The Scaphoid and Lunate bones are conjoined through an intra-articular ligament known as the Scapholunate. This ligament is responsible for coordinated movement of the lunate and scaphoid bones facilitating smooth rotation of the wrist1. For surgical treatment, small joint anchors can be used to repair or reconstruct the scapholunate joint upon tearing.
