A computer-linked magnetic motion transducer was used to monitor and record the six components of motion of the bone fragments in eight cadaveric tibiae in which a simulated, oblique fracture of the middle of the shaft had been stabilized with a functional brace. The limbs were mounted in a servo-hydraulic testing frame, and a cyclic load of 150 newtons was(More)
The classic position of immobilization of Colles' fractures with the elbow in flexion, the forearm in pronation, and the wrist in volar flexion and ulnar deviation is probably the main reason for the common and rapid recurrence of the original deformity. Such a position places the brachioradialis muscle, a strong flexor of the elbow and the only muscle(More)
We reviewed the radiographs of 864 Charnley and STH (Zimmer) cemented total hip arthroplasties with a mean follow-up of seven years (maximum 16 years). Survivorship analysis was used to assess the correlation between radiographic performance and the bony containment or the coronal orientation of the acetabular cup. The cup orientation and containment were(More)
The effect of angular deformities of the tibial shaft on the area, location, and shape of the ankle joint contact during the normal extremes in the gait cycle was studied with the use of a cadaveric model. Six lower limbs were first examined radiographically and found to be free of pathology. These specimens were then stripped of soft tissues proximal to(More)
The authors report 40 cases of interfascicular nerve grafts carried out since 1976 on the main peripheral nerves: 10 grafts of the median nerve, 21 grafts of the ulnar nerve, 8 grafts of the radial nerve and 1 graft of the sciatic nerve. In all cases, these are secondary grafts: either or first intention when the nervous section has been observed in(More)
