Failure of the hinge mechanism of a trispherical total wrist arthroplasty: A case report and review of the literature

Abstract

We report a patient with rheumatoid arthritis who developed late catastrophic failure of the hinge mechanism of her trispherical total wrist arthroplasty. This was associated with synovitis secondary to wear debris from Titanium, cement, and polyethylene which produced exuberant flexor and extensor tendon synovitis and median nerve compression.
