Abstract
A drill sleeve is provided for guiding a bone drill in alignment with the screw holes and drill guides. The drill sleeve includes a cylindrical body having a first end, a second end and a longitudinal axis extending therebetween. The cylindrical body includes a longitudinal bore therethrough that is sized for passage of a bone drill. The drill sleeve also includes a frictional retaining element for exerting a bearing force against the surface of the bone drill, such that the frictional retaining element may support at least the weight of the drill sleeve on the bone drill. The bone drill has graduated indicia, and a portion of the drill sleeve may be referenced relative to the indicia so as to be used as a depth gauge for determining the length of a drilled hole in order to select a screw fastener having the appropriate length.
