Abstract
A combination of a bone fixation plate for fixation of fractures having a small terminal bone fragment, such as fractures of the distal radius and a holder/impactor for gripping the bone plate and for facilitating impacting the bone plate, with or without predrilled holes. The bone plate includes hook members 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 holder/impactor is securely attachable to the bone plate, and includes a striking surface and a distal surface contour overlying and resting adjacent an apex of the hook member. The tooth members of the hook plate are preferably sharpened at their tips and edges to facilitate their impaction.
