Treatment of multifragmentary fractures of the femur by indirect reduction (biological) and plate fixation

We present a retrospective review of the results of 43 multifragmentary femur fractures treated under the principle of indirect reduction (biological) and plate fixation. Fractures were caused by high-energy trauma in all patients. Sixteen were subtrochanteric, 14 diaphyseal and 13 supracondylar. There were 13 open fractures. In six of the patients with diaphyseal fractures, a plate wits inserted through isolated proximal and distal incisions only, deep to the vastus lateralis. None of the fractures was treated with bone graft. The mean follow-up time was 28.3 months. Union was achieved in 41 patients within a mean period of 4.25 months. There was delayed union in one patient (subtrochanteric), non-union ill two, infection in three, malunion in three, leg shortening in six and mild knee stiffness in seven. In eight patients with diaphyseal fractures in whom a single incision was performed, the average time for fracture healing was 4.14 months ill seven and non-union developed in one. In six patients with diaphyseal fractures, in whom proximal and distal incisions were performed, the average time for fracture healing was 4 months. There was no difference (P > 0.05) between single and double incision with reference to infection and time to union, but the indirect reduction methods must be meticulously implemented. The implants we used are cheaper and more easily Supplied than many others. The Success rate is high when the technique is correctly implemented. We believe that this is a treatment of choice ill Countries with low socioeconomic status, no efficient health insurance system and no intraoperative image intensification.
