  • Title: Lunotriquetral injuries in the athlete.
    Author: Weiss LE, Taras JS, Sweet S, Osterman AL.
    Journal: Hand Clin; 2000 Aug; 16(3):433-8. PubMed ID: 10955216.
    Abstract:
    The athlete with an LT injury typically presents with ulnar-sided wrist pain after a high-energy impaction of the wrist. Reagan's LT ballottement test and Kleinman's shear test help the examiner identify these injuries. A thorough radiographic examination includes standard PA and lateral radiographs. Magnetic resonance imaging or arthrography can be performed, but the sensitivity of these imaging studies varies. The palmar portion of the LT interosseous ligament, dorsal radiocarpal ligament, and dorsal intercarpal ligament play the most significant roles in LT stability. Lunotriquetral injuries without instability respond well to immobilization. Arthroscopy is valuable in staging and determining treatment but requires a thorough radiocarpal and midcarpal examination. Acute LT injuries with instability are treated with arthroscopic-assisted reduction and pinning. If desired, this procedure can be incorporated with an open ligament repair through a volar approach. Chronic LT tears without instability can also be treated arthroscopically. Treatment of the chronic LT tear with instability depends on the degree of collapse. Treatment in the athlete includes ligament reconstruction with capsulodesis or, rarely, intercarpal LT arthrodesis.
