Clinical Presentation of Trochanteric Bursitis
Trochanteric bursitis typically presents with chronic, intermittent lateral hip pain and characteristic point tenderness over the greater trochanter, though current evidence suggests the pain often originates from gluteus medius or minimus tendinopathy rather than true bursal inflammation 1.
Primary Clinical Features
The hallmark presentation includes:
- Lateral hip pain that is chronic and intermittent in nature 2
- Exquisite point tenderness directly over the greater trochanter on palpation 1, 3
- Pain radiation to the posterolateral thigh 4
- Peak incidence between the fourth and sixth decades of life, with predominance in females and postmenopausal women 2, 5
Pain Aggravating Factors
Patients characteristically report worsening pain with specific activities 5:
- Lying on the affected side (most common complaint)
- Ascending or descending stairs
- Standing for short periods
- Crossing legs
- Direct pressure on the lateral hip
Associated Clinical Findings
The condition frequently coexists with or mimics other pathology 5, 4:
- Paraesthesias in the legs (can mimic nerve root compression)
- Tenderness along the iliotibial tract
- Low back pain - present in 18-45% of cases depending on patient setting 5
- May be associated with ipsilateral hip osteoarthritis or lumbar spondylosis 1
Important Clinical Pitfall
The diagnosis can be elusive when symptoms are atypical 2. The condition frequently mimics major hip pathology, low back pain, or nerve root compression syndrome 4. In fact, 83.4% of patients have pathologic conditions in adjacent areas (lumbar spine or hip joint) that can mask the actual source of pain 3.
Diagnostic Approach
After excluding lumbar spine or hip joint pathology clinically, the combination of lateral pain location plus characteristic trochanteric tenderness is usually sufficient for diagnosis 1. Laboratory tests and radiologic signs contribute minimally to diagnosis 3.
Local corticosteroid and anesthetic infiltration serves both as diagnostic test and treatment - rapid improvement after injection confirms the diagnosis 3. In one study, 90.3% of patients improved with local infiltration (73.8% after one injection, 20% after two injections) 3.
Contemporary Understanding
Recent evidence indicates that differentiation between true bursitis and gluteus medius tendinosis may be difficult, and the two conditions frequently coexist 6. Ultrasound studies show that 97.7% of clinically diagnosed GTPS patients have gluteus medius tendinopathy, with calcium deposits present in 97.7% of cases 7. Only 40.9% demonstrate actual bursa swelling on imaging 7.
