The axial alignment on short and long radiographs was measured in 50 knees in 34 patients who had undergone posteriorly stabilised (Insall-Burstein) condylar knee arthroplasty. A mean difference of 1.6 degrees was found when the tibiofemoral angles were compared on short and long radiographs. Short radiographs are probably adequate for routine assessment of(More)
We reviewed the results of 22 operations performed on 21 patients for the relief of de Quervain's disease over the last six years. At a mean follow-up of 34 months (range 4-78 months), 18 of 22 wrists had complete relief of their original symptoms. One patient required reoperation because of inadequate decompression, and two others await further surgery.(More)
8 subjects with a variety of orthopedic implants were examined by the security staff at an international airport using arch and hand-held metal detectors. None of the subjects caused activation of the alarm on the arch, although the presence of metal was registered in 2 at a level below the alarm threshold. The hand-held detectors alarmed over the larger(More)
In osteoporosis it is postulated that while the amount of bone is diminished, the quality of the bone is unaltered. Recently relatively novel methods of analysis have shown that, at the fracture site of osteoporotic subcapital fractures, there is a marked change in the molecular orientation of components of the non-collagenous bone matrix. These procedures,(More)
Twenty patients with Colles' fractures were treated with a functional brace that allows wrist motion. The result was compared with a similar group of patients treated with a plaster cast. Dorsal displacement of the fracture was less and wrist function was better in the brace group. Swelling of the hand during the early stages was observed in the brace(More)
Twenty patients with acromioclavicular dislocations treated by transfer of the coracoid process to the clavicle were reviewed and were compared to a previous study. Surgery was performed for acute dislocations in seven cases and for chronic dislocations in 13 cases. At the follow-up examination (5.6 +/- 3.5 years for acute and 4.0 +/- 3.6 years for chronic(More)
We studied the morphology of the contralateral femur in 10 patients with subcapital fractures, 10 with trochanteric fractures and 10 with unilateral osteoarthritis. We found that the patients with trochanteric fractures had a significantly shorter femoral neck (4.5 +/- 0.5 cm) than patients with subcapital fractures or osteoarthritis (5.4 +/- 0.4 cm). It(More)
Some 1000 postcard questionnaires were sent to Fellows of the British Orthopaedic Association (BOA) to establish current follow-up practice of primary total hip replacement (THR) patients. For cemented THRs, 50% of surgeons saw their patients for under 1 year, 78% under 5 years with indefinite follow-up being performed by 14%. There was significantly more(More)
