Clicking Left Hip Pain When Turning in Bed
The clicking sensation with hip pain when turning in bed is most likely caused by snapping hip syndrome (coxa saltans) or intra-articular pathology such as a labral tear, and should be managed initially with physiotherapist-led exercise therapy focusing on hip muscle strengthening and movement control.
Differential Diagnosis
The clicking hip pain has several potential causes that must be distinguished:
Snapping Hip Syndrome (Coxa Saltans)
This is characterized by an audible or palpable snap with hip movement 1, 2. The syndrome has two main types:
- Internal snapping: Caused by iliopsoas tendon subluxation over bony prominences (anterior inferior iliac spine, iliopectineal eminence) 1
- External snapping: Related to iliotibial band or gluteus maximus moving over the greater trochanter 2
Intra-articular Pathology
Clicking can indicate:
- Labral tears: Often present with painful clicking or popping, particularly in younger active adults 2
- Femoroacetabular impingement (FAI) syndrome: May cause clicking with aberrant joint forces during hip movements 3
- Chondral injuries: Can manifest as intra-articular snapping 2
Lateral Hip Pain Syndromes
Greater trochanteric pain syndrome (GTPS) can present with lateral hip pain, though clicking is less characteristic 4, 5.
Diagnostic Approach
Imaging should never be used in isolation but must be combined with symptoms and clinical signs 6.
Initial Imaging
Obtain anteroposterior pelvis and lateral femoral head-neck radiographs (Dunn view, frog-leg view, or cross-table view) to assess hip morphology 6. This provides understanding of underlying bony architecture relevant to the pain presentation.
Advanced Imaging Considerations
MRI/MRA or CT arthrogram is indicated when:
- Intra-articular structures (labrum, cartilage, ligamentum teres) need assessment 6
- Three-dimensional morphological evaluation is required 6
Critical caveat: Incidental intra-articular findings are common in asymptomatic individuals, so imaging findings must correlate with clinical presentation 6. Diagnostic imaging has only small to moderate shifts in post-test probability, even with positive findings 6.
Clinical Examination Priorities
- Location of pain (anterior groin suggests intra-articular; lateral suggests GTPS; clicking location helps differentiate internal vs external snapping)
- Reproducibility of the click with specific movements
- Screen for lumbar spine and pelvic pathology as potential pain sources 6
Important limitation: Most clinical special tests have very limited ability to confirm specific hip diagnoses, and their use is not recommended for ruling conditions in or out 6.
Management Algorithm
First-Line Treatment: Physiotherapist-Led Rehabilitation
Physiotherapist-led exercise therapy is the primary treatment for hip-related pain in young to middle-aged active adults 3. This approach has demonstrated long-term benefits for most patients 4.
The exercise program should include:
- Hip muscle strengthening: Target hip flexors, abductors, and core stabilizers
- Movement control training: Address aberrant movement patterns
- Activity modification: Reduce aggravating movements during rehabilitation phase
Exercise parameters to implement:
- Load magnitude, repetitions, and sets should be progressively increased
- Duration and frequency tailored to individual tolerance
- Time under tension and rest periods optimized for strengthening 3
Adjunctive Treatments for Acute Symptoms
Combining physiotherapy with corticosteroid injections is more effective for acute symptoms than PT alone 4. However:
- CSI provides short-term relief only
- Long-term outcomes favor PT alone (60.5% symptom resolution at 15 months) 4
- CSI should be used strategically to facilitate participation in PT, not as standalone treatment
Alternative Conservative Options
Extracorporeal shock wave therapy (ESWT) showed 68.3% improvement in pain scores compared to controls 4, though evidence is limited. Consider when PT progress plateaus.
Platelet-rich plasma (PRP) has inconclusive evidence and cannot be recommended as standard treatment 4.
Surgical Intervention
Surgery is reserved for failed conservative management 4. Specific indications:
- Internal snapping hip: Partial iliopsoas tendon release and lengthening, with minimal lesser trochanteric bony ridge resection if involved 1
- Labral tears or FAI syndrome: Arthroscopic correction of morphology and labral/chondral damage 2
- GTPS with tendon tears: Surgical repair when conservative measures fail 4
Common Pitfalls to Avoid
Do not diagnose based on imaging alone: The combination of symptoms, clinical signs, and imaging is essential 6
Do not over-interpret incidental findings: Asymptomatic labral tears and other abnormalities are common on MRI 6
Do not expect immediate results from PT: Improvements may take months, with optimal outcomes at 15 months 4
Do not use CSI as monotherapy: Always combine with structured PT program for sustained benefit 4
Do not skip comprehensive screening: Lumbar spine and pelvic pathology can refer pain to the hip 6, 7
Treatment Timeline
Start with 3-6 months of structured physiotherapist-led exercise therapy 3. If acute pain limits participation, consider CSI to facilitate PT engagement 4. Reassess at 3-4 months; if no improvement, consider advanced imaging (if not already obtained) and specialist referral for surgical evaluation 2.
