title: Long-term results of silicone trapezial implant arthroplasty.
abstract: The senior author has performed the Swanson implant arthroplasty for arthritis of the basal joint of the thumb for the past 12 years. Fifty-two patients with a total of 64 arthroplasties of the thumb were reviewed, with follow-up periods of 12-156 months (average, 4.4 years). The majority (80%) of the arthroplasties were performed for osteoarthritis; 11% were performed for rheumatoid arthritis, 6% for traumatic arthritis, and 3% for mixed connective tissue disease. Subjective and objective hand functional measurements and radiographic examinations were performed in the majority of patients (77%). The overall results were good both subjectively and objectively. Although degenerative changes involving the implant occurred with increasing frequency as the follow-up period increased, these changes were not symptomatic in the majority of cases.
