Abstract

Lunotriquetral (LT) ligament tear, usually in combination with an adjacent carpal ligament injury, can result in complete 
LT dissociation and VISI (Volarflexed Intercalated Segment Instability). Operative techniques for the management of 
instability are highly variable with many described in literature, although there is little evidence to demonstrate the 
superiority of one definitive therapeutic technique of repair and reconstruction. In this paper, we discuss our proposed 
technique for performing LT ligament repair using an augmented internal brace, which addresses triquetral extension 
and lunate flexion. The internal brace construct also provides biomechanical superiority as it includes the augmentation 
of the ligament and capsule repair. We use figures and references from our case example to demonstrate this technique.
Level of evidence: V
