▶ Untreated ulnar collateral ligament (UCL) injury of the thumb metacarpophalangeal joint (MCPJ) can lead to longterm pain and functional limitations. ▶ Detection of a UCL injury involves sequential examination of true and accessory ligaments and comparison with the uninjured side. ▶ Acute partial UCL injuries can be successfully treated nonoperatively. ▶ Acute complete or displaced UCL injuries can be successfully treated with operative repair. ▶ In cases of chronic UCL injury, treatment options include static and dynamic reconstructions. ▶ If painful arthrosis is present with chronic UCL instability, salvage may be performed with MCPJ fusion.
