Completed

• Conditions: Wrist Arthritis; Wrist Osteoarthritis

• Registration Number: NCT05875896
• Lead Sponsor: Waldfriede Hospital

Brief Summary

The primary working hypothesis of this study is whether wrist arthrodesis leads to an improvement in functional status in both rheumatoid arthritis and 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.
