A study of plantar flexion strength and calf circumference in 30 conscripts is submitted. It showed an asymmetry of strength amounting to 6--11 per cent (95 per cent confidence limits). The right leg was significantly stronger than the left, but there was no difference in strength between the dominant and non-dominant leg. There was little correlation(More)
Out of 174 patients treated conservatively for injuries to the lateral ligaments of the ankle 144 were seen at follow-up after 3.1--6.1 years (mean 4.2 years), and clinical as well as social sequelae were recorded. The diagnostic criterion was a difference in talar tilt of 6 or more degrees between the injured and uninjured foot on inversion stress(More)
An average of 4.2 years after conservative treatment of injury to the lateral ligaments of the ankle 144 patients attended a follow-up examination which included radiography and measurement of the strength of plantar flexion. Prior to treatment all of the patients had a difference in talar tilt of 6 or more degrees between the injured and uninjured side. At(More)
Seventeen patients with arthrosis secondary to congenital dislocation or dysplasia of the hip were treated by total hip replacement. Nine hips were completely dislocated, while 12 were dysplastic and subluxated. The operation was performed as a modification of Charnley's standard technique, the acetabular prosthesis was always placed in the neoacetabulum,(More)
In a prospective, randomized study a comparison was made of the results of primary below-knee amputation for ischaemic gangrene carried out by two methods: In 47 cases by the transverse technique with a long posterior musculo-cutaneous flap and in 41 cases by the sagittal technique using equally large medial and lateral musculo-cutaneous flaps--in both(More)
A modified Watson-Jones technique, using only half of the peroneus brevis tendon, was applied as an operative procedure for lateral ankle instability. Twenty-nine patients with 30 operated ankles were examined with an average follow-up period of 7 years and 6 months. Functional stability was achieved in all but one of the operated ankles. In 15 cases there(More)
To elucidate the long-term effect of osteotomy upon the intraosseous pressure in osteoarthritis of the hip, pressure measurements in the femoral head and greater trochanter were performed in 22 patients before intertrochanteric osteotomy and 11.5-33.5 months later, on the occasion of removing the osteosynthesis material after the osteotomy had healed.(More)
The intraosseous pressure of the femoral head and greater trochanter was measured during 146 Charnley hip replacement operations. In 108 hips with primary osteoarthritis the pressure in the femoral head averaged 49.6 and in the greater trochanter 31.6 mmHg. The pressures in the greater trochanter were significantly lower than those in the femoral head.(More)
