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.

Importantly, there is widening of the scapholunate distance (Terry Thomas sign) consistent with scapholunate dissociation. Scapholunate dissociation (SLD) is disruption of the ligamentous connection between the scaphoid and lunate (Figures 3). 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. 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.

It is caused by rupture of the ligaments between radius, … Scapholunate dissociation is the most common cause of the wrist pain and instability and typically results from scapholunate interosseous ligament (SLIL) injury.

Scapholunate dissociation is one of the most common forms of carpal instability, which is often overlooked and leads to associated morbidity. Early clinical and radiological presentation may be

Se hela listan på jaocr.org 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. 2013-05-31 · In scapholunate dissociation, the triquetrum extends the lunate as the counterbalancing by scaphoid is absent and the scaphoid is flexed.

Scapholunate dissociation is the most common carpal instability. pronation with associated lunate extension. The abnormal kinematics lead to a decrease in surface area contact at the radioscaphoid joint. This abnormal articulation causes an increased concentration of load, leading to the

Scapholunate Dissociation. Tomas A. A 52-year-old man sustained an injury to the right wrist following a fall into a push-up position.

Although "scapholunate dissociation" is a descriptive term, it is used synonymously with its primary pathophysiologic correlate, scapholunate interosseous ligament (SLIL) injury. Although injury to additional ligaments is present in scapholunate dissociation, the SLIL is the major target of surgical reconstruction. Dorsal intercalated segment instability (DISI) is a related carpal malalignment pattern whic… Scapholunate dissociation is when the small bones in the wrist (the scaphoid and the lunate) move excessively in relation to one another.

Dorsal intercalated segment instability (DISI) is a related carpal malalignment pattern whic… Scapholunate dissociation is when the small bones in the wrist (the scaphoid and the lunate) move excessively in relation to one another. Physiotherapy is an important part of scapholunate dissociation rehabilitation. How does scapholunate dissociation happen?

Lateral view: Scapholunate angle >60 degrees; PA view: Cortical ring sign (circular cortex of the bone is more prominent) Dorsal intercalated segment instability Dorsal angulation of lunate relative to radius resulting in capitolunate angle > 20° Seen as loss of the normal collinear arrangement of the capitate, lunate, and radius; Differential DISI (dorsal intercalated segmental instability) 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 In a nutshell, scapho-lunate dissociation is when these two bones are forced apart due to trauma. Normally they sit closely beside each other and are held in place by ligaments. In this injury, the two bones are spread apart and the ligament that holds them close together is torn. 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.
