Abstract
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.
