[Varus osteotomy in severe arthrosis of the hip--a long-term study (author's transl)].

141 hips were reviewed more than 10 years after operation. The average follow-up was 13.5 years. A close relationship between the pre-operative functional state and the final result was established. The improvement was due to a decrease of pain in most cases, especially severe ones. Mobility and walking ability were little changed. Some worsening of the condition of patients was noted at about the 10th post-operative year. The aetiology, the degree of dysplasia, or degree of displacement of the osteotomy, had little influence on the final result. The degree of post-operative hip congruence was unimportant. The best results were seen in excentrated hips with severe radiological involvement. It is concluded that varus osteotomy is a valuable procedure in severe arthrosis of the hip. The hazards of the procedure are small, and it is indicated in young or middle-aged patients.
