Product Description The ZMR Porous Revision Components offer a choice of proximal or extensive porous fixation options. These implants address varying degrees of bone loss and mismatch between the metaphyseal and diaphyseal regions. A variety of proximal body and distal stem combinations are available to address these issues while focusing on the goals of secure fixation and kinematic restoration. Porous Stem Options Straight and bowed porous stems are available in up to four stem lengths and up to 10 diameters to optimize patient fit. The porous stems are coated with plasma sprayed Tivanium® Alloy to allow for potential bone outgrowth.
