• scapholunate dissociation: Stage II • + lunocapitate disruption: Stage III • + lunotriquetral disruption, "perilunate" Stage IV • lunate dislocated from lunate fossa (usually volar) • …

Stage II describes displacement of the carpus relative to the lunate. The lunocapitate articulation may be disrupted resulting in a dorsal perilunate dislocation, or in the case of concomitant scaphoid fracture, the wrist may undergo a transscaphoperilunate dislocation.

Scapholunate dissociation is the most common cause of the wrist pain and instability and typically results from scapholunate interosseous ligament (SLIL) injury.

Reduction and Association of the Scaphoid and the Lunate for Scapholunate Instability Joseph M. Lombardi James A. Wilkerson Melvin P. Rosenwasser DEFINITION Scapholunate instability occurs as a result of injury to the scapholunate interosseous ligament (SLIL) and represents the most common type of carpal instability. Instability can be categorized based on physical and radiographic findings.…

The three UVA Professor, Dr. Nicole Deal, presents a surgical technique for repair of a scapholunate ligament disruption.

Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation. A scapholunate torn ligament does not heal on its own.

The scapholunate ligament usually tears when there is a lot of stress put on the wrist. A common cause is a fall onto the hand. Typically, the ligament is injured when the wrist is bent backward or into an unusual position. Stage I involves scapholunate ligament dissociation or scaphoid fracture. Stage II describes displacement of the carpus relative to the lunate.
