Introduction: Scapholunate ligament injury is rare in children. Most of the cases Keywords: Scapholunate dissociation, extraosseous, reconstruction technique.
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.…
Correspondence Abhimanyu Ved Department of Trauma and Orthopaedics, Wrexham Maelor This pattern of ulnar translocation, in reality, represents a severe form of scapholunate dissociation and carries a worse prognosis. 19 Figure 19: T1-weighted coronal image demonstrates ulnar translocation of only the lunate (L) and triquetrum (T) bones [radsource.us] Scapholunate dissociation Power Point 1. 46yo male presents with chief complaint of left wrist pain. Patient slipped on side walk on sheet of ice and fell forward, landing on outstretched hand. This is known as “scapholunate dissociation.” The bones also rotate abnormally after SL ligament tears, with the scaphoid rotating forward, and the lunate rotating backwards. This condition is known as “dorsal intercalated segmental instability” or “DISI” deformity.
The abnormal kinematics lead to a decrease in surface area contact at the radioscaphoid joint. This abnormal articulation causes an increased concentration of load, leading to the In a nutshell, scapho-lunate dissociation is when these two bones are forced apart due to trauma. Normally they sit closely beside each other and are held in place by ligaments. In this injury, the two bones are spread apart and the ligament that holds them close together is torn. Scapholunate dissociation: Involves a complete tear of the SLIL with additional tear of 1 or more secondary ligaments. The scaphoid usually rotates into flexion, and the lunate rotates into extension.
Scapholunate advanced collapse (SLAC) is a type of arthritis related to scapholunate dissociation. Wrick JD et al performed proximal row carpectomy for SLAC and were successful in preserving joint motion1.

2013-05-31 · In scapholunate dissociation, the triquetrum extends the lunate as the counterbalancing by scaphoid is absent and the scaphoid is flexed. This leads to dorsiflexion of lunate, palmar flexion of scaphoid which will increase the scapholunate angle and lunocapitate angle creating the dorsal intercalated segment instability (DISI) pattern. The scapholunate joint is essential to carpal function.
