An endomedullary nail for the treatment of proximal femur fractures, comprising an elongate body () having a proximal portion () and a distal portion (). The proximal portion () has a first and a second hole () for a respective cephalic screw (), each having a transversal axis to the axis of the proximal portion (). The first hole () is split into two passages each having a respective axis (A, B) with a predetermined angle relationship with respect to the axis (C) of the second hole (). The passages () are arranged to be selectively engaged by a respective cephalic screw ().

Endomedullary nail for the treatment of proximal femur fractures

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.

An external trochanter splint, especially for surgical stabilization of femoral pertrochanter and subtrochanter fractures, comprises a pair of clamps (2,3) each with its own longitudinal axis (a,b). One of these clamps (2) is designed for the movable locking of a first group of bone screws or bolts (V) inserted into the mass of the trochanter, the other (3) is designed for the movable locking of a second group of bone screws or bolts (W) inserted into the proximal diaphysis of the femur. The two clamps are connected together in side-by-side relation via an intermediate connecting member (4). First provision is made for immobilizing a selected angle of divergence (.alpha.) between the longitudinal axes (a,b) and second provision is made for immobilizing a selected angle of rotation of at least one of the said clamps (3) about its own longitudinal axis (b). Intermediate member (4) comprises a central body (21) connected to clamps (2,3) via a pair of rotatable joints with corresponding axes of rotation (c,d) which are substantially at right angles. In alternative embodiments, the bone screws or bolts of the clamp along the trochanter can be immobilized along convergent alignments; the joint between the two clamps has one or more frustoconical contact surfaces; and the clamp to the femur is subdivided into two parts which can be angularly oriented about the longitudinal axis of the clamp.
