What is Snapping Hip Syndrome? 
Most of the time, this syndrome is not painful. However, it can cause pain and weakness that makes it hard to move or use the hip.
The snapping can also lead to a condition called bursitis. A bursa is a fluid-filled sac that cushions the bone from other moving parts, such as tendons, muscles, and skin. Bursae help your joints work smoothly. Bursitis is when a bursa becomes irritated or inflamed, and usually happens with injury or joint overuse. This snapping sensation happens when the tendon or muscle that is in the hip slides over one of the bony protrusions in your hip. This hip snapping can happen in different areas of the hip where muscles and tendons slide over knobby bumps in the hip bones.
Some places where hip snapping can occur is the:
- Outside of the hip, where the IT band passes over the greater trochanter [tro-CAN-ter] on the outside of your hip.
- Front of the hip, where the rectus femoris tendon moves across the head of the thighbone (femur).
- Back of the hip, where the hamstring starts at the ischial tuberosity (sit bone).
In some cases, hip snapping may be caused by a problem with loose the cartilage.
Symptoms
The symptoms of snapping hip syndrome may include:
- Snapping in the front, back, or side of the leg when moving the hip
- Tightness in the hip, usually the front or the back
- Swelling in the hip
- Weakness in the leg
- Having a hard time moving the hip, such as when standing from a sitting position
Causes
Diagnosis and Tests
To help diagnose your condition, your doctor will ask about your medical history, your injury, and your symptoms. 
Your doctor may also ask you to move your hip to try and get the hip to snap so they can see where the problem is. 
Your doctor may also request imaging tests, such as a CT scan or x-ray, to make sure there is nothing wrong with the inside of the hip. 
Treatments & Prevention
Treatments
