The results of 189 Brunswik total hip replacements, performed at the Orthopaedic Hospital of the Invalid Foundation, Helsinki, Finland, and followed up for 2-3 years, are presented. According to the modified system of Merle D'Aubigne & Postel excellent results were achieved in 11.1 per cent (21/189), good in 56.6 per cent (107/189) and fair in 27.5 per cent (52/189). The failure rate was 4.8 per cent (9/189) and consisted of four deep infections, four cases of aseptic loosening and one ...

Long-term results of the application of free autogenous fibular graft in the treatment of aggressive bone tumours of the distal end of the radius are presented. Six patients underwent radical resection of the tumour including the articular surface of the distal radius during the period 1969 to 1978, the average follow-up time being 5 years. In one case the tumour was low grade chondrosarcoma, in three cases a giant cell tumour grade two to three and in the remaining two a hemangioma. ...

A massive allografting of deep-frozen cadaver bone or hemi-joint was performed in 11 patients with tumours which were diagnosed as aggressive, low-grade malignancies. One patient died from a pre-existing hepatic insufficiency. The other 10 patients have been followed up from 1 to 8 years. These patients received two bone grafts and eight hemi-joint grafts around the knee joint. The operative procedure consisted of fixation of the graft by stable osteosynthesis, surrounding the graft-host ...

Over a period of 6 years (1960-65), 886 patients were operated on for herniated lumbar disc. In 1971, 695 of these patients (78.5 per cent) answered a questionnaire. The material was analysed with the aid of a computer. Persons in the age groups 30-39 (38 per cent) and 40-49 (34 per cent) were most prone to develop sciatica. At operation the distribution of positive findings was found to be 5.7 per cent at level L3-4, 58.3 per cent at L4-5 and 36 per cent at L5-S1. Myelography with a ...

We analysed 80 consecutive patients with postero-lateral spine fusion performed during the years 1972-1976. Thirty-seven were women and 43 men, the mean age being 30 (14-54) years. In 73 cases the fusion was performed because of spondylolysis and spondylolisthesis and in seven because of some other form of painful instability. Preoperatively, all patients had pain in normal activities and 63 at rest. At the 1-5-year follow-up, eight patients were pain-free, while 69 had stress pain and ...

Fourteen biopsies of cartilage and subchondral bone were taken from nine half-joint knee allografts 10 weeks to 8 years after the transplantation. Deep-frozen cadaver grafts were used to replace the defective half-joint after resection for bone tumour. The biopsies revealed a slow substitution of the dead grafted bone and cartilage. Subchondrally, signs of incorporation could be seen from 12 months on. The dead cartilage matrix degraded gradually and slow simultaneous regeneration was ...

A long-term follow-up study is presented of 162 patients who were treated for knee arthrosis with proximal tibial osteotomy,10 of whom had undergone a bilateral operation. The average follow-up time was 8 years. Pre-operatively, varus deformity was found in the knees of 117 patients; 45 of them had valgus knees. In 142 knees curved osteotomy was performed and wedge osteotomy in 30. At follow-up, 33% of the patients were found to have no pain. Significant longterm improvement was ...
