What is the appropriate evaluation and first‑line management for a patient with lateral hip pain due to greater trochanter syndrome (trochanteric bursitis or gluteus medius/minimus tendinopathy)?

Greater Trochanter Syndrome: Evaluation and Management

Begin with plain radiographs of the pelvis and hip to exclude alternative pathology, followed by ultrasound or MRI without contrast if imaging is needed to confirm the diagnosis of gluteal tendinopathy or trochanteric bursitis, then initiate conservative management with structured physical therapy for at least 3 months combined with NSAIDs or acetaminophen. 1

Initial Diagnostic Approach

Clinical Evaluation

Look for these specific features:

• Lateral hip pain with point tenderness over the greater trochanter
• Pain exacerbated by activity, relieved with rest
• Pain with resisted hip abduction or external rotation
• Positive FADIR test (flexion-adduction-internal rotation) 2
• Middle-aged women are most commonly affected 3, 4

Critical pitfall: Do not diagnose based on clinical examination alone—GTPS shares overlapping features with lumbar radicular pain, hip osteoarthritis, and intra-articular hip pathology 5.

Imaging Algorithm

Step 1: Plain Radiographs

• Radiographs of the pelvis and hip should be the first test ordered to exclude hip osteoarthritis, fractures, or other bony pathology 1

Step 2: Soft Tissue Imaging (if radiographs negative/equivocal)

• Ultrasound is the preferred first-line soft tissue imaging due to availability, low cost, dynamic assessment capability, and ability to guide injections 1, 5
• MRI without IV contrast is appropriate when ultrasound is unavailable or when there is diagnostic uncertainty requiring comprehensive soft tissue evaluation 1

What to look for on imaging:

• Gluteus medius and minimus tendinopathy or tears (present in 97.7% of GTPS cases) 6
• Calcium deposits within tendons (present in 97.7% of cases) 6
• Trochanteric bursa distension (present in 40.9% of cases) 6
• Muscle atrophy and loss of fibrillar pattern correlate with dysfunction 6

First-Line Management

Conservative Treatment Protocol

1. Structured Physical Therapy (Primary Treatment)

• Duration: Minimum 3 months 7
• Exercise-based treatment is the cornerstone of management 7
• Focus on hip abductor strengthening and biomechanical correction
• Physical activity and sport participation should be encouraged, not restricted 7

2. Pharmacological Management

• NSAIDs at the lowest effective dose when not contraindicated 8
• Acetaminophen (up to 4g/day) may be considered as an alternative 8
• Avoid opioids for this condition 8

3. Adjunctive Interventions

• Corticosteroid injections (ultrasound-guided preferred) provide short-term relief but diminishing long-term benefit 3, 9

  • Use when symptoms are refractory to initial conservative measures 8
  • Ultrasound guidance is superior to landmark-based injection 3

• Extracorporeal shock wave therapy (ESWT) provides significant long-term pain relief 3

• Platelet-rich plasma (PRP) injections demonstrate sustained improvement and may be considered for refractory cases 3

Treatment Selection Based on Imaging Findings

If bursa distension is present: Patients may have less pain and respond well to corticosteroid injection 6

If severe tendinopathy with calcium deposits and partial tears: Consider ESWT or PRP rather than corticosteroids alone 3, 6

If muscle atrophy present: Emphasize structured physical therapy as dysfunction correlates with atrophy 6

When Conservative Management Fails

Surgical intervention should be considered only after:

• Minimum 3-6 months of failed conservative therapy 4, 10
• Documented compliance with structured physical therapy
• Failed trial of image-guided corticosteroid injection

Approximately one-third of patients fail initial conservative therapy and may require advanced interventional strategies 9.

Common Pitfalls to Avoid

1. Do not diagnose "trochanteric bursitis" based on clinical exam alone—the primary pathology is gluteal tendinopathy in the vast majority of cases 3, 4, 6

2. Do not skip radiographs—they are essential to exclude hip joint pathology that would require different management 1

3. Do not use ultrasound or MRI in isolation—imaging must be combined with clinical findings as asymptomatic tendinopathy is common 2, 4

4. Do not provide short-duration physical therapy—minimum 3 months is required for adequate trial 7

5. Do not perform blind corticosteroid injections—ultrasound guidance significantly improves accuracy and outcomes 3
