Understanding Greater Trochanteric Pain Syndrome (GTPS): Causes, Symptoms, and Treatment

What is Greater Trochanteric Pain Syndrome (GTPS)? Greater Trochanteric Pain Syndrome, often abbreviated as GTPS, is a common condition that causes pain in the outer hip and thigh area. It's not a single disease but rather a collection of issues that lead to discomfort around the top of the thigh bone, known as the femur. This syndrome is a frequent reason for people, especially women, to seek medical help for hip pain. While it can affect anyone, it's particularly prevalent in women between the ages of 40 and 60. Understanding GTPS is crucial for effective management and relief. Symptoms of GTPS The hallmark symptom of GTPS is pain located on the outer side of your hip and thigh. This pain can vary in intensity and may worsen under certain conditions: Prolonged sitting: Sitting for extended periods can aggravate the pain. Climbing stairs: The act of climbing stairs often increases discomfort. High-intensity activity: Strenuous physical activities can exacerbate the pain. Lying on the affected hip: Sleeping or resting on the side of the body with the painful hip can be very uncomfortable. Other symptoms might include a clicking or snapping sensation in the hip, and a general feeling of stiffness or reduced range of motion. Causes of GTPS GTPS is an umbrella term, and the pain can stem from several underlying issues: Trochanteric Bursitis: This is perhaps the most common cause. Bursae are small, fluid-filled sacs that cushion the bones, tendons, and muscles around your hip joint. When the bursa over the greater trochanter (a bony prominence on the outer side of the hip) becomes inflamed or irritated, it leads to pain. External Coxa Saltans (Snapping Hip Syndrome): This condition involves a snapping sensation as the hip moves, often caused by tendons sliding over the bony prominences of the hip. Iliotibial (IT) Band Syndrome: The IT band is a thick band of fibrous tissue that runs down the outside of the thigh, from the hip to the knee. Repetitive movements, especially in runners, can cause friction between the IT band and the greater trochanter, leading to inflammation and pain. Tendinopathy: Problems with the tendons that attach to the greater trochanter, such as inflammation or degeneration, can also cause GTPS. Several factors can contribute to the development of GTPS: Overuse or Repetitive Activity: Engaging in activities that involve repetitive hip motion, such as running, cycling, or prolonged walking, especially with increased intensity or volume, can irritate the structures around the greater trochanter. Biomechanical Factors: Leg length discrepancies (one leg being significantly shorter than the other) can alter gait and put uneven stress on the hips. Muscle Weakness or Imbalance: Weakness in the hip abductor muscles (muscles that move the leg away from the body) can lead to increased strain on the greater trochanteric region. Trauma or Injury: A direct blow to the hip or a fall can cause inflammation or injury to the bursa or surrounding tissues. Arthritis: While GTPS is distinct from hip osteoarthritis, underlying arthritis can sometimes contribute to or coexist with GTPS. Diagnosis of GTPS Diagnosing GTPS typically involves a combination of medical history, physical examination, and sometimes imaging tests: Medical History: Your doctor will ask about your symptoms, when they started, what makes them worse or better, and your activity levels. Physical Examination: The doctor will examine your hip, checking for tenderness over the greater trochanter. They might perform specific tests, such as asking you to stand on one leg and then the other. Pain within 30 seconds of standing on the affected leg is highly suggestive of GTPS. The ability to put on shoes and socks without significant pain can help differentiate GTPS from hip osteoarthritis, as people with GTPS usually don't have trouble with this motion. Imaging Tests: X-rays: These are often used to rule out other conditions like fractures or bony abnormalities in the pelvis or hip joint. Ultrasound or MRI: In some cases, these imaging techniques may be used to get a detailed view of the soft tissues, such as the bursa and tendons, to identify inflammation or tears. Treatment for GTPS Fortunately, GTPS is highly treatable, with about 90% of individuals experiencing relief through non-surgical methods. Treatment usually focuses on reducing inflammation, relieving pain, and strengthening the affected muscles. Conservative Treatments (First-Line) These are typically the initial approaches recommended: Activity Modification: Avoiding or reducing activities that aggravate the pain is crucial. This might mean temporarily stopping high-impact exercises or modifying your training routine. Pain Relief Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help reduce pain and inflammation. Always use these as directed by your doctor. Physical Therapy and Exercises: This is a cornerstone of GTPS treatment. A physiotherapist can guide you through specific exercises aimed at strengthening the hip abductor muscles, stretching tight muscles (like the IT band), and improving overall hip stability. Examples of exercises might include: Static Abduction: Lying on your side and lifting your top leg upwards, holding for a few seconds. Clamshells: Lying on your side with knees bent and lifting the top knee while keeping the feet together. Glute Bridges: Lying on your back with knees bent and lifting your hips off the floor. Weight Management: If you are overweight or obese, losing weight can significantly reduce the stress on your hip joint and surrounding structures. Ice and Heat Therapy: Applying ice packs to the affected area can help reduce inflammation, while heat can help

In summary, timely diagnosis, evidence-based treatment, and prevention-focused care improve long-term health outcomes.
