Treatment of subtrochanteric fractures of the femur: a study of intramedullary compression nailing

7be results of prospective treatment of 31 patients with subtrochanttic frartures using the Derby inkamedullay nail are presented. The nail design, plus cerchge wires in unstable uses, allows axial compression of the fracture, to give rigid jxation and k&-sharing betwem bone and nail. Twenty-seven patients were follow.4 up for an average of 21.7 monlhs. lhre were 110 mechanical failures of the nail, and all 2 7fiactures united, two in minimal varus. Relatively early mobilization of the patients with isokakd jkactures occurred.
