Femoral lengthening has been associated with narrowing of the joint space at the hip. We have studied the joint space before lengthening in 20 patients with a short femur due to a femoral-shaft fracture (15) or distal femoral epiphyseal injury (5). Their mean age at injury was 16 years (3 to 27) and the mean shortening was 5.4 cm (1.1 to 14). We found that the hip joint space of the shortened femur was significantly narrower (p < 0.001) than that on the normal side, with a mean narrowing ratio of 15.5% (−5 to +43). The narrowing ratio was directly related to the period spent non-weight-bearing (p < 0.001), but not to the amount of femoral shortening. We have shown that the joint space of the hip in patients with post-traumatic femoral shortening was narrowed even before femoral lengthening had been started

Sixty-one patients with 68 osteonecrotic femoral heads, at different stages of development, were treated surgically; their average age was 36 years. Necrosis followed a fracture in 43 hips and traumatic dislocation in three. It was idiopathic in 14, cortisone-induced in seven and associated with gout in one. The operation of multiple drilling, curettage of the necrotic bone and muscle pedicle bone grafting was performed in all. Cheilectomy of the superolateral part of the femoral head and adductor tenotomy were added in cases of advanced necrosis. Of the several types of muscle pedicle used, tensor fasciae latae anteriorly and quadratus femoris posteriorly were preferred. Full weight-bearing was not permitted for five to six months. The follow-up period varied from three to 12 years. Hip pain was regularly relieved and abduction and rotation of the joints were improved. Those with post-traumatic or idiopathic necrosis did better than those with cortisone-induced necrosis

The late results of treatment of calcaneal fractures in 17 children (19 fractures) were reviewed at a mean of 16.8 years after injury. With the exception of one patient, all fractures had been treated conservatively. At follow-up there were few complaints. All but two patients had full or slightly reduced mobility of the subtalar joint and unrestricted foot function, including the ability to walk comfortably on uneven surfaces. Minor radiological abnormalities of the hindfoot were common; there were two cases of post-traumatic osteoarthritis. Clinical scoring of the ankle and hindfoot using the American Orthopaedic Foot and Ankle Society rating system averaged 96.2 points. The results suggest that up to 16.8 years after injury almost all children achieve excellent long-term functional results with conservative treatment of fractures of the os calcis. Open management may only be appropriate for adolescents with severe displacements

Aims

Dual mobility (DM) bearings are an attractive treatment option to obtain hip stability during challenging primary and revision total hip arthroplasty (THA) cases. The purpose of this study was to analyze data submitted to the American Joint Replacement Registry (AJRR) to characterize utilization trends of DM bearings in the USA.

Aims

We studied the safety and efficacy of multimodal thromboprophylaxis in patients with a history of venous thromboembolism (VTE) who undergo total hip arthroplasty (THA) within the first 120 postoperative days, and the mortality during the first year. Multimodal prophylaxis includes discontinuation of procoagulant medications, VTE risk stratification, regional anaesthesia, an intravenous bolus of unfractionated heparin prior to femoral preparation, rapid mobilization, the use of pneumatic compression devices, and chemoprophylaxis tailored to the patient’s risk of VTE.

Aims

Conservative treatment of moderately displaced proximal humeral head fractures yields good clinical results, but secondary fragment displacement may occur. Identification of those fractures at risk of displacement may influence initial decision-making.

Aims

Despite advances in the treatment of paediatric hip disease, adolescent and young adult patients can develop early onset end-stage osteoarthritis. The aims of this study were to address the indications and medium-term outcomes for total hip arthroplasty (THA) with ceramic bearings for teenage patients.

From 1979 to 1990 we treated 20 patients with large bone defects or established nonunion of the femur by vascularised fibular grafts. There were 18 men and two women with an average age at operation of 36.6 years (16 to 69). Ten patients had infected nonunion, three had post-traumatic nonunion or a bone defect without infection, four had a defect after tumour resection, and three had other lesions. The mean length of the fibular grafts was 18.1 cm. Postoperative circulatory disturbances needed revision surgery in five patients, including three with circulatory problems in the monitoring flap, but not at their anastomoses. The outcome was successful in 19 of the 20 patients with bone union at means of 6.1 months at the proximal site and 6.6 months at the distal site. Three patients had fractures of the fibular grafts but all these united in two to three months after cast immobilisation

Although the outcome of fractures of the distal radius is traditionally assessed using objective clinical variables such as grip strength and range of movement of the wrist, the extent to which they reflect function and outcomes of importance for the patient is uncertain. This may cause considerable inconsistencies in the assessment of outcome using current scoring systems. We prospectively studied 31 patients recovering from unstable fractures of the distal radius in order to investigate the association between objective variables and the level of post-traumatic disability of the wrist as measured by the patient-rated wrist evaluation (PRWE) score. Multiple regression showed considerable differences in the extent to which limitations in specific objective clinical variables reflected the level of disability of the wrist. Grip strength was shown to be a significant predictor of the PRWE score (regression coefficient −1.09, 95% confidence interval −1.76 to −0.42, p < 0.01) and thus appears to be a sensitive indicator of return of function of the wrist. Forearm rotation and flexion and extension of the wrist were not significantly associated with the PRWE score. These observations should be taken into account during the evaluation of methods of treatment and in constructing future clinical outcome scoring systems

Aims

Eight-plates are used to correct varus-valgus deformity (VVD) or limb-length discrepancy (LLD) in children and adolescents. It was reported that these implants might create a bony deformity within the knee joint by change of the roof angle (RA) after epiphysiodesis of the proximal tibia following a radiological assessment limited to anteroposterior (AP) radiographs. The aim of this study was to analyze the RA, complemented with lateral knee radiographs, with focus on the tibial slope (TS) and the degree of deformity correction.

Aims

The purpose of this study was to: review the efficacy of the induced membrane technique (IMT), also known as the Masquelet technique; and investigate the relationship between patient factors and technique variations on the outcomes of the IMT.

Tibiotalar fusion is considered to be the standard treatment for end-stage post-traumatic arthritis of the ankle. We report a retrospective, objective long-term study of the quality of life of 17 patients with 18 arthrodeses of the ankle, over a period of more than 20 years. We looked particularly for correlation between clinical and radiological signs of osteoarthritis in adjoining joints. At serial physical examinations, clinical grades were awarded according to the Olerud Molander Ankle (OMA) score. Any degree of degenerative change in the adjoining joints was recorded on standing radiographs. Patients filled out a SF-36 Health Survey form. Subjectively, 50% of patients were not handicapped in the performance of daily activities and 44% were in the same job as at the time of injury. At follow-up the mean OMA score was 59.4 points, the visual analogue scale was 1.99 and the radiological score was 2.7. The SF-36 for physical function, emotional disturbance and bodily pain revealed significant deficits. There was a significant correlation between the OMA and the radiological score (p = 0.05), and between the clinical and the SF-36 score (p = 0.01), but no significant correlation between the radiological score and the SF-36 score. Arthrodesis of the ankle leads to deficits in the functional outcome, to limitations in the activities of daily living and to radiological changes in the adjoining joints. The clinical outcome score correlates closely with the SF-36 score

We report the incidence of osteolysis in the femur, tibia, and patella of 44 consecutive patients (60 knees) who were followed for more than seven years after cementless knee arthroplasty with a Porous-Coated Anatomic prosthesis. The average age of the patients was 56.5 years (17 to 73); the operative diagnosis was osteoarthritis (33 knees), rheumatoid arthritis (17), tuberculous arthritis (7) and post-traumatic arthritis (3). All patellae were resurfaced. No femoral or tibial component was loose at the final follow-up examination. Thirty patellar components were loose of which six had been revised. Radiographs revealed osteolysis in 90% of the tibial plateaux and in 80% of the 30 intact patellar prostheses. No osteolysis was seen around any femoral component. In 50 knees (83%) the average wear of the polyethylene liner was 2.5 mm in the medial compartment and 1.7 mm in the lateral compartment. Four of 60 knees (6.7%) were revised for complete wear of the polyethylene liner of the tibial component. Fixation of the tibial and patellar components without cement fails to seal the interface between bone and prosthesis and allows the migration of polyethylene particulate debris which causes osteolysis

Autologous chondrocyte implantation (ACI) and mosaicplasty are both claimed to be successful for the repair of defects of the articular cartilage of the knee but there has been no comparative study of the two methods. A total of 100 patients with a mean age of 31.3 years (16 to 49) and with a symptomatic lesion of the articular cartilage in the knee which was suitable for cartilage repair was randomised to undergo either ACI or mosaicplasty; 58 patients had ACI and 42 mosaicplasty. Most lesions were post-traumatic and the mean size of the defect was 4.66 cm. 2. The mean duration of symptoms was 7.2 years and the mean number of previous operations, excluding arthroscopy, was 1.5. The mean follow-up was 19 months (12 to 26). Functional assessment using the modified Cincinatti and Stanmore scores and objective clinical assessment showed that 88% had excellent or good results after ACI compared with 69% after mosaicplasty. Arthroscopy at one year demonstrated excellent or good repairs in 82% after ACI and in 34% after mosaicplasty. All five patellar mosaicplasties failed. Our prospective, randomised, clinical trial has shown significant superiority of ACI over mosaicplasty for the repair of articular defects in the knee. The results for ACI are comparable with those in other studies, but those for mosaicplasty suggest that its continued use is of dubious value

We reviewed 23 patients who had had 25 Darrach procedures for traumatic or post-traumatic disorders of the wrist at a mean follow-up of 75.5 months (36 to 121). The mean age at the time of operation was 61.1 years (34 to 82). All patients were reviewed in person. Assessment included a history, a questionnaire on patient satisfaction and a detailed physical examination. Standardised radiographs of both wrists were taken with the patient’s hands in a resting position and during maximal grip. Convergence of the distal ulnar stump towards the distal radius during maximal grip (dynamic radio-ulnar convergence) was seen in 14 wrists including five with actual contact (dynamic radio-ulnar impingement), but this produced symptoms in only two cases. The presence of dynamic radio-ulnar convergence did not correlate with grip strength, pinch strength, range of movement or wrist score, but was associated with increased length of excision of the distal ulna. Nineteen of the 23 patients were satisfied with the procedure. Dynamic radio-ulnar convergence is common after the Darrach procedure, but is rarely symptomatic; resection of the distal ulna remains a reliable procedure in the older patient with pain and loss of movement. Excision of the lower end of the ulna should be restricted to the least required to restore full rotation

Evidence suggests that the alleviation of pain is enhancedby a strong patient-clinician relationship and attending to a patient’s social and mental health. There is a limited role for medication, opioids in particular.

Orthopaedic surgeons can use comprehensive biopsychosocial strategies to help people recover and can work with colleagues who have the appropriate expertise in order to maximize pain alleviation with optimal opioid stewardship.

Preparing patients for elective surgery and caring for them after unplanned injury or surgery can benefit from planned and practiced strategies based in communication science.

We evaluated changes in bone mineral density (BMD) after tibial fractures, both at the site of fracture and at adjacent sites, using dual-energy X-ray absorptiometry. Five patients were studied prospectively for six months after fractures of the midshaft treated by intramedullary nailing or the application of an external fixator. We also reviewed 21 adult and 10 children who had sustained fractures of the tibia at least five years previously, comparing BMD in the injured limb with that in the non-injured limb and in a control group of 10 normal subjects. We found a significant fall in BMD distal to a tibial fracture; this was evident at one month, fell to approximately 50% of normal at three months and persisted at six months. We found no significant improvement with weight-bearing. Review at 5 to 11 years after adult midshaft fractures showed persistent bone loss in the distal tibia (46.5 +/- 9.8% of control values), but persisting sclerosis at old fracture sites (172 +/- 38% of control values). In contrast, we found no significant differences in BMD between the injured and control limb after fractures sustained in childhood either at the fracture site or in the distal segment. We conclude that, in adults, tibial fractures are associated with definite and persistent post-traumatic loss of distal BMD

Between 1978 and 1986, 59 patients received a GSB III elbow prosthesis, six of them in both elbows. Rheumatoid arthritis (RA) was the underlying cause in 51 of the patients and post-traumatic osteoarthritis (PTOA) in eight. Of these, 24 patients (28 prostheses) have since died; two, both operated on bilaterally, had had their implants for more than ten years and had already been assessed for inclusion in the long-term follow-up. Two patients, each with one elbow prosthesis, have been lost to follow-up and three males who are still living (two with PTOA, one with juvenile RA) had their prosthesis removed before ten years had elapsed. The remaining 32 patients (28 RA, 4 PTOA) with 36 GSB III elbows were examined clinically and radiologically after a mean period of 13.5 years. Pain was considerably reduced in 91.6%. Mobility was increased by 37° in those with RA and by 67° in those with PTOA. There were three cases of aseptic loosening and three of deep infection. The main complication was disassembly of the prosthetic component in nine elbows (13.8%). This last group included two patients with postoperative fractures unrelated to the operative technique and one with neuropathic arthritis. Ulnar neuritis occurred in two patients. Since 87.7% of all the GSB III prostheses implanted in this period remained in situ, our results are comparable with those for hip and knee arthroplasty
