ABSTRACT:
A hand-held drill jig is utilized to locate and maintain a central axis through a head and an associated neck of a femur enabling a blind hole to be drilled into the femoral head oriented to the central axis. The drill jig is adjustable to accommodate a broad range of sizes of femurs and can be readily attached to, then removed from, the femur. A positioning mechanism is provided to firmly engage both the outer peripheral surface of the femoral head and the femoral neck. This operation renders associated drill bushing immobile relative to the femur and orients its longitudinal axis with the central axis. A drill bit is then capable of being guided through the drill bushing and into cutting engagement with the femoral head.
