TERMINOLOGY
Definitions
- Scapholunate (SL) ligament
- Between scaphoid and lunate, composed of dorsal and volar bands, thin central membrane
- Along with lunatotriquetral (LT) ligament, creates water-tight separation between radiocarpal and midcarpal joint
- Dorsal intercalated segment instability (DISI): Instability pattern related to SL tear, resulting in palmar tilt of scaphoid and dorsal tilt of lunate
- Extrinsic ligament tears typically also present
- Scapholunate advanced collapse (SLAC): Chronic instability leads to proximal migration of capitate between scaphoid and lunate, osteoarthritis
- Scapholunate (SL) ligament
