Frayed ulno-triquetral and ulno-lunate ligaments as an arthroscopic sign of longstanding triquetro-lunate ligament rupture.

In patients with chronic wrist pain of more than 6 months duration, arthroscopy may reveal fraying of the ulno-triquetral and ulno-lunate ligaments. This can be a sign of longstanding triquetrolunate dissociation. We present a prospective study in which frayed ulno-triquetral (UT) and ulno-lunate (UL) ligaments were sought on wrist arthroscopy and correlated with longstanding triquetro-lunate (TL) rupture.
