Abstract: A nail (or rod) for axial insertion into a large bone for support thereof, which comprises an elongated nail body having a central bore extending through the nail body from the proximal end along a proximal portion of the nail, and typically terminating at point spaced between the ends. The nail may also define a transversely flattened distal portion extending proximally from the distal end. In the embodiment shown, an open slot may extend centrally and longitudinally from the distal end along the distal portion to an inner slot end which is spaced between the ends of the nail. The nail body defines a plurality of transverse holes extending therethrough for receiving bone screws for supporting securance of the nail to a bone while the nail occupies the intramedullar space of the bone.

Abstract: An intramedullary rod having a cylindrical proximal portion and a rectangular distal portion has a tapering blade-like portion. The intramedullary rod provides rotational stability and resistance to axial migration. Proximal and distal transfixation holes may be provided in the intramedullary rod.
