One-Component Revision of Failed Hip Resurfacing from Adverse Reaction to Metal Wear Debris

Pritchett, James W.

This study assessed the results of 90 one-component revisions for failed hip resurfacing due to adverse reaction to metal wear debris (76 acetabular, 14 femoral). Patients with a femoral head size 40–45 mm (n = 33) received a two-piece titanium meshed shell with a cross-linked polyethylene liner and patients with femoral head size 46–54 mm (n = 43) received metal-on-metal components. Patients with femoral head size >45 mm who wished a metal-polyethylene bearing received a dual mobility femoral prosthesis. The mean follow-up was 61 months and the procedure was successful in 97% of the patients. Three failures required re-revision; there was one deep infection. There were no dislocations. One-component revision is a reasonable alternative to revision to total hip arthroplasty.
