Definition and Overview
Greater trochanteric pain syndrome (GTPS), formerly known as trochanteric bursitis, is a clinical condition causing lateral hip pain due to inflammation or irritation of the trochanteric bursa and surrounding tendons.
1.1 What is Greater Trochanteric Pain Syndrome (GTPS)?
Greater Trochanteric Pain Syndrome (GTPS), previously referred to as trochanteric bursitis, is a condition characterized by pain and inflammation in the lateral hip region. It involves the trochanteric bursa, a fluid-filled sac located near the greater trochanter of the femur, and surrounding soft tissues such as tendons and muscles. GTPS encompasses various disorders, including bursitis, tendinopathy, and muscle imbalances, leading to discomfort and functional limitations. The condition is often associated with repetitive stress, muscle weakness, or biomechanical abnormalities. It primarily affects the outer hip area, causing pain that may radiate down the thigh or worsen with activities like sitting, climbing stairs, or lying on the affected side. GTPS is a clinical diagnosis, relying on patient history, physical examination, and imaging studies to confirm its presence and rule out other hip-related conditions.
1.2 Historical Perspective on Trochanteric Bursitis
Trochanteric bursitis, now more commonly referred to as Greater Trochanteric Pain Syndrome (GTPS), has been recognized as a source of lateral hip pain for decades. Historically, the condition was primarily attributed to inflammation of the trochanteric bursa, a fluid-filled sac located near the greater trochanter of the femur. However, advancements in understanding have broadened its definition to include a spectrum of pathologies involving the surrounding tendons, muscles, and soft tissues. Initially, treatment focused on addressing bursitis through surgical interventions or injections, but modern approaches emphasize a more comprehensive view, incorporating physical therapy, lifestyle modifications, and multidisciplinary care. The term GTPS was adopted to reflect this broader understanding, moving beyond isolated bursitis to encompass tendinopathies and other related conditions. This evolution highlights the complexity of hip pain syndromes and the need for tailored management strategies.
1.3 Anatomy of the Trochanteric Bursa
The trochanteric bursa is a fluid-filled sac located on the outer aspect of the hip, near the greater trochanter of the femur. It serves as a cushion, reducing friction between the femur and the overlying soft tissues, such as the iliotibial band and gluteal muscles. This bursa is bordered by the superior and inferior layers of the gluteus maximus muscle and lies close to the piriformis muscle, which can sometimes contribute to compression or irritation. The trochanteric bursa plays a crucial role in facilitating smooth movement of the hip joint, particularly during activities like walking or climbing stairs. Its strategic location allows it to absorb repetitive stress and prevent tissue damage, making it essential for maintaining normal hip function and mobility.
1.4 GTPS vs. Hip Bursitis: Key Differences
Greater trochanteric pain syndrome (GTPS) and hip bursitis are often confused due to overlapping symptoms, but they are distinct conditions. GTPS is a broader term encompassing pain in the lateral hip area, often caused by inflammation of the trochanteric bursa, tendinopathy, or muscle imbalances. In contrast, hip bursitis specifically refers to inflammation of the bursa, such as the trochanteric bursa. While hip bursitis is a localized condition, GTPS involves a combination of factors, including tendons and surrounding soft tissues. Symptoms of GTPS may radiate beyond the bursa, and treatment often addresses multiple contributing factors. Hip bursitis, however, is typically managed with targeted anti-inflammatory measures. Understanding these differences is crucial for accurate diagnosis and effective treatment, as GTPS may require a more comprehensive approach than isolated bursitis care.
Causes and Risk Factors
Repetitive motion, muscle imbalances, obesity, and age are primary causes, with biomechanical abnormalities and gender predominance as additional risk factors.
2.1 Repetitive Motion and Stress
Repetitive motion and stress are significant contributors to GTPS, often linked to activities like running, cycling, or jobs requiring prolonged standing. These movements strain the trochanteric bursa and surrounding tendons, leading to inflammation. Over time, repetitive hip movements can cause friction, irritating the bursa and surrounding soft tissues. This biomechanical stress is a common trigger, especially in individuals with pre-existing muscle imbalances or poor hip mechanics. Daily activities, such as climbing stairs or sitting for extended periods, can exacerbate the condition. Occupations involving repetitive hip flexion or external rotation are also at higher risk. Addressing repetitive stress through activity modification and strengthening exercises is crucial for prevention and management, as chronic irritation can lead to persistent pain and dysfunction if left unaddressed.
2.2 Muscle Imbalances and Weakness
Muscle imbalances and weakness, particularly in the hip abductors and external rotators, are key contributors to GTPS. Weakness in the gluteus medius and minimus muscles can lead to poor hip mechanics, altering gait and posture. This imbalance often results in excessive femoral internal rotation and adduction during activities like walking or running, which increases stress on the trochanteric bursa and surrounding tendons. Over time, this biomechanical inefficiency can cause inflammation and pain. Additionally, tight or overactive hip flexors and piriformis muscles can further exacerbate the condition by compressing the bursa. Addressing these muscle imbalances through targeted strengthening and stretching exercises is essential for both treatment and prevention of GTPS, as restoring proper hip function reduces repetitive strain on the affected area.
2.3 Biomechanical Abnormalities
Biomechanical abnormalities play a significant role in the development of GTPS. Structural issues such as femoral neck anteversion, coxa vara, or leg length discrepancies can alter normal hip mechanics, leading to increased stress on the trochanteric region. Abnormal gait patterns, such as an antalgic gait, may develop as a compensatory mechanism, further straining the bursa and surrounding tissues. Additionally, improper alignment of the hip joint can result in uneven distribution of forces during weight-bearing activities, exacerbating inflammation and pain. These biomechanical inefficiencies often require targeted interventions, such as orthotic devices or gait training, to restore proper movement patterns and reduce strain on the affected area. Addressing these abnormalities is crucial for effective management and prevention of GTPS.
2.4 Obesity and Body Weight
Obesity and increased body weight are significant risk factors for GTPS, as they place additional stress on the hip joint and surrounding tissues. Excess weight exacerbates mechanical stress on the trochanteric bursa during activities like walking, climbing stairs, or prolonged sitting. This heightened pressure can lead to inflammation and irritation of the bursa and adjacent tendons. Furthermore, obesity is associated with reduced mobility and altered gait patterns, which can further strain the hip region. Weight loss is often recommended as part of the management plan, as it can reduce the mechanical load on the affected area and alleviate symptoms. Maintaining a healthy weight is crucial for both prevention and recovery, as it addresses one of the key contributors to the development of GTPS.
2.5 Age as a Risk Factor
Age is a significant risk factor for GTPS, with the condition most commonly affecting individuals in middle age. As people grow older, biological changes such as tendon degeneration, reduced muscle flexibility, and decreased bursal resilience occur, making the hip region more susceptible to inflammation and irritation. Elderly individuals often experience a decline in physical activity levels, which can lead to muscle imbalances and altered biomechanics, further predisposing them to GTPS. Additionally, age-related conditions like osteoarthritis may exacerbate symptoms, as they place additional stress on the hip joint and surrounding tissues. Understanding the role of age in GTPS is crucial for developing targeted preventive and therapeutic strategies, especially in older populations where the condition is most prevalent.
2.6 Gender Predominance in GTPS
GTPS predominantly affects women, with studies indicating a significantly higher incidence in females compared to males. This gender disparity is attributed to several factors, including anatomical and hormonal differences. Women often have wider pelvises, which can lead to altered biomechanics and increased stress on the hip joint. Additionally, hormonal fluctuations during menopause may contribute to muscle weakness and tendon vulnerability. Women are also more likely to engage in activities that involve repetitive hip movements, such as certain sports or exercises, further increasing their risk. Understanding this gender predominance is essential for tailoring diagnostic and treatment approaches to address the unique needs of female patients, ensuring more effective management of GTPS symptoms and improving overall quality of life.
Symptoms of Trochanteric Bursitis
Trochanteric bursitis typically presents with lateral hip pain, tenderness over the trochanteric area, and pain exacerbated by activities like sitting, lying on the affected side, or climbing stairs.
3.1 Lateral Hip Pain: The Primary Symptom
Lateral hip pain is the hallmark symptom of trochanteric bursitis, typically presenting as discomfort or tenderness on the outer aspect of the hip. This pain often radiates to the nearby thigh and can worsen with activities such as prolonged sitting, lying on the affected side, or climbing stairs. The pain may be sharp or dull, depending on the severity of inflammation or irritation of the trochanteric bursa. In some cases, patients report aching or stiffness, particularly after periods of rest or inactivity. The lateral hip region may also be sensitive to direct pressure, such as when sleeping on the side or wearing tight clothing. This symptom is a key diagnostic feature, often prompting further evaluation to confirm the presence of trochanteric bursitis.
3.2 Tenderness Over the Trochanteric Area
Tenderness over the trochanteric area is a common symptom of trochanteric bursitis, often identified during physical examination. Patients typically experience discomfort when pressure is applied to the lateral aspect of the hip, particularly over the greater trochanter. This tenderness may be localized or radiate slightly, depending on the extent of inflammation. Clinicians often use palpation to assess the area, as pain upon touch can confirm the diagnosis. The tenderness is usually most pronounced when lying on the affected side or when direct pressure is applied to the trochanteric region. This symptom, combined with lateral hip pain, helps differentiate trochanteric bursitis from other hip-related conditions. Tenderness is a key diagnostic feature, often prompting further investigation into the underlying cause of the discomfort.

This exacerbation is a key factor in diagnosing and managing the condition, as it helps identify triggers and guide therapeutic interventions.
3.4 Limited Mobility and Stiffness
Limited mobility and stiffness are common symptoms of trochanteric bursitis, often affecting daily activities and overall quality of life. The inflammation and pain in the lateral hip region can restrict the range of motion, making it difficult to perform movements such as walking, climbing stairs, or even changing positions. Stiffness, particularly after periods of rest or in the morning, may further impair functional abilities. This reduction in mobility can lead to challenges in maintaining an active lifestyle and completing routine tasks, emphasizing the need for targeted interventions to restore flexibility and reduce stiffness. Addressing these issues is crucial for improving patient outcomes and enhancing mobility in individuals with trochanteric bursitis.
3.5 Associated Conditions and Symptoms
GTPS is often associated with other conditions, including tendinopathy, muscle imbalances, and referred pain from the lower back or sacroiliac joint. Patients may experience symptoms like piriformis syndrome, where the piriformis muscle irritates the sciatic nerve, leading to radiating pain. Additionally, soft tissue swelling and localized tenderness around the trochanteric area are common. Some individuals may also report difficulty sleeping due to persistent pain, further exacerbating discomfort. GTPS can coexist with osteoarthritis or labral tears, complicating the clinical picture. The condition often impacts quality of life, particularly in women, who report higher levels of pain and disability. Addressing these associated symptoms is essential for effective management and improving patient outcomes.
Diagnosis of GTPS
Diagnosis involves clinical evaluation, physical examination, imaging like X-rays or MRIs, and ruling out other conditions to confirm trochanteric bursitis or related issues.
4.1 Clinical Assessment and Patient History
Clinical assessment and patient history are crucial in diagnosing GTPS. Patients typically report lateral hip pain, worsened by activities like prolonged sitting or stair climbing. A thorough history reveals symptoms such as tenderness over the trochanteric area and pain during physical activities. Physicians assess for swelling, redness, or warmth around the hip. Patient history may include repetitive motion injuries or prior hip conditions. The incidence of GTPS is noted at 1.8 per 1000 patients annually, with women more frequently affected. Clinical evaluation involves palpation of the trochanteric bursa and assessment of hip mobility. Imaging studies like X-rays or MRIs may be recommended to rule out other conditions or confirm bursitis. The clinical approach ensures an accurate diagnosis, guiding appropriate treatment strategies for Trochanteric Bursitis.
4.2 Physical Examination Techniques
Physical examination techniques are essential for diagnosing GTPS. Physicians often begin with palpation of the lateral hip to identify tenderness over the trochanteric area. The FADIR (Flexion, Adduction, and Internal Rotation) test may be used to assess pain in the hip joint. Patients are also evaluated for pain during resisted abduction or external rotation, which can indicate tendinopathy. Gait analysis may reveal compensatory mechanisms or limited mobility. The examiner may check for swelling or redness around the trochanteric region. Pain upon direct pressure or movement suggests inflammation of the bursa or surrounding soft tissues. These physical findings, combined with patient history, help differentiate GTPS from other hip conditions, ensuring an accurate diagnosis and appropriate treatment plan.
4.3 Imaging Studies: X-rays, MRIs, and Ultrasound
Imaging studies are crucial for confirming the diagnosis of GTPS and ruling out other hip pathologies. X-rays are often the first imaging modality used to assess bony structures, though they may appear normal in early stages of GTPS. Magnetic Resonance Imaging (MRI) provides detailed visualization of soft tissues, including the trochanteric bursa, tendons, and muscles. MRI can detect bursal inflammation, tendon tears, or muscle atrophy. Ultrasound is another valuable tool, offering real-time imaging to identify fluid collection in the bursa or tendon abnormalities. It is particularly useful for guiding injections or aspirations. While clinical assessment is primary, imaging helps confirm the extent of tissue involvement and guides treatment decisions, ensuring a comprehensive approach to managing GTPS.
4.4 Differential Diagnosis Considerations
Differential diagnosis for GTPS involves ruling out other conditions that present with similar symptoms, such as hip osteoarthritis, sciatica, or piriformis syndrome. Hip osteoarthritis typically involves pain in the groin and limited joint mobility, whereas GTPS primarily affects the lateral hip. Sciatica, caused by nerve compression, may radiate pain down the thigh but lacks localized tenderness over the trochanter. Piriformis syndrome, involving the piriformis muscle, can mimic GTPS but often includes pain with sitting or specific hip movements. Additionally, tendinopathies of the gluteal tendons and referred pain from lumbar spine disorders should be considered. A thorough clinical assessment and imaging studies help distinguish GTPS from these conditions, ensuring accurate diagnosis and appropriate treatment.
Treatment Options
Trochanteric bursitis treatment includes NSAIDs, corticosteroid injections, and physical therapy. Lifestyle modifications and surgery are considered in severe cases. These approaches aim to reduce pain and restore mobility effectively.
5.1 Medical Management: NSAIDs and Corticosteroids
Medical management of trochanteric bursitis often involves the use of nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. Examples include ibuprofen and naproxen, which can be taken orally or applied topically. For severe cases, corticosteroid injections into the affected bursa may be recommended to decrease swelling and alleviate symptoms. These injections are typically administered under ultrasound guidance to ensure accuracy. While NSAIDs are effective for short-term relief, corticosteroids provide longer-lasting benefits. However, both treatments should be used cautiously, as prolonged use can lead to side effects. Medical professionals often combine these treatments with physical therapy and lifestyle modifications for optimal outcomes. Patient response to these therapies can vary, but they remain cornerstone treatments for managing symptoms effectively.
5.2 Physical Therapy Interventions
Physical therapy plays a crucial role in managing trochanteric bursitis by addressing muscle imbalances and improving joint mobility. A tailored exercise program often includes stretching exercises for the hip flexors, piriformis, and IT band to reduce tension around the trochanteric area. Strengthening exercises targeting the gluteal muscles, particularly the gluteus medius and minimus, are essential to enhance hip stability and reduce pain. Manual therapy techniques, such as soft tissue mobilization and joint mobilizations, may also be incorporated to alleviate stiffness and promote healing. Additionally, physical therapists may recommend activity modifications, such as avoiding prolonged sitting or high-impact activities, to prevent exacerbation.
