Abstract
During a twelve-year period, twenty-eight patients (thirty thumbs) were treated for painful idiopathic arthritis of the metacarpotrapezial joint of the thumb by fusion. Failure of fusion occurred in two thumbs, and in both instances a solid fusion followed a second procedure. Fusion of the metacarpotrapezial joint did not predispose to painful arthritis of the trapezioscaphoid joint, even in patients with pre-existing roentgenographic evidence of minor degenerative changes in this joint. The results after long-term follow-up were gratifying, the patients having painless and stable thumbs with excellent strength. Although patients noted a minor loss of thumb motion, they did not consider this a problem. Fusion is a satisfactory procedure for patients who need or desire a strong, painless thumb, and seems especially worth while in the dominant thumb when both thumbs require surgical treatment.
