Most patients with a nightstick fracture of the ulna are treated conservatively. Various techniques of immobilisation or early mobilisation have been studied. We performed a systematic review of all published randomised controlled trials and observational studies that have assessed the outcome of these fractures following above- or below-elbow immobilisation, bracing and early mobilisation. We searched multiple electronic databases, related bibliographies and other studies. We included 27 studies comprising 1629 fractures in the final analysis. The data relating to the time to radiological union and the rates of delayed union and nonunion could be pooled and analysed statistically.

We found that early mobilisation produced the shortest radiological time to union (mean 8.0 weeks) and the lowest mean rate of nonunion (0.6%). Fractures treated with above- or below-elbow immobilisation and braces had longer mean radiological times to union (9.2 weeks, 9.2 weeks and 8.7 weeks, respectively) and higher mean rates of nonunion (3.8%, 2.1% and 0.8%, respectively). There was no statistically significant difference in the rate of non- or delayed union between those treated by early mobilisation and the three forms of immobilisation (p = 0.142 to p = 1.000, respectively). All the studies had significant biases, but until a robust randomised controlled trial is undertaken the best advice for the treatment of undisplaced or partially displaced nightstick fractures appears to be early mobilisation, with a removable forearm support for comfort as required.

Aims. The aim of this retrospective audit was to determine the route of referral or presentation of patients requiring revision following primary total hip arthroplasty (THA). Patients and Methods. A total of 4802 patients were implanted with an Orthopaedic Data Evaluation Panel (ODEP) 10A* cementless implant (Corail/Pinnacle) between 2005 and 2015; 80 patients with a mean age of 67.8 years (. sd. 10.8) underwent a subsequent revision. The primary outcome measure was route of referral for revision. Results. Of the 80 revisions, 31 (38.8%) took place within the first year and 69 (86.3%) took place within six years. Only two of the 80 patients were picked up at a routine review clinic, one for infection and the other for liner dissociation. A total of 36 revised patients (45.0%) were reviewed following self-referral. Of the remaining 44 revised patients (55.0%), 15 (18.8%) were General Practitioner referrals, 13 (16.3%) were other hospital referrals, six (7.5%) were inpatients, six (7.5%) were Emergency Department referrals, and two (2.5%) were readmitted from their homes. No revisions were carried out on asymptomatic patients. Conclusion. Our experience suggests that if there is a robust system in place for self-referral, patients with an ODEP 10A* hip implant can, if asymptomatic, be safely discharged at the time of their first postoperative review.

Tuberculosis (TB) remains endemic in many parts of the developing world and is increasingly seen in the developed world due to migration. A total of 1.3 million people die annually from the disease. Spinal TB is the most common musculoskeletal manifestation, affecting about 1 to 2% of all cases of TB. The coexistence of HIV, which is endemic in some regions, adds to the burden and the complexity of management. This review discusses the epidemiology, clinical presentation, diagnosis, impact of HIV and both the medical and surgical options in the management of spinal TB.

Aims. The aim of this study was to prepare a scoping review to investigate the use of biologic therapies in the treatment of musculoskeletal injuries in professional and Olympic athletes. Methods. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews and Arksey and O’Malley frameworks were followed. A three-step search strategy identified relevant published primary and secondary studies, as well as grey literature. The identified studies were screened with criteria for inclusion comprising clinical studies evaluating the use of biologic therapies in professional and Olympic athletes, systematic reviews, consensus statements, and conference proceedings. Data were extracted using a standardized tool to form a descriptive analysis and a thematic summary. Results. A total of 202 studies were initially identified, and 35 met criteria for the scoping review; 33 (94.3%) were published within the last eight years, and 18 (51.4%) originated from the USA. Platelet rich plasma was the most studied biologic therapy, being evaluated in 33 (94.3%) studies. Ulnar collateral ligament and hamstring injuries were the conditions most studied (nine (25.7%) studies and seven (20.0%) studies, respectively). Athletes most frequently participated in baseball, soccer, and American football. Only two (5.7%) studies were level 1 evidence, with interpretation and comparison between studies limited by the variations in the injury profile, biologic preparations, and rehabilitation protocols. Conclusion. There is diverse use of biologic therapies in the management of musculoskeletal injuries in professional and Olympic athletes. There is currently insufficient high-level evidence to support the widespread use of biologic therapies in athletes. Further research priorities include the development of condition/pathology-specific preparations of biologic therapies, and of outcome measures and imaging modalities sufficiently sensitive to detect differences in outcomes, should they exist.

Non-traumatic osteonecrosis of the femoral head is a potentially devastating condition, the prevalence of which is increasing. Many joint-preserving forms of treatment, both medical and surgical, have been developed in an attempt to slow or reverse its progression, as it usually affects young patients. However, it is important to evaluate the best evidence that is available for the many forms of treatment considering the variation in the demographics of the patients, the methodology and the outcomes in the studies that have been published, so that it can be used effectively. . The purpose of this review, therefore, was to provide an up-to-date, evidence-based guide to the management, both non-operative and operative, of non-traumatic osteonecrosis of the femoral head. .

Aims. We performed a systematic literature review to define features of patients, treatment, and biological behaviour of multicentric giant cell tumour (GCT) of bone. Methods. The search terms used in combination were “multicentric”, “giant cell tumour”, and “bone”. Exclusion criteria were: reports lacking data, with only an abstract; papers not reporting data on multicentric GCT; and papers on multicentric GCT associated with other diseases. Additionally, we report three patients treated under our care. Results. A total of 52 papers reporting on 104 patients were included in the analysis, with our addition of three patients. Multicentric GCT affected predominantly young people at a mean age of 22 years (10 to 62), manifesting commonly as metachronous tumours. The mean interval between the first and subsequent lesions was seven years (six months to 27 years). Synchronous lesions were observed in one-third of the patients. Surgery was curettage in 63% of cases (163 lesions); resections or amputation were less frequent. Systemic treatments were used in 10% (n = 14) of patients. Local recurrence and distant metastases were common. Conclusion. Multicentric GCT is rare, biologically aggressive, and its course is unpredictable. Patients with GCT should be followed indefinitely, and referred promptly if new symptoms, particularly pain, emerge. Denosumab can have an important role in the treatment.

We have reviewed the current literature to compare the results of surgery aimed to repair or debride a damaged acetabular labrum. We identified 28 studies to be included in the review containing a total of 1631 hips in 1609 patients. Of these studies 12 reported a mean rate of good results of 82% (from 67% to 100%) for labral debridement. Of the 16 studies that reported a combination of debridement and re-attachment, five reported a comparative outcome for the two methods, four reported better results with re-attachment and one study did not find any significant difference in outcomes. Due to the heterogeneity of the studies it was not possible to perform a meta-analysis or draw accurate conclusions. Confounding factors in the studies include selection bias, use of historical controls and high rates of loss of follow-up. It seems logical to repair an unstable tear in a good quality labrum with good potential to heal in order potentially to preserve its physiological function. A degenerative labrum on the other hand may be the source of discomfort and its preservation may result in persistent pain and the added risk of failure of re-attachment. The results of the present study do not support routine refixation for all labral tears. Cite this article: Bone Joint J 2014;96-B:24–30

The timing of total hip replacement (THR) in patients with active tuberculosis (TB) of the hip is controversial, because of the potential risk of reactivation of infection. There is little information about the outcome of THR in these patients. We conducted a systematic review of published studies that evaluated the outcome of THR in patients with active TB of the hip. A review of multiple databases referenced articles published between 1950 and 2012. A total of six articles were identified, comprising 65 patients. TB was confirmed histologically in all patients. The mean follow-up was 53.2 months (24 to 108). Antituberculosis treatment continued post-operatively for between six and 15 months, after debridement and THR. One non-compliant patient had reactivation of infection. At the final follow-up the mean Harris hip score was 91.7 (56 to 98). We conclude that THR in patients with active TB of the hip is a safe procedure, providing symptomatic relief and functional improvement if undertaken in association with extensive debridement and appropriate antituberculosis treatment.

Aims. Patients with a deformity of the hindfoot present a particular challenge when performing total knee arthroplasty (TKA). The literature contains little information about the relationship between TKA and hindfoot alignment. This systematic review aimed to determine from both clinical and radiological studies whether TKA would alter a preoperative hindfoot deformity and whether the outcome of TKA is affected by the presence of a postoperative hindfoot deformity. Methods. A systematic literature search was performed in the databases PubMed, EMBASE, Cochrane Library, and Web of Science. Search terms consisted of “total knee arthroplasty/replacement” combined with “hindfoot/ankle alignment”. Inclusion criteria were all English language studies analyzing the association between TKA and the alignment of the hindfoot, including the clinical or radiological outcomes. Exclusion criteria consisted of TKA performed with a concomitant extra-articular osteotomy and case reports or expert opinions. An assessment of quality was conducted using the modified Methodological Index for Non-Randomized Studies (MINORS). The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and registered in the PROSPERO database (CRD42019106980). Results. A total of 17 studies were found to be eligible for review. They included six prospective and ten retrospective studies, and one case-control study. The effects of TKA showed a clinical improvement in the hindfoot deformity in three studies, but did not if there was osteoarthritis (OA) of the ankle (one study) or a persistent deformity of the knee (one study). The radiological alignment of the hindfoot corrected in 11 studies, but did not in the presence of a rigid hindfoot varus deformity (in two studies). The effects of a hindfoot deformity on TKA included a clinical association with instability of the knee in one study, and a shift in the radiological weightbearing axis in two studies. The mean MINORS score was 9.4 out of 16 (7 to 12). Conclusion. TKA improves both the function and alignment of the hindfoot in patients with a preoperative deformity of the hindfoot. This may not apply if there is a persistent deformity of the knee, a rigid hindfoot varus deformity, or OA of the ankle. Moreover, a persistent deformity of the hindfoot may adversely affect the stability and longevity of a TKA. These findings should be interpreted with caution due to the moderate methodological quality of the studies which were included. Therefore, further prospective studies are needed in order to determine at which stage correction of a hindfoot deformity is required to optimize the outcome of a TKA.

The term developmental dysplasia of the hip (DDH) describes a spectrum of disorders that results in abnormal development of the hip joint. If not treated successfully in childhood, these patients may go on to develop hip symptoms and/or secondary osteoarthritis in adulthood. In this review we describe the altered anatomy encountered in adults with DDH along with the management options, and the challenges associated with hip arthroscopy, osteotomies and arthroplasty for the treatment of DDH in young adults.

We performed a systematic review and meta-analysis of modern total ankle replacements (TARs) to determine the survivorship, outcome, complications, radiological findings and range of movement, in patients with end-stage osteoarthritis (OA) of the ankle who undergo this procedure. We used the methodology of the Cochrane Collaboration, which uses risk of bias profiling to assess the quality of papers in favour of a domain-based approach. Continuous outcome scores were pooled across studies using the generic inverse variance method and the random-effects model was used to incorporate clinical and methodological heterogeneity. We included 58 papers (7942 TARs) with an interobserver reliability (Kappa) for selection, performance, attrition, detection and reporting bias of between 0.83 and 0.98. The overall survivorship was 89% at ten years with an annual failure rate of 1.2% (95% confidence interval (CI) 0.7 to 1.6). The mean American Orthopaedic Foot and Ankle Society score changed from 40 (95% CI 36 to 43) pre-operatively to 80 (95% CI 76 to 84) at a mean follow-up of 8.2 years (7 to 10) (p < 0.01). Radiolucencies were identified in up to 23% of TARs after a mean of 4.4 years (2.3 to 9.6). The mean total range of movement improved from 23° (95% CI 19 to 26) to 34° (95% CI 26 to 41) (p = 0.01). Our study demonstrates that TAR has a positive impact on patients’ lives, with benefits lasting ten years, as judged by improvement in pain and function, as well as improved gait and increased range of movement. However, the quality of evidence is weak and fraught with biases and high quality randomised controlled trials are required to compare TAR with other forms of treatment such as fusion.

Injuries to the hamstring muscle complex are common in athletes, accounting for between 12% and 26% of all injuries sustained during sporting activities. Acute hamstring injuries often occur during sports that involve repetitive kicking or high-speed sprinting, such as American football, soccer, rugby, and athletics. They are also common in watersports, including waterskiing and surfing. Hamstring injuries can be career-threatening in elite athletes and are associated with an estimated risk of recurrence in between 14% and 63% of patients. The variability in prognosis and treatment of the different injury patterns highlights the importance of prompt diagnosis with magnetic resonance imaging (MRI) in order to classify injuries accurately and plan the appropriate management. Low-grade hamstring injuries may be treated with nonoperative measures including pain relief, eccentric lengthening exercises, and a graduated return to sport-specific activities. Nonoperative management is associated with highly variable times for convalescence and return to a pre-injury level of sporting function. Nonoperative management of high-grade hamstring injuries is associated with poor return to baseline function, residual muscle weakness and a high-risk of recurrence. Proximal hamstring avulsion injuries, high-grade musculotendinous tears, and chronic injuries with persistent weakness or functional compromise require surgical repair to enable return to a pre-injury level of sporting function and minimize the risk of recurrent injury. This article reviews the optimal diagnostic imaging methods and common classification systems used to guide the treatment of hamstring injuries. In addition, the indications and outcomes for both nonoperative and operative treatment are analyzed to provide an evidence-based management framework for these patients.

Aims. Periprosthetic fractures (PPFs) around cemented taper-slip femoral prostheses often result in a femoral component that is loose at the prosthesis-cement interface, but where the cement-bone interface remains well-fixed and bone stock is good. We aim to understand how best to classify and manage these fractures by using a modification of the Vancouver classification. Methods. We reviewed 87 PPFs. Each was a first episode of fracture around a cemented femoral component, where surgical management consisted of revision surgery. Data regarding initial injury, intraoperative findings, and management were prospectively collected. Patient records and serial radiographs were reviewed to determine fracture classification, whether the bone cement was well fixed (B2W) or loose (B2L), and time to fracture union following treatment. Results. In total, 47 B2W fractures (54.0%) and one B3 fracture (1.1%) had cement that remained well-fixed at the cement-bone interface. These cases were treated with cement-in-cement (CinC) revision arthroplasty. Overall, 43 fractures with follow-up united, and two patients sustained further fractures secondary to nonunion and required further revision surgery. A total of 19 B2L fractures (21.8%) and 19 B3 fractures (21.8%) had cement that was loose at the cement-bone interface. These cases were managed by revision arthroplasty with either cemented or uncemented femoral components, or proximal femoral arthroplasty. One case could not be classified. Conclusion. We endorse a modification of the original Vancouver system to include a subclassification of B2 fractures around cemented femoral prostheses to include B2W (where cement is well-fixed to bone) and B2L (where the cement is loose). Fractures around taper-slip design stems are more likely to fracture in a B2W pattern compared to fractures around composite beam design stems which are more likely to fracture in a B2L pattern. B2W fractures can reliably be managed with CinC revision. Cite this article: Bone Joint J 2021;103-B(1):71–78

Aims. Improvements in functional results and long-term survival are variable following conversion of hip fusion to total hip arthroplasty (THA) and complications are high. The aim of the study was to analyze the clinical and functional results in patients who underwent conversion of hip fusion to THA using a consistent technique and uncemented implants. Methods. A total of 39 hip fusion conversions to THA were undertaken in 38 patients by a single surgeon employing a consistent surgical technique and uncemented implants. Parameters assessed included Harris Hip Score (HHS) for function, range of motion (ROM), leg length discrepancy (LLD), satisfaction, and use of walking aid. Radiographs were reviewed for loosening, subsidence, and heterotopic ossification (HO). Postoperative complications and implant survival were assessed. Results. At mean 12.2 years (2 to 24) follow-up, HHS improved from mean 34.2 (20.8 to 60.5) to 75 (53.6 to 94.0; p < 0.001). Mean postoperative ROM was flexion 77° (50° to 95°), abduction 30° (10° to 40°), adduction 20° (5° to 25°), internal rotation 18° (2° to 30°), and external rotation 17° (5° to 30°). LLD improved from mean -3.36 cm (0 to 8) to postoperative mean -1.14 cm (0 to 4; p < 0.001). Postoperatively, 26 patients (68.4%) required the use of a walking aid. Complications included one (2.5%) dislocation, two (5.1%) partial sciatic nerve injuries, one (2.5%) deep periprosthetic joint infection, two instances of (5.1%) acetabular component aseptic loosening, two (5.1%) periprosthetic fractures, and ten instances of HO (40%), of which three (7.7%) were functionally limiting and required excision. Kaplan-Meier Survival was 97.1% (95% confidence interval (CI) 91.4% to 100%) at ten years and 88.2% (95% CI 70.96 to 100) at 15 years with implant revision for aseptic loosening as endpoint and 81.7% (95% CI 70.9% to 98.0%) at ten years and 74.2% (95% CI 55.6 to 92.8) at 15 years follow-up with implant revision for all cause failure as endpoint. Conclusion. The use of an optimal and consistent surgical technique and cementless implants can result in significant functional improvement, low complication rates, long-term implant survival, and high patient satisfaction following conversion of hip fusion to THA. The possibility of requiring a walking aid should be discussed with the patient before surgery. Cite this article: Bone Joint J 2021;103-B(7 Supple B):129–134

Aims. Robotic-assisted unicompartmental knee arthroplasty (UKA) promises accurate implant placement with the potential of improved survival and functional outcomes. The aim of this study was to present the current evidence for robotic-assisted UKA and describe the outcome in terms of implant positioning, range of movement (ROM), function and survival, and the types of robot and implants that are currently used. Materials and Methods. A search of PubMed and Medline was performed in October 2018 in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Search terms included “robotic”, “knee”, and “surgery”. The criteria for inclusion was any study describing the use of robotic UKA and reporting implant positioning, ROM, function, and survival for clinical, cadaveric, or dry bone studies. Results. A total of 528 articles were initially identified from the databases and reference lists. Following full text screening, 38 studies that satisfied the inclusion criteria were included. In all, 20 studies reported on implant positioning, 18 on functional outcomes, 16 on survivorship, and six on ROM. The Mako (Stryker, Mahwah, New Jersey) robot was used in 32 studies (84%), the BlueBelt Navio (Blue Belt Technologies, Plymouth, Minnesota) in three (8%), the Sculptor RGA (Stanmore Implants, Borehamwood United Kingdom) in two (5%), and the Acrobot (The Acrobot Co. Ltd., London, United Kingdom) in one study (3%). The most commonly used implant was the Restoris MCK (Stryker). Nine studies (24%) did not report the implant that was used. The pooled survivorship at six years follow-up was 96%. However, when assessing survival according to implant design, survivorship of an inlay (all-polyethylene) tibial implant was 89%, whereas that of an onlay (metal-backed) implant was 97% at six years (odds ratio 3.66, 95% confidence interval 20.7 to 6.46, p < 0.001). Conclusion. There is little description of the choice of implant when reporting robotic-assisted UKA, which is essential when assessing survivorship, in the literature. Implant positioning with robotic-assisted UKA is more accurate and more reproducible than that performed manually and may offer better functional outcomes, but whether this translates into improved implant survival in the mid- to longer-term remains to be seen.

Aims. The aims of this systematic review were to describe the quantity and methodological quality of meta-analyses in orthopaedic surgery published during the last 17 years. Materials and Methods. MEDLINE, EMBASE, and PubMed, between 1 January 2000 and 31 December 2016, were searched for meta-analyses in orthopaedic surgery dealing with at least one surgical intervention. Meta-analyses were included if the interventions involved a human muscle, ligament, bone or joint. Results. A total of 392 meta-analyses met eligibility criteria, for which the mean AMSTAR quality score was 7.1/11. There was a positive correlation between the year of publication and the quality of the meta-analysis (r = 0.238, p < 0.001). Between 2000 and 2011, the mean AMSTAR score corresponded to that of a medium quality review. However, between 2012 and 2016, the mean scores have been consistently equivalent to those of a high-quality review. The number of meta-analyses published increased 10-fold between 2005 and 2014. Conclusion. The quantity and quality of meta-analyses in orthopaedic surgery which have been published has increased, reaching a plateau in 2012. Methodological flaws remain to be addressed in future meta-analyses in order to continue increasing the quality of the orthopaedic literature. Cite this article: Bone Joint J 2018;100-B:1270–4

Aims. Short-stemmed femoral implants have been used for total hip arthroplasty (THA) in young and active patients to conserve bone, provide physiological loading, and reduce the incidence of thigh pain. Only short- to mid-term results have been presented and there have been concerns regarding component malalignment, incorrect sizing, and subsidence. This systematic review reports clinical and radiological outcomes, complications, revision rates, and implant survival in THA using short-stemmed femoral components. Materials and Methods. A literature review was performed using the EMBASE, Medline, and Cochrane databases. Strict inclusion and exclusion criteria were used to identify studies reporting clinical and radiological follow-up for short-stemmed hip arthroplasties. Results. A total of 28 studies were eligible for inclusion. This included 5322 hips in 4657 patients with a mean age of 59 years (13 to 94). The mean follow-up was 6.1 years (0.5 to 20). The mean Harris Hip Score improved from 46 (0 to 100) to 92 (39 to 100). The mean Oxford Hip Score improved from 25 (2 to 42.5) to 35 (12.4 to 48). The mean Western Ontario & McMaster Universities Osteoarthritis Index improved from 54 (2 to 95) to 22 (0 to 98). Components were aligned in a neutral coronal alignment in up to 90.9% of cases. A total of 15 studies reported component survivorship, which was 98.6% (92% to 100%) at a mean follow-up of 12.1 years. Conclusion. Short-stemmed femoral implants show similar improvement in clinical and radiological outcomes compared with conventional length implants. Only mid-term survivorship, however, is known. An abundance of short components have been developed and used commercially without staged clinical trials. Long-term survival is still unknown for many of these components. There remains tension between innovation and the moral duty to ensure that the introduction of new implants is controlled until safety and patient benefit are demonstrated. Implant innovation and subsequent use should be driven by proven clinical outcomes, rather than market and financial forces, and ethical practice must be ensured.

Slipped capital femoral epiphysis (SCFE) is relatively common in adolescents and results in a complex deformity of the hip that can lead to femoroacetabular impingement (FAI). FAI may be symptomatic and lead to the premature development of osteoarthritis (OA) of the hip. Current techniques for managing the deformity include arthroscopic femoral neck osteochondroplasty, an arthroscopically assisted limited anterior approach to the hip, surgical dislocation, and proximal femoral osteotomy. Although not a routine procedure to treat FAI secondary to SCFE deformity, peri-acetabular osteotomy has been successfully used to treat FAI caused by acetabular over-coverage. These procedures should be considered for patients with symptoms due to a deformity of the hip secondary to SCFE.

A delay in the diagnosis of paediatric acute and subacute haematogenous osteomyelitis can lead to potentially devastating morbidity. There are no definitive guidelines for diagnosis, and recommendations in the literature are generally based on expert opinions, case series and cohort studies.

All articles in the English literature on paediatric osteomyelitis were searched using MEDLINE, CINAHL, EMBASE, Google Scholar, the Cochrane Library and reference lists. A total of 1854 papers were identified, 132 of which were examined in detail. All aspects of osteomyelitis were investigated in order to formulate recommendations.

On admission 40% of children are afebrile. The tibia and femur are the most commonly affected long bones. Clinical examination, blood and radiological tests are only reliable for diagnosis in combination. Staphylococcus aureus is the most common organism detected, but isolation of Kingella kingae is increasing. Antibiotic treatment is usually sufficient to eradicate the infection, with a short course intravenously and early conversion to oral treatment. Surgery is indicated only in specific situations.

Most studies were retrospective and there is a need for large, multicentre, randomised, controlled trials to define protocols for diagnosis and treatment. Meanwhile, evidence-based algorithms are suggested for accurate and early diagnosis and effective treatment.

The maintenance of quality and integrity in clinical and basic science research depends upon peer review. This process has stood the test of time and has evolved to meet increasing work loads, and ways of detecting fraud in the scientific community. However, in the 21st century, the emphasis on evidence-based medicine and good science has placed pressure on the ways in which the peer review system is used by most journals. This paper reviews the peer review system and the problems it faces in the digital age, and proposes possible solutions. Cite this article: Bone Joint J 2014;96-B:436–41

Aims. The aim of this study was to investigate the outcomes of Vancouver type B2 and B3 fractures by performing a systematic review of the methods of surgical treatment which have been reported. Materials and Methods. A systematic search was performed in Ovid MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. For inclusion, studies required a minimum of ten patients with a Vancouver type B2 and/or ten patients with a Vancouver type B3 fracture, a minimum mean follow-up of two years and outcomes which were matched to the type of fracture. Studies were also required to report the rate of re-operation as an outcome measure. The protocol was registered in the PROSPERO database. . Results. A total of 22 studies were included based on the eligibility criteria, including 343 B2 fractures and 167 B3 fractures. The mean follow-up ranged from 32 months to 74 months. . Of 343 Vancouver B2 fractures, the treatment in 298 (86.8%) involved revision arthroplasty and 45 (12.6%) were treated with internal fixation alone. A total of 37 patients (12.4%) treated with revision arthroplasty and six (13.3%) treated by internal fixation only underwent further re-operation. . Of 167 Vancouver B3 fractures, the treatment in 160 (95.8%) involved revision arthroplasty and eight (4.8%) were treated with internal fixation without revision. A total of 23 patients (14.4%) treated with revision arthroplasty and two (28.6%) treated only with internal fixation required re-operation. Conclusion. A significant proportion, particularly of B2 fractures, were treated without revision of the stem. These were associated with a higher rate of re-operation. The treatment of B3 fractures without revision of the stem resulted in a high rate of re-operation. This demonstrates the importance of careful evaluation and accurate characterisation of the fracture at the time of presentation to ensure the correct management. There is a need for improvement in the reporting of data in case series recording the outcome of the surgical treatment of periprosthetic fractures. We have suggested a minimum dataset to improve the quality of data in studies dealing with these fractures. Cite this article: Bone Joint J 2017;99-B(4 Supple B):17–25

Aims. Local antibiotics are used in the surgical management of foot infection in diabetic patients. This systematic review analyzes the available evidence of the use of local antibiotic delivery systems as an adjunct to surgery. Materials and Methods. Databases were searched to identify eligible studies and 13 were identified for inclusion. Results. Overall, the quality of the studies was poor. A single trial suggested that wound healing is quicker when a gentamicin-impregnated collagen sponge was implanted at time of surgery, with no difference in length of stay or rate of amputation. Results from studies with high risk of bias indicated no change in wound healing when a gentamicin-impregnated sponge was implanted during transmetatarsal amputation, but a reduction in the incidence of wound breakdown (8% vs 25%, not statistically significant) was identified. A significant cost reduction was identified when using an antimicrobial gel to deliver antibiotics and anti-biofilm agents (quorum-sensing inhibitors) compared with routine dressings and systemic antibiotics. Analyses of case series identified 485 patients who were treated using local antibiotic delivery devices. The rates of wound healing, re-operation, and mortality were comparable to those that have been previously reported for the routine management of these infections. Conclusion. There is a lack of good-quality evidence to support the use of local antibiotic delivery devices in the treatment of foot infections in patients with diabetes.

1. Forty-four cases of Smith's type fractures are reviewed and emphasis laid upon the significance of the different fracture types. 2. Treatment is reviewed and recommendations made for future management

In 1957 Somerville and Scott described their "direct approach" to the management of established congenital dislocation of the hip; arthrography after a period of traction served to distinguish the dislocated from the subluxated hip. We review the long-term outcome of hips which, using their criteria, were subluxated; 72 hips have been reviewed at periods ranging from 15 to 37 years after treatment by traction, closed reduction and femoral osteotomy. The results have been classified clinically and radiologically according to Severin's criteria. There was progressive deterioration with age in both clinical function and radiographic appearance: 48.5% of hips showed evidence of dysplasia or subluxation at review. The results are similar to those found in a series treated by open reduction and limbectomy, differing only in the much lower incidence of degenerative changes after closed reduction

General remarks–Comparison of the two reviews shows that patients with good results return more readily for a review than those with poor results. In middle-aged patients with some disability for walking an attendance of 80 per cent at least is necessary in order to obtain a representative follow-up five to ten years after operation. An outstanding feature of all the operations reviewed is the degree of lasting relief of pain. It is rare to find that a patient with severe hip pain before operation has pain of the same severity after any of these operations at least up to ten years afterwards, and probably for much longer. Generally speaking, although in advancing years stiffness of the hip is undoubtedly a handicap, it is preferable to instability, particularly if this is progressive. A patient can adapt himself to and accept a disability that is permanent and unaltering, but instability increasing in later years can be distressing mentally and incapacitating physically. Cup arthroplasty–There is an element of unpredictability in the results, especially the late results, of cup arthroplasty. Movement decreases and there is a tendency for pain and instability to increase after four or five years. There is little to indicate which case will be successful although the results vary according to the condition for which operation is performed. The operation gives good results, on the whole, for osteoarthritis, particularly when the operation is done on one hip only. Stability is much more important when both hips are involved, and, unless this is good in at least one hip, the results of bilateral operations are poor. "Excellent" results are not obtained in rheumatoid arthritis but few results are "poor." Operations for congenital dislocation of the hip give the most disappointing results. In operations for ankylosing spondylitis there is a high incidence of stiffening of the hip, but many patients are greatly improved in comparison to their state before operation. Displacement osteotomy–The hazard in displacement osteotomy is ankylosis, particularly when internal fixation is not used. Relief of pain and stability are well maintained. The results in general, and for pain in particular, are less good when internal fixation is used. Adduction of the upper fragment of the femur appears to be of value in the production of a good result. In the series examined it was less often achieved when internal fixation was the method of immobilisation. The best results were obtained in cases of congenital dislocation of the hip and there were few "poor" results in cases of congenital subluxation. Excision of the head and neck of the femur and Batchelor's operation–Rehabilitation may take a long time, but the late results are more predictable than in the other operations reviewed. A "fair" result is more likely than an "excellent" one, but late "poor" results are few. Relief of pain is better after excision of the head and neck than after any other operation reviewed

The results of 276 cemented revision total hip arthroplasties performed for aseptic failure between 1977 and 1986 have been reviewed. The mean time between revision and review was 75 months (range 30 to 144). Of 220 cases available for review, 159 were assessed clinically and radiographically, and 32 by postal questionnaire. Eighteen hips required further revision, 12 for loosening, two for sepsis, two for persistent pain, and one each for fracture and recurrent dislocation. A further six hips were radiologically and symptomatically loose. Pain was mild or absent in 83%. Over half were able to walk a mile or more; 70% flexed more than 70 degrees; 15% had a flexion deformity, but in only 7% was this more than 10 degrees. The mean Harris hip score was 74. Survival at five years was 95% and at 10 years, 77%

Improvements in the surgical technique of total knee replacement (TKR) are continually being sought. There has recently been interest in three-dimensional (3D) pre-operative planning using magnetic resonance imaging (MRI) and CT. The 3D images are increasingly used for the production of patient-specific models, surgical guides and custom-made implants for TKR. The users of patient-specific instrumentation (PSI) claim that they allow the optimum balance of technology and conventional surgery by reducing the complexity of conventional alignment and sizing tools. In this way the advantages of accuracy and precision claimed by computer navigation techniques are achieved without the disadvantages of additional intra-operative inventory, new skills or surgical time. This review describes the terminology used in this area and debates the advantages and disadvantages of PSI

Of 111 primary ankle ligament arthroplasties (modified Evans procedure) performed between 1983 and 1994, we were able to identify 89 patients (94 ankles) for follow-up. All were under 50 years of age. Two had died and one refused to co-operate; 86 patients (91 ankles) were therefore reviewed, 25 by telephone and the remainder by clinical examination with all but three also undergoing radiological review. Of the 91 ankles, 70 had no or very mild pain and 72 had no or rare episodes of instability and when considered together only 59 (65%) had no or mild pain and minimal instability. The results were supported by the Karlsson grading system. Clinical examination showed that 17 of the 66 ankles examined had increased inversion, while 21 had some limitation of inversion. Early degenerative changes were seen in 11 ankles, although only four had subtalar changes. These results show that this procedure does not give universally good clinical results. Patient satisfaction, however, was high with 97.7% being willing to undergo the same procedure if their other ankle became similarly affected

Aims

Natural Language Processing (NLP) offers an automated method to extract data from unstructured free text fields for arthroplasty registry participation. Our objective was to investigate how accurately NLP can be used to extract structured clinical data from unstructured clinical notes when compared with manual data extraction.

We report the clinical and radiographic results of the Chiari pelvic osteotomy in 49 hips (45 patients) at an average of 14 years after operation. Of these hips, over half had minimal or no pain, had good or excellent results as assessed by the Harris hip score, and could walk at least three miles; three-quarters, however, had a positive Trendelenburg sign. A younger age at operation and a painless hip with no radiographic evidence of degeneration before operation were associated with a higher hip score at review. The percentage of hips without degenerative changes fell from 68% before operation to 15% at final review. There were no major complications and it was found that a Chiari osteotomy need not interfere with normal childbirth

Forty-one arthrodeses of the shoulder in thirty-nine patients suffering from rheumatoid arthritis (thirty women, nine men) have been reviewed. Using internal fixation and external splints the position of the shoulder was maintained in 55 degrees of abduction, 25 degrees of horizontal flexion and enough internal rotation to allow the patient to reach the mouth. The mean period of immobilisation in a thoracobrachial splint was nine weeks, and 90 per cent of the shoulders had solid bony fusion at review. After arthrodesis the total range of scapulothoracic movement improved by about 60 per cent, giving results rated as excellent in fifteen cases (36 per cent), as good in thirteen (32 per cent) and as fair in thirteen (32 per cent). Arthrodesis can be recommended as an easy, cheap and reliable method of treating a shoulder which has been severely destroyed by rheumatoid arthritis

Antiplatelet agents are widely prescribed for the primary and secondary prevention of cardiovascular events. A common clinical problem facing orthopaedic and trauma surgeons is how to manage patients receiving these agents who require surgery, either electively or following trauma. The dilemma is to balance the risk of increased blood loss if the antiplatelet agents are continued peri-operatively against the risk of coronary artery/stent thrombosis and/or other vascular event if the drugs are stopped. The traditional approach of stopping these medications up to two weeks before surgery appears to pose significant danger to patients and may require review. This paper covers the important aspects regarding the two most commonly prescribed antiplatelet agents, aspirin and clopidogrel

We report a systematic review and meta-analysis of published randomised controlled trials evaluating the efficacy of tranexamic acid (TXA) in reducing blood loss and transfusion in total hip replacement (THR). The data were evaluated using the generic evaluation tool designed by the Cochrane Bone, Joint and Muscle Trauma Group. We identified 11 clinical trials which were suitable for detailed extraction of data. There were no trials that used TXA in revision THR. A total of seven studies (comprising 350 patients) were eligible for the blood loss outcome data. The use of TXA reduced intra-operative blood loss by a mean of 104 ml (95% confidence interval (CI) −164 to −44, p = 0.0006, heterogeneity I. 2. 0%), postoperative blood loss by a mean of 172 ml (95% CI −263 to −81, p = 0.0002, heterogeneity I. 2. 63%) and total blood loss by a mean of 289 ml (95% CI −440 to −138, p < 0.0002, heterogeneity I. 2. 54%). TXA led to a significant reduction in the proportion of patients requiring allogeneic blood transfusion (risk difference −0.20, 95% CI −0.29 to −0.11, p < 0.00001, I. 2. 15%). There were no significant differences in deep-vein thrombosis, pulmonary embolism, infection rates or other complications among the study groups

Aims

Varus-valgus constrained (VVC) implants are often used during revision total knee arthroplasty (TKA) to gain coronal plane stability. However, the increased mechanical torque applied to the bone-cement interface theoretically increases the risk of aseptic loosening. We assessed mid-term survivorship, complications, and clinical outcomes of a fixed-bearing VVC device in revision TKAs.

Shelf arthroplasty is briefly reviewed in historical perspective and the results in 45 hips (39 patients) which had undergone this procedure at the Royal Children's Hospital are presented. The majority of these patients were adolescents who had previously been treated for congenital dislocation or subluxation of the hip. The indications for operation and the operative technique are discussed. Clinical examination was carried out upon 33 of the 39 patients at an average of 11 years after operation. The results suggested that where pain had been an indication for operation almost 80 percent of the hips remained relatively free of symptoms at the time of follow-up and in those patients where acetabular dysplasia had been an indication, the coverage remained good and pain had not appeared. It is concluded that the shelf operation is useful for dealing with both pain and dysplasia in the adolescent

In a retrospective review of 302 clinically suspected cases of congenital syphilis, bone changes were found in 197. The skeletal manifestations were periostitis (102 cases), osteitis (20), and metaphyseal changes (71). Combinations of more than one lesion were found in 61. Pseudoparalysis was a presenting sign in 34 infants; 12 of these were found to have had pathological fractures and four had dactylitis. Complete radiological healing without residual changes was seen in all 59 cases that were recalled for review. The orthopaedic surgeon should consider the diagnosis of congenital syphilis when destructive lesions of bone are seen in an infant

Sixty-two cases of chondrosarcoma of bone were reviewed and histologically graded as low, medium or high-grade tumours. After excluding patients dead from unrelated causes or lost to follow-up, forty cases were available for ten-year follow-up and fifty-eight for five-year follow-up. The rates of survival, recurrence and metastasis were analysed according to the histological grading. Recurrence was further analysed according to the adequacy of treatment. The results were compared with those previously reported in the literature. There was a ten-year survival rate of 58 per cent. Recurrence developed in 58 per cent and was uncontrollable in 29 per cent. The recurrence rate was 87 per cent with inadequate treatment and 15 per cent with adequate treatment. Recurrences outside the limb bones usually proved uncontrollable; recurrences in the limb bones were amenable to further, and if necessary repeated, operations. High-grade chondrosarcoma had a metastatic risk of 75 per cent and eventual mortality of 88 per cent. Medium-grade chondrosarcoma had a metastatic risk of 14 per cent and a mortality of 60 per cent. Low-grade chondrosarcoma had a metastatic risk of 5 per cent and a mortality of 29 per cent

Intravenous tranexamic acid (TXA) has been shown to be effective in reducing blood loss and the need for transfusion after joint replacement. Recently, there has been interest in applying it topically before the closure of surgical wounds. This has the advantages of ease of application, maximum concentration at the site of bleeding, minimising its systemic absorption and, consequently, concerns about possible side-effects. We conducted a systematic review and meta-analysis which included 14 randomised controlled trials (11 in knee replacement, two in hip replacement and one in both) which investigated the effect of topical TXA on blood loss and rates of transfusion. Topical TXA significantly reduced the rate of blood transfusion (total knee replacement: risk ratio (RR) 4.51; 95% confidence interval (CI): 3.02 to 6.72; p < 0.001 (nine trials, I. 2 . = 0%); total hip replacement: RR 2.56; 95% CI: 1.32 to 4.97, p = 0.004 (one trial)). The rate of thromboembolic events with topical TXA were similar to those found with a placebo. Indirect comparison of placebo-controlled trials of topical and intravenous TXA indicates that topical administration is superior to the intravenous route. In conclusion, topical TXA is an effective and safe method of reducing the need for blood transfusion after total knee and hip replacement. Further research is required to find its optimum dose for topical use. Cite this article: Bone Joint J 2014;96-B:1005–15

Reports of excision of the clavicle in the nineteenth century literature are reviewed, and certain operative complications discussed. Osteomyelitis was the most common indication, and was described first in this country by Syme in 1833. The first successful excision of the entire clavicle was performed by McCreary of Kentucky in 1813. The removal of tumour-bearing clavicles provided memorable challenges at a time when anaesthetics were not available, blood transfusion unknown and antibiotic therapy non-existent

A series of 135 knee arthroscopies has been reviewed to determine the accuracy of detection of meniscal lesions. Arthroscopy and double-contrast arthrography achieved similar accuracy (84 per cent and 86 per cent) in the diagnostically more difficult knees of the series. The combined accuracy of both examinations was 98 per cent. Arthroscopic difficulty in seeing the posterior third of the medial meniscus, and consequently tears in this region, is emphasised and discussed. Arthroscopy and arthrography are complementary in the diagnosis of difficult meniscal problems

The results of triple arthrodesis performed in 80 feet and followed for an average of 13 years are reviewed. Although the majority of patients were very pleased, the results of objective assessment were less favourable. There was a high incidence of degenerative joint changes in the ankle and midfoot and also of pseudarthrosis, avascular necrosis of the talus and residual deformity. Pre-operative rigid equinovarus deformity produced the majority of the poor results. It is suggested that bony resection alone might not be the best means of correcting severe equinus

Twenty-four patients treated for tibial shortening secondary to poliomyelitis were reviewed at least 20 years after operation. All subjects were active and only one expressed doubt about the value of tibial lengthening, considering the period of hospitalisation to have been a significant drawback. Approximately five centimetres were added to the length of the treated tibiae. Only one of the nine patients with lengthening of over five centimetres was able to walk at a rate of more than five kilometres per hour, compared with seven of the remaining 15 whose tibiae had been lengthened five centimetres or less

The treatment of acromioclavicular injuries is controversial; few studies document the late results. We have reviewed 53 patients about five years after conservative management, in nine for subluxation and 44 for dislocation. Subjective and objective results were satisfactory in all cases except for one with painful subluxation, who was the only patient to change her occupation because of the injury. At review, joint stability was demonstrated by improvement in position and by the very small increase in the coracoclavicular gap on stress radiographs

We have reviewed a series of 94 Chiari pelvic osteotomies carried out from 1966 to 1982. In 83 hips the indication for surgery had been pain, and of these patients 73 (88%) had appreciable relief within one year of operation. The other 11 hips were all in children and were painless; in them the osteotomy had successfully stabilised progressive subluxation of the hip. At review after a mean follow-up of 10 years (range, 2 to 18 years) 68 previously painful hips were reassessed. Although function of the hips had deteriorated slowly with time, four of the seven cases with 18 years' follow-up had good function and only minor symptoms. A detailed analysis of the radiographic changes produced by the Chiari osteotomy was made, using computerised analysis of variance. The beneficial effects of the osteotomy resulted from complex changes, among which the provision of a stable fulcrum for the hip seemed to be the most important

A case of bilateral avascular necrosis of the capitate is presented. A review of the literature has identified a clear-cut clinical syndrome. The aetiology and pathology of this syndrome is discussed and a new method of treatment is proposed

We reviewed the evidence for hip surveillance in children with cerebral palsy from the published literature. Publications were identified using the Cochrane controlled trials register, the MEDLINE, EMBASE and CINAHL databases and by hand searching key journals and their references. Studies were included if they reported the frequency, associated risk factors or surveillance measures undertaken to identify subluxation or dislocation of the hip in children with cerebral palsy. Assessment of the quality of the methodology was undertaken independently by two researchers. Four studies described the natural history, incidence and risk factors for dislocation of the hip. Two reported their surveillance results. Approximately 60% of children who were not walking by five years of age were likely to develop subluxation of the hip, with the greatest risk in those with severe neurological involvement. The introduction of surveillance programmes allowed earlier identification of subluxation and reduced the need for surgery on dislocated hips. Surveillance can identify children most at risk of subluxation using radiological methods which are widely available

Between 1959 and 1974 the late Dillwyn Evans treated severe symptomatic flat feet by elongating the os calcis. The long-term follow-up of 20 of these patients with a total of 23 feet is presented 7 to 20 years after the operation. At review 17 of the 23 feet showed very good or good results and it was concluded that this is a useful procedure for severe cases of flat feet which appears to stand the test of time

Thirty shoulders, in 20 patients, which had undergone core decompression for symptomatic avascular necrosis of the humeral head were reviewed 2 to 14 years later (average 5.6). Twenty-two showed good or excellent clinical results; the other eight shoulders had required arthroplasty. All 14 shoulders with stage I or II radiological changes (Ficat and Arlet 1980) at operation had good or excellent results. We advocate early core decompression for symptomatic avascular necrosis of the humeral head

We have reviewed 100 Attenborough total knee replacements in eighty-two patients with a follow-up of one to four years and conclude that this prosthesis has a valuable place in the surgical management of patients suffering from rheumatoid arthritis and osteoarthritis with severe involvement of the knee. In 85 per cent of these knees a good result was obtained with relief from pain, and in 77 per cent a useful range of movement with a stable knee. Only two patients with loosening and three with deep infection were seen in this series

We report a retrospective study of 62 total ankle arthroplasties performed between 1972 and 1981. Forty-one of these have been reviewed clinically after an average follow-up of five and a half years; only 13 can be described as satisfactory. The complications encountered in all 62 arthroplasties are detailed, the most significant being superficial wound healing problems, talar collapse, and loosening of the components; 13 prosthetic joints have already been removed and arthrodesis attempted. The management of the complications is discussed. In view of the high complication rate and the generally poor long-term clinical results, we recommend arthrodesis as the treatment of choice for the painful stiff arthritic ankle, regardless of the underlying pathological process

We reviewed 43 patients treated from 1984 to 1988 for open fractures of the pelvis. There were four Gustilo type I wounds, seven type II and 32 type III; 22 fractures were stable and 21 unstable. The overall mortality was 30%; the average Injury Severity Score was 30, being 26 in the survivors and 40 in the fetal cases. We analysed the influence of a number of factors on the mortality rate. The most important were the ISS and the age in years, while the presence of a type III wound and instability of the fracture also had an influence. We describe two simple methods of assessment of the prognosis in individual cases, based on these factors

Thirty-three patients who had undergone anterior cervical fusion for degenerative disc disease were reviewed to determine the efficacy of the procedure. Only patients who were available for examination and who had undergone operation at least one year previously were included in the review. Nearly all had had arm pain and three-quarters neck pain. Diminished neck movement and neurological abnormalities in the arms had been frequent findings. Diagnosis from the clinical features and plain radiographs is described. Myelography was not used routinely and discography was not used at all. Indications for operation and surgical technique are described. Results show that pain in the neck and arm was relieved in a high proportion of cases and that the neurological abnormalities often recovered. It is concluded that this operation is safe and has a definite place in the relief of pain from cervical disc degeneration resistant to conservative treatment

Needle biopsies, performed on 208 consecutive patients and interpreted at the London Bone Tumour Service over a two-year period, were reviewed. A correct diagnosis was reached in 97% (133 out of 137) using this technique alone. Needle biopsy is safe and accurate when undertaken in consultation within a bone tumour service; it offers considerable advantages to both patient and surgeon over conventional open biopsy

Sixty unconstrained elbow replacements of a new design have been followed prospectively for three to nine years. Review showed that 50% had excellent relief of pain and return of function, 27% had had major complications requiring removal or revision of the prosthesis and 23% had minor complications which marred the result. Further research in this field seems worthwhile

We reviewed 19 adults and 12 children who had been treated for avulsion fractures of the tibial spine. Adult injuries have not previously been reported at length; most were caused by road-traffic accidents, and 68% were associated with other injuries, of which 58% were around the knee. The higher incidence of associated injuries in adults as compared with children, indicates that the injury is the result of greater energy and perhaps a different mechanism. The worse outcome in some adults was due to other associated intra-articular fractures and tears of the medial collateral ligament. Arthroscopy is useful in both diagnosis and treatment. Early accurate diagnosis and the correct treatment produce a good outcome

1. One hundred cases of arthrodesis of first metatarso-phalangeal joint have been reviewed after a post-operative interval of at least ten years. 2. Seventy-seven per cent of patients were completely satisfied with the late results ; only 9 per cent were dissatisfied. 3. The two major factors leading to poor results were found to be malposition of the arthrodesis, and interphalangeal osteoarthritis. 4. The ideal position for fusion is considered to be in at least 20 degrees of valgus, preferably between 20 and 30 degrees ; between 20 and 40 degrees of dorsiflexion ; and most importantly, neutral rotation. 5. The precise operative technique is not important provided it maintains the position obtained at operation until the arthrodesis is sound

At re-examination of all osteosarcomata recorded in the Swedish Cancer Registry during the years 1958 to 1968, 11 cases of parosteal osteosarcoma were found. No case of so-called periosteal osteosarcoma was identified. The tumours constituted 1.6 per cent of all proved primary malignant bone tumours. The ages of the 11 patients (six women and five men) ranged from 17 to 62 years (average 33 years). The clinical and histopathological findings of this study and of those collected from a review of the literature suggest the occurrence of two different types of parosteal osteosarcoma: the predominant type is originally benign but has a definite malignant potential, causing metastases after long symptom-free intervals; the other type is highly malignant from the beginning. Primary amputation is recommended for the latter category of tumours, and compartmental, radical en bloc resection followed by regular review is recommended for the former

We reviewed the results of 545 consecutive total hip replacements using a cementless non-coated high-density polyethylene acetabular component combined with a cemented Muller stem at five to 10 years. In all, 421 patients (445 hips) were available for review, 118 by questionnaire and 303 by examination and radiography. Of these, 86% had a good or excellent result. We found a high rate of radiological loosening of the cup after the sixth year, and a high rate of clinical loosening after the eighth year. Loosening was commoner in women, in younger patients and where a smaller size of acetabulum had been used. Calcar resorption was significantly related to loosening of the acetabulum. Loosening appeared to be mainly due to polyethylene debris produced by micro-movement of the acetabulum against the bone, which had resulted in a giant cell foreign body reaction and subsequent bone erosion. We have abandoned the use of this prosthesis and suggest that direct contact between bone and polyethylene should be prevented by a coating of metal or some other material

We reviewed 1085 consecutive compound limb fractures treated in 914 patients at the University of Louisville over a nine-year period. Of these fractures, 240 (group 1) received only systemic antibiotic prophylaxis and 845 (group 2) were managed by the supplementary local use of aminoglycoside-polymethylmethacrylate (PMMA) beads. There were no significant differences in age, gender, fracture type, fracture location or follow-up between the two groups. All had copious wound irrigation, meticulous debridement and skeletal stabilisation, but wound management and the use of local antibiotic depended on the surgeon's individual preference and there was no randomisation. In group 1 there was an overall infection rate of 12% as against 3.7% in group 2 (p < 0.001). Both acute infection and local osteomyelitis showed a decreased incidence in group 2, but this was statistically significant only in Gustilo type-IIIB and type-IIIC fractures for acute infection, and only in type-II and type-IIIB fractures for chronic osteomyelitis. Our review suggests that the adjuvant use of local antibiotic-laden PMMA beads may reduce the incidence of infection in severe compound fractures

We have reviewed 32 patients with rheumatoid disease of the cervical spine who underwent a total of 40 operations aimed at correcting instability and improving any associated neurovascular deficit. Apart from four patients with intractable pain, the main indication for surgery was progressive neurological impairment. Of the 32 primary operations, 19 (60%) were successful; the remainder failed to achieve their objective and there were two deaths in the immediate postoperative period. Of eight secondary operations performed for recurrence of symptoms or failure to relieve cervical myelopathy, only four were successful. Of nine operations for bony decompression to relieve cord compression from irreducible subluxation, only four were successful. The overall results show a success rate of 57% and a failure rate of 35% with early operative mortality in 8%. Indications for operation are discussed and earlier diagnosis is considered to be the key to improved results

A long-term review of 131 children fitted with upper limb prostheses at the Ontario Crippled Children's Centre between 1965 and 1975 is reported. There were 116 children with congenital deficiencies and 15 who had had amputations. Follow-up ranged from 7 to 17 years. A total of 42 children had abandoned their prostheses, 37 of whom had congenital deformities and five were amputees. The level of deficiency was of fundamental importance in determining whether the prosthesis would be accepted; in the forearm, the longer the stump, the more likely it was that the child would discard the prosthesis. Overall, 50 per cent of children fitted over the age of two years abandoned their prostheses compared with only 22 per cent of patients who had been fitted before the age of two years. The highest drop-out rate was at the age of 13 years when the children became more conscious of their cosmetic appearance. Suggestions for reducing the high drop-out rate in the early teens are put forward

Thirty-five patients (28 children and seven adults) were reviewed six months to 22 years after sustaining the common childhood fracture of the intercondylar eminence of the tibia. The aim was to assess both short-term and long-term results and prognosis by clinical and radiological examination and to discover whether conservative treatment was adequate for those severe fractures where a fragment of the tibial crest had been totally displaced. All the less severe fractures and 14 of the 17 severe fractures were treated conservatively. Early improvement occurred in more patients when the knee was immobilised in extension rather than in flexion, but long-term results were similar. Seven patients had slight discomfort, two of whom had had operative treatment. Radiographs of all patients showed a projection at the fracture site but its size did not correlate with the extent of displacement of the fragment nor with the degree of discomfort suffered; in the severe group a smaller projection developed after open reduction and after immobilisation in extension than after immobilisation in flexion. There was no instability due to functional lengthening of the cruciate ligaments and no increased incidence of degenerative change

In 1957 Somerville and Scott presented their principles of management for the older child with congenital hip dislocation. They advocated preliminary traction followed, in those hips which remained dislocated, by excision of the limbus and subsequent derotation varus osteotomy of the femur. As alternative regimes are advocated it becomes increasingly important to subject each method to detailed long-term review. One hundred and forty-seven hips in 121 patients aged between 12 months and three years and treated by the standard Somerville and Scott regime have been reviewed. The age at review ranged from 16 to 31 years. The recall rate was 91 per cent. Each patient was seen regularly in a special clinic where detailed notes, radiographs and records were available. The results have been assessed clinically and radiographically by modifications of Severin's criteria to enable comparisons to be made with other published series. Attention has been focused on the good and the bad prognostic factors and on the long-term complications. The most worrying feature has been the premature onset of degenerative arthritis even in hips which seemed to have been satisfactorily reduced

Successful management of late presenting hip dislocation in childhood is judged by the outcome not just at skeletal maturity but well beyond into adulthood and late middle age. This review considers different methods of treatment and looks critically at the handful of studies reporting long-term follow-up after successful reduction.

Primary skin closure after the surgical correction of severe club-foot may be difficult. We describe the use of a tissue expander to provide sufficient skin, and review some aspects of the use of the method

We present the case of a 65-year-old man who developed a malignant fibrous histiocytoma at the lesser trochanter five months after a cementless hip replacement. We have reviewed reports of similar cases and discuss them in terms of the possible mechanisms of sarcomatous degeneration and the latency of such changes

Malignant transformation of fibrous dysplasia to chondrosarcoma is rare. We report a case in which malignancy developed in an area of fibrous dysplasia in the ilium. We believe this to be the second reported case at this site. Treatment was by excision of the hemipelvis including the ala of the sacrum. A review of the literature is presented

We reviewed the records and radiographs of 387 cemented revisions of aseptic loose sockets after total hip replacement at a mean follow-up of 5.5 years. The clinical results were satisfactory, but at the last radiological assessment 38 sockets (9.8%) had a continuous zone of demarcation greater than 1 mm thick and another 35 (9%) showed migration. Poor acetabular bone stock had a profound influence on the outcome of revision surgery, but the results of cemented revision were comparable to those reported for cementless revision at similar mean follow-up

The early results of revision osteoarticular allografts in weight-bearing joints are reported. Sixteen consecutive patients underwent surgery over a six-year period between 1982 and 1988. At the time of review eight patients (50%) had surviving second allografts with an average follow-up time of 48 months (range 12 to 87). Five patients were graded excellent according to the Mankin scale, one good and two fair. Eight patients (50%) required further surgery, but only two patients came to amputation

We have reviewed 22 patients with scaphoid fractures treated by internal fixation with the Herbert screw. Three patients had trans-scaphoid perilunar dislocations, one had an oblique displaced fracture of the waist of the scaphoid and 18 had fractures with delayed or non-union. Corticocancellous bone grafts were added in nine of the cases of non-union. Results were excellent or good in 80% of cases after a mean duration of postoperative immobilisation of four weeks. The technical difficulties are analysed and the problems of applying the jig and of operative exposure are discussed

Seventy-nine cases of fracture of the femoral shaft treated by cast-brace and early walking have been reviewed. Discrepancy in femoral length was assessed by scanogram. The cases were analysed to relate the incidence of shortening greater than 2 centimetres to the type and site of the fracture, and the time which elapsed from injury until the cast-brace was applied. Such shortening was encountered most frequently when the cast-brace was applied within the first two weeks from injury or after six weeks and in those patients with comminuted fractures of the middle third of the femoral shaft

Of 64 patients with stab wounds involving the brachial plexus operated on by one surgeon, 18 were followed up in detail, with a view to reviewing operative techniques, results and the lessons to be learned. Primary nerve grafting produced better results than end-to-end repair, even in fresh cases. The recognition of nerve compression by a false aneurysm is important, since in these cases, vascular repair alone may not give recovery and neurolysis may be necessary. The overall results of operation were good; lesions of C5 and C6 roots recovered better than those of more distal roots

A review is presented of 41 patients with traumatic tetraplegia on whom reconstructive surgery of the upper limb was carried out. Twelve patients were followed up for more than 10 years after operation and the average period overall was seven and a half years. Tendon transfers were made with the aim of providing extension of the elbow or restoring a useful grasp or a combination of both. The assessment was carried out on four main aspects: the function of the elbow, the function of the hand, the ability to carry out the activities of daily living and the effect of the surgical reconstruction on the personal and social achievement of the patient

Solitary benign peripheral-nerve tumours are rare and may be difficult to diagnose correctly. Surgical excision may increase the patient's symptoms and may not be necessary. We have reviewed the presentation, clinical findings and histology of 104 solitary tumours presenting at one centre between 1959 and 1990. Male patients predominated for both schwannoma and neurofibroma. There was considerable but variable delay before presentation; 94% of patients complained primarily of a mass and less than half had pain or paraesthesia. The correct diagnosis had been made in only a few cases before operation, and the incidence of neurological symptoms doubled after exploration. We emphasise the need for vigilance, accurate preoperative diagnosis, and careful surgery

We reviewed at a minimum elapsed time of five years a consecutive series of 143 primary Exeter hip replacements in which matt-surfaced femoral stems had been used. Twenty-five patients had died and six stems and two sockets had been revised before follow-up. The remaining 110 hips were all examined clinically and radiographically. In 15 hips there were radiographic signs of definite loosening of the stem and in eight suspected loosening. The acetabulum was loose in four hips. In another eight hips localised bone resorption was present without signs of loosening. Half the patients with loosening or localised bone resorption had mild pain or no pain at all. The late complication rate with the matt-surfaced Exeter femoral stem is unacceptably high

After severe poliomyelitis, which is still relatively common in some developing countries, lateral rotation deformity of the tibia may occur. We have reviewed 51 patients treated by O'Donoghue's rotation osteotomy of the tibia. An average lateral rotation deformity of 57 degrees was fully corrected in all the patients, and in 38 of them the graft obtained during the osteotomy was used for a simultaneous Grice-Green subtalar arthrodesis in one or both feet. All the osteotomies united in an average of 11 weeks, some with relatively minor and unintentional posterior angulation. There was no posterior angulation when the length of the step cut osteotomy was 4.5 cm or more. O'Donoghue's osteotomy is a simple and safe operation, being particularly advantageous if a Grice-Green procedure is also required

Aims

There is uncertainty regarding the optimal means of thromboprophylaxis following total hip and knee arthroplasty (THA, TKA). This systematic review presents the evidence for acetylsalicylic acid (aspirin) as a thromboprophylactic agent in THA and TKA and compares it with other chemoprophylactic agents.

From 1948 to 1980, 93 children and adolescents had fusion in situ for severe spondylolisthesis with a slip of 50% or more, at a mean age of 14.8 years. Of these, 52 girls and 35 boys were reviewed after a mean follow-up of 13.8 years. The mean pre-operative slip was 76% and pain frequency correlated with the severity of the lumbosacral kyphosis but not with that of the slip. Posterior fusion was used in 54, posterolateral in 30 and anterior fusion in three patients. There were no major complications but 16 had re-operations for non-union or root symptoms. At follow-up there were three non-unions. After operation, 19 patients had 10% or more progression of the slip, but 10 showed correction by more than 10% as a result of remodelling. The lumbosacral kyphosis had increased by more than 10 degrees in 45%. Postoperative progression of the slip and of lumbosacral kyphosis was significantly more if the posterior element had been removed. At follow-up 77 patients were subjectively improved, four were unchanged, and one was worse. These results did not correlate with either the degree of the slip, or the angle of lumbosacral kyphosis. Fusion in situ is safe and gives good long-term clinical results. Secondary changes are associated with increased lumbosacral kyphosis, so reduction of this should be considered in severe cases

Aim

Until now, there has been no consensus as to whether stemmed acetabular components are appropriate for use in patients undergoing revision total hip arthroplasty (THA) who have major acetabular defects or pelvic discontinuity. We wished to address this deficiency in the literature.

We studied the pathogenesis, incidence and consequences of avascular necrosis in 184 children treated for congenital dislocation of the hip. Of 210 hips, 99 (47%) had some evidence of avascular necrosis (total 81, partial 18). The incidence was not influenced by the age at reduction, the duration of traction or the use of adductor tenotomy. Patients treated by closed reduction without preliminary traction did not have a higher incidence of avascular necrosis. At long-term clinical and radiological review of 81 hips, early avascular necrosis significantly increased the chance of a poor outcome but did not predispose to acetabular dysplasia. If review includes minor forms of avascular necrosis, then this condition is common after closed reduction. Its presence is an important determinant of long-term radiological and clinical outcome

The place and effectiveness of surgery for acromioclavicular dislocation is disputed. We have reviewed 29 patients all treated by an operation which holds the clavicle down to the coracoid process. This was effective in both acute and late cases, with rapid return to work, a low incidence of complications and no requirement for secondary procedures. We consider it to be the method of choice when operation is indicated

To assess the effect of improved methods of femoral cementing on the loosening rates in young patients, we reviewed 50 'second-generation' cemented hip arthroplasties in 44 patients aged 50 years or less. The femoral stems were all collared and rectangular in cross-section with rounded corners. The cement was delivered by a gun into a medullary canal occluded distally with a cement plug. A clinical and radiographic review was undertaken at an average of 12 years (10 to 14.8) and no patient was lost to follow-up. No femoral component was revised for aseptic loosening, and only one stem was definitely loose by radiographic criteria. By contrast, 11 patients had undergone revision for symptomatic aseptic loosening of the acetabular component and 11 more had radiographic signs of acetabular loosening

We report the cases of teenage twin girls presenting within months of each other with severe symptoms from lumbosacral disc prolapses, requiring laminectomy in one and chemonucleolysis in the other. CT scans showed similarities in spinal configuration, including the presence of disc bulges at the L4-5 level. This suggests a strong hereditary factor in prolapse of intervertebral discs, but a review of the literature showed little information on that aspect

We report the long-term results of the Matti-Russe operation for pseudarthrosis of the scaphoid in 100 cases, reported previously by Mulder in 1968. Clinical results for 77 patients and radiographic data for 74 were reviewed at 22 to 34.8 years after surgery. In general, there was satisfactory relief of pain and stiffness but some patients had limitation of motion and reduced grip-strength, with usually slight osteoarthritic changes. There was poor correlation between subjective, objective, and radiographic results but 88% of the patients were satisfied with their results

A family of 114 people in six generations, of whom 45 were affected by multiple epiphysial dysplasia, was described in this Journal in May 1960. We have been able to review them again 23 years later, and also to report on the type and incidence of the disease in more children and in a further generation. The relative severity of the disease in different branches of the family has been unchanged through the generations. Patients who were previously hopelessly crippled can today be rehabilitated by total hip replacement. Genetic counselling and birth control have reduced the relative and absolute numbers of affected children; this is tending to make the disease self-limiting

Total hip replacement has been very successful in patients with painful, stiff hips associated with protrusio acetabuli, but the heat of polymerisation of methylmethacrylate cement may cause necrosis of the thin medial wall with consequent danger of migration of the cup. Since 1968 at Wrightington, thin slices of the head of the femur have been used as bone grafts to reinforce the acetabulum. We have reviewed 61 hips in 51 patients at an average of 4 years 3 months after operation. Grading for severity is discussed and the degree of physiological remodelling of the medial wall of the acetabulum after grafting assessed. There was an average of about 4 mm of remodelling, but this varied considerably; most took place within the first year. In no case was there relapse of the protrusio

A modified form of the collateral operation originally described by Dillwyn Evans has been used in severe relapsed club feet to correct the sagittally breached or bean-shaped foot. Forty-five feet in 37 patients were followed up for an average of nine years and nine months. Previous operations had been performed on 42 feet. Thirty out of 45 feet were considered satisfactory at review when evaluated by a simple, functional system of scoring. The majority of the feet were stiff but relatively free of pain and able to fit into normal shoes. The collateral operation was considered successful in 42 feet if the patient's ability to take part in any desired sporting and recreational activities was taken as the criterion for success

Forty-four feet in 28 children previously treated by a one-stage posteromedial release operation (the Turco procedure) were reviewed clinically and radiologically to determine the cause of residual adduction of the forefoot. In 21 clinically adducted feet (48%) the main cause of residual deformity was metatarsus varus alone or metatarsus varus in spite of talonavicular overcorrection; in five feet the cause was talonavicular subluxation. There was no residual adduction in 23 feet (52%) but only 12 had normal radiographic measurements. In the remaining feet, various forms of spurious correction of metatarsus varus and talonavicular subluxation or both were seen, resulting in normal-looking feet. Recession of the origin of abductor hallucis and release of the short plantar muscles and fascia at the time of posteromedial release is recommended. The forefoot adduction was satisfactorily corrected in 91% of the feet subsequently operated on using this modified procedure

We reviewed 195 knees in 167 patients at least 20 years after a rim-preserving meniscectomy. They were considered in two groups: 102 knees had had an intact anterior cruciate ligament (ACL), and 93 had had an unrepaired rupture. More patients with a ruptured ACL had downgraded their sport activity by five years after meniscectomy. The incidence of radiographic osteoarthritis was about 65% at 27 years in patients with a ruptured ligament, and 86% in those followed up for over 30 years. In the ligament-deficient group 10% had had operations for osteoarthritis, and another 28% had had other operations, mainly further meniscectomies. Only 6% of those with an intact ligament had needed a second operation after meniscectomy and at long-term follow-up 92% of them were satisfied or very satisfied. Only 74% of the ligament-deficient patients were satisfied with their result. The long-term outcome after rim-preserving meniscectomy depends mainly upon the state of the anterior cruciate ligament

Of a total of 905 patients with fracture or fracture-dislocation of the thoracolumbar spine admitted from 1969 to 1982, a neurological deficit was present in 334 (37%). All unstable injuries were initially treated by reduction and posterior fusion. In 79 of these patients, an anterolateral decompression was undertaken later because of persistent neurological deficit and radiographic demonstration of encroachment on the spinal canal. One patient died of pulmonary embolism; 78 were reviewed after a mean period of four years. Of these 78 patients 18 made a complete neurological recovery while 53 appeared to have benefited from the procedure; 25 remained unchanged. The best results were obtained in burst fractures at thoracolumbar and lumbar levels when a solitary detached fragment of a vertebral body had been displaced into the spinal canal. These results indicate that anterolateral decompression of the spinal canal should be considered, after careful evaluation, for certain injuries of the spine in which there is severe neural involvement

Ten patients who suffered iatrogenic injury to a vertebral artery during anterior cervical decompression were reviewed to assess the mechanisms of injury, their operative management, and the subsequent outcome. All had been undergoing a partial vertebral body resection for spondylitic radiculopathy or myelopathy (4), tumour (2), ossification of the posterior longitudinal ligament (1), nonunion of a fracture (2), or osteomyelitis (1). The use of an air drill had been responsible for most injuries. The final control of haemorrhage had been by tamponade (3), direct exposure and electrocoagulation (1), transosseous suture (2), open suture (1), or open placement of a haemostatic clip (3). Five patients had postoperative neurological deficits, but most of them resolved. We found direct arterial exposure and control to be safe, quick and reliable. Careful use of the air drill, particularly in pathologically weakened bone, as in infection or tumour, is essential. Arterial injury is best avoided by a thorough knowledge of the anatomical relationships of the artery, the spinal canal, and the vertebral body

We have reviewed 402 traumatic fractures of the femoral shaft, 320 of which had been treated by operation and had a long follow-up. Of these, 228 closed fractures and 37 open fractures had been stabilised by plating. There was no significant difference in healing between those stabilised early and those having delayed internal fixation. Re-fracture after removal of the implant occurred more often after early operation. All 55 fractures treated by intramedullary nailing healed and there were no re-fractures after nail removal. We found no correlation between delay before operation and the incidence of postoperative infection

We reviewed the cases of 38 children with 45 congenitally dislocated hips who presented for primary treatment after the age of three years. Of these, 34 hips were managed by the 'direct approach' of Somerville and Scott (1957); 14 of these required secondary operations for subluxation, often with a poor outcome. Eleven hips were treated by combined pelvic and femoral osteotomy which, in general, gave good results. At a mean follow-up of 16.7 years, 80% of the whole series had a good or excellent clinical result and 51% were good or excellent radiologically. Simultaneous correction both above and below the hip is considered to be the best treatment for the older child with congenital hip dislocation

We report the use of a free tendon graft in 70 patients to repair lesions of the capsuloligamentous complex of the metacarpophalangeal joint of the thumb. Of these 37 had a lesion of the ulnar collateral ligament, 18 of the radial collateral and 11 of the volar plate. Four patients had combined lesions. We outline our techniques and review 51 of the patients. Of those 47 (92%) were satisfied, and all but one had regained full stability. Pinch grip strength was normal in 48. About one-third of the patients had some loss of flexion/extension; this was seldom noticed by the patients and caused no significant disability. Free tendon graft reconstruction is indicated for severe fresh lesions, for old lesions with chronic disability and for lesions which have not responded to conservative management

We made a prospective study of 241 Charnley total hip replacements performed between 1968 and 1974. In 1990, we reviewed 92 patients with 103 hips (96.3% of surviving hips) at a mean follow-up of 17.6 years (15 to 20.6) The clinical results were excellent, with Charnley scores of 4 or more for pain in 95% of the patients, for function in 73% and for movement in 93%. Of the whole series, 8.3% had been revised, and Kaplan-Meier survival analysis showed a probability of revision at 20 years of 10.7%. These results are similar to those from the few other series with extended follow-up, and make it difficult to justify the present widespread use of uncemented hip prostheses. It would seem that some aspects of the design of the first-generation Charnley stem were beneficial for long-term survival of the arthroplasty. We found no correlation between the clinical results and radiological loosening on the Harris scale

We reviewed and radiographed 30 skeletally-mature patients after isolated closed femoral shaft fractures in childhood which had been treated conservatively. When the fracture had occurred between the ages of 7 and 13 years, the limb overgrew about 1 cm regardless of sex, upper limb dominance, age, fracture site or configuration. Excessive fracture overlap at the time of injury, but not at union, increased limb overgrowth. Angulation of the fracture remodelled in children injured under 10 years of age, but in older patients this sometimes added to limb shortening. Rotational deformities were minor and gave no symptoms. Treatment of the 7- to 13-year-old patient should aim at 1 cm overlap at union, with correction of angular deformity being more important in children over 10 years of age. This management of fractures will give a maximum leg length discrepancy of 1 cm at skeletal maturity

Forty-four patients who had undergone 50 capsular arthroplasties for congenital dislocation of the hip were reviewed after a mean follow-up of 20 years. Their average age at operation was 5.9 years; 31 of the operations were undertaken because of late presentation, the remainder because of the failure of previous surgery. In all, 70% of the hips showed good function despite a reduced range of movement, but patients with bilateral arthroplasties fared poorly. Excellent containment within the acetabulum was found in 80%, but the femoral head was always abnormally high though not unduly lateral or medial. This configuration had remained unchanged during follow-up. The accuracy of reduction along the mediolateral axis was the only variable found to influence the outcome significantly. Functional deterioration, associated with pain, was noted to be more common after 20 years than before, and was associated with radiographic evidence of joint degeneration
