Metacarpophalangeal Joint

A healthy 25-year-old man presented with worsening pain and swelling over the ring finger metacarpophalangeal joint and mild scissoring of the index finger 11 months after a procedure for a circular saw injury on the left hand.

BOSTON — Long-term results showed significantly stronger pinch strength after patients with metacarpophalangeal arthritis underwent carpometacarpal arthroplasty with metacarpophalangeal fusion vs. carpometacarpal arthroplasty alone.

Published results showed radiographic metacarpophalangeal osteoarthritis was associated with mechanical factors and was especially associated with severe radiographic proximal interphalangeal joint OA.
