Abstract
A drill guide includes a window and graduated indicia corresponding to a scale provided along a side of the windows. A gauge for use therewith includes a handle, a shaft having a reference mark thereon, and an end portion. The end portion is slightly angled relative to the remainder of the shaft and is spring-like. The end portion includes a rounded tip which ensures that the gauge rides smoothly in and out of drilled bone and bore, and an angled upper catch that allows a user to retrieve the gauge without chipping bone.
