Abstract
A surgical bone rasp includes a body having posterior, anterior, medial, and lateral surfaces. The medial surface includes a proximal curved portion shaped to extend substantially along a concave medial curve. The proximal curved portion includes a plurality of teeth. Each tooth in the plurality includes a tooth gullet wall, a tooth undercut, and a tooth land between the proximal and tooth undercuts. The tooth lands can be generally flat and can extend along the concave medial curve. The tooth gullet walls can be parallel to one another and can be angled to extend away from the body between a distal direction and a medial direction. The tooth undercuts can be parallel to one another, can be angled to extend away from the body in a medial direction, and can be equally spaced apart along the longitudinal axis.
