Partially porous bone implant keel

摘要

A method for removing a stem portion of an orthopedic implant from a bone comprises exposing an implanted orthopedic implant (12) having a body portion, a stem portion (16) interconnected to the body and a porous metal section (22) forming an interconnection between the body and the stem portion. A cutting tool is mounted on a holder connected to an exposed surface of the orthopedic implant. The porous section is aligned with the cutting tool mounted on the holder. The entire porous section is cut by moving the cutting tool therethrough in a direction transverse to the stem portion axis. The implant body portion is then removed and then the stem portion is removed from the bone. The cutting tool may be a saw or chisel which may be mounted on a guide fixed to the body portion.
