Twenty-four patients who had degenerative arthritis of the lateral compartment of the knee that was associated with a valgus deformity and a superolateral tilt of the joint line were treated by distal femoral varus osteotomy. A surgical technique that was designed to produce a horizontal joint line and a tibiofemoral angle of zero degrees is described. At(More)
A prospective study of the Keller procedure for hallux valgus was carried out on 44 female patients (75 feet) with an average age of 66 years. The average follow-up was 31 months (range, 12-64 months). The operation was effective in improving symptoms (joint pain and bunion tenderness), cosmesis, function (footwear and level of activity) and in decreasing(More)
Fresh small osteochondral allografts were implanted in 108 patients. A clinical and histologic analysis was undertaken in 18 patients whose grafts failed and were excised. Twelve of these patients had evidence of viable hyaline cartilage despite adverse conditions. If careful attention is given to patient selection, age, appropriate timing for correction of(More)
Fourteen patients with 20 total hip joint replacements were studied for 14 painful prosthetic hips. Clinical examination, plain film radiographs and 99Tcm-MDP bone scans failed to differentiate between infection and mechanical loosening of a prosthesis. Sequential use of 99Tcm-MDP and 67Ga-citrate bone scans were performed in an attempt to discover(More)
A rapid and precise nerve fascicle identification method based on the enzymatic activity of choline acetyltransferase (choline acetylase, or ChAC) is described. Motor nerve facicles demonstrated significantly higher ChAC activity in comparison to sensory nerve facicles. Based on this difference in activity, matching of nerve fascicle cut ends is possible in(More)
An analysis is presented of 1763 consecutive injuries that occurred in the Ybrig region in Switzerland, a ski resort, during the 1976-1982 ski seasons. The study included all persons injured while skiing and treated at the emergency care facility at the base of the Ybrig region. Fractures were the most frequent injury. Over the years, a decrease in the(More)
Seven patients (nine hips) who suffered from coxa vara were treated by distal transfer of the greater trochanter. The operation eliminated or markedly diminished the preoperative Trendelenburg sign, thus improving gait. In three patients (four hips) operated upon at the aged of 9 and 12 years, the initial coxa vara was converted into an almost normal valgus(More)
The laser beam can be adapted for use as a surgical cutting instrument. It was chosen for this purpose in the extirpation of an osteoma of the skull. Its removal by conventional means was believed to be too dangerous, because of surrounding vascularity. The nature and properties of the beam and its surgical applications are discussed briefly.
