Internal Snapping Hip Syndrome: Iliopsoas Impingement
The iliopsoas muscle is a blend of the psoas major and iliacus. These muscles lie in front of the hip joint and are the most powerful hip flexors (acting to pull the knee upward). (illustration here)
Signs and Symptoms
- an audible “snap” or click in or around the hip with certain movements
- most commonly seen in athletes performing repetitive hip flexion and extension
- -examples include: dance, soccer, gymnastics and running
What causes internal snapping hip syndrome?
- The tendon of the iliopsoas muscle sliding over the iliopectineal eminence
- (a bony ridge in front of the hip joint at the junction of the ilium and pubis) (illustration here)
- Other possibilities of places it can get caught?
