Abstract
Scapholunate complex injuries are the most frequent lesions associated with distal radius fractures and the treatment algorithm according to the stage of the instability remains controversial. However, there is an admitted consensus around the necessary treatment of the associated high-grade instabilities. They occur frequently in young patients after high energy trauma, and not treated, they can lead to chronic wrist pain and eventually to scapholunate advanced collapse. The routine use of the arthroscopy provides an accurate intraoperative staging of the lesions and allows a tailored treatment depending on the severity of the scapholunate instability.
