Periarticular distal radius fractures and complex ligamentous injury: The role of arthroscopic evaluation.

Abstract

Distal radius fractures are associated with a high incidence of concomitant soft tissue injuries, including lesions of the triangular fibrocartilage complex and intercarpal ligaments. While advanced imaging has allowed for greater identification of such tears, discerning which lesions pose a functional consequence remains a challenge for the hand surgeon. A review and guideline for arthroscopic evaluation of suspected combined injuries is presented. Arthroscopic evaluation of distal radius fractures provides several unique advantages in such instances. Articular reduction can be performed via direct visualization with improvement in step-off and gapping. Furthermore, ligamentous injuries and carpal alignment can be directly assessed and treated. Subtle features of combined ligamentous trauma may be overlooked in the presence of more obvious fracture patterns. Wrist arthroscopy allows not only for a gold-standard method of evaluating of these soft tissue injuries, but also a means of treatment.
