Greater Trochanteric Bursitis: A Comprehensive Medical Guide

Overview

Greater trochanteric bursitis (GTB) is inflammation of the bursa that lies over the lateral‑side of the hip, specifically above the greater trochanter of the femur. The bursa is a small, fluid‑filled sac that normally reduces friction between the gluteus medius/minimus tendons and the bone. When the bursa becomes inflamed, patients experience pain and tenderness on the outer hip.

Who it affects

• Adults aged 40‑70 are most commonly diagnosed, with a slight female predominance (≈60 % of cases).<sup>1</sup>
• People who engage in repetitive hip‑abduction activities (runners, cyclists, hikers) are at higher risk.
• Individuals with obesity, osteoarthritis of the hip, or a history of lower‑extremity injury are also prone.

Prevalence

GTB accounts for roughly 10‑15 % of all hip pain presentations in primary‑care settings and up to 30 % of lateral hip pain complaints in orthopedic clinics.<sup>2</sup> Nationwide estimates suggest that between 1–2 % of adults will develop symptomatic GTB at some point in their lives.

Symptoms

Symptoms may develop gradually or appear after an acute over‑use event. Common features include:

• Lateral hip pain – aching or sharp pain that is most intense over the greater trochanter.
• Pain on pressure – tenderness when pressing on the outer hip or when lying on the affected side.
• Pain with hip abduction – discomfort when moving the leg outward (e.g., stepping sideways, crossing legs).
• Pain with prolonged walking or standing – may worsen after 10‑15 minutes of activity.
• Morning stiffness – a feeling of tightness after getting out of bed, usually improving after a few minutes of movement.
• Radiating pain – may travel down the outer thigh to the knee, mimicking sciatica.
• Swelling or palpable warmth – less common, but may be present in acute inflammation.
• Clicking or snapping – rarely, a “snapping” sensation occurs when the tendon slides over the inflamed bursa.

Symptoms are typically unilateral, but bilateral involvement occurs in up to 10 % of cases, especially in patients with systemic inflammatory diseases.

Causes and Risk Factors

Primary Causes

• Repetitive friction – frequent hip abduction (running, uphill walking) irritates the bursa.
• Tendon overload – tight gluteus medius/minimus tendons increase pressure on the bursa.
• Direct trauma – a fall onto the hip or a hard impact can cause acute bursitis.
• Degenerative hip arthritis – osteophytes can compress the bursa.
• Systemic inflammatory conditions – rheumatoid arthritis, polymyalgia rheumatica, and gout can involve the trochanteric bursa.

Risk Factors

• Age ≥ 40 years
• Female sex (higher prevalence of chronic tendinopathies)
• Obesity (BMI ≥ 30 kg/m²) – increased mechanical load on the hip
• Prolonged standing or occupational activities that require repetitive hip motion (e.g., carpenters, nurses)
• Previous hip surgery or fracture
• Low hip abductor strength (weak gluteus medius)
• Leg length discrepancy or abnormal gait patterns

Diagnosis

Diagnosis is primarily clinical, supported by imaging when needed.

History & Physical Examination

• Detailed description of pain location, onset, and aggravating factors.
• Inspection for swelling, erythema, or gait abnormalities.
• Palpation of the greater trochanter – tenderness is a hallmark sign.
• Specific maneuvers:
  • Trendelenburg test – assesses gluteus medius weakness.
  • Resisted hip abduction – reproduces pain when the bursa is compressed.

Imaging & Tests

• Plain radiographs – rule out osteoarthritis, fractures, or calcific deposits.
• Ultrasound – can visualize bursal fluid, thickening, and guide corticosteroid injection.
• MRI – gold standard for soft‑tissue evaluation; shows bursal enlargement, edema, and distinguishes bursitis from tendon tears.
• Laboratory studies (rarely needed) – ESR, CRP, or uric acid if systemic inflammation or gout is suspected.

Treatment Options

Management follows a stepwise approach: Conservative measures first, followed by interventional therapies if pain persists.

1. Medications

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – ibuprofen 400‑600 mg every 6‑8 h or naproxen 250‑500 mg twice daily for 2‑3 weeks (unless contraindicated).<sup>3</sup>
• Acetaminophen – for patients who cannot tolerate NSAIDs.
• Corticosteroid injection – 1 mL of 40 mg/mL methylprednisolone mixed with 1 mL of lidocaine under ultrasound guidance. Provides relief in 70‑80 % of cases within 48 hours.<sup>4</sup>
• Topical NSAIDs – diclofenac gel as an alternative for localized pain.

2. Physical Therapy & Exercise

• Gluteal strengthening – side‑lying clamshells, hip abduction with resistance bands, and single‑leg bridges.
• Stretching – iliotibial band, hip flexors, and piriformis stretches to reduce tension on the bursa.
• Aerobic conditioning – low‑impact activities (swimming, stationary bike) to maintain fitness without stressing the hip.
• Therapist‑guided gait retraining if leg‑length discrepancy or abnormal mechanics are identified.

3. Activity Modification

• Avoid prolonged standing, cross‑leg sitting, and deep squats for at least 2‑3 weeks.
• Use cushioned footwear and consider orthotics for leg‑length correction.

4. Advanced Interventions

• Image‑guided aspiration – removes excess fluid, provides diagnostic clarification.
• Platelet‑rich plasma (PRP) injections – emerging evidence suggests benefit in chronic refractory cases (Level II studies).<sup>5</sup>
• Surgical bursectomy – reserved for patients who fail ≥6 months of comprehensive non‑operative care. Open or endoscopic approaches have >90 % success rates.<sup>6</sup>

5. Adjunctive Therapies

• Ice application 15‑20 minutes, 3‑4 times daily during acute flares.
• Therapeutic ultrasound or low‑level laser therapy – modest pain reduction in some trials.

Living with Greater Trochanteric Bursitis

Adapting daily habits can significantly reduce discomfort and accelerate recovery.

• Positioning while sleeping – lie on the unaffected side with a pillow between the knees to keep the hips neutral.
• Work ergonomics – use a foot‑stool to alternate weight, take micro‑breaks every 30 minutes to stand and stretch.
• Footwear – choose supportive shoes with a modest heel; avoid high‑heeled or minimal‑sole shoes.
• Weight management – a 5–10 % reduction in body weight can lower joint load and improve pain scores.
• Hydration & nutrition – adequate protein and anti‑inflammatory foods (omega‑3 rich fish, berries) support tissue healing.
• Self‑monitoring – keep a pain diary to note triggers, medication response, and progress.

Prevention

Implementing preventive strategies can lower the likelihood of recurrence:

• Engage in regular, balanced lower‑extremity strengthening (2‑3 sessions per week).
• Incorporate dynamic stretching before activity and static stretching afterward.
• Gradually increase training volume; avoid “big jumps” in mileage or intensity.
• Maintain a healthy body weight (BMI < 25 kg/m² for most adults).
• Address biomechanical issues early—custom orthotics for overpronation or a leg‑length discrepancy.
• Use protective padding when participating in contact sports or activities with a risk of hip impact.

Complications

If left untreated or poorly managed, GTB can lead to:

• Chronic pain – persistent discomfort that interferes with sleep and daily function.
• Secondary tendinopathy – overload of the gluteus medius/minimus tendons can cause partial tears.
• Trochanteric bursal calcification – deposition of calcium crystals, often associated with gout or hyperparathyroidism.
• Functional gait abnormalities – a limp or Trendelenburg gait can develop, increasing fall risk.
• Compartment syndrome (rare) – massive fluid accumulation may raise pressure, requiring urgent decompression.
