Abstract
A device and method of stabilizing a fracture of a bone is provided. The device includes an intramedullary rod having a shaped distal end, and an insertion jig detachably connectable to the proximal end of the rod and used with the rod to apply a compressive force to the fracture site. The jig may also be used to correctly place fixation screws in a proximal end of the rod. The device achieves both fixation of the rod to the bone regardless of rod or bone diameter and allows for compression at the fracture site. In addition, fixation of the rod to the bone is accomplished without requiring a precise alignment of a distal end fixation screw. The device uses headless fixation screws, which, when in place, are disposed below cortical surface of bone, reducing damage to overlying soft tissues.
