Adverse Local Tissue Reaction due to Acetabular Corrosion in Modular Dual-Mobility Constructs.


ABSTRACT: Dual-mobility (DM) bearings in total hip arthroplasty (THA) have been reported to reduce dislocation rates, especially in high-risk patients, and are being rapidly adopted in primary and revision THAs. However, this technology introduces additional interfaces that have the potential to result in unforeseen complications. We present a series of 3 patients with mechanically assisted crevice corrosion at the acetabular component-metal dual-mobility liner interface. Consequently, we urge judicious use and close clinical observation of this new, effective technology in THA.
