Boutonniere finger deformities occur frequently in patients with rheumatoid arthritis. The deformity consists of flexion of the proximal interphalangeal joint and hyperextension of the distal interphalangeal joint. Treatment decisions are based on the degree of joint deformity, joint motion, passive joint correctability, and the status of the articular surface. Treatment options can then be based on the classification of the deformity; options consist of corrective splinting, injections, synovectomy, terminal tenotomy, extensor reconstruction, or salvage surgery (arthrodesis or arthroplasty).
