The role of wrist arthroscopy in the diagnosis and treatment of lunotriquetral joint injuries

摘要

An injury of the lunotriquetral ligament (LTL) and associated dysfunction of the lunotriquetral joint (LTJ) can be a common cause of ulnar-sided wrist pain. The carpal instability that develops from this ligamentous injury can pose a significant problem in regard to accurate diagnosis and subsequent appropriate therapeutic intervention. Wrist arthroscopy plays a critically important role in assessing ulnar-sided wrist pain in general and LTJ injuries in particular. This article describes the current approach to the diagnosis and treatment of LTJ injuries and the related use of wrist arthroscopy as the most important extension of our clinical examination, imaging studies, and therapeutic surgical tools.
