The trauma cases scapholunate ligament ruptures, resulting in separation of lunate from scaphoid. It also causes the scaphoid to rotate dorsally. A gap of more than 3mm is pathognomonic for scapholunate dissociation. 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 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 deviation. Definition. Ruptur av det interosseösa ligamentet mellan scaphoideum och lunatum (SL-ligamentet), vilket medför att scaphoideum tippar volart och lunatum dorsalt.

Known as Terry-Thomas sign (or David Letterman sign) 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: 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.

Lateral view: Scapholunate angle >60 degrees. 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 advanced collapse (SLAC) Scapholunate Dissociation. There is increased distance of greater than 5 mm (black arrow) between the scaphoid (S) and the lunate (L) producing the so-called Terry Thomas or David Letterman sign.

PMID: Scapholunate dissociation is a rotatory subluxation of the scaphoid with widening of the gap between the scaphoid and lunate. It is caused by rupture of the ligaments between radius, scaphoid, lunate and capitate bones. The scaphoid has lost its stabilizing function as a bridge between the proximal … 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. Scapholunate dissociation is a rotatory subluxation of the scaphoid with widening of the gap between the scaphoid and lunate. It is caused by rupture of the ligaments between radius, scaphoid, lunate and capitate bones. The scapholunate joint is essential to carpal function. A scapholunate dissociation (SLD), which progresses through several stages, finally ends as a perilunate dislocation.

This is apparent on plain static radiographs. 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.

Scapho-lunate ligament is an important ligament that holds the scaphoid and lunate bones together. When ruptured it can cause pain and instability in the wrist in short term and degenerative arthritis in 5-10 years. The injury often results from a fall onto the outstretched hand or a forceful / violent twisting injury to the hand.

Wrick JD et al performed proximal row carpectomy for SLAC and were successful in preserving joint motion1. The treatment of scapholunate dissociation remains controversial. Although good to excellent results have been reported using a variety of surgical techniques, they have often not been confirmed by other authors. Limited wrist mobility and the likelihood that degenerative changes will progress appear to be inherent in most approaches.
