Patent ID: 7044978

Claim:
A femoral hip implant for a femoral canal, the femoral canal having a canal wall with anterior, posterior, medial, and lateral aspects and a longitudinal axis along the femoral canal from a proximal position near the hip joint to a distal position nearer the knee joint, the femoral hip implant comprising: a stem having a proximal end, a distal end, and a longitudinal axis extending therebetween, the stem having a polished and tapered exterior surface that permits the implant to subside distally into a cured cement mantel under load; a positioner, the positioner being removably engageable with the stem, the positioner including means for preventing the stem from rising proximally beyond a predetermined position by abutment of the stem against the positioner while permitting distal subsidence of the stem; and means for anchoring the means for preventing relative to a femoral canal, the positioner comprising a body including first and second members extending at an angle from one another, the means for preventing including the first member and the means for anchoring including the second member, the first member being positionable proximally over a portion of the stem while the second member is simultaneously positionable along the exterior surface of the stem between the stem and the canal wall, the second member being anchorable in a cement mantel between the stem and the canal wall; and a head mounted on the stem, the head being engageable with a pelvic portion of the hip joint to provide articulating joint function, the means for preventing the stem from rising being able to prevent the stem from rising while permitting the stem to subside during articulation of the joint in use by a patient.
