Abstract
A bone fixation plate for fixation of fractures having a small terminal bone fragment, such as fractures of the distal radius. The plate includes an elongated body, and two hook members extending from a first end of the elongated body. A contoured region is configured to approximate the surface contour of the distal radius proximate the volar rim, the dorsal rim, or the radial arm. Each hook member is configured to provide subchondral support to a distal bone fragment, without causing shortening of the fragment into the metaphyseal bone, and without providing a bending torque directed to the base of the plate. The tooth members of the hook plate are preferably sharpened at their tips and edges to facilitate their impaction. A holder/impactor for gripping the radial hook plate, and for further facilitating impacting of the hook plate without the need to pre-drill pilot holes, is also provided.
