Ultrasound-Guided Cortisone Injections for Greater Trochanteric Pain Syndrome (GTPS)

 Greater Trochanteric Pain Syndrome (GTPS) is a common cause of lateral hip pain that can significantly impact daily activities and quality of life. This condition involves inflammation or degeneration of the structures around the greater trochanter, a prominent bony part of the femur. Among the various treatment options, ultrasound-guided cortisone injections have emerged as a precise and effective approach for managing GTPS symptoms.

At Alton Pain Clinic, we specialise in offering advanced, minimally invasive treatments like ultrasound-guided cortisone injections. This blog provides an in-depth understanding of GTPS and explores how cortisone injections can provide targeted relief for this condition.

Greater Trochanteric Pain Syndrome

Understanding Greater Trochanteric Pain Syndrome

GTPS refers to a spectrum of conditions affecting the lateral aspect of the hip, including:

  • Trochanteric bursitis (inflammation of the bursa).
  • Gluteal tendinopathy (degeneration or injury of the gluteal tendons).
  • External snapping hip syndrome (associated with iliotibial band irritation).

While GTPS was historically referred to as trochanteric bursitis, recent studies reveal that most cases involve gluteal tendinopathy rather than isolated bursal inflammation.

Anatomy of the Greater Trochanter

The greater trochanter is a large, bony prominence on the lateral side of the femur. It serves as an attachment site for key hip stabilising muscles, including:

  • Gluteus medius and gluteus minimus tendons.
  • Iliotibial (IT) band, which runs along the lateral thigh.
  • Trochanteric bursae, small fluid-filled sacs that reduce friction between tendons and the bone.

These structures work in harmony to stabilise the hip joint during movement, particularly in activities like walking, running, and climbing stairs.

Pathology of GTPS

GTPS develops when the tendons or bursae around the greater trochanter become irritated or inflamed. Contributing factors include:

  • Tendinopathy: Chronic overuse or degeneration of the gluteal tendons.
  • Bursal Inflammation: Repetitive friction or trauma can inflame the trochanteric bursae.
  • IT Band Irritation: Tightness or excessive tension in the IT band can lead to friction over the greater trochanter.

Risk factors for GTPS include:

  1. Repetitive Movements: Activities like running, cycling, or stair climbing.
  2. Hip Joint Instability: Weakness in surrounding muscles.
  3. Postural Issues: Abnormal gait or pelvic tilt.
  4. Trauma: Direct injury to the hip region.
  5. Obesity: Increased stress on the hip stabilisers.

Symptoms of GTPS

The hallmark symptoms of GTPS include:

  1. Lateral Hip Pain: Localised around the greater trochanter, often worsening with pressure (e.g., lying on the affected side).
  2. Radiating Pain: May extend to the lateral thigh but rarely beyond the knee.
  3. Tenderness: Over the greater trochanter on palpation.
  4. Reduced Mobility: Difficulty with activities such as climbing stairs or standing for long periods.
  5. Pain with Physical Activities: Exacerbated by walking, running, or crossing legs.

Diagnosis of GTPS

Diagnosing GTPS involves a thorough clinical evaluation and imaging studies to rule out other hip or lumbar spine pathologies. Common diagnostic steps include:

  • Physical Examination: Assessing tenderness, pain with resisted abduction, and gait abnormalities.
  • Imaging:
  • Ultrasound: Evaluates tendon integrity and bursal inflammation.
  • MRI: Identifies gluteal tendinopathy or severe bursitis.

At Alton Pain Clinic, our team uses advanced imaging techniques to provide precise diagnoses, ensuring optimal treatment outcomes.

Conservative Treatment Approaches

Initial management of GTPS typically involves conservative measures, such as:

  1. Rest and Activity Modification: Reducing activities that aggravate symptoms.
  2. Physical Therapy: Focuses on strengthening the muscles surrounding the hip and improving flexibility in the IT band.
  3. Anti-inflammatory Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can alleviate pain and inflammation.
  4. Weight Management: Reducing stress on the hip stabilisers.

Ultrasound-Guided Cortisone Injections for GTPS

For patients who do not respond adequately to conservative treatments, ultrasound-guided cortisone injections offer a minimally invasive solution. These injections deliver a combination of corticosteroids and local anaesthetic directly to the affected area, targeting inflammation and pain.

Mechanism of Action for Cortisone Injections

Corticosteroids are powerful anti-inflammatory agents that work by:

  1. Reducing Inflammation: Decreases swelling in the bursae and tendons.
  2. Alleviating Pain: Interrupts the inflammatory cascade responsible for pain signalling.
  3. Improving Mobility: Allows patients to engage in physical therapy and resume activities.

The addition of a local anaesthetic provides immediate pain relief, while corticosteroids address the underlying inflammation.

Advantages of Ultrasound Guidance

Using ultrasound for cortisone injections offers several benefits:

  • Precision: Ensures accurate delivery of medication to the inflamed structures.
  • Reduced Complications: Minimises the risk of injecting surrounding tissues.
  • Improved Comfort: Real-time visualisation enhances patient confidence and safety.

At Alton Pain Clinic, our specialists utilise state-of-the-art ultrasound technology to maximise treatment accuracy and effectiveness.

Benefits of Cortisone Injections for GTPS

Cortisone injections provide several advantages for managing GTPS, including:

  1. Targeted Relief: Directly addresses the inflamed bursae and tendons.
  2. Rapid Symptom Reduction: Patients often experience relief within days of the procedure.
  3. Non-Surgical Approach: Avoids the risks and recovery associated with surgery.
  4. Facilitates Rehabilitation: Reduces pain, enabling participation in physical therapy.

Post-Injection Care

To maximise the benefits of cortisone injections, patients should follow these guidelines:

  1. Rest the Hip: Avoid strenuous activities for 24–48 hours.
  2. Gradually Resume Activities: Reintroduce physical activities under guidance.
  3. Follow a Rehabilitation Plan: Incorporate exercises to strengthen the gluteal muscles and improve hip stability.

Long-Term Management of GTPS

While cortisone injections provide temporary relief, long-term management focuses on addressing the underlying causes of GTPS, such as muscle imbalances and activity modifications. Maintaining a healthy weight, engaging in regular low-impact exercises, and avoiding prolonged repetitive activities are crucial for preventing recurrence.
