Patent

CA 2376652

An implant and method for replacement of the proximal portion of a femur, and specifically for replacement of the natural femoral head is provided. The implant includes a body member for insertion, in use, through the natural femoral neck and in substantial alignment therewith; a head member with a spherical portion for engagement with a natural or a prosthetic hip socket; a joining portion for joining the head member to the body member; and a rod for insertion, in use, through the transverse passage of the body member. The rod is designed such that it has a cross-sectional configuration that contacts the cortical surfaces in the bone and inhibits micro-motion within the bone. In addition, the transverse passage of the body member is configured to complement the configuration of the rod such that the need for stabilizing screws toward the distal end of the rod is eliminated when the implant is assembled within the patient.
