Intertrochanteric displacement osteotomy in the treatment of femoral neck fractures.

A total of 51 patients with displaced femoral neck fractures of Garden grade III or IV was treated by intertrochanteric displacement osteotomy. Of these, 42 patients had complete follow-up and 31 fractures (73.8%) united. The results were satisfactory in 66.6% and poor in 33.4%. The poor results were mainly due to non-union, chronic osteomyelitis and stiffness of the hip or knee. A high intertrochanteric osteotomy with adequate displacement is recommended in fresh, displaced femoral neck fractures.
