Lunotriquetral instability: clinical findings

摘要

Isolated injuries of the lumotriquetral (LT) interosseous ligament are a well-recognized cause of ulnar-sided wrist pain. Distinguishing this injury from other causes of ulnar-sided wrist pain can be difficult. The spectrum of LT ligament pathology ranges from partial tears with variable wrist pain and weakness to complete separation of the lunate and triquetrum with sag of the ulnar carpus. A thorough clinical examination with supportive imaging studies allows for an accurate diagnosis and provides information as to the extent of the injury.
