Loss of integrity of the SLIL and persistent SL joint widening increase mechanical effects of the radial side wrist motor tendons, which may contribute to the pathomechanics of scaphoid malrotation, scapholunate advanced collapse, and early osteoarthritis in the radioscaphoid joint interface seen in SL dissociation.

Left untreated, scapholunate dissociation can lead to posttraumatic wrist arthritis. Multiple surgical procedures have been designed to reduce the scapholunate interval, restore normal wrist

A Scapho-Lunate Dissociation is a injury in your wrist. Two of your wrist bones, the Scaphoid and the Lunate, drift apart when an important ligament is torn (the SL Ligament). Our ligaments connect one bone to another. They keep our bones in alignment and they … Wrist kinetics after scapholunate dissociation: the effect of scapholunate interosseous ligament injury and persistent scapholunate gaps.

The scapholunate ligament is the most frequently injured ligament in the wrist, so is a common cause of wrist "sprains". A significant injury can alter the way the small bones of the wrist interact, and this can lead to cartilage wear and osteoarthritis.

It generates chronic instability, leading to osteoarthritis. It may be associated with fracture of the distal epiphysis of the radius or of the scaphoid.

It may be associated with fracture of the distal epiphysis of the radius or of the scaphoid. 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 (so called FOOSH ) in skiing or motorcycle Scapholunate Advanced Collapse (SLAC wrist) is due to advanced injury of the scapholunate and volar radioscapholunate ligaments which may lead to rotatory subluxation of the scaphoid and scapholunate dissociation. As in this severe case, the capitate may migrate proximally into the widened scapholunate space and articulate with the distal radius.

The goals of treatment are to decrease pain and prevent arthritis. Xray indicates scapholunate ligament instability when the scapholunate distance is more than 3 mm, which is called scapholunate dissociation.

Scapholunate Advanced Collapse (SLAC wrist) is due to advanced injury of the scapholunate and volar radioscapholunate ligaments which may lead to rotatory subluxation of the scaphoid and scapholunate dissociation. As in this severe case, the capitate may migrate proximally into the widened scapholunate space and articulate with the distal radius. INTRODUCTION: The Scapholunate dissociation is an injury to ligaments in the wrist that can lead to loosening of carpal bones. Scapholunate advanced collapse (SLAC) is a type of arthritis related to scapholunate dissociation .

Scapholunate dissociation represents a portion of a perilunar dislocation or The lesions of the scapholunate ligament are some of the most frequently encountered in the wrist. Left

SLD is one of the most common types of carpal instability. Scapholunate ligament tear diagnosis. A scapholunate ligament tear is usually caused by a fall or by a sudden load on the wrist. Sometimes the athlete may not recall the fall because they didn’t seek treatment immediately, but instead sought treatment weeks later when they continued to have pain. A scapholunate torn ligament does not heal on its own. If left untreated, a torn ligament typically leads to arthritis over time. This is because the bones of the wrist are no longer held in normal alignment.
