Snapping Hip

_Coxa Saltans_

Summary

A tendinous structure snapping over a bony prominence: external (ITB/TFL over greater trochanter), internal (iliopsoas over iliopectineal eminence/femoral head), or intra-articular (labral). Classify first, then treat.

Pathology. Snapping hip is a mechanical snap of a tendinous structure over a bony prominence — external (ITB/TFL over the greater trochanter) or internal (iliopsoas over the iliopectineal eminence/femoral head). It becomes symptomatic with tightness, overuse and poor pelvic control. Management reduces tension in the snapping structure and restores balanced hip strength; intra-articular causes require referral.

Clinical presentation (signs & symptoms)

Snapping/clicking with hip movement; lateral (external) or deep anterior-groin (internal) location; often in runners/dancers; may be painless, or painful with repetitive activity.

Assessment (Examination & Assessment)

Subjective

Audible/palpable snap or click with hip movement (rising from a chair, running, rotating). Locate type: external (lateral — ITB over greater trochanter), internal (anterior groin — iliopsoas over iliopectineal eminence/femoral head), intra-articular (labral). May be painless or painful. Pain scale.

Objective

Reproduce the snap: Ober's test / hip flexion–abduction–external rotation to extension for external (ITB); active hip flexion-to-extension for internal (iliopsoas); FADIR/FABER to screen intra-articular. Assess ITB & hip-flexor length, glute strength.

Differentiate from

Intra-articular pathology / labral tear (mechanical catching, positive FADIR) — refer if suspected.

Key special tests

| Test | What a positive result indicates | |---|---| | Ober's / hip circumduction (flexion-abduction-ER to extension) | reproduces the external (ITB) snap | | Active hip flexion-to-extension | reproduces the internal (iliopsoas) snap | | FADIR | screens for intra-articular/labral pathology | | FABER | hip / SIJ provocation and differentiation |

Red flags & when to refer

• Intra-articular/labral pathology (mechanical catching or locking, positive FADIR) — refer
• Hip instability or dysplasia
• Referred lumbar pain

Contraindications & precautions

• Iliopsoas dry needling is advanced (deep, near the femoral neurovascular bundle) — treat superficially or avoid unless specifically trained.
• General dry needling contraindications: infection, anticoagulants, needle phobia; consent & hygiene.
• Rule out intra-articular/labral pathology (true mechanical catching, positive FADIR) — refer if suspected.

Treatment protocol

Session structure & time scales

• Pre-assessment + prep (10 min): reproduce & classify snap; length/strength tests.
• Soft tissue — TFL/ITB & glutes (external) or iliopsoas/quads (internal) (12–15 min).
• Hip mobilisations (5 min).
• Dry needling — TFL/glute or (superficially) hip-flexor trigger points (8 min).
• Stretching demo — ITB / hip flexors (5 min).
• Glute/core loading demo (5–8 min).
• Reassessment + home programme (5 min).

Modalities & rationale

| Modality / technique | Rationale (why it is used for this pathology) | |---|---| | Soft tissue (TFL/ITB/glutes or iliopsoas) | reduces tension in the snapping structure, easing friction over the bony prominence. | | Hip mobilisations | improve joint glide and reduce compensatory tightness (Banks, 2013). | | Dry needling (TFL/glutes; hip flexors superficial) | relieves contributing trigger points (Sharkey, 2017). | | Stretching (ITB/hip flexors) | lengthens the snapping structure to reduce catching. | | Glute/core strengthening | corrects pelvic control and biomechanics — the longer-term driver. |

Loading & exercise progression

Glute-medius and core strengthening for pelvic control; progressive hip stability work; flexibility of the snapping structure (ITB or hip flexors).

Home care / self-management

ITB/hip-flexor stretching, glute-medius and core strengthening, running/technique and load-management advice, avoid repetitive provocative movements initially.

Outcome measures & re-assessment

• Pain scale (NPRS 0–10) pre/post; snap frequency/intensity.
• Repeat snap-provocation test.
• Reassess ITB/hip-flexor length (Ober's).
• Function during provocative movement.

Anatomy reference

| Structure | Origin | Insertion | Action | |---|---|---|---| | Tensor fasciae latae (TFL) | ASIS & anterior iliac crest | ITB → Gerdy's tubercle (lateral tibia) | hip flexion, abduction, internal rotation | | Iliopsoas (psoas major) | bodies & TPs T12–L5 | lesser trochanter of femur | hip flexion (trunk flexion) | | Iliacus | iliac fossa | lesser trochanter (with psoas) | hip flexion | | Gluteus maximus | posterior ilium, sacrum, coccyx | ITB & gluteal tuberosity | hip extension, external rotation |

Clinical reasoning (Q&A for the system)

_These question–answer pairs encode the expected clinical reasoning for this condition. Use them to justify decisions and to check generated plans._

Q: What are the three types of snapping hip and how do you tell them apart? A: External (ITB/TFL over the greater trochanter — lateral), internal (iliopsoas over the iliopectineal eminence/femoral head — anterior groin), and intra-articular (labral). Location and provocation test distinguish them.

Q: Which test reproduces each type? A: External: Ober's / hip circumduction from flexion-abduction-ER to extension. Internal: active hip flexion-to-extension. Intra-articular: FADIR to screen for labral pathology.

Q: Why is dry needling the iliopsoas considered advanced/risky? A: It is deep and lies near the femoral neurovascular bundle — treat superficially or avoid unless specifically trained.

Q: Give the origin, insertion and action of iliopsoas. A: Psoas major O: bodies/TPs T12–L5; iliacus O: iliac fossa; common I: lesser trochanter; A: hip flexion.

Q: What is your longer-term management beyond hands-on treatment? A: Glute-medius and core strengthening for pelvic control, ITB/hip-flexor flexibility and load/technique modification; refer if intra-articular/labral signs.
