The outcome of bone graft surgery for nonunion of fractures of the scaphoid.

The Outcome of Revision Surgery for Failed Metal-on-Metal Total Hip Arthroplasty.

Background: Metal-on-metal total hip arthroplasties (MoM THAs) are frequently revised, though there is a paucity of functional outcome data. We report on outcomes and prognostic factors predictive of outcome from the largest series of MoM THA revisions to date.

Methods: A single-center consecutive series of revisions from MoM THAs was identified.
