Scapholunate Ligament Injury & DISI - Hand - Orthobullets. Orthobullets.com scapholunate dissociation causes the scaphoid to flex palmar and the lunate to dorsiflex if left untreated the DISI deformity can progress into a SLAC wrist DISI deformity may also develop secondary to distal pole of the scaphoid excision for treatment of STT arthritis DISI is a form of carpal instability dissociative

Scapholunate dissociation is the most common cause of the wrist pain and instability and typically results from scapholunate interosseous ligament (SLIL) injury. Xray indicates scapholunate ligament instability when the scapholunate distance is more than 3 mm, which is called scapholunate dissociation. A static instability is generally readily visible, but a dynamic scapholunate instability can only be seen radiographically in certain wrist positions or under certain loading conditions, such as when clenching the wrist, or loading the wrist in ulnar Get help for your wrist injury: http://drbadia.com/contactus_eng.php This video illustrates an all arthroscopic technique for debridement and repair of a sc Scapholunate Ligament Injury & DISI - Hand - Orthobullets.

This diagnosis, however, is based on the assumption that scapholunate dissociation is caused only by trauma.

It is the most frequent cause of wrist osteoarthritis, defined as scapholunate advanced collapse or SLAC wrist. Familiarity with the SL ligament complex is required to understand the various features of SL in … scapholunate angle >60º: a sign of scapholunate ligament dissociation; capitolunate angle >30º: the capitate is displaced posteriorly compared to the distal radius; CT. On sagittal CT, the same findings as on plain radiograph are seen. MRI. On sagittal MRI 9, the same findings as on plain radiograph are seen. Disruption of the stout dorsal interosseous ligament is required for scapholunate dissociation to occur. Review more high-yield concepts about Scapholunate Ligament Injury & DISI on the most recent episode of The Orthobullets Podcast. Scapholunate dissociation is the most common cause of the wrist pain and instability and typically results from scapholunate interosseous ligament (SLIL) injury.

The patient was then sent to MRI. Stage I- Scapholunate dislocation noted on PA of wrist film with increased space between scaphoid and lunate; Stage II & III –Perilunate dislocations; Stage IV-Lunate dislocation; The main differentiating factor between perilunate and lunate dislocation is the lunate’s articulation with the radius. 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.

The diagnosis however is frequently missed initially.
