External Snapping Hip (ITB over Greater Trochanter) body chart — Illustrative, not diagnostic. Canva body chart for External Snapping Hip (ITB over Greater Trochanter).

Who: Dancers, runners, gymnasts. Anyone with high-volume repetitive hip flexion.
What: The iliotibial band or gluteus maximus snapping over the greater trochanter.
How it behaves: A lateral hip "snap," "click" or "clunk" with flexion–extension or rotation. May be painless or painful. Often worse with repetitive hip flexion — running, stairs, squats. Can coexist with GTPS or bursitis.

The one thing to take from this page:

The decision is binary. Painless snapping needs reassurance and nothing else. Painful snapping needs the lateral hip complex loaded and controlled — not the band released.

The binary

	What you do
Painless snap	Reassurance. Modify high-repetition snapping movements only if they bother them. That's it
Painful snap	Treat the lateral hip complex — glute med/max strength, single-leg control, trunk stability, technique. Clear GTPS and the joint

⚠️ Read this page's evidence base honestly. The literature is overwhelmingly surgical technique and outcome series. The conservative evidence is one feasibility study and one case report — and no study compares surgery with a loading programme.

2 · SE — THE SUBJECTIVE PATTERN (the 70%)

Five stages, in your course's order. One question decides the whole plan: does it hurt?

MAIN PROBLEM

"My hip clunks when I walk."
"It snaps every time I bring my leg through."
"It doesn't hurt, but it's driving me mad."

BODY CHART

Lateral, over the greater trochanter.
Mark whether there is pain at all, and where it sits relative to the snap.
Mark the deep anterior groin separately — an anterior snap is the iliopsoas, a different page.
Buttock or lateral thigh referral? Lumbar and SIJ.

BEHAVIOUR

	Fits external snapping hip	Points elsewhere
The snap	Lateral, over the greater trochanter, reproducible	Anterior, deep → internal snapping hip
Aggs	Repetitive hip flexion — running, stairs, squats, dance	Lying on that side, walking, stairs without a snap → GTPS
Severity	VAS 0–10 at best / at worst / right now	—
Pain	May be absent entirely	Deep anterior pinch with FADIR → hip joint
Mechanics	A reproducible snap	True locking, hip stuck → intra-articular
Age	Dancers, runners, gymnasts	Older with a fall and new lateral pain → fracture

HISTORY

Does it hurt, or is it only the noise? This is the question.
What is the actual concern? Pain, function, the sound in a dance class, or fear that something is damaged.
Training or dance volume and what changed.
Any lateral hip pain lying on that side? That is GTPS, and it coexists.
Any deep groin pain or pinching? That is the joint.

SPECIAL / SCREENING QUESTIONS

True locking — the hip stuck and needing to be freed? That is not a snap.
Any fall, and can they weight-bear?
Night pain, rest pain, weight loss, cancer history?
Progressive weakness?

3 · HYPOTHESIS RANKING

Competing pattern	The one discriminating feature
Gluteal tendinopathy (GTPS)	Lateral hip pain over the greater trochanter without the snap; worse lying on that side. Coexists commonly.
Internal snapping hip	The snap is anterior, from the iliopsoas. Different structure, different page.
Hip-related pain (FAI)	Deep anterior pinch, FADIR — and painful external snapping hip has been described alongside FAI [1].
Lumbar or SIJ referral	Lateral or buttock pain with lumbar behaviour and no reproducible snap.
Intra-articular clicking or loose body	True mechanical locking rather than a reproducible extra-articular snap.

The one that outranks the table

A fragility or stress fracture in the wrong patient. An older adult with new lateral hip pain after a fall, or an athlete who cannot weight-bear, is not a snapping hip problem regardless of what the hip does when they walk.

And the structural framing worth knowing

Current work argues the gluteal complex — not the iliotibial band alone — matters in external snapping hip [2], and an association with increased femoral offset has been reported [3]. Neither is established as causal, and both point the same way: treat the lateral hip complex, not the band.

4 · RED FLAGS — DON'T MISS THIS

This section is free, on every pattern, forever. Safety is never gated.

Finding	What it suggests	What you do
Older adult, new lateral hip pain after a fall	Fragility fracture	Image
Unable to weight-bear	Fracture	Urgent imaging. Do not load
True mechanical locking	Intra-articular loose body, labral tear	Orthopaedic review
Night pain or rest pain, unrelieved	Malignancy, infection	Medical review
Cancer history with new hip pain	Metastatic disease	Medical review
Lateral hip or thigh pain that won't behave — no better with treatment, or a dull night ache that only anti-inflammatories touch	Tumour mimicking GTPS — a gluteal metastasis treated as bursitis (Bertoli et al. 2003) [21], and an osteoid osteoma treated as GTPS for 9 months without an x-ray (Sferopoulos 2016) [22]	Image. Don't keep treating a lateral hip that isn't following the script
Fever, hot swollen hip	Septic arthritis, infected bursa	EMERGENCY
Progressive weakness or wasting	Neurological cause	Urgent medical review
RED-S profile in a dancer or runner	Bone stress injury	Image and refer

The rule: a reproducible lateral snap in someone who can weight-bear, with or without pain and with a clean systemic screen, is yours. A fall in an older adult, an inability to weight-bear, true locking or anything systemic is not.

Guideline anchor

No guideline of any nationality.

Anchored to the feasibility study of progressive resistance training (Kjeldsen et al. 2022, PMID 32643987) — which is essentially the entire conservative evidence base — and to the surgical systematic reviews (Pierce et al. 2018, PMID 29902932; Randelli et al. 2021, PMID 33064193) for what the rest of the literature contains.

PubMed Source

There is no guideline, no Australian document, and no study comparing conservative management with surgery. The literature is overwhelmingly surgical technique and outcome series; the conservative evidence is one feasibility study and one case report. Read every management statement on this page with that imbalance in mind.
