and 9.9 points respectively (both p<0.001). The risk of redislocation was significantly increased by the presence of glenoid bone loss associated with or without a Hill-Sachs lesion, and the type and engagement of a Hill-Sachs lesion on arthroscopic examination (all p<0.001). However, the risk in these sub-groups was lower than that reported in previous studies. A multivariate model was produced from these parameters to estimate the risk of recurrence at the time of primary surgery. Conclusions. The majority of patients have successful functional outcomes and relatively low risk of recurrence following arthroscopic stabilisation. The identification of preoperative factors which increase the risk of instability has enabled us to better counsel patients of their risk of failure following arthroscopic repair

Prosthetic joint infections provide complex management, due to often-difficult diagnosis, need for multiple surgeries and increased technical and financial requirements. “2 in 1” single stage approaches have been advocated due to reduction in risks, costs and complications. This study aimed to investigate the results of single stage revision using metaphyseal sleeves for infected primary Total Knee Replacement (TKR). Prospective data was collected on all patients presenting with an infected primary TKR over an 8-year period (2009–17). All revision procedures were undertaken in a single stage using metaphyseal sleeves. 26 patients were included, 2 of which had previously failed 2 stage revision and 3 failed DAIR procedures. Mean age was 72.5. Mean BMI was 33.4. Median ASA 2. Mean time to revision was 3.5 years range 3 months to 12 years. Six patients had actively discharging sinuses at the time of surgery. Only 4 of the 26 patients had no positive microbiological cultures from deep tissue samples or joint aspirates. Only one patient has a recurrence of infection. This patient did not require further surgery and is treated on long term antibiotic suppression and is systemically well. There were statistically significant improvements in both the pain and function component of AKSS scores. There was no significant improvement in flexion, however mean extension and total range of movement both showed statistically significant improvements. Using Metaphyseal sleeves in single stage revision for infected TKR are safe and lead to an improvement in pain, function and have excellent efficacy for eradication of infection

Aim. To analyse our results after en-block resection of aggressive GCT during 20 years period. Methods. We review 86 patients with skeletal GCT during the last 20 years, from 1990 until 2009, retrospectively. In the cases of latent and active type, extended curettage and bone graft or cement were our treatment of choice, while in aggressive ones we performed en block resection and reconstruction by fibular autograft (e.g. in distal part of radius) or fusion/hinge joint prosthesis (e.g. in GCT around the knee joint). We describe the recurrences, metastases and complications according to treatment. Results. There was no recurrence in 18 cases of en block resection and segmental bone defects were reconstructed with fibular autograft (5), joint fusion (4) and hinge joint arthroplasty (9). We had 2 cases of pulmonary metastasis that underwent resection of the metastasis. In one case, internal fixation failed and the graft broke; thus revision was performed. The rest 68 cases underwent extended curettage and bone graft (51) or cement (17). We had 7 cases of recurrence, 6 treated with repeated curettage and bone cement and one with en lock resection. No death or major complication was reported. Conclusions. In comparison of en block resection with extended curretage, the recurrence rate is greater with the latter; however it results in good control of the disease with less morbidity. In recent years, the invention of hinge knee prosthesis has increased the quality of patients' life in whom we could not preserve the involved joint

Heterotopic ossification (HO) of the hip after injury to the central nervous system can lead to joint ankylosis. Surgery is usually delayed to avoid recurrence, even if the functional status is affected. We report a consecutive series of patients with HO of the hip after injury to the central nervous system who required surgery in a single, specialised tertiary referral unit. As was usual practice, they all underwent CT to determine the location of the HO and to evaluate the density of the femoral head and articular surface. The outcome of surgery was correlated with the pre-, peri- and post-operative findings. In all, 183 hips (143 patients) were included of which 70 were ankylosed. A total of 25 peri-operative fractures of the femoral neck occurred, all of which arose in patients with ankylosed hips and were associated with intra-articular lesions in 18 and severe osteopenia of the femoral head in seven. All the intra-articular lesions were predicted by CT and strongly associated with post-operative complications. The loss of the range of movement before ankylosis is a more important factor than the maturity of the HO in deciding the timing of surgery. Early surgical intervention minimises the development of intra-articular pathology, osteoporosis and the resultant complications without increasing the risk of recurrence of HO

Objectives. Deep bone and joint infections (DBJI) are directly intertwined with health, demographic change towards an elderly population, and wellbeing. The elderly human population is more prone to acquire infections, and the consequences such as pain, reduced quality of life, morbidity, absence from work and premature retirement due to disability place significant burdens on already strained healthcare systems and societal budgets. DBJIs are less responsive to systemic antibiotics because of poor vascular perfusion in necrotic bone, large bone defects and persistent biofilm-based infection. Emerging bacterial resistance poses a major threat and new innovative treatment modalities are urgently needed to curb its current trajectory. Materials and Methods. We present a new biphasic ceramic bone substitute consisting of hydroxyapatite and calcium sulphate for local antibiotic delivery in combination with bone regeneration. Gentamicin release was measured in four setups: 1) in vitro elution in Ringer’s solution; 2) local elution in patients treated for trochanteric hip fractures or uncemented hip revisions; 3) local elution in patients treated with a bone tumour resection; and 4) local elution in patients treated surgically for chronic corticomedullary osteomyelitis. Results. The release pattern in vitro was comparable with the obtained release in the patient studies. No recurrence was detected in the osteomyelitis group at latest follow-up (minimum 1.5 years). Conclusions. This new biphasic bone substitute containing antibiotics provides safe prevention of bone infections in a range of clinical situations. The in vitro test method predicts the in vivo performance and makes it a reliable tool in the development of future antibiotic-eluting bone-regenerating materials. Cite this article: M.
