Abstract
A modular hip stem prosthesis including a hip stem with an integral, enlarged shoulder and a neck section mountable to the hip stem. The integral, enlarged shoulder is designed to closely conform to the metaphyseal region to securely mount the hip stem in the end of the femur. The enlarged, shoulder portion of the hip stem is also selectively configured to be fabricated as a separate element so as to allow one of a plurality of distal stems to be mounted to the enlarged shoulder to create the hip stem. The neck section readily adapts the hip stem prosthesis for repair and replacement of the components of the total hip replacement without requiring replacement of the hip stem.
