Snapping hip syndrome, also known as dancer’s hip, is a condition characterized by a snapping sensation or an audible clicking sound in or around the hip joint during movement. This occurs when a muscle or tendon moves over a bony protrusion in the hip. While it is often painless, it can lead to irritation and inflammation of the surrounding tissues over time.

The primary symptom is the snapping noise or sensation, but other signs can develop if the condition progresses to bursitis or tendinitis.
Audible Snapping: A clear pop or click heard during activities like walking, getting up from a chair, or swinging the leg.
Internal Snapping: A sensation deep in the groin, often caused by the iliopsoas tendon catching on the pelvis.
External Snapping: A snap on the outside of the hip, usually caused by the iliotibial (IT) band sliding over the femur bone.
Swelling: Visible inflammation if the snapping causes a nearby bursa to become irritated.
Gradual Pain: While often painless at first, repetitive snapping can lead to a dull ache or sharp pain during specific movements.
Diagnosis focuses on identifying which specific tendon is causing the mechanical sound and whether there is associated joint damage.
Physical Assessment: A clinician will ask the patient to perform movements that trigger the snap, such as rotating the hip or moving from a flexed to an extended position.
Palpation: The doctor will feel the hip while it moves to pinpoint exactly where the tendon is catching.
X-rays: Used to rule out bone abnormalities or hip joint issues like loose bodies that could cause similar clicking sounds.
Ultrasound: This is highly effective because it allows the doctor to see the tendon snapping in real-time as the patient moves their leg.
MRI: Helpful if the doctor suspects the snapping is caused by a labral tear or internal joint damage rather than a muscle.
Conservative: Treatment is typically non-surgical and focuses on stretching the tight structures that are catching on the bone. Most patients find relief by modifying their activities to avoid repetitive snapping and by following a consistent stretching program. Strengthening the core and gluteal muscles also helps improve hip alignment, reducing the likelihood of the tendon catching on the bone.
Injection: If pain persists after physical therapy, a corticosteroid injection into the bursa can be done to reduce pain and swelling.
Surgery is rare for this condition. If surgery is pursued, the procedure would be to lengthen the tendon or remove a portion of the bone if conservative care fails.
