Ulnar shortening osteotomy (ulnocarpal impingement)
Ulnocarpal impingement involves excessive pressure between the distal end of the ulna and the wrist bones, causing pain on the ulnar side, particularly during rotational movements or when bearing weight. When medical treatment is no longer sufficient, an ulnar shortening osteotomy may be recommended.
The procedure involves removing a thin slice of bone from the ulna, then fixing the bone in place using a plate and screws to reduce the stress on the cartilage and the triangular fibrocartilage complex (TFCC). It is carried out under local anaesthesia, usually on an outpatient basis.
Following the operation, immobilisation is usually required for a few weeks before rehabilitation can begin. Bone healing usually takes 2 to 3 months. The aim is to provide long-term pain relief, preserve wrist function and enable a gradual return to normal activities. In rare cases, discomfort caused by the fixation may lead to its removal once the bone has fully healed.
