1. Forty patients with solitary eosinophilic granuloma of bone from the Hospital for Sick Children, Toronto, have been reviewed. They had clinical and laboratory findings similar to those reported by others except for the erythrocyte sedimentation rate, which was raised in nearly half the patients tested. 2. Radiographs in all cases showed the lesion to be osteolytic. In the skull and cervical spine there was no bony reaction ; in the thoracic and lumbar spine the typical picture of Calvés disease was produced; in long bones the cortex commonly showed endosteal erosion and periosteal reaction. 3. In one patient the lesion progressed so rapidly that the body of a cervical vertebra was destroyed within ten days. 4. The differential diagnosis includes sarcoma. Biopsy is essential. 5. All the patients improved regardless of the treatment they received.
The PROSTALAC functional spacer is made of antibiotic-loaded acrylic cement but has a small metal-on-polythene articular surface. We have used it as an interim spacer in two-stage exchange arthroplasty for infected total knee replacement. PROSTALAC allows continuous rehabilitation between stages as it maintains good alignment and stability of the knee and a reasonable range of movement. It also helps to maintain the soft-tissue planes, which facilitates the second-stage procedure. We reviewed 45 consecutive patients, treated over a period of nine years. The mean follow-up was for 48 months (20 to 112). At final review, there was no evidence of infection in 41 patients (91%); only one had a recurrent infection with the same organism. There was improvement in the Hospital for Special Surgery knee score between stages and at final review. The range of movement was maintained between stages.
Total hip arthroplasty (THA) is gaining popularity as a treatment for displaced femoral neck fractures (FNFs), especially in physiologically younger patients. While THA for osteoarthritis (OA) has demonstrated low complication rates and increased quality of life, results of THA for acute FNF are not as clear. Currently, a THA performed for FNF is included in an institutional arthroplasty bundle without adequate risk adjustment, potentially placing centres participating in fracture care at financial disadvantage. The purpose of this study is to report on perioperative complication rates after THA for FNF compared with elective THA performed for OA of the hip. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database between 2008 and 2016 was queried. Patients were identified using the THA Current Procedural Terminology (CPT) code and divided into groups by diagnosis: OA in one and FNF in another. Univariate statistics were performed. Continuous variables were compared between groups using Student’s Aims
Patients and Methods
Excellent results can be achieved by plating fractures of the shaft of the humerus in patients with multiple injuries. This helps in nursing care and in the management of other injuries. In 38 patients admitted to a regional trauma centre, 39 humeral shaft fractures were plated. There were 27 men and 11 women, with an average age of 31.5 years. Fourteen of the humeral fractures were compound and 20 had significant comminution; 23 were fixed by a plate on the day of admission and all 39 by the twentieth day. Follow-up of 34 fractures showed that all had united, 33 primarily. All patients but one had a fully functional shoulder and no patient with a fractured humerus alone had lost any elbow movement.
At The Hospital for Sick Children in Toronto, 21 undescended scapulae were corrected by the Woodward procedure in 20 patients over the past 18 years. The average age at operation was six years six months. The average follow-up period after operation was 8 years 9 months. Fifteen patients were girls and five were boys. All the patients had other associated abnormalities. Only one patient had a concomitant clavicular osteotomy. The average increase in glenohumeral abduction was 37 degrees. The average scapular lowering was two centimetres. Excellent or good cosmetic results were obtained in 80 per cent of patients. Ninety-three per cent of patients expressed satisfaction with the operative results.
1. Fifty dislocations and fracture-dislocations of the pelvis have been reviewed. 2.
We reviewed 190 children with brucellosis admitted over a 7.8-year period. Seventy of these had articular involvement (36%) and the most common site was the hip (18%). All but one patient had unilateral infection. The hip was the only joint infected in 20 patients (57%). The next most common articular site was the knee. All patients had painful limitation of movement and this was the only articular sign in 28 (80%). Extra-articular signs included fever and hepatosplenomegaly. Brucella infection should be considered in every child from an endemic area who presents with fever and joint symptoms. The insidious onset and a normal or low leucocyte count help the differentiation from acute septic arthritis. Children with hip involvement had a slower response to treatment, longer hospital stays and a higher incidence of complications and relapse than those without.
We have reviewed 105 Liverpool Mark II knee replacements in 71 patients to assess survival and long-term results. Assessment was both clinical and radiological, using a modification of the British Orthopaedic Association knee function assessment chart, and analysis was by the survivorship method as advocated by Tew and Waugh. The follow-up period was between 13 and 113 months with 42 prostheses being in situ for over six years. Eight knees (7.6%) have been revised or arthrodesed because of infection or loosening, giving a cumulative success rate of 89% after seven years based on prosthesis survival alone. Of the remaining knees, 71.1% were either free of pain or caused only minimal pain. The cumulative success rate as judged by the stricter criteria of the prosthesis being in situ and causing little or no pain suggested a 50% survival between 73 and 96 months. Most patients (77.3%) were enthusiastic or satisfied with their results.
Reverse shoulder arthroplasty (RSA) reliably improves shoulder pain and function for a variety of indications. However, the safety and efficacy of RSA in elderly patients is largely unknown. The purpose of this study was to report the mortality, morbidity, complications, reoperations, and outcomes of primary RSA in patients aged > 80 years. Between 2004 and 2013, 242 consecutive primary RSAs were performed in patients aged > 80 years (mean 83.3 years (Aims
Patients and Methods
The Precice intramedullary limb-lengthening system has demonstrated significant benefits over external fixation lengthening methods, leading to a paradigm shift in limb lengthening. This study compares outcomes following antegrade and retrograde femoral lengthening in both adolescent and adult patients. A retrospective review of prospectively collected data was undertaken of a consecutive series of 107 femoral lengthening operations in 92 patients. In total, 73 antegrade nails and 34 retrograde nails were inserted. Outcome was assessed by the regenerate healing index (HI), hip and knee range of movement (ROM), and the presence of any complications.Aims
Patients and Methods
1. Thirty-three patients who had had stapling of the lower femoral and upper tibial epiphysis to correct inequality of the leg lengths were reviewed after maturity. The staples were inserted so that correction of the disparity would coincide with termination of growth. 2. The predicted corrections were found to be inaccurate. The error was 47 per cent in girls operated on between ten and twelve and 51 per cent in boys between ten and thirteen. In older children the prediction was more accurate. 3. Despite the inaccuracy of prediction only four patients were left with shortening of more than 3·5 centimetres. 4.
1. One hundred and seventy-three hips in 138 patients have been examined and studied in reference to the type of treatment received. 2. Shepherd's method of assessing the results of arthroplasty operations has been adapted to this series. 3. Satisfactory results were found in 77·9 per cent of all patients. 4. The value of straight longitudinal traction is questioned. Medial rotation appears to be an essential step in the reduction of the deformity. 5. Manipulation was found to be a relatively safe and effective method of reducing the deformity in patients seen soon after an acute episode, and should be reserved for them. 6.
We have treated 16 patients with recurrent complex elbow instability using a hinged external fixator. All patients had instability, dislocation or subluxation of the ulnohumeral joint. The injuries were open in eight patients and were associated with 20 other fractures and five peripheral nerve injuries. Two patients had received initial treatment from us; 14 had previously had a mean of 2.1 unsuccessful surgical procedures (1 to 6). The fixator was applied at a mean of 4.8 weeks (0 to 9) after the injury and remained on the elbow for a mean of 8.5 weeks (6 to 11). After treatment we found the mean range of flexion-extension to be 105° (65 to 140). At a final follow-up of 23 months (14 to 40), the mean Morrey score was 84 (49 to 96): this translated into one poor, three fair, ten good and two excellent results.
Severe open fractures of the tibia have a high incidence of complications and a poor outcome. The most usual method of stabilisation is by external fixation, but the advent of small diameter locking intramedullary nails has introduced a new option. We report the early results of a randomised, prospective study comparing external fixation with non-reamed locked nails in grade-IIIb open tibial fractures. Of 29 patients, 15 were treated by nails and 14 by external fixation. Both groups had the same initial management, soft-tissue procedures, and early bone grafting. All 29 fractures healed within nine months, but the nailed group had slightly better motion and less final angulation.
The aim of this study was to assess the feasibility of conducting a full-scale, appropriately powered, randomized controlled trial (RCT) comparing internal fracture fixation and distal femoral replacement (DFR) for distal femoral fractures in older patients. Seven centres recruited patients into the study. Patients were eligible if they were greater than 65 years of age with a distal femoral fracture, and if the surgeon felt that they were suitable for either form of treatment. Outcome measures included the patients’ willingness to participate, clinicians’ willingness to recruit, rates of loss to follow-up, the ability to capture data, estimates of standard deviation to inform the sample size calculation, and the main determinants of cost. The primary clinical outcome measure was the EuroQol five-dimensional index (EQ-5D) at six months following injury.Aims

The aim of this study was to analyze the results of two radiocapitellar prostheses in a large case series followed prospectively, with medium-term follow-up. A total of 31 patients with a mean age of 54 years (27 to 73) were analyzed; nine had primary osteoarthritis (OA) and 17 had post-traumatic OA, three had capitellar osteonecrosis, and two had a fracture. Overall, 17 Lateral Resurfacing Elbow (LRE) and 14 Uni-Elbow Radio-Capitellum Implant (UNI-E) arthroplasties were performed. Pre- and postoperative assessment involved the Mayo Elbow Performance Score (MEPS), the Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) score, and the modified American Shoulder Elbow Surgeons (m-ASES) score.Aims

Acromial fractures following reverse shoulder arthroplasty (RSA) have a wide range of incidences in reported case series. This study evaluates their incidence following RSA by systematically reviewing the current literature. A systematic review using the search terms “reverse shoulder”, “reverse total shoulder”, or “inverted shoulder” was performed using PubMed, Web of Science, and Cochrane databases between 1 January 2010 and 31 March 2018. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. Studies were included if they reported on RSA outcomes and the incidence rate of acromial and/or scapular spine fractures. The rate of these fractures was evaluated for primary RSA, revision RSA, RSA indications, and RSA implant design.Aims
Materials and Methods
There is little literature about total knee arthroplasty (TKA) after distal femoral osteotomy (DFO). Consequently, the purpose of this study was to analyze the outcomes of TKA after DFO, with particular emphasis on: survivorship free from aseptic loosening, revision, or any re-operation; complications; radiological results; and clinical outcome. We retrospectively reviewed 29 patients (17 women, 12 men) from our total joint registry who had undergone 31 cemented TKAs after a DFO between 2000 and 2012. Their mean age at TKA was 51 years (22 to 76) and their mean body mass index 32 kg/m2 (20 to 45). The mean time between DFO and TKA was ten years (2 to 20). The mean follow-up from TKA was ten years (2 to 16). The prostheses were posterior-stabilized in 77%, varus-valgus constraint (VVC) in 13%, and cruciate-retaining in 10%. While no patient had metaphyseal fixation (e.g. cones or sleeves), 16% needed a femoral stem.Aims

A study of a collected series of femoral neck fractures in seventy-one children observed for one to nineteen years shows:. 1. This injury is rare but occurs in children of all ages from three to sixteen years old. 2. The fractures may be classified as transepiphysial, transcervical (the commonest), basal and pertrochanteric. Displacement was frequent. 3. The fracture usually followed severe violence, especially falls from a height or motor accidents. 4.
