Background. Lisfranc/midfoot injuries are complex injuries with a reported incidence of 1 in 55000 in literature and frequently overlooked. But, recently they are becoming more commonly diagnosed with advent of CT scan and examination under anaesthesias (EUA) for suspicion fractures. Here we present a case series results of a single surgeons experience over the last 6 years. Methods. Retrospective review of 68 patients treated by a single surgeon over the last 6 years. Injuries were diagnosed on plain Xrays, clinic examination. Any suspicious injury were further assessed by a CT scan, all injuries were confirmed by EUA and treated with open reduction and internal fixation within 4 weeks of injury. Post-operative immobilisation in full cast for 6 weeks then a removal boot with non-weight bearing for a total of 3months. They were followed up regularly initially at 3, 6 and 12months. At final review the following data was collected: clinical examination, plain x-ray looking for: late deformity, signs of OA in Lisfranc joint, Auto fusion rate, rate of metal work failure. The x-rays findings were correlated with: (1) type of fixation. (2) The following scores: FAOS, AOFAS-M, specially designed new foot and ankle score. Results. 43 males: 25 females. 37 right: 31 left sided injuries. 90% were fully weight bearing with minimal discomfort after 6months. In 12 months all of them returned to their normal daily life activities. Wound complications: 2 of them had initial wound complications which were treated successfully with 2 weeks of oral antibiotics, 2 had lateral scar tenderness. One had loosened metal work, revised to fusion. Conclusion. Early operative intervention with good anatomical reduction can minimise the potential chronic disability associated with these injuries. This is a largest series of Lis-franc injuries of a single surgeon with good clinical outcome following surgical fixation

Background: Dislocation after total hip replacement (THR) is a significant concern with the increased number of THR carried out all over the world, although there has been a substantial lack of information regarding revision THR for instability in literature. Purpose: The purpose of this study was to evaluate the effectiveness of operative treatment for recurrent dislocation after THR. Material and methods: One hundred and eleven cases were treated operatively for recurrent dislocation after THR by a senior author (BMW). Group A; 104 cases were operated with change of either or both of components, a socket and a stem. Twenty-two mm head was used in 90 cases (A-1), 32 mm head in twelve (A-2), and 36 mm head in two (A-3). Group B; only modular head was changed in one case. Group C; augmentation device was applied on a cup in six cases. The average follow-up period was 6.2 years (range, 1 to 21 years). Results: Group A-1; twelve cases (13%) required further operations for instability (N=90). Group A-2; one case (8.3%) was converted to Girdle-Stone for recurrent dislocation (N=12). Group A-3; one of them was revised for periprosthetic fracture (N=2). Group B; the case survived at the follow-up of 3.3 years (N=1). Group C; two cases (33%) were revised for dislocation (N=6). Conclusion: We reported the largest series of revision THR for recurrent dislocation by a single surgeon with a considerable length of follow-up periods. Revision THR with change of components was an effective treatment for recurrent dislocation after THR

Introduction. Femoroacetabular impingement(FAI) is a relatively common cause causes of hip pain and dysfunction in active young adults. The concept of FAI was popularized by Ganz et al in early 2000s. Surgical treatment for FAI has been widely employed over the last two decades. The long term outcome of femoroacetabular osteoplasty (FAO) and risk factors for long-term failure of FAO is less studied. The goal of this single surgeon series is to identify the long term outcome of FAO (minimum 10-year follow-up) and risk factors for surgical treatment failure in these patients. Methods. The prospective database on hip joint preservation identified 1,120 patients who have undergone FAO between January 2005-June 2019. Of these 164 patients (178 hips) have a minimum 10-year follow-up (range, 10–14). The database collects detailed information on patient demographics, clinical history, radiographic and cross sectional imaging findings, intraoperative findings (site and size of chondral lesion, labral tear, subchondral cyst, size of cam lesion, etc), and patient outcome using the modified HHS, SF-36, and UCLA activity score. Patients are contacted on an annual basis and the functional outcome instruments administered. Of 1,120 patients, 122 patients have been lost to follow-up. Results. The mean age of patients in the cohort is 34.3±10.4 years and 39.6% of patients are female. FAO resulted in an improvement in mean mHHS (58.2±3.9 to 86.4±3.2) and SF-36(60.4±4 to 85±4.1) in 89% of patients. At the latest follow up 8.1% of patients have undergone THA. The study found that older age, longer preoperative symptomatic period, higher preoperative alpha angle, presence of hip dysplasia and acetabular retroversion, inability to repair acetabular labrum, and full thickness acetabular chondral lesion were associated with higher risk of failure of treatment. Conclusion. Patients with symptomatic FAI who undergo surgery experience pain relief and functional improvement that appears to endure over a decade in the majority. This study on a large cohort with long term follow-up has also identified patients who are at higher risk of failure. The study has also shed light on some interesting findings such as labral tear being very common in patients without hip symptoms and others that will be presented.

An independent audit of Lumbar Spinal surgery performed by a single surgeon over a 4 year period is presented. The three groups evaluated included Lumbar fusion, decompression and discectomy. Patients were assessed using the Oswestry Disability Questionairre and five other questions related to overall outcome and patient satisfaction. The minimum follow-up was 6 months. Patient response rate was 74%. The overall outcome was 81% Excellent/Good vs 19% Fair/Poor. The best outcomes were in the discectomy group. The decompression group showed a variable and unpredictable outcome. Complications encountered in the three subgroups are discussed. Lumbar spinal surgery offers lasting and predictable outcomes to a large majority of well selected patients. Independent surgical audits form an important part of evaluating one’s surgical practice

We retrospectively analysed a single surgeon series of 22 TER in 21 patients over a 12 year period. The mean age and follow up was 59.1 years and 64 months respectively. DASH scores assessed pre and post op confirmed a significant improvement. Complications included infection, intra-operative fracture, peri-prosthetic fracture and aseptic loosening. 6 revisions were performed for various reasons.4 patients had died due to unrelated causes. The 10 year survival rate with symptomatic aseptic loosening as the end point was 93%. 5 patients had radiological loosening but were clinically asymptomatic. TER is a rewarding procedure in with advanced RA

Introduction: Less invasive hip arthroplasty has been promoted since 2002 but with few reports having follow-up data. Existing information is often from developer-surgeons, selecting patients and investigating only the immediate post-operative course. More complete and less biased information is needed. Methods: This prospective series, 275 hips done consecutively beginning April 2003, by a single surgeon using the direct anterior approach first described by Robert Judet, is entirely unselected: 31% obese, 16% over 80, but 22% Charnley category A. Follow-up is at least 2 years. Standardized hip scores and radiographic measurements were obtained regularly. Result: Nine re-operations (3.5%) were required: 2 infections (0.8%), 6 component failures (2%) and 2 superficial wound infections (1%). There were 3 dislocations (1.2%). Charnley Merle d’Aubigne, WOMAC and Harris Hip Scores improved significantly (p=0.001 for each) and component positioning was reproducible. Over 80% of these patients were discharged directly home after an average length of stay 2.2 days. Walking without assistance averaged 4 weeks; return to work 6 weeks. Surgical time and hospital stay decreased significantly during the time of study (p = 0.001 for each). Discussion: Given the excellent result from conventional hip arthroplasty, a change in technique might, at best, slightly benefit most patients at the risk of greatly harming a few. This report suggests that the single incision direct anterior approach is applicable to all THA patients, early recovery is acceptable, and a reasonable learning curve exists; but early complications may be increased when compared to the best experience using traditional approaches

TER is a viable surgical option in patients with advanced RA with painful stiff elbows. We retrospectively analysed 22 TER performed in 21 patients over a 12 year period by a single surgeon, with a mean follow up of 64 months (10–145). Disability of the arm, shoulder and hand (DASH) scores were performed pre-operatively and post-operatively in patients through postal questionnaires. The mean age was 59.1 years (32–78). There were 12 women and 9 men. The mean pre-operative DASH score was 72.3 (45.0–91.7) and post-operatively improved to 46.8 (21.7–94.2). Complications included infection, peri-operative fracture, peri-prosthetic fracture and aseptic loosening. There were 6 revisions performed, 2 for peri-prosthetic fracture, 2 for infection, 1 for intra-operative fracture and 1 for symptomatic aseptic loosening. Four patients had died due to unrelated causes. The 10 year survival rate with symptomatic aseptic loosening as the end point was 93% and revisions for all reasons was 69%. Follow up radiographs (in those without revision) were reviewed and 10 had satisfactory positioning of the prosthesis, 5 had loosening of the humeral or radial component and 1 had inadequate cement mantle but was clinically asymptomatic. TER is a rewarding procedure in with advanced RA. Our results are comparable to other published studies

PURPOSE. To report the experience and evolution of treatment of Congenital Pseudarthrosis of the Tibia in a single surgeon, consecutive series of 19 patients. METHODS. A retrospective case series review, with radiological assessment and functional outcome scores including the Activity Scale for Kids (ASK) and the Oxford Ankle Foot Questionnaire (OAFQ) Child & Teenager version. Patients were classified as per Boyd & Andersen. Alteration in the Tibial mechanical axis was compared pre-treatment and at last review. RESULTS. The average follow up from presentation was 6.3 years, 7 patients had reached skeletal maturity. Union was obtained in 79% at the time of review with a mean time to union of an established pseudarthrosis of 15.2 months. 9 of 19 had an established diagnosis of Neurofibromatosis. 8 had a frank pseudarthrosis at presentation, 2 of which were present at birth. There were 3 re-fractures following treatment. One of the 19 required amputation after failed surgical treatment. Each patient had an average of 2.4 surgical procedures. 14 patients had either fixed or elongating rods, 10 had Ilizarov treatment. 2 have outstanding surgery planned. CONCLUSIONS. A philosophy of treatment has evolved which produces acceptable results. Splintage is used for antero-lateral bowing with corrective osteotomies and rodding, without extensive bone or periosteal resection, for significant or progressive deformity or fracture. Ilizarov treatment is used for recalcitrant cases over the age of 6 years. The technique has evolved over time to include bone graft wraps and the use of Bone Morphogenic protein in combination with the Ilizarov technique. Patients have below population and age matched average scores for both the ASK and OAFQ

Simultaneous bilateral Total Knee Arthroplasty (TKA) has been reported to bring greater patient satisfaction, reduce in-patient stay and recovery, with similar outcomes to single sided or staged TKA, but higher complication rates. No validated selection criteria exist. We report the results of a single surgeon's experience of simultaneous bilateral TKA, using set guidelines for patient selection. A prospectively maintained database of all simultaneous bilateral TKA performed between 2002 and 2008 was retrospectively analysed, supplemented by case-note review. Outcome measures included length of stay, blood loss and transfusion rates, complications and functionality and validated outcome scores. 40 patients were included, 23 male and 17 female, all with osteoarthritis. Mean age was male 64.9 and female 61.3 years. Mean ASA grade was 1.8. All fitted selection criteria. Mean tourniquet time was right 79.1 minutes and left 83.6 minutes. Preoperative mean haemoglobin level was 141.8 g/dl and mean post operative level of 87.3 g/dl. 13 patients received purely autologous blood transfusion, 16 patients purely allogenic and 6 patients received both. There was 1 intraoperative complication (Medial collateral injury), 3 minor post operative complications which recovered prior to discharge. There were no thromboembolic events or deaths. Mean follow-up was 32.7 months (range 3-79 months). Mean in-patient stay was 7.5 days. Mean range of movement at most recent follow up was right 1.0 to 119.1 degrees flexion and left 1.0 to 120.8 degrees flexion. Mean Knee Society Scores pre- versus post-operatively were: 67 knee/62 function versus 90 knee/82 function. Oxford Knee Scores, Pre- versus post-operatively were: 43 versus 35 (Scoring 0-60, lowest best outcome). We demonstrate that with appropriate selection criteria, simultaneous bilateral TKA is safe and successful, giving excellent functional outcomes

Aim:. Audit of the outcome of subcapital osteotomy for a series of cases of severe unstable slipped capital femoral epiphysis. Method:. 57 cases of unstable severe slipped capital femoral epiphysis were operated on by a single surgeon between 2000 and 2011. The procedure was performed through the anterior abductor sparing approach. Patients have been followed up prospectively and the results are presented at average follow up is 6.4 years with a minimum of 18 month follow to include all risks of avn. Results:. There were 35 males (average age 13.85 years) and 22 females (average age 12.4 years). Three syndromic cases, 2 Trisomy 21 (with no avn) and one pituitary/corpus callosum agenesis (developed avn) were included. 5 patients (8.7%) developed avn, one syndromic, another with noted avn on pre-operative MRI and the third with partially healed growth plate. Excluding these patients the avn rate was 2/54 (3.7%). Re-operations were performed on the avn group including two head neck debridements and valgus osteotomy, one head neck debridement alone and one arthrodesis. One patient is awaiting debridement and valgus osteotomy. One patient developed chondrolysis and has had no intervention 6 years. 2 patients developed asymptomatic heterotopic bone ossification and the incidence of lateral cutaneous nerve symptoms was 35% none requiring intervention. Leg length difference was less than 1 cm in those patients who did not develop avn. Conclusion:. This single surgeon audit shows lower risk of avn than and strengthens the argument for referral to specific centres for such conditions. Level of evidence: IV

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. We present a single surgeon series of 20 modified Dunn osteotomies without surgical dislocation of the femoral head for slipped upper femoral epiphysis (SUFE). Method. All patients from 2007 to 2011 who had a Dunn osteotomy for SUFE had their notes reviewed and we obtained an updated Non Arthritic Hip Score. Results. 20 patients were identified, of which 5 were female, with a combined average age of 14. The average duration of symptoms prior to the procedure was 10.2 weeks (range, 4–78). Classifications divided the cases into 7 chronic slips, 7 acute-on-chronic, and 5 acute., and 7 of the cases were unstable slips with an average slip angle of 71 degrees (range 65–85). All slips were grade 3. Average follow up was 26.2 months (range, 2–62). 3 developed avasular necrosis (2 unstable, 1 stable) and 2 patients had symptomatic leg length discrepancy. Preoperative MRI scans were performed in 4 patients and showed vascular compromise, but this did not always correlate with intraoperative findings of avascularity when the head was drilled. The average Nonarthritic hip score was 71.6 (range, 60–80). Summary. Dunn osteotomies are safe in patients with chronic slips, and have a low incidence of AVN. Overall function was good, even in those patients with segmental AVN scoring highly on their hip scores. Keeping the ligamentum teres intact and not dislocating the femoral head may improve vascularity of the head. Vascularity may also be assessed by preoperative MRI scans, although radiological suggestion of an avascular head which contradicted clinical findings and postoperative outcome may be due to transient vessel spasm

The aim of the paper is to provide an independent single surgeon experience with BHR after a seven-year follow-up. A cohort of 117 hips in 101 consecutive patients operated by the senior author between Jan 1998 and Dec 2002 were assessed to note their clinical, radiological and functional outcome after a mean follow-up of 7 years (5–9.4 years). Primary osteoarthritis was seen in 73 hips and secondary in 44 hips. Their mean age at surgery was 54 years (range 20–74years). At latest follow-up their mean flexion was 100°and their mean functional outcome scores were respectively: Oxford hip score of 21.5 (12–52, mode 12); Harris hip score of 84.8 (25–100, mode 97), Charnley modification of Merle d’ Aubigné and Postel scores were 4.8 for pain, 4.3 for walking and 5.4 for movement; and SF-36 (physical component 43.9 and mental component 51.45). Failure in the study was defined as revision for any reason. Revision was undertaken in 8 hips (6.8%), five within the first year for periprosthetic fracture neck of femur and 3 hips after the end of 5-year follow-up (2 for advance collapse of the femoral component in patients’ with avascular necrosis of the femoral head and 1 hip for sepsis). The Kaplan-Meier survival with revision as end point at minimum 5-years of follow-up was 95.7% (95% CI 92–99%) and overall survival at an average 7-years was 91.7% (95% CI 86–97.6%). All the failures were due to the femoral component. However, the reported survival with the use of traditional uncemented and cemented femoral stems is beyond 99% at similar period of follow-up. Patient selection particularly in patients with secondary osteoarthritis is therefore a critical factor when choosing BHR components

Clinical success of total knee arthroplasty is correlated with correct orientation of the components. Controversy remains in the orthopaedic community as to whether the intramedullary or extramedullary tibial alignment guide is more accurate in the tibial cut. Is there any difference between intramedullary and extramedullary jigs to achieve better accuracy of the tibial components in total knee replacements?. A retrospective study done on 100 patients during the time period 2007 to 2010. The 100 knee replacements were done by the same surgeon, where 50 patients had the intramedullary tibial alignment guide and the other 50 had the extramedullary one. The tibiofemoral angle was measured pre-operatively as well as post operatively, the tibial alignment angle was measured post operatively then the results were statistically analysed using the SPSS. There was no significant difference between both groups regarding the tibial alignment angles. Both techniques proved accurate in producing an acceptable post operative tibial component alignment angle. We recommend orthopaedic surgeons choose either technique knowing that accuracy levels are similar. The debate between intramedullary and extramedullary tibial cutting jigs/guides/ devices continues and most orthopaedic surgeons will use their preferred technique and will continue to achieve good post operative results as we have found in our centre. Our study is rare due to the fact we have a single surgeon performing both techniques, therefore controlling for any surgical experience or operating technique differences

Introduction: Percutaneous epiphysiodesis is a well established procedure in the treatment of leg length discrepancy. Many techniques have been described ranging from an open technique to the more recently described percutaneous technique. This study assesses the percutaneous single portal technique, in combined distal femoral and proximal tibial lower limb epiphysiodesis, performed by a single surgeon. Methods: We performed a retrospective review of cases performed in a single institution by a single surgeon from 1994 to present. A total of 45 combined epiphysiodesis were performed. 40 patients qualified for the study group with at least 2 years follow up. There were 19 female and 21 male patients, with the operative side equally shared between left and right. Results: The mean predicted leg length discrepancy using the Mosley Straight Line Graph was 2.43 cm. The mean final leg length discrepancy, at an average follow up of 31 months, was 1.5 cm with a range of 0 to 2.81 cm. There were no angular deformities at follow up. One female patient had a knee effusion which resolved spontaneously. One male patient complained of anterior knee pain initially post surgery however this resolved at final follow up without treatment. The majority of patients (n=34) were inpatients, however more recently this procedure has been successfully carried out as a day case (n=6). Discussion: Percutaneous epiphysiodesis has been accepted as a standard technique to treat leg length discrepancy of 2 cm to 5 cm. Several techniques have been described in the literature with varying complication rates. This study shows that single portal combined epiphysiodesis is successful and has a relatively low complication rate

Introduction: REEF™ is a modular distal locking implant, indicated for use in extensive loosening of femoral stems, peri-prosthetic hip fractures, and tumour surgery requiring distal anchorage to allow resection of the femur proximally. Very little experience with the REEF™ has been reported. Objective: We report on a single surgeon series of 16 patients who underwent femoral reconstruction using the REEF™ during revision hip arthroplasty (THA). Methods and Results: This is a retrospective analysis of prospectively collected data on 16 patients (14 females) who underwent revision THA using the REEF™, between 1998 to 2007with a mean follow-up of 16 months (range, 3 to 60). Indications were peri-prosthetic fractures in 9 cases (Vancouver B1 in one case, B2 in 4 cases and B3 in 4), aseptic loosening with significant bone loss in 3 (Paprosky IIIA in one case, Paprosky IIB in one and Type IV in one), osteolysis (Paprosky IV) secondary to infection in 1, non-union of peri-prosthetic fracture in 2 (Vancouver B2 and B3) and fracture around a spacer in one case. The mean HHS at 3 months post-operatively was 72 (range, 57 to 76). The median pre-operative/pre-injury University of California, Los Angeles hip rating system (UCLA) was 1. The median UCLA at longest follow-up was 3.5 (range, 1 to 4) with 10 patients having a score greater than 3. Mean time to clinical evidence of implant integration was 4 months (range, 2 to 12). No evidence of subsidence was noted. Four dislocations were seen. No dislocation was seen in the 6 patients who had a Posterior Lip Augmentation Device (PLAD™) inserted at the time of revision THA. One stem fracture occurred requiring revision surgery with a longer REEF™ implant. Two patients died in the immediate post-operative period. Conclusion: Results of revision THA using the REEF™ implant are encouraging. We recommend the use of the REEF™ with the judicious use of PLAD™ in difficult revision THA

Purpose: To present results of a series of patients treated with Trapeziectomy, Ligament Reconstruction and Tendon Interposition for treatment of 1st CMC joint arthritis. Methods: 59 patients (65 thumbs) from Single surgeons’ practice were prospectively followed by 2 independent observers who did not participate in the study. Patient demographics, occupation, handedness, symptoms and clinical findings were recorded. Objective assessment including pinch and grip strength was carried out by the Occupational therapists. Functional outcome assessment was done using questionnaire designed by senior author. Patients were asked to evaluate the operation using the subjective assessment component of Buck-Gramcko score. Radiographs were studied for Trapezial space and arthroplasty space. Analysis was carried out using SPSS statistical software. Results: A total of 59 patients at an average age of 62 years were followed up for an average of 25 months. Six patients had bilateral procedures. Average follow up was 3.5 years with minimum follow up being 3 years. Osteoarthritis was the commonest diagnosis accounting for 53 (91%) patients and rheumatoid arthritis in 6 (9%) of patients. 48 cases (82%) were Stage IV and 15 cases (18%) Stage V. Mean duration of symptomsbefore the surgical intervention was 36 months. 3 patients developed superficial wound infection and 4 patients developed reflex sympathetic dystrophy. The results suggested pinch strength and grip strength improved to 50% and 22.5% respectively, as compared to pre-operative value. Conclusion: Treatment options for 1st CMC joint arthritis have evolved over time. Many prospective randomized studies have shown lack of advantage of LRTI as compared to trapeziectomy alone, but these studies are not free from limitations. The present study is one of the largest reported single surgeon series and benefits from aprospectively maintained database with minimum 3 years follow up. The study rises above the existing limitations in the literature and reinforces concept of Ligament Reconstruction and Tendon Interposition. Level of Evidence: Level II (Prospective study)

Aim: We present the outcome of Birmingham Hip Resurfacing Arthroplasty performed by a single surgeon after at least five years follow up. Patients and Methods: One hundred hips in 84 patients were studied with a mean follow-up of 6.4 years (5–8.3 years), performed by a single surgeon. Three patients died of unrelated causes and 2 patients were lost to follow-up, hence the study group comprised of 79 patients with 95 hips. Birmingham resurfacing femoral and acetabular components were used in all patients. The clinical outcome was measured using Harris, Charnley, Oxford hip scores and quality of life using SF-36. Radiographs were systematically analysed for implant position, fixation, and loosening. Results: The mean age was 54 years (20–74years) and BMI of 28 (19–35). Primary osteoarthritis was seen in 69 hips. Six patients (6.1%) underwent revision of the femoral component (3 for peri-prosthetic fractures of the neck of femur, 2 for deep infection and 1 for collapse due to AVN). None of the patients had evidence of loosening around the acetabular component and femoral components in 28 patients. Type 1 pedestal sign was seen in 61 hips and Type 2 in 2 hips. The clinical scores were respectively, Harris 85 (25–100), Oxford 21.5 (12–52), mean Charnley score 4.8 for pain, 5.3 for movement and 4.3 for mobility; the mean SF-36 score were 44 (12–58) for the physical and 51.4 (19–71) for the mental component. With an end point of definite or probable aseptic loosening, the probability of survival at 5 years was 100% and 97.3% (95% CI = 2.9) for acetabular and femoral components respectively. Overall survival at 5years with removal or repeat revision of either component for any reason as the end point was 91% (95% CI: 82 to 97%). Conclusion: The results of this study support the continued use of Birmingham Hip Resurfacing Arthroplasty in young active individuals. As loosening can occur as a late phenomenon, a longer follow up is needed to determine longevity, durability of this prosthesis

Introduction: The Taylor spatial frame (TSF) (Smith & Nephew) is a hexapod ring fixator that utilises the Ilizarov principles. The TSFs design is based on the Stewart-Gough platform, the use of which was originally described in mechanical engineering. Due to its unique design the TSF is extremely versatile in limb reconstruction surgery, allowing six degrees of freedom bone fragment manipulation with a high degree of precision that is aided by correction planning software. Methods: Between October 2003 and December 2008 66 consecutive patients were treated using the TSF by a single consultant surgeon. Median patient age was 45 (range 20–69). The original pathology included 18 mal-unions, 13 acute fractures, 10 medial compartment osteoarthritis (OA) of the knee with varus deformity, 8 infected nonunions, 7 limb length discrepancies, 5 nonunions, 3 ankle OA, 3 post traumatic posterolateral corner of the knee instability, 1 multiple epiphyseal dysplasia, 1 lateral compartment OA of the knee with valgus deformity, 1 deformity secondary to Polio. There were 10 ankles, 19 knees (1 femur, 18 tibiae) and 37 tibiae. Results: The procedures performed were 16 high tibial osteotomies, 2 frame assisted platings, 8 bone transports, 32 deformity corrections, 14 Ankle arthrodesis (9 primary, 5 revision after nonunion), 9 limb lengthening and 1 derotation. The median bone transport distance and lengthening achieved is reported. The median time spent in the frame was 21 weeks (range 9–81), including 8 patients who required 2 frames to complete their treatment. 54 cases had a satisfactory outcome in terms of union and deformity correction using only the TSF, 5 cases were ongoing. Complications included 1 below knee amputation, 2 docking site nonunions requiring ORIF, 2 nonunions after ankle arthrodesis requiring T2 nails. 2 frames were removed due to compliance issues. 2 patients developed deformity requiring Tendo-achilles lengthening. There were 2 DVTs and 2 non-fatal PEs. 1 patient suffered a fracture at a femoral pin-site after TSF removal which was treated with external fixation. The median Otterburn grade of pin-site infection was 2 (range 0–4). Conclusion: The Taylor spatial frame was used successfully in several different pathologies ranging from acute trauma to chronic deformity. The TSF provides the surgeon with a reliable treatment strategy that is both versatile and accurate

Introduction: Revision hip arthroplasty places a significant burden on hospital resources. Huge pressure is being placed on the orthopaedic community to alter practices with respect to implant selection and bearing surfaces in order to try to reduce the likelihood of revision due to aseptic socket loosening. To date there is little clinical evidence to support these changes. Aim: To review the case mix requiring revision surgery at a specialist arthroplasty unit in order to identify the common reasons for failure of primary arthroplasties. Methods: A retrospective single surgeon review was performed to identify patients who had undergone revision hip surgery over the study period. The reasons for revision were identified for all cases. Particular attention was paid to the cases with aseptic socket loosening to determine the time to revision for these cases. Results: 176 revision procedures were performed between October 2001 and May 2005. In 74 (42%) cases aseptic socket loosening was identified (average socket survival 15.4 years). In 16 cases this was the sole cause for revision. In 58 cases the femoral component was also loose. 102 (58%) cases were performed for other reasons. Dislocation was the cause in 14%, femoral component loosening in 20%, infection in 18% and fracture in 6%. Aseptic loosening of cemented sockets less than 10 years old was only seen in 7 (4%) cases. Conclusions: Aseptic loosening of cemented sockets less than 10 years old was the least common cause of revision in this series. Cemented polyethylene acetabular components continue to provide a satisfactory bearing surface on the acetabular side of total hip arthroplasties. We recommend caution when interpreting the information provided with new products with respect to the benefits of different fixation and bearing surfaces for the majority of patients
