One hundred and eighty-three conservative amputations of some part of the foot in 161 patients with gangrene from diabetes or arteriosclerosis have been studied retrospectively. They constituted 48 per cent of all amputations in one
Between 1980 and 1988, displacement bone-marrow transplantation was performed on 25 children with Hurler's syndrome (type-1 mucopolysaccharidosis). We describe the musculoskeletal development of 11 of the 12 surviving children and the
1. Analysis of the static and dynamic conditions in spastic cerebral palsy leads to the conclusion that contractures of the hip, knee and ankle should be released from above downwards, and that the full benefit is obtained only when all contractures have been corrected. 2. Only when these joints are mobilised by removal of the significant contractures is the spastic patient able, despite other handicaps, to sit, stand and walk with the least hindrance and the least cosmetic fault. 3. In our Danish experience, inadequate or poor results from the
Robotic-assisted total knee arthroplasty (RA-TKA) has been introduced to provide accurate bone cuts and help achieve the target knee alignment, along with symmetric gap balancing. The purpose of this study was to determine if any early clinical benefits could be realized following TKA using robotic-assisted technology. In all, 140 consecutive patients undergoing RA-TKA and 127 consecutive patients undergoing conventional TKA with minimum six-week follow-up were reviewed. Differences in visual analogue scores (VAS) for pain at rest and with activity, postoperative opiate usage, and length of stay (LOS) between the RA-TKA and conventional TKA groups were compared.Aims

Few risk factors for rotator cuff disease (RCD) and corresponding treatment have been firmly established. The aim of this study was to evaluate the relationship between numerous risk factors and the incidence of surgery for RCD in a large cohort. A population-based cohort of people aged between 40 and 69 years in the UK (the UK Biobank) was studied. People who underwent surgery for RCD were identified through a link with NHS inpatient records covering a mean of eight years after enrolment. Multivariate Cox proportional hazards regression was used to calculate hazard ratios (HRs) as estimates of associations with surgery for RCD accounting for confounders. The risk factors which were considered included age, sex, race, education, Townsend deprivation index, body mass index (BMI), occupational demands, and exposure to smoking.Aims

We performed an epidemiological analysis of 523 fractures treated in the Edinburgh Orthopaedic Trauma Unit over a three-year period using modern descriptive criteria. The fractures were defined in terms of their AO morphology and their degree of comminution, location and cause. Closed fractures were classified using the Tscherne grading system and open fractures according to the Gustilo classification. Further analysis of fractures caused by road-traffic accidents and football was carried out. The use of the AO classification allowed the common fracture patterns to be defined. Correlation of the classification systems showed an association between the AO morphological system and the Tscherne and Gustilo classifications. The relative rarity of severe tibial fractures is indicated and it is suggested that in smaller

Glass ionomer cement (Ionocem) was developed for use in bone surgery and is reported to be notably biocompatible. Between 1991 and 1994 we performed revision operations for aseptic loosening of arthroplasties of the hip on 45 patients using this material in its granulate form (Ionogran) mixed with homologous bone as a bone substitute. Of these 45 patients, 42 were followed up for a mean of 42 months. Early reloosening of the acetabular component has occurred in ten after a mean of 30 months. Histological examination showed large deposits of aluminium in the adjacent connective tissue and bone. Osteoblastic function and bone mineralisation were clearly inhibited. The serum levels of aluminium were also increased. The toxic damage at the bone interface caused by high local levels of aluminium must be seen as an important factor in the high rate of early reloosening. Our findings cast doubt on the biocompatibility of this material and we do not recommend continuation of its further use in
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

The organisation of accident services must be undertaken by the state as a quasi-military operation. To provide the whole country with integrated accident services on the lines suggested in this memorandum will clearly mean the expenditure of considerable sums of money over many years. Nevertheless, a beginning must be made; and the British
In a prospective study conducted between 1990 and 1997, 24 101 newborn infants were examined for neonatal instability of the hip and classified by the ethnic origin of their parents. In 63% their mother and father were of Swedish extraction and in 24% they were born in a foreign country. Those of foreign extraction were split into ethnic and geographical subgroups. Although the incidence of treated (dislocatable-unstable) hips was greater in Swedes (7.6‰), than in other geographical groups (5.8‰) it was not significantly different (p = 0.065). A total of 12.7‰ were referred from the neonatal ward to the
Postoperative deep-vein thrombosis (DVT) is believed to be rare in Asians. We studied 88 consecutive patients in Malaysia who had operations for fracture of the proximal femur or for total hip or knee replacement. No patient had prophylaxis against DVT; bilateral ascending venography was performed between six and ten days after operation. A total of 55 patients (62.5%) showed venographic evidence of DVT. The prevalence was greatest after total knee replacement (76.5%), less after total hip replacement (64.3%) and smallest in the fracture group (50%). One patient developed symptomatic pulmonary embolism. In contrast to other reports from Asia, we found an incidence of postoperative DVT which is similar to that reported in Western populations. This suggests that the present practice of withholding routine prophylaxis against thromboembolism in Asian patients undergoing high-risk
We treated 31 intra-articular fractures of the distal radius by arthroscopically-assisted reduction and percutaneous fixation with Kirschner (K-) wires. Tears of the triangular fibrocartilage (58%), scapholunate (85%) and lunotriquetral (61%) instability and osteochondral lesions (19%) were also treated. A total of 26 patients was independently reviewed at an average of 19 months. The mean pain score was 1.3/10, the range of movement 79% and the grip strength 90% of the contralateral wrist. Using the New York

In ten male rats we inserted ceramic ‘drawing-pin’ implants in weight-bearing positions within the right proximal tibia. Two animals were killed 6 weeks after surgery and two more 14 weeks after surgery. The remaining six received intra-articular injections of either high-density polyethylene (4 rats) or saline (2 rats) at 8, 10 and 12 weeks after surgery. These animals were killed two weeks after the last injection. Histological examination of the bone-implant interface in the control animals showed appositional bone growth around the implant at both 6 and 14 weeks. Polyethylene, but not saline, caused a chronic inflammatory response with numerous foreign-body giant cells in periprosthetic tissues. Our model of a stable, weight-bearing bone-implant interface provides a simple and reliable system in which to study in vivo the effects of particulate materials used in
