[Late results of surgical management of medial femoral neck fractures by spongiosa traction screws].

In 36 cases of medial fracture of the femoral neck percutaneous compression osteosynthesis by a specific traction-screw was carried out. During a 3-year follow up five femoral head necroses and three cases of non-union occurred. 28 patients showed good or excellent results. Comparison with results of AO-spongiosa screws and sliding-screw plate reveals no significant differences. Due to small additional operative trauma this percutaneous fixation technique is an appropriate alternative of osteosynthesis of medial fractures of the femoral neck, especially in polytraumatised patients and old patients with high operative risk.
