Abstract
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.
