[Long-term results of compression-osteosynthesis with three AO-screws for spongiosa in fractures of the femur-neck (author's transl)].
Between 1969 and 1978 in 42 patients fractures of the femur-neck were treated with three AO-screws for spongiosa (screws with a short thread). Late results in these patients are reported. The interval between operation and follow-up was in average 90 months. In no case pseudarthrosis had developed; the rate of necrosis of the femur head was 23.8%. The method is suitable in selected cases of medial fractures of the femur-neck, type I and II, and in lateral fractures, preferably in younger patients. The results in fractures of type III according to Pauwels show, that in advanced age these fractures should be treated with a partial or total prosthesis, because the rate of necrosis of the femur-head cannot be lowered.
