Long-term Radiographic and Clinic Outcomes of Ulnar Shortening Osteotomy in Patients With Ulnar Impaction Syndrome and Reverse Oblique Sigmoid Notch

Patients with ulnar impingement are often coexisting with patients with distal ulnar and ulnar joints with a type of sigmoid notch, and ulnar shortening surgery is one of the most useful and long-lasting treatments for the treatment of ulnar impingement. Some theories point out that if ulnar shortening surgery is performed on patients with distal oblique ulnar incisional ulnar joints, it may lead to accelerated degeneration of distal ulna and ulna articular joints, resulting in worse wrist function. Some theories have pointed out this Instead, surgery will cause joint remodeling and adaptation, but no long-term studies have confirmed this. Therefore, this study plans to evaluate the long-term radiological and clinical outcomes of ulnar shortening surgery performed on patients with preexisting inverted sigmoid notch to determine whether this surgery will cause accelerated distal degeneration of the phalangeal joints or Reshaping of joints and clinically corresponding changes in results.
