The primary working hypothesis of this study is whether KeriFlex® metacarpophalangeal joint prostheses provide an equivalent result to Swanson finger joint implants in patients with rheumatoid arthritis or post-traumatic osteoarthritis. Functional status will be measured by Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire no earlier than 1 year after surgery.
