Boutonniere rheumatoid thumb deformity.
The boutonniere deformity is the most common rheumatoid thumb deformity. It can be classified into early, moderate, and advanced types, depending on whether the deformity is passively correctable. Fifty-three patients with 74 procedures form the basis of these recommendations. The early type treated with metacarpophalangeal joint synovectomy and extensor pollicis longus rerouting have a high recurrence rate of 64%. Metacarpophalangeal joint fusion is the procedure of choice for the moderate type with isolated metacarpophalangeal joint involvement. Metacarpophalangeal joint arthroplasty is best suited for the low-demand, older patients with borderline proximal and distal joints. Interphalangeal joint releases done with metacarpophalangeal joint fusions have a high recurrence rate and are not recommended. In advanced cases metacarpophalangeal joint arthroplasty and interphalangeal joint fusion is our procedure of choice.
