title: Diagnosis and Treatment of Chronic Lunotriquetral Ligament Injuries.
abstract: Chronic lunotriquetral (LT) injuries are less common than scapholunate ligament injuries and difficult to diagnose. They may be associated with positive ulnar variance. Clinical diagnostic tests elicit pain at the LT interval. Although radiographs are typically normal, MRI and wrist arthroscopy can help confirm the diagnosis. When conservative treatments fail, surgical options include LT ligament reconstruction, LT arthrodesis, and ulnar-shortening osteotomy (in patients with positive ulnar variance).
