Abstract
A bone fixation plate for fixation of fractures having a small terminal bone fragment, such as fractures of the lateral malleolus. The bone fixation plate includes an elongated body, and two hook members extending from a first end of the elongated body. Each hook member curves back upon a bottom surface of the elongated body, back towards a second end of the elongated body, and terminating in a pointed prong region. The elongated body includes a first region, a second region, and an angled region disposed between the first and second region. The prong region has a longitudinal axis that is substantially parallel to a longitudinal axis of the angled region of the elongated body of the bone plate. A double barreled drill guide and associated interchangeable cooperating inner drill guides and gauges are provided to facilitate the drilling of pilot holes in a terminal bone fragment for axial insertion of the pointed prong regions of the hook members.
