title: X-ray changes after expanded polytetrafluoroethylene (Gore-Tex) interpositional arthroplasty.
abstract: Thirty-one patients with degenerative osteoarthritis at the trapeziometacarpal joint underwent 34 expanded polytetrafluoroethylene interpositional arthroplasties. The average follow-up period for the group of patients was 41 months (range, 15-82 months). Subjective results and objective measurements for the patients at the time of review were favorable. X-ray analysis, however, revealed a high incidence of osteolytic lesions associated with microparticulate degeneration consistent with reactive particulate synovitis. Owing to the unacceptably high rate of secondary osteolysis, the authors recommend that use of this material for trapeziometacarpal or pantrapezial arthroplasty be abandoned.
