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. This is apparent on plain static radiographs.

This is apparent on plain static radiographs. 2013-05-31 Scapholunate injury (or scapholunate dissociation, SLD) is one of the most common and significant ligament injury of the wrist. (another common wrist ligament tear is TFCC injury) It usually occurs when the wrist is twisted with loaded hyperextension and ulnar deviation (wrist moving towards little finger), such as falling onto an outstretched hand The Terry Thomas (or Madonna) sign is given to the increase in the scapholunate space identified on an AP radiograph. The increased distance indicates scapholunate dissociation. 3 article feature images from this case 16 public playlist includes this case 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 Rupture of the scapholunate ligament is the first event in any sequence of perilunar ligament ruptures. It is the most common pattern of wrist instability. Its characteristics are the dissociation of the scaphoid and the lunate, with flexion of the scaphoid, and extension of the lunate.

The scapholunate joint is essential to carpal function. A scapholunate dissociation (SLD), which progresses through several stages, finally ends as a perilunate dislocation. The injury can be completely ligamentous or can be a combined fracture and ligamentous injury. SLD is one of the most common types of carpal instability. Scapholunate dissociation (SLD) is the most common type of carpal instability. It is the most common instability pattern because the intercarpal motion during flexion and extension cross at the scapholunate interface. Another reason is that compression forces transmitted through the capitate has a tendency to separate the scaphoid and lunate.

Stage 1: AROM ;Stage 2: Isometrics ; Stage 3: Partial weight bearing  Lunotriquetral Dissociation.

It is the most common instability pattern because the intercarpal motion during flexion and extension cross at the scapholunate interface. Another reason is that compression forces transmitted through the capitate has a tendency to separate the scaphoid and lunate. 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.

Scapholunate (SL) dissociation is part of a spectrum of traumatic carpal bone instabilities and is defined as disruption of the ligamentous complex holding the scaphoid and lunate together.

The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two.

Scapholunate dissociation is a rotatory subluxation of the scaphoid with widening of the gap between the scaphoid and lunate.
