How is scapholunate interval measured?
- scapholunate interval should be measured at the midpoint of the adjacent parallel articular contours of the two bones (the scapholunate interval normally narrows proximal to distal)
- widening is exacerbated on. clenched fist views. PA views with wrist in ulnar deviation (causes intercalated segment extension)
What is SLIL ligament?
The scapholunate interosseous ligament (SLIL) is a U-shaped ligament which is arbitrarily divided into three anatomic components: dorsal, intermediate and volar 7: dorsal component: strongest, most important in resisting volar-dorsal translation.
What is degeneration of the scapholunate ligament?
Instability of the scapholunate articulation from traumatic tears or degenerative attenuation of the interosseous ligament is associated with progressive collapse and degeneration of the wrist. Degenerative arthritis in such cases follows a consistent radiographic pattern that begins at the radioscaphoid articulation.
What is the scapholunate joint?
The scapholunate joint is a small joint between two carpal bones at the wrist crease, namely the scaphoid and lunate bones. The scapholunate joint is very important for the stability of the wrist joint. It is often injured during sport, for example, if you fall heavily onto your hand.
What does widening of the scapholunate interval mean?
The scapholunate interval or gap is the radiographic measurement of the scapholunate joint and widening is indicative of a scapholunate ligament injury.
Can a scapholunate ligament tear heal on its own?
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. The goals of treatment are to decrease pain and prevent arthritis.
Will xray show torn ligament in wrist?
Although an x-ray will not show the ligaments themselves, it can suggest a ligament injury if the wrist bones do not line up correctly. An x-ray can also help your doctor rule out a broken bone in your wrist.
Can torn ligaments in wrist heal on their own?
Minor-to-moderate wrist ligament tears may heal on their own with home treatments like the RICE protocol. Rest: Rest the injured wrist typically for at least 48 hours. Ice: Use ice packs immediately after the injury to reduce pain and swelling; 20-30 minutes at a time, several times a day.
