[57] ABSTRACT
A compression interlocking system for stabilizing long bone fractures, comprises an elongated intramedullary rod having a proximal end, a distal end and a longitudinal axis, the rod adapted for extending within a bore generally parallel to a longitudinal axis of a long bone from a proximal end of the bone to beyond a fracture of the bone, a first member for fixing the proximal end of the rod to a first portion of a bone having a fracture, a second member for fixing the distal end of the rod to a second portion of the bone having the fracture, and a cam associated with at least one of the first and second members for moving the first portion of the bone and the second portion of the bone toward one another for closing and applying compression to the fracture.
