title: Porous pad separation and loosening of Harris-Galante femoral hip components.
abstract: Failure of the bond between the metal beads and the solid substrate of porous-coated chrome-cobalt femoral components, or so-called "bead shedding," has been reported previously and may indicate motion of the component within the femur or mechanical loosening of the prosthesis. Failure of the bond between a sintered titanium fibermesh pad and a titanium alloy femoral stem has not been documented in the literature to date. The separation of fibermesh pads from three Harris-Galante femoral prostheses (Zimmer, Warsaw, IN) is reported.
