A device for use in connection with a bone, comprising a first surface and a second surface spaced apart from each other at a predetermined distance and angled relative to each other along a portion thereof. The device having a first ridge projecting from the first surface in a direction away from the second surface, the first ridge extending substantially along a length of the first surface, and a second ridge projecting from the second surface in a direction away from the first surface, the second ridge extending substantially along a length of the second surface in a direction substantially parallel to the first ridge. The device further includes a remote surface positioned more distant from the center of a bone, a proximate surface positioned more near the center of a bone, a fixed end surface, and a removable end surface extending in a first direction. The body of the device extends between the remote surface and the proximate surface in a medial-lateral direction and between the fixed end surface and the removable end surface in an anterior-posterior direction. A first score mark extends between the medial surface and the lateral surface in a direction substantially parallel to the direction of the removable end surface.
