Snapping hip is a click, clunk or snap you feel or hear as the hip moves. It’s common, and in most people it’s HARMLESS. If it doesn’t hurt, you don’t need to treat it.
There are three types:
- External: on the outside of the hip, where the IT band flicks over the bony point of the hip
- Internal: at the front of the hip, where a hip flexor tendon slides over bone
- Intra-articular: from inside the joint itself, usually a labral tear or a loose fragment
The first two are tendons moving over bone, and exercise usually settles any pain. The third is the one that needs a proper look.
How common it is
Somewhere around 1 in 10 to 1 in 20 people have a snapping hip.
It’s far more common in dancers, where as many as 9 in 10 report it, and it also turns up in runners, soccer players and weightlifters. It’s slightly more common in women and often happens in both hips. Most people with it have no pain at all.
Telling the types apart
- External snapping: you feel it on the outer hip, and you can often see or feel the band jump when you walk, climb stairs or swing the leg. Many people can make it happen on purpose
- Internal snapping: a deeper clunk at the front of the hip or groin, often when you straighten the hip from a bent position, like lowering a leg from a knee-to-chest position or rising from a chair
- Intra-articular: a catch or click deep in the groin with PAIN, sometimes a sharp twinge or a feeling that the hip locks for a moment
A snap that doesn’t hurt is just a noise. A catch that hurts is a question worth answering.
Exercises that help
If your snapping hip is painful, the aim is to calm the irritated tissue and make the hip muscles better at controlling the movement. Give it 6 to 12 weeks.
- Buttock strengthening: bridges, clamshells and side-lying leg lifts, building up to single-leg bridges and step-downs
- Hip flexor strength in a controlled range: seated knee lifts and standing marches with a light band, moving slowly through the range where the clunk happens
- Gentle stretches that feel good: a hip flexor stretch in a lunge position for internal snapping, and a stretch across the outer hip for external snapping. Stretch to mild tension, not pain
- Trunk control: exercises such as dead bugs and side planks help steady the pelvis
- Change what flares it: for a while, ease off the movement that snaps most, such as deep squats, high kicks or repeated leg swings
Stretching the IT band itself doesn’t lengthen it much, so strength work matters more than stretching. See IT band syndrome.
Pain on the outside of the hip
External snapping sometimes comes with pain over the bony point of the hip that is sore to lie on. That’s usually an irritated tendon or bursa rather than the snap itself. See gluteal tendinopathy and hip bursitis.
Other treatment
- Anti-inflammatory tablets for short spells, if your doctor says they suit you
- A steroid injection is sometimes used when the tendon or bursa stays painful despite exercise
- Surgery is rare. It’s used only when pain continues despite a proper trial of rehab, often through keyhole surgery to release or lengthen the tendon
The Cleveland Clinic has a clear overview of snapping hip syndrome.
When the snap needs attention
A painful catch deep in the groin, especially with the hip locking or giving way, points to the joint rather than a tendon. A common cause is a hip labral tear, and the approach is different.
Get seen urgently if
- You fell or twisted the hip and now can’t put weight on it
- The hip is hot, swollen and painful and you have a fever
- A child or teenager has a new limp, or hip, thigh or knee pain with no clear cause
Get it checked if
- The snapping has become painful and exercise hasn’t helped after 6 to 12 weeks
- The hip locks, catches with sharp pain, or gives way
- It started after an injury, such as a fall or a twist
- You’re limping or avoiding activities because of it
A painless snap needs no fixing. A painful one needs strength, and a locking one needs a diagnosis.
