Treatment of comminuted diaphyseal fractures of the femur using closed blocking intramedullary osteosynthesis

During 1996-2000 at the Department of Urgent Traumatology of Loco-Motor System (Scientific Research Institute of Emergency Care named after N.V. Sklifosovskiy) intramedullar osteosynthesis using AO/ASIF blocked pin was performed in 20 patients with comminuted femur fractures (21 fractures). This method gives stabile fixation of fragments that allows to stand up and walk using crutches on 5-10 days after operation. Mean term of load bearing restoration and moving extremity function was 4.5 months. One patient had delayed fragments consolidation. No complications such as suppuration, extremity shortening, angle and rotation deformity were observed.
