Retrieval Analysis of Neck-Stem Coupling in Modular Hip Prostheses.

Abstract

BACKGROUND Dual-taper modular stems have suffered from high revision rates caused by adverse local tissue reactions secondary to fretting and corrosion. We compared the fretting and corrosion behavior of a group of modular neck designs to that of a design that had been recalled for risks associated with fretting and corrosion at the modular neck junction… (More)
