Subtrochanteric fractures of the femur.

A consecutive series of 103 patients with a subtrochanteric fracture were prospectively studied. Ten patients were treated non-operatively, whilst the other 93 had operative treatment. The overall fixation failure rate was 12 per cent with a re-operation rate of 6 per cent by 1 year. There were six (8 per cent) failures of fixation for the 74 fractures treated with the sliding hip screw. No method of fracture classification was demonstrated to be of value in predicting either the choice of treatment or the risk of fracture healing complications. Either intramedullary nailing or extramedullary fixation with a dynamic hip screw appear to give the best results for subtrochanteric fractures.
