Joint Fusion and Arthroplasty in the Hand.

Numerous techniques are available for treating finger joint disorders such as osteoarthritis and inflammatory arthritis. Joint fusion and arthroplasty have different concepts but can improve hand function. Joint fusion is indicated in patients with painful finger joints with or without poor soft tissue condition. Implant arthroplasty is indicated for degenerative or inflammatory arthritis in elderly patients because implants may require future revision. Arthroplasty with an autologous osteochondral cartilage graft is an option for young patients with posttraumatic metacarpophalangeal or proximal interphalangeal joint osteoarthritis, whereas vascular joint transfers are rarely used. Surgeons must carefully check each patient's condition and treatment expectations.
