ABSTRACT:
A clamp for the femoral stem of a total hip replacement. The clamp engages a top surface of the stem and a portion of the femur to urge the stem into the femoral cavity during hardening of the cement. The clamp includes a stem having a ball on one end which is adapted to seat in a depression on the upper surface of the stem. In one embodiment, the depression is disposed on a collar extending from the stem. The other end of the clamp includes spikes or the like for engagement of the femur. Typically, a spring biases the ball toward the spike to urge the stem downwardly into the femoral cavity.
