Bursitis of the Hip (Trochanteric Bursitis) – A Comprehensive Guide

Overview

Trochanteric bursitis is inflammation of the bursa located over the greater trochanter of the femur, the bony prominence on the outer side of the hip. The bursa is a small, fluid‑filled sac that reduces friction between the gluteus medius/minimus tendons and the outer hip bone during movement. When it becomes inflamed, pain and tenderness develop at the side of the hip.

Although the term “bursitis” implies infection, most cases are non‑infectious and result from overuse, repetitive friction, or systemic conditions. The condition is also called “greater trochanteric pain syndrome” when other structures (e.g., tendons) contribute to the pain.

Who it affects:

• Adults aged 40–70 years are the most common group.
• Women are slightly more often affected than men (≈55% vs. 45%).
• People with occupations or hobbies that involve prolonged standing, climbing stairs, or repetitive hip motion (e.g., carpenters, runners) have higher rates.

Prevalence: Epidemiologic studies estimate that trochanteric bursitis accounts for 15–30% of all hip pain complaints in primary‑care clinics and up to 5% of all visits for musculoskeletal pain in the United States each year (CDC, 2022).

Symptoms

Symptoms can range from mild irritation to severe, debilitating pain. They often worsen with activities that stress the outer hip.

• Local pain on the outside of the hip – a deep, achy sensation that may feel sharp when pressure is applied.
• Tenderness to touch – pressing on the greater trochanter reproduces the pain (positive “night‑glide” test).
• Pain while walking or climbing stairs – especially when the leg is lifted to the side (abduction) or when the foot is planted.
• Pain when lying on the affected side – can disrupt sleep.
• Swelling or a palpable lump – in chronic cases the bursa may become mildly enlarged.
• Stiffness or reduced range of motion – typically mild, but may limit activities such as squatting.
• Radiating pain – sometimes pain can travel down the lateral thigh, mimicking sciatica.
• Warmth or redness – uncommon, but if present it may suggest an infectious (septic) bursitis.

Causes and Risk Factors

Primary (non‑infectious) causes

• Repetitive friction between the gluteal tendons and the trochanter—common in runners, cyclists, and people who frequently climb stairs.
• Trauma – a direct blow to the hip or a fall can irritate the bursa.
• Hip osteoarthritis – joint degeneration alters biomechanics, increasing stress on the bursa.
• Greater trochanteric pain syndrome – tendinopathy of the gluteus medius/minimus often coexists with bursitis.
• Systemic inflammatory diseases – rheumatoid arthritis, gout, and ankylosing spondylitis can involve bursae.

Infectious (septic) bursitis

• Usually follows a skin abrasion, injection, or hematogenous spread of bacteria (most often Staphylococcus aureus).
• More common in immunocompromised patients, diabetics, or those with chronic skin conditions.

Risk Factors

• Age > 40 years
• Female sex
• Obesity (BMI ≥ 30) – increased mechanical load on the hip
• Occupational or recreational activities requiring prolonged hip abduction
• Previous hip injury or surgery
• Systemic inflammatory disorders (RA, gout, etc.)
• Diabetes mellitus – higher risk of septic bursitis

Diagnosis

Diagnosis is primarily clinical, supported by imaging or laboratory tests when the presentation is atypical.

Clinical examination

• Inspection – may reveal swelling or a visible limp.
• Palpation – tenderness over the greater trochanter is the hallmark sign.
• Gait assessment – a Trendelenburg gait (hip drop on the opposite side) can indicate gluteal muscle weakness.
• Special tests – the “Hip Resisted Abduction” test reproduces pain in >80% of patients with trochanteric bursitis.

Imaging

• Plain X‑ray – rules out fractures, osteoarthritis, or bone lesions; usually normal in isolated bursitis.
• Ultrasound – can visualize bursal fluid, thickening, and hyperemia; useful for guiding needle aspiration.
• MRI – gold standard for soft‑tissue evaluation; shows bursal edema, fluid distention, and any concurrent tendon pathology.

Laboratory tests

• Inflammatory markers (ESR, CRP) – may be mildly elevated in non‑infectious bursitis; markedly high levels raise suspicion for infection.
• Aspiration of bursal fluid – indicated when infection is suspected; fluid analysis includes gram stain, culture, and cell count.

Treatment Options

Most cases improve with conservative measures within 6–12 weeks. Treatment is staged from least to most invasive.

1. Medications

• NSAIDs (e.g., ibuprofen 400–600 mg q6‑8 h) – reduce inflammation and pain. Use the lowest effective dose; monitor for gastrointestinal or renal side effects (Mayo Clinic, 2023).
• Acetaminophen – an alternative for patients who cannot tolerate NSAIDs.
• Corticosteroid injection – a single intra‑bursal injection of methylprednisolone (40–80 mg) with lidocaine provides rapid relief in 70–80% of patients. Repeated injections should be limited to ≤3 per year to avoid tendon weakening.
• Antibiotics – reserved for confirmed septic bursitis (e.g., oral dicloxacillin or IV cefazolin for MSSA).

2. Physical Therapy & Rehabilitation

• Stretching – iliotibial band (ITB) and hip flexor stretches performed 3–5 times daily.
• Strengthening – progressive resistance exercises for gluteus medius/minimus (side‑lying leg lifts, clamshells, banded abductions) 2–3 times per week.
• Modalities – ice packs for 15 min after activity, ultrasound or low‑level laser therapy may reduce pain.
• Gait training – use of a walking stick or cane temporarily to off‑load the affected side.

3. Activity Modification

• Temporarily avoid prolonged standing, stair climbing, or high‑impact activities.
• Switch to low‑impact cardio (e.g., swimming, stationary cycling) while symptoms persist.

4. Procedural Interventions

• Ultrasound‑guided bursal aspiration – both diagnostic (fluid analysis) and therapeutic (decompression).
• Platelet‑rich plasma (PRP) injections – emerging evidence suggests benefit for chronic recalcitrant cases, but data are still limited.
• Surgical bursectomy – indicated only after ≥6 months of failed conservative therapy, persistent severe pain, or confirmed septic bursitis requiring debridement. Performed arthroscopically with an average recovery time of 8–10 weeks.

5. Lifestyle & Home Care

• Weight loss if BMI > 30 – each 5‑kg reduction can lower hip joint load by ~10%.
• Ergonomic adjustments at work (e.g., anti‑fatigue mats, frequent micro‑breaks).
• Footwear with good cushioning and arch support.

Living with Bursitis of the Hip (Trochanteric Bursitis)

Daily Management Tips

• Ice first – apply a cold pack for 15 minutes after activity to limit inflammation.
• Gentle stretching routine – 5‑minute ITB and hip flexor stretch every morning and evening.
• Strengthen before you strain – incorporate glute‑medius strengthening 3 times per week; stronger muscles protect the bursa.
• Use supportive cushions – when sitting for long periods, a donut‑shaped pillow reduces pressure on the greater trochanter.
• Schedule rest breaks – stand up, walk, and gently move the hip every 30‑45 minutes if you have a desk job.
• Monitor pain levels – keep a simple pain diary (0‑10 scale) to track triggers and treatment response.
• Medication adherence – take NSAIDs with food, and discuss any stomach issues with your clinician.

When to Return to Full Activity

Most patients can resume normal activities when pain is ≤2/10 at rest, there is no pain during resisted hip abduction, and they can walk briskly for at least 30 minutes without aggravation. A gradual progression—adding 10% more activity each week—is recommended to avoid relapse.

Prevention

• Maintain a healthy weight – body‑mass index < 25 reduces mechanical stress on the hip.
• Regular hip‑strengthening program – at least two sessions per week focusing on gluteus medius/minimus and core stability.
• Stretch the IT band and hip flexors – daily flexibility work prevents tightness that rubs the bursa.
• Use proper footwear – cushioned shoes with arch support diminish impact forces.
• Modify high‑risk activities – alternate running with swimming or cycling; use a padded bike saddle.
• Ergonomic workstation – ensure the chair height allows hips to be slightly higher than knees and use anti‑fatigue mats if standing.
• Prompt treatment of skin wounds around the hip area – reduces the chance of bacterial entry leading to septic bursitis.

Complications

If left untreated, trochanteric bursitis can lead to:

• Chronic pain – may become refractory and impact quality of life.
• Secondary gluteal tendinopathy – persistent inflammation can weaken tendons, leading to tears.
• Gait abnormalities – a limp can cause compensatory stress on the lumbar spine and opposite hip, increasing risk of low‑back pain.
• Septic bursitis – though rare (≈2–5% of cases), infection can spread to surrounding tissue and, if undetected, cause systemic sepsis.
• Hip osteoarthritis progression – chronic inflammation may accelerate cartilage wear.
