The lunotriquetral (LT) ligament is an intrinsic ligament of the wrist, more particular an interosseous carpal ligament which provide stability to the proximal carpal row. This ligament has a thin, horseshoe-shaped structure and can be divided into three parts: a dorsal, a proximal and a volar one.efinition. Lunotriquetral dissociation (LTD) is the second most common ligamentous cause of carpal instability and is classified by Mayo âs well-known Classification of Carpal instabilities as an example of dissociative carpal instability (CID).
