Abstract:

A drill guide for use in corticotomy procedures includes a head having a first end forming tines for penetrating and gripping the bone, a second end generally opposite the first end, and a plurality of drill guide passages extending between the first and second ends. The drill guide passages are arranged at different angles to permit a drill bit to bore into the cortex at different angles and different depths to form a circumferential region of weakened cortex. In use, the drill guide is positioned on the bone at a selected fracture site and a drill bit is operated through selected guide passages to bore into the cortex at the fracture site, thereby weakening a circumferential region of the cortex. Any remaining cortex is broken to complete the corticotomy procedure.
