Front-to-Back Arthroscopic Repair of Complete Lunotriquetral Ligament Injuries: A Case Presentation and Algorithm for Arthroscopic Management of Intercarpal Ligament Injuries.
J Hand Surg Am
December 2024
Division of Hand and Upper Extremity Surgery, Department of Orthopaedic Surgery, Emory University, Atlanta, GA. Electronic address:
The lunotriquetral intercarpal ligament (LTIL) is an important structure that equalizes the forces on the lunate imparted through the scapholunate intercarpal ligament. The extension moment of the triquetrum balances the flexion force of the scaphoid, positioning the lunate for efficient load transfer from the hand to the wrist. In contrast to the scapholunate intercarpal ligament, the LTIL is strongest volarly, with the most critical region being associated with the volar ulnocapitate ligament.

Purpose Of Review: The standard of care for lunotriquetral ligament injuries is evolving. An understanding of the mechanics of the lunotriquetral ligament and its role in carpal kinematics is critical when deciding how to treat these injuries. Treatment for these injuries varies from nonoperative to wrist arthroscopy with thermal capsulodesis and/or repair to reconstruction or limited arthrodesis.

Lunotriquetral (LT) ligament injuries are uncommon, however, should be considered in patients with ulnar-sided wrist pain. LT injuries are often associated with other injuries but can occur in isolation. Understanding the anatomy and pathomechanics will aid in making the diagnosis.

Rationale: The goals of surgical treatment of the perilunate dislocation (PLD) are confirmation of reduction, ligament repair, and supplemental fixation of the bony architecture. Open reduction and direct repair of the torn ligament are recommended for acute PLD. However, repair of the scapholunate interosseous ligament (SLIL) and lunotriquetral interosseous ligament (LTIL) is often unreliable, and secure repair is challenging.

Rupture to wrist ligaments predisposes the joint to degenerative changes. Scapholunate interosseous ligament (SLIL) rupture, especially when compounded by dorsal intercarpal ligament (DIC) and long radiolunate ligament (LRL) disruption, can cause carpal bone kinematic abnormalities. It is essential to delineate the role of these ligaments and their constraints on wrist range-of-motion (ROM) and center of rotation (COR).
