ZMR XL
A Multitude Of Options
The ZMR™ XL Revision Hip option is an extension of the
globally successful ZMR Revision Hip System and has been developed to
deal with the most challenging of revision hip surgeries. As with all
revision hip surgery, proximal support of the implant is desirable. The
ZMR XL option includes proximal body components in a variety of heights
for use with either a tapered or porous stem component to accommodate
individual patient anatomies.
Porous Stems
The ZMR XL Revision Porous Stem was designed to achieve initial stem stability through intimate bone/ prosthesis apposition. Stems are available in both bowed
and straight designs. The stem is coated with plasma sprayed Tivanium
® Ti-6Al-4V Alloy to allow for bone ingrowth and biological fixation.
Taper Stems
The ZMR XL Revision Taper Stem was designed to achieve distal fixation in the femur using a sharply splined and tapered distal stem with a roughened titanium 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 the bone to
provide rotational stability. The roughened Tivanium Ti-6Al-4V Alloy surface allows bone ongrowth.
