The Gamma nail was designed to treat unstable intertrochanteric and subtochanteric fractures with the theoretical advantages of a load-sharing compinent which could be implanted by a semi-closed procedure. We report a retrospective study of 27 unstable peritrochanteric fractures treated by the Gamma nail.

Gamma nail were implanted with an average duration of anesthesia of 84 minutes and little intra-operative bleeding by a semi-closed technique.

Complications were few, and clinically not implant except one case of femoral shaft fracture at the distal end of the nail which healed well fter treatment with Gamma nail and circlage wiring.
