One specific wrist injury that can occur after falling on an outstretched hand is called scapho-lunate dissociation. A person who experiences pain in the back of the wrist or the thumb side of the wrist (following a fall) should be examined for scapho-lunate dissociation. Scapholunate Ligament Tear Signs, Symptoms and Treatment What is Scapho-lunate ligament injury? The wrist is complex joint consisting of 8 small bones, connected to each other with many strong ligaments. Scapholunate advanced collapse (SLAC) is a type of arthritis related to scapholunate dissociation. Wrick JD et al performed proximal row carpectomy for SLAC and were successful in preserving joint motion1.

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. For these same photos without the arrows, click here For more information, click on the link if you see this icon 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.

Familiarity with the SL ligament complex is required to understand the various features of SL instability. 1.Scapholunate dissociation results from the scapholunate ligament disruption/ injury with more important dorsal component, 3 mm thick (short, transversely oriented collagen fibers)/ volar component (1mm thick),intermediate component (fibrocartilage) meniscus shape 2.

The radiographs of the patients May 23, 2014 Carpal instability with some of its clinical manifestations had been described by Destot [16] in 1926, but the term „instability” was introduced by Diagnosis[edit] · Static scapholunate dissociation · Dynamic instability: Increased scapholunate distance (between yellow lines) upon ulnar deviation of the wrist, but Mar 1, 2019 Scapholunate (SL) dissociation is part of a spectrum of traumatic carpal bone instabilities and is defined as disruption of the ligamentous complex Carpal bones - Perilunate - Scapholunate dissociation - Ligament repair. Its characteristics are the dissociation of the scaphoid and the lunate, with flexion of the Oct 26, 2020 Any disruption to the anatomy impacts on hand function leading to pain, weakness and arthritis. Scapholunate dissociation is one of the most This indicates scapholunate dissociation, DISI deformity, and a functionally significant underlying scapholunate ligament injury (6a,7a).

Instability can be categorized based on physical and radiographic findings. Static instability: abnormal alignment of the scaphoid and lunate evident on routine radiographs 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.

Familiarity with the SL ligament complex is required to understand the various features of SL instability. 1.Scapholunate dissociation results from the scapholunate ligament disruption/ injury with more important dorsal component, 3 mm thick (short, transversely oriented collagen fibers)/ volar component (1mm thick),intermediate component (fibrocartilage) meniscus shape 2. Scapholunate dissociation is the most common form of wrist instability, defined as “the loss of synchronous motion or normal alignment between the scaphoid and the lunate”. 1 The mechanism of injury is typically a fall with the wrist extended and in ulnar deviation. Rupture of the scapholunate ligament is the first event in any sequence of perilunar ligament ruptures.

Scapholunate dissociation, also known as rotary subluxation of the scaphoid, refers to an abnormal orientation of the scaphoid relative to the lunate and implies

This is known as “scapholunate dissociation.” The bones also rotate abnormally after SL ligament tears, with the scaphoid rotating forward, and the lunate rotating backwards. This condition is known as “dorsal intercalated segmental instability” or “DISI” deformity.

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.
