Abstract
An intramedullary cavity nail for the treatment of proximal femoral fractures, comprises a solid elongate body with a proximal portion (2) having at least one transverse bore for accommodating a corresponding screw (9, 10) for stabilizing the femoral neck, the proximal portion being joined to a distal portion (3) having at least one distal bore (16) for accommodating at least one diaphysis screw for stabilizing the distal part of the femur. The proximal portion (2) has a substantially constant diameter (.phi..sub.p) adapted to be stably anchored in a relatively limited length bore of the femur for reducing blood losses, while said distal portion (3) has a substantially constant diameter (.phi..sub.d) which is less than that of said proximal portion, for ease of insertion in the medullary canal of the femur without any drilling. The proximal and distal portions (2, 3) are substantially rectilinear and form between themselves a predetermined deviation angle (.beta.) in a lateral plane. The proximal portion (2) has a pair of inclined bores (7, 8) adapted for accommodating respective cephalic screws (9, 10) for the fixing of the femoral head. A template (20) with provision for angularly keyed engagement to the proximal end of the nail, has alignment bores for stabilized guidance of drill bits with each of the respective transverse bores of the intramedullary nail.
