A distal femoral osteotomy system and method according to which an end segment is cut from the bone to be realigned and a wedge-shaped segment is cut from between the end segment and the remaining portion of the bone. The wedge-shaped segment is cut so that it has an angled surface substantially corresponding to the angle of malalignment. The wedge-shaped segment is discarded and the severed end segment is repositioned relative to the remaining portion of the bone at an angle corresponding to the angle of malalignment to realign the end segment and the remaining bone portion and correct for the malalignment. A compressive load is then established across the remaining bone portion and the end segment.

Distal femoral osteotomy system and method

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.
