The ZMR Taper Revision Hip Prosthesis is designed to achieve secure distal fixation* in the femur using a sharply splined and tapered distal stem with a roughened Tivanium® Alloy surface. The tapered distal stem is designed to wedge into the femoral medullary canal, transferring axial and bending forces, while the splines are press-fit into bone to provide rotational stability. The roughened Tivanium Alloy surface allows bone ongrowth.1-3 The modular proximal bodies and distal stems provide many sizing options to help achieve anatomic restoration.
