Mechanical Evaluation of Posterior Wall Acetabular Facture Fixation: Patient‐Specific Implants Versus Conventional Implants

Journal of Orthopaedic Research, EarlyView.
ABSTRACT The aim of the study was to design a standardized mechanical test setup and a corresponding finite element analysis to assess the stability and strength of both patient‐specific and conventional implants for posterior wall acetabular fractures.

Corrosion in Modular Revision Hip Stem Tapers – A Retrieval Analysis

Journal of Orthopaedic Research, EarlyView.
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.

The Effect of Implant Size on Fretting Currents of Acetabular Cup‐Liner Tapers During in Vitro Cyclic Loading

Journal of Orthopaedic Research, EarlyView.
ABSTRACT As dual mobility hips become more popular, there is a clinical need to investigate design features that will impact tribocorrosion of these devices. While previous studies have investigated both corrosion and wear damage, the effect of device size on fretting corrosion response has yet to be evaluated. In this study, we compare two implants of
