Introduction. Unicompartmental knee arthroplasty (UKA) is becoming an increasingly popular option in single compartment osteoarthritis. As a result, diverse re-operations including revisions to total knee arthroplasty (TKA) has also increase. The objective of this study is to investigate the distribution of causes of re-operations after UKA and to analyze the types of re-operations. Method. We retrospectively reviewed 691 UKAs performed on 595 patients between January 2003 and December 2011. Except in one case, all UKAs were performed for medial compartment osteoarthritis of the knee. The UKAs were performed in 487 (81.8%) women and 108 (18.2%) men. The mean age at the time of UKA was 61.5 years (47 to 88 years). Mobile-bearing designs were implanted in 627 (90.7%) knees (626- Oxford knee and 1- Scorpio knee) and fixed designs were implanted in 64 (9.3%) knees (42- Tornier and 18- Zimmer). The mean interval between UKA and second operation was 15.4 months (10 days to 10 years) and between second and third operation was 7.7 months (5 weeks to 17 months). In the

There has been recent interest in the treatment of Dupuytren's disease by minimally invasive techniques such as needle fasciotomy and collagenase injection, but only few studies have reported the outcomes following open fasciotomy. This study attempts to address this gap, with a retrospective analysis of a large series of patients who underwent an open fasciotomy by a single surgeon over a five-year period. The aim of the study was to determine the requirement for

To describe complications and reoperation rates associated with degenerative spinal deformity surgery. A retrospective review of prospectively collected data from a single spinal surgeon in the United Kingdom. A total of 107 patients who underwent surgery, of 5 or more levels, for primary degenerative kyphoscoliosis between 2006 and 2012 were identified. Clinical notes were reviewed and post-operative complications, reoperation rates, length of follow up and mortality were analysed. A total of 107 patients, average aged 66.5 years (range 52 – 85), with 80% women. 105 patients underwent posterior surgery, two patients required both anterior and posterior surgery. The average number of instrumented levels was 8.3; 10% 5 levels, 15% 6 levels, 11% 7 levels, 14% 8 levels, 15% 9 levels and 35% had fusions of 10 levels and above. 58% included fixation to sacrum or pelvis. 93% had a decompression performed and 30% had an osteotomy. There were 40 complications recorded within the follow-up period. Infection occurred in 7 patients (6.5%). All were successfully managed with debridement, antibiotic therapy and retention of implants. There were 4 dural tears (3.7%). One patient developed a post-operative DVT (0.9%). No patients sustained cord level deficits. Prevalence of mechanical complications requiring
Following introduction of the second offer scheme in April 2004, Cardiff and Vale NHS Trust sent 227 patients (254 knees) to the independent sector treatment centre in Weston-Super-Mare for total knee arthroplasty. The Kinemax total knee system was used in all cases. There was a perception that there were a large number of dissatisfied patients, and a previous British Orthopaedic Association report (of a 14 case sample) questioned the quality of the surgery performed. All of the patients concerned were offered a review in order to assess the outcome. Of the 227 patients (254 knees), 77% have been reviewed (167 patients, 190 knees). 23% (59 patients, 64 Knees) have not been seen. Of these, 30 patients (34 knees) declined review on the basis that they were happy with the result of surgery. 14 Patients (15 knees) were unobtainable by post of by phone. A further 12 patients (12 knees) did not attend appointments. 3 Patients (3 Knees) had died. The total number of re-operations was 27/254, giving a
Introduction:. Mayo 2A Olecranon fractures are traditionally managed with a tension band wire device (TBW) but locking plates may also be used to treat these injuries. Objectives:. To compare clinical outcomes and treatment cost between TBW and locking plate fixation in Mayo 2A fractures. Methods:. All olecranon fractures admitted 2008–2013 were identified (n=129). Patient notes and radiographs were studied. Outcomes were recorded with the QuickDASH (Disabilies of Arm, Shoulder and Hand) score. Incidence of infection, hardware irritation, non-union, fixation failure and
To assess whether Patients who are clinically Obese are more likely to require further or revision Surgery following One-Level simple Microdiscectomy compared to Non-obese Patients. Retrospective, single centre and single Surgeon review of Patients' Clinical notes of consecutive Patients who underwent primary One-Level Microdiscectomy between December 2007 and July 2009. Background: Obesity in Surgery has become a topical subject given the increasing proportion of Surgical Patients being Obese. This study provides the largest single centre and single Surgeon comparative cohort. All Patients had undergone One-level simple Primary Microdiscectomy Surgery. Data from the Clinical notes included Patient Demographics, level and side of operation, Length of stay and
The Profix knee replacement arthroplasty manufactured by Smith and Nephew has been in use for the past five years however there are few published outcome data for this prosthesis. The purpose of this study was to provide clinical outcome data for a cohort of patients with a Profix TKR at a minimum 3 years follow up. There were 65 joint replacements in 58 patients all performed by or under the direct supervision of one of two senior consultant Orthopaedic surgeons. There were 34 right and 31 left knees replaced in 31 male and 27 female patients. Mean age of the patients was 69 years (51–84 years) and mean body mass 89Kg (45–140Kg). The femoral component was uncemented in 49 knees and cemented in 16 knees. The tibial component was cemented in all 65 cases. There were 53 mobile bearing polyethylene inserts and 12 fixed bearing knees. The patella was resurfaced primarily in 32 cases. Using the Oxford Knee score, the mean knee score was 20.7 (Range 12–42) where a perfect score is 12 and the worst possible score 60. Mean clinical range of movement was 111 degrees (Range 90–130 degrees). Of the 65 joints, 13 have required or are awaiting some form of
Introduction: We derived an exhaustive operative and supervision guideline for the treatment of hip fractures from the current international and own published literature, and implemented the guidelines in our department. Methods: 1274 unselected consecutive patients admitted with a hip fracture were included, 336 of these prospectively after implementation of the new guideline. Demographic parameters, hospital treatment and re-operations were assessed from patient journals. Re-operations were recorded after six months. Results: 95% (320/336) of operative procedures were found to have followed the new guideline treatment compared to 78% (733/938) prior to its introduction (p<
0.001 X2). Retrospectively we found that only 12% (121/1053) of operative procedures performed as the new guideline prescribes were re-operated compared to 24% (53/221) of operative procedures performed with other methods (p<
0.001 X2). In logistic regression analysis combining sex, age, ASA score, cognitive function, new mobility score, time from admission to operation and level of surgeon’s experience, not following the guideline was the only significant predictor for
Reoperations may be a better way of tracking adverse outcomes than complications. Repeat surgery causes cost to the system, and often indicate failure of the primary procedure resulting in the patient not achieving the expected improvement in pain and function. Understanding the cause of repeat surgery at the primary site may result in design improvements to implants or improvements to fusion techniques resulting in better outcomes in the future. The COFAS group have designed a reoperation classification system. The purpose of this study was to outline the inter and intra observer reliability of this classification scheme. To verify the inter- and intra-observer reliability of this new coding system, six fellow ship trained practicing foot and ankle Orthopaedic surgeons were asked to classify 62 repeat surgeries from a single surgeons practice. The six surgeons read the operation reports in random order, and reread the reports 2 weeks later in a different order. Reliability was determined using intraclass correlation coefficients (ICC) and proportions of agreement. The agreement between pairs of readings (915 for inter observer for the first and second read – 61 readings with 15 comparisons, observer 1 with observer 2, observer 1 with observer 3, etc) was determined by seeing how often each observer agreed. This was repeated for the 366 ratings for intra observer readings (61 times 6). The inter-observer reliability on the first read had a mean intra-class correlation coefficient (ICC) of 0.89. The range for the 15 comparisons was 0.81 to 1.0. Amongst all 1830 paired codings between two observers, 1605 (88%) were in agreement. Across the 61 cases, 45 (74%) were given the same code by all six observers. However, the difference when present was larger with more observers not agreeing. The inter-observer reliability test on the second read had a mean ICC of 0.94, with a range of 0.90. There were 43 (72%) observations that were the same across all six observers. Of all pairs (915 in total) there was agreement in 804 pairs for the first reading (88%) and disagreement in 111 (12%). For the second reading there was agreement in 801 pairs (86%) and disagreement in 114 (14%). The intra-observer reliability averaged an ICC value of 0.92, with a range of 0.86 to 0.98. The observers agreed with their own previous observations 324 times out of 366 paired readings (89% agreement of pairs). The COFAS classification of reoperations for end stage ankle arthritis was reliable. This scheme potentially could be applied to other areas of Orthopaedic surgery and should replace the Claiden Dindo modifications that do not accurately reflect Orthopaedic outcomes. As complications are hard to define and lack consistent terminology reoperations and resource utilisation (extra clinic visits, extra days in hospital and extra hours of surgery) may be more reliable measures of the negative effects of surgery.
Aim: Volar locking plates are increasingly used in the management of distal radius fractures. As with any new implant, understanding the rate and type of potential metalwork related complications is important. The aim of the study was to determine the type and rate of implant related complications that require further surgery when using volar locking plates in the management of distal radius fractures. Methods: In this study, we reviewed 114 distal radius fractures treated with volar locking plating. Patient records were reviewed with regards to demographics, operative details and post-operative outcomes. Fractures were classified as intra-articular or extra-articular. They were further classified using the AO classification system. Results: In our series, 12 cases (10%) underwent further surgery for metal work related complications mainly for screw protrusion into the radiocarpal joint following fracture collapse. Intra-articular fractures had a significantly greater complication rate as compared to extra-articular ones (11 vs. 1, P=0.04). There was no significant difference between the three plating systems used in this series with regards to need of further surgery (P=0.43). There was no significant difference between the grade of the operating surgeon with regards to metal work complications (P=0.9). There was no difference in rate of complications between males and females (P=0.27). Similarly there was no difference in metal work complications between patients aged less than 60 as compared to those aged more than 60 years (P=0.58). Our study has shown that volar locking plates may be associated with up to 10% rate of metalwork complications requiring revision surgery. The most common (8 out of 12) cause of
Osteolysis is one of a major cause of failure that affect long term survival rate in THA. Hard-on-hard bearing surface were developed to reduce wear and osteolysis, such as ceramic-on-ceramic which is the lowest wear rate was introduced but it still has squeaking and ceramic fracture. Metal-on-metal bearing surface significantly reduce wear rate but it still release metal ion which affect local tissue reaction. Then ceramic-on-metal is another choice of bearing with combine the advantage of reduce wear rate, metal ion release, no stripe wear, no squeaking and no ceramic fracture. However after clinical use ALTRs may occur and disturb the longevity of THA. During January 2009 to December 2009 we performed 98 THR with the same femoral stem and acetabular cup with difference bearing which were 87 cases of metal on cross-linked PE, 8 cases of ceramic on metal and 5 cases of metal on metal. Routinely postoperative care were done with clinical evaluation, plain x-rays and Harris hip score. After 5 years follow up there are clinical problems in ceramic on metal THA with decrease clinical score and progressive osteolysis in radiographic finding in 2 cases then we investigated to find the cause of this problem and revise the components. We preformed magnetic resonance imaging and collect blood sample for ESR, CRP and Cobalt and Chromium level. We revised 2 cases of ceramic on metal THA, during surgery we collected tissue for bacterial and AFB and histopathology. All retrieval components were studied for wear pattern. First patient have thigh pain and progressive osteolysis after year 4th of follow up. She had normal ESR and CRP with high level of cobalt and chromium level. We revised both components and tissue histopathology showed metallosis with chronic inflammation. Another patient had failure due to ALTRs with mixed solid-cystic mass at trochanteric bursa but component is stable then only bearing surface were change. Wear pattern at femoral head was in weight bearing area with corresponding to apical center wear of metal liner. Our study showed that only in group of ceramic-on-metal THA that have 5 years follow up have early reoperation due to osteolysis and tissue reaction. We routinely stop to use this bearing since 2010. But we have small number of cases in our study to conclude that is bearing are not suitable for clinical usage.
A retrospective review was conducted of patients undergoing either total hip replacement or hemiarthroplasty for intra-capsular neck of femur fractures between April 2013 and April 2014; identified from entries into the National Hip Fracture Database. PACS and the electronic database encompassing operation notes and discharge summaries were reviewed. 309 patients were identified, 3 of whom fractured both hips during the study period giving a total of 312 operations. The age range was 46 to 102 with a mean age of 82. 59 cemented bipolar hemiarthroplasties, 143 cemented unipolar hemiarthroplasties, 2 uncemented hemiarthroplasties and 108 total hip replacements were performed. 10 patients required further operations. There have been 5 dislocations: 2 underwent MUA only, 2 treated by excision arthroplasty and 1 converted to THR. 1 patient developed a haematoma requiring wound washout. There were 4 wound infections - 1 treated by a washout, 2 by excision arthroplasty and one patient has undergone first stage revision; an overall reoperation rate of 3.2% comparing well with data published elsewhere.
Open reduction and plate fixation of displaced mid-shaft clavicle fractures has gained significant popularity following a recent multi-center randomized control trial. The purpose of this study is to describe the incidence of reoperation following plate fixation of displaced mid-shaft clavicle fractures. The secondary objective is to determine if plate design influences the incidence of reoperation. A retrospective search of our hospital database was performed to identify subjects treated with plate fixation for a displaced clavicle fracture between 2001 and 2009. Radiographs and medical records were used to identify demographic data, fracture classification, plate design, and reoperation events. Only mid-shaft (AO/OTA 15-B) fractures treated with either a Low-Contact Dynamic Compression (LCDC) plate or Pre-contoured Locking (PCL) plate were included.Purpose
