The in vivo linear and volumetric wear of hip resurfacing implants revised for pseudotumor.
BACKGROUND: Metal-on-metal arthroplasty-related pseudotumors can cause severe local destruction of bone and soft tissues. The cause of pseudotumors is unknown, although some authors have implicated metal wear debris. The aim of this study was to measure the location and magnitude of wear on resurfacing devices that were retrieved during revision procedures for pseudotumor (the pseudotumor group) and for other reasons (the control group). METHODS: We examined thirty-six hip-resurfacing implan...Expand abstract
