Scapholunate dissociation

Lateral view: Scapholunate angle >60 degrees. 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. as scapholunate (SL) dissociation in a cadaveric, biomechanical study. Methods.

It is caused by rupture of the ligaments between radius, … A scaphoid radiograph series, consistent with American College of Radiology guidelines, was obtained based upon examination findings. The radiographs revealed a scapholunate gap of 4 mm and a scapholunate angle of greater than 60°, suggestive of scapholunate dissociation.

Scapholunate (SL) instability is the most common dissociative carpal instability condition. 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 instability.

Scapholunate dissociation, also known as rotary subluxation of the scaphoid, refers to an abnormal orientation of the scaphoid relative to the lunate and implies 3 Jun 2014 Scapholunate dissociation (SLD) is the most common type of carpal instability. It is the most common instability pattern because the intercarpal greater than 2-5 mm as evidence of scapholunate dissociation.

Widening of the scapholunate joint space >3mm Known as Terry-Thomas sign (or David Letterman sign) Rotary subluxation of the scaphoid Lateral view: Scapholunate angle >60 degrees; PA view: Cortical ring sign (circular cortex of the bone is more prominent) Dorsal intercalated segment instability

Scapholunate dissociation. BAKGRUND Definition. Ruptur av det interosseösa ligamentet mellan scaphoideum och lunatum (SL-ligamentet), vilket medför att scaphoideum tippar volart och lunatum dorsalt. Epidemiologi. Vanligaste ligamentskadan i handleden som ofta förbises. 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 The increased distance indicates scapholunate dissociation.

This condition is known as “dorsal intercalated segmental instability” or “DISI” deformity. Scapholunate dissociation Power Point 1. 46yo male presents with chief complaint of left wrist pain.

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.

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 instability. Scapholunate dissociation.

It occurs due to injury to scapholunate interosseous ligament (SLIL). A medical illustration showing Scapholunate Dissociation. Scapholunate Dissociation - 603034-01XG.

Scapholunate dissociation, also known as rotary subluxation of the scaphoid, refers to an abnormal orientation of the scaphoid relative to the lunate, and implies severe injury to the scapholunate interosseous ligament and other stabilizing ligaments.

Info.

The authors conclude, “The ANAFAB procedure, although early in practice, shows promising results. It offers a robust restorative option for patients with acute or chronic scapholunate dissociation, characterized by scapholunate gap, scaphoid rotatory subluxation, DISI and dorsal scaphoid translation. 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.
