Scapholunate Injury: AI-Powered MRI Assessment
Upload your wrist MRI or X-rays for AI analysis of scapholunate ligament tears, widening, and carpal instability assessment.
Overview
The scapholunate (SL) ligament is the most important intrinsic carpal ligament and its disruption leads to progressive carpal instability known as scapholunate advanced collapse (SLAC). SL injuries range from partial tears to complete rupture with dissociation. Imaging evaluates ligament integrity, scapholunate interval widening, carpal alignment, and secondary degenerative changes. Our AI consortium assesses SL ligament morphology, measures the scapholunate gap, evaluates scapholunate angle, and identifies signs of carpal malalignment.
Common Symptoms
- Dorsal wrist pain over the scapholunate interval
- Pain worsening with wrist extension and gripping
- Reduced grip strength
- Wrist swelling after activity
- Clicking or clunking during wrist motion
- Progressive wrist stiffness over time
Key Imaging Findings
- Scapholunate ligament tear or discontinuity on coronal MRI
- Scapholunate interval widening greater than 3mm on X-ray (Terry Thomas sign)
- Increased scapholunate angle greater than 60 degrees
- Cortical ring sign on PA view indicating rotary subluxation of scaphoid
- Dorsal intercalated segment instability (DISI) pattern
- SLAC wrist degenerative changes in chronic injuries
Frequently Asked Questions
What is SLAC wrist?
SLAC (Scapholunate Advanced Collapse) wrist is the predictable pattern of degenerative arthritis that develops after chronic scapholunate ligament injury. It progresses from radial styloid-scaphoid arthritis to midcarpal arthritis. Our AI evaluates for SLAC progression patterns when analyzing chronic wrist injuries.
