Scapholunate Injury: AI-Powered Imaging Analysis

AI-powered scapholunate ligament injury detection on wrist imaging. Assess widening, dorsal intercalated segment instability, and associated carpal malalignment. 4 AI models evaluate ligament integrity and carpal arcs.

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.
