Abstract

The present invention comprises an elongated bone fixation plate with a center portion which bridges the fracture site. The central portion has a square cross-sectional shape. Two oppositely directed end portions extend axially from the central portion. The central portion has a width which is substantially less than the width of the end portions of the bone fixation plate. The end portions of the bone fixation plate have a plurality of elongated holes and each end portion tapers in thickness from adjacent the central portion to the outer terminating ends of the fixation plate. The plurality of holes are elongated in nature with each hole having a vertical distal wall and an inclined proximal end wall sloping toward the vertical distal wall. Each end portion has a uniform width and the entire bottom surface of each end portion may be concave in shape so as to provide a complementary mating surface with the fractured bone. By employing cortical or cancellous bone screws having a head whose bottom surface is rounded, the bone fixation plate draws each bone piece toward one another and places the bone pieces in compression at the fracture site when the plate and screws are fully secured to the bone.
