Arthroscopic Assisted Reconstruction of LT-Ligament: A Description of a New Technique.

Background  Injuries of the lunotrirquetral ligament (LT lig) could be part of an extensive carpal injury and are then often treated at the time of the injury. However, when an injury of the LT ligament occurs alone, the injury is often missed. Treatment of this injury has traditionally been by open surgery, such as reattachment of the LT ligament, ligament reconstruction, or arthrodesis of the LT joint. These procedures needed a large exposure to the carpus running the risk of damaging the external ligaments, the nerves important for proprioception, and the capsule with the potential of scarring and adhesions. Materials and Methods  We describe a novel arthroscopic assisted technique for reconstruction of the LT ligament. Using this less invasive technique, there is a possible advantage of lesser scarring and faster mobilization. Results  We have performed this technique in two patients with more than 30 months follow-up. They both have great improvement of the functional scores. Conclusion  The novel arthroscopic assisted technique for LT lig reconstruction is a technically demanding procedure; however, this obtains good clinical results with more than 30 months follow-up due to less exposure of the carpus. Level of Evidence  This is a Level IV, case series study. Thieme. All rights reserved.
