Femoroacetabular Impingement: AI Imaging Assessment
Upload hip MRI or X-rays for AI assessment of cam and pincer morphology, alpha angle measurement, and associated damage.
Overview
Femoroacetabular impingement (FAI) occurs when abnormal bony morphology of the femoral head (cam type), acetabulum (pincer type), or both (mixed type) causes abnormal contact during hip motion. This leads to labral tears, cartilage damage, and eventually osteoarthritis. Imaging is essential for identifying FAI morphology, measuring alpha angles, assessing acetabular coverage, and evaluating associated soft tissue damage. Our AI consortium provides morphological assessment and measurements relevant to surgical planning.
Common Symptoms
- Groin pain worsening with hip flexion activities
- Pain with prolonged sitting or driving
- Reduced hip internal rotation range of motion
- Pain with sports involving pivoting, squatting, or kicking
- Stiffness in the hip, especially in the morning
- Pain that limits athletic performance
Key Imaging Findings
- Cam morphology with elevated alpha angle (greater than 55 degrees)
- Femoral head-neck junction bump or asphericity
- Pincer morphology with acetabular overcoverage (crossover sign)
- Coxa profunda or protrusio acetabuli
- Associated labral tear, most commonly anterosuperior
- Cartilage delamination at the chondrolabral junction
Frequently Asked Questions
What is the alpha angle and what is abnormal?
The alpha angle measures the sphericity of the femoral head-neck junction. It is measured on axial oblique MRI or lateral X-ray views. An alpha angle greater than 55 degrees is generally considered abnormal and indicative of cam morphology. Our AI measures the alpha angle when evaluating hip imaging.
