What is the initial management for a patient with fluid in the right greater trochanteric bursa?

Initial Management of Fluid in the Right Greater Trochanteric Bursa

Begin with conservative management including NSAIDs, physical therapy with iliotibial band stretching and hip abductor strengthening, and activity modification, reserving corticosteroid injection for patients who fail initial measures. 1

Diagnostic Confirmation

Before initiating treatment, obtain plain radiographs to exclude other causes of hip pain such as fractures, osteoarthritis, or bony abnormalities. 1, 2

• Radiographs are the mandatory first imaging study to rule out alternative pathology including avulsion fractures at the greater trochanter, which can mimic trochanteric bursitis. 3, 2
• Ultrasound can confirm the presence of bursal fluid and evaluate the gluteal tendons, though distinguishing trochanteric bursitis from gluteus medius/minimus tendinosis may be difficult as these conditions frequently coexist. 1, 2
• MRI provides comprehensive assessment of peritrochanteric structures including the bursa, gluteus medius and minimus tendons, and can identify coexisting abductor tendon pathology. 1, 2

First-Line Conservative Treatment Algorithm

Step 1: Non-Invasive Measures (Initial 4-6 Weeks)

• NSAIDs for pain relief and anti-inflammatory effects should be the first pharmacologic intervention. 1
• Physical therapy focusing on iliotibial band stretching and eccentric strengthening of hip abductor muscles is essential and more effective than passive interventions. 1
• Activity modification to reduce repetitive loading and pressure on the affected bursa. 1
• Cryotherapy with ice application for 10-minute periods through a wet towel can provide acute pain relief. 1

Step 2: Corticosteroid Injection (If Conservative Measures Fail)

• Ultrasound-guided corticosteroid injection into the trochanteric bursa provides both diagnostic confirmation and therapeutic benefit when initial conservative measures fail after 4-6 weeks. 1, 2
• Ultrasound guidance significantly improves injection accuracy compared to landmark-based techniques. 1, 2
• This intervention is more effective than oral NSAIDs for acute phase pain relief, though it doesn't alter long-term outcomes. 1
• Symptom resolution with corticosteroid injection ranges from 49% to 100% when combined with multimodal conservative therapy. 4

Physical Therapy Specifications

Supervised exercise programs emphasizing eccentric strengthening of hip abductor muscles are superior to passive interventions such as massage, ultrasound, or heat therapy. 1

• Land-based physical therapy is preferred over aquatic therapy interventions. 1
• Passive modalities can supplement but should never substitute active physical therapy. 1
• Continue relative rest while allowing activities that don't worsen pain. 1

Advanced Treatment for Refractory Cases

If symptoms persist after 3-6 months of comprehensive conservative treatment including physical therapy, NSAIDs, and at least one corticosteroid injection:

• Extracorporeal shock wave therapy is a safe, noninvasive, and effective option for chronic cases, with level II and III evidence showing superiority over other nonoperative modalities. 1, 4
• Surgical intervention (bursectomy with or without iliotibial band release) should only be considered after failure of 3-6 months of comprehensive conservative treatment. 1, 4
• Surgical options include endoscopic or open bursectomy, longitudinal release or Z-plasty of the iliotibial band, and repair of gluteus medius tears if present. 4, 5

Critical Pitfalls to Avoid

• Do not confuse trochanteric bursitis with gluteus medius/minimus tendinosis, as these conditions frequently coexist and may require different treatment approaches. 1, 2
• In patients with hip prostheses, be cautious of misinterpreting adverse reactions to metal debris (ARMD) as trochanteric bursitis, as non-infected hip prostheses can show heterogeneous uptake in the greater trochanteric region. 3, 6, 2
• Avoid intratendinous corticosteroid injections, as injections directly into the tendon substance may have deleterious effects; peritendinous injections are preferred. 1
• Do not proceed to surgery without adequate conservative trial, as the majority of patients respond to nonoperative management and surgery should be reserved for truly refractory cases. 4, 7
