title: Metacarpophalangeal joint arthroplasty in rheumatoid arthritis.
abstract: Although metacarpophalangeal joint arthroplasty is occasionally performed for joints affected by osteoarthritis, it is most often done in patients with rheumatoid arthritis. The metacarpophalangeal joint is critical for proper finger function but is the most common site of involvement in the rheumatoid hand. A thorough understanding of the anatomy, pathophysiology, and mechanics of the metacarpophalangeal joint is a prerequisite for the evaluation and treatment of patients requiring metacarpophalangeal arthroplasty. Silicone rubber implants are the most frequently used device for treatment of revised metacarpophalangeal arthroplasty. Follow-up studies show that this surgery improves function and deformity and achieves nearly uniform patient satisfaction.
