Corrosion in Modular Revision Hip Stem Tapers – A Retrieval Analysis

Journal of Orthopaedic Research, Volume 44, Issue 2, February 2026.
ABSTRACT In revision hip arthroplasty, modular stems enable intraoperative adjustment of the biomechanics of the hip to ensure a stable joint function even in complex anatomical cases. Modular stem junctions, however, carry the risk of junction degradation due to corrosive processes or even junction breakage.
