How is internal vs external snapping hip distinguished?

Internal snapping (coxa saltans interna): snapping felt anteromedially with hip flexion-extension, reproducible on ultrasound (iliopsoas tendon snapping). External snapping: lateral snapping over greater trochanter from IT band. Intra-articular snapping is often accompanied by mechanical symptoms (locking, giving way).

When is surgery indicated for internal snapping hip?

Surgery indicated for internal snapping after 6-12 months of conservative management (stretching, ultrasound-guided corticosteroid injection). Endoscopic iliopsoas tendon lengthening or fractional release gives 70-80% good-excellent outcomes.

What imaging is most useful for snapping hip?

Dynamic ultrasound is most diagnostic for external and internal snapping hip (visualizes the snapping in real time). MRI arthrogram evaluates intra-articular pathology (labral tear, cartilage injury, FAI morphology) as source of intra-articular snapping.

Snapping Hip (Coxa Saltans) Classification and Treatment

Classify snapping hip syndrome: external (IT band over greater trochanter), internal (iliopsoas over iliopectineal eminence), and intra-articular (labral tear, loose body). Internal and external types respond to stretching; intra-articular requires hip arthroscopy.
