Salvage of Monoblock Metal-on-Metal Acetabular Components Using a Dual-Mobility Bearing

摘要

Background: Large-diameter, monoblock acetabular components have been used for both hip resurfacing arthroplasty and metal-on-metal (MoM) total hip arthroplasty (THA). If revision is required, one solution is to retain the shell and use a dual-mobility bearing.
