Wrist instability is a common injury treated by many hand therapists. The anatomy of the wrist includes eight carpal bones that, with the combined efforts of the intercarpal ligaments, allow for circumduction of the wrist joint while imparting stability anywhere within the range of motion. An injury to one or several of the ligaments can lead to wrist instability.

The scapholunate (SL) ligament runs between the scaphoid and the lunate and provides crucial support to allow appropriate carpal mechanics at the wrist during motion and use of the hand. Injury and tearing of this ligament can occur with trauma or as a progressive degenerative weakening of the ligament. The extent of the injury ranges from a partial tear or attenuation to a full rupture of the ligament and from dynamic instability
