Corrosion in Modular Revision Hip Stem Tapers - A Retrieval Analysis. [PDF]
J Orthop ResABSTRACT 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.

Predicting the steady state thickness of passive films in order to prevent degradations of implant [PDF]
, 2013 Some implants have approximately a lifetime of 15 years. The femoral stem, for example, should be made of 316L/316LN stainless steel. Fretting corrosion, friction under small displacements, should occur during human gait, due to repeated loadings and un ...

Orthopedic Implant Fretting Corrosion
Corrosion Reviews, 2003 Fretting corrosion occurs to some extent on all load bearing metallic orthopedic implants. Fretting of total hip and knee replacements occurs at such places as the bone-stem interface, the stem-cement interface, and on the interfaces of modular connections between implant components.
