ABSTRACT:
Apparatus for fixing a fracture of a bone including an elongated body member having a proximal end and a distal end for insertion into the intramedullary canal of the bone; a tab member having at least one aperture to allow for passage of a screw for fastening of the tab member to the bone; and a bolt for selectively removably coupling the tab member to the proximal end of the body member. Preferably, the tab member is of a hollow cylindrical configuration and removably interlocking the first plate member to a second plate member. In another embodiment, the apparatus include a body member for insertion into a bone cavity, the body member having at least one aperture disposed in close proximity to its first end to allow for passage of a screw for fastening the body member to the bone. The present invention is also directed to apparatus for fixing a bone fracture including a first elongated plate member having at least one aperture so as to permit passage of a screw for attachment to the outer surface of a first portion of the bone. The first plate member has a first end and a second end and has a predetermined curvature so as to conform generally to the curvature of the first portion of the bone. The apparatus includes a second elongated plate member having a predetermined curvature so as to conform generally to the curvature of the second portion of the bone. A C-shaped channel is disposed on the first end of the first plate member for selectively removably interlocking the first plate member to the second plate member.
