title: Interface corrosion of a modular head total hip prosthesis.
abstract: Wear and corrosion products released from metallic prosthetic joints can stimulate adverse reactions in the surrounding tissues that may eventually require revision of the prostheses. The authors report here a case of a modular total hip prosthesis removed after 35 months that showed evidence of corrosion and fretting at the Morse taper interface between the titanium alloy femoral stem and the cobalt-chromium ball.
