Scapholunate and lunotriquetral injuries: arthroscopic and open management.

It has become clear that the stability of the scapholunate joint is not dependent wholly upon the scapholunate interosseous ligament but rather upon both primary and secondary stabilizers, which form a scapholunate ligament complex. Each case of scapholunate instability is unique and therefore should be treated with tissue-specific repairs, which may partly explain why a single procedure cannot successfully restore joint stability in every case. Not all lunotriquetral ligament tears are traumatic. The optimal treatment of symptomatic tears is still uncertain. Wrist arthroscopy has a pivotal role in both the assessment and treatment of these derangements.
