Ultrasound-Guided Cortisone Injections for Proximal Hamstring Tendinopathy

 Proximal hamstring tendinopathy is a condition that can significantly impact an individual’s ability to perform daily activities and engage in physical exercise. At Alton Pain Clinic, we focus on providing specialised care for managing musculoskeletal conditions. This detailed blog aims to provide comprehensive information about proximal hamstring tendinopathy, its anatomy, pathology, symptoms, diagnosis, and available treatment options, with a focus on ultrasound-guided cortisone injections.

Introduction to Proximal Hamstring Tendinopathy

Proximal hamstring tendinopathy is a chronic condition affecting the tendons that attach the hamstring muscles to the ischial tuberosity (the bony prominence at the bottom of the pelvis). It is typically caused by overuse or repetitive stress, leading to microtears, degeneration, and pain in the affected tendons. This condition is common among athletes, particularly runners, but can also occur in non-athletes due to prolonged sitting or sudden increases in activity levels.

Anatomy of the Hamstring Tendons

The hamstring muscles consist of three main muscles:

1. Biceps Femoris (long head and short head)
2. Semitendinosus
3. Semimembranosus

These muscles originate from the ischial tuberosity and insert into the lower leg, allowing for hip extension and knee flexion. The proximal attachment point, where the tendons connect to the pelvis, is particularly vulnerable to stress and injury, especially during activities that involve running, jumping, or prolonged sitting.

Pathology of Proximal Hamstring Tendinopathy

Proximal hamstring tendinopathy occurs when repetitive strain on the tendons surpasses their ability to heal. This condition is characterised by:

1. Tendon Degeneration: Breakdown of collagen fibres, resulting in weakened tendon structure.
2. Fibrosis: Replacement of healthy tissue with fibrous scar tissue, reducing flexibility and strength.
3. Inflammation: Localised inflammation may occur in the early stages, though chronic cases often involve degenerative changes without significant inflammation.

Symptoms of Proximal Hamstring Tendinopathy

The symptoms of proximal hamstring tendinopathy can vary but often include:

• Deep pain in the buttock, particularly near the ischial tuberosity.
• Pain that worsens during activities such as running, squatting, or prolonged sitting.
• Stiffness or tightness in the hamstring region, especially after periods of inactivity.
• Tenderness on palpation of the tendon insertion site.

Risk Factors for Proximal Hamstring Tendinopathy

Certain factors increase the likelihood of developing this condition:

• Overuse: Repetitive high-impact activities like running or cycling.
• Poor Flexibility: Limited range of motion in the hamstrings.
• Biomechanical Issues: Altered gait patterns or pelvic alignment.
• Sudden Activity Changes: Rapid increases in training intensity or duration.

Diagnosis of Proximal Hamstring Tendinopathy

Accurate diagnosis is essential for effective management. The diagnostic process typically involves:

1. Clinical History: Understanding the patient’s symptoms, activity levels, and lifestyle factors.
2. Physical Examination: Palpation of the ischial tuberosity, assessment of hamstring flexibility, and pain provocation tests such as resisted knee flexion.
3. Imaging Studies:

• Ultrasound: Provides detailed images of the tendon structure, revealing degeneration or tears.
• MRI: Useful for assessing the extent of tendon damage and ruling out other conditions.

Management of Proximal Hamstring Tendinopathy

Treatment for proximal hamstring tendinopathy focuses on reducing pain, improving function, and promoting tendon healing. Management strategies include:

1. Conservative Treatments:

• Rest: Reducing activities that aggravate symptoms.
• Physiotherapy: Strengthening and stretching exercises for the hamstrings and surrounding muscles.
• Pain Relief: Non-steroidal anti-inflammatory drugs (NSAIDs) may provide temporary relief.

2. Interventional Treatments:

• Ultrasound-Guided Cortisone Injections: Targeted delivery of corticosteroids to reduce inflammation and alleviate pain.

3. Advanced Therapies:

• Shockwave Therapy: Stimulates healing and improves blood flow to the affected area.

Ultrasound-Guided Cortisone Injections for Proximal Hamstring Tendinopathy

Cortisone injections, administered under ultrasound guidance, are a minimally invasive treatment option for managing proximal hamstring tendinopathy.

Benefits of Ultrasound Guidance

• Precision: Ensures accurate delivery of cortisone to the affected area.
• Real-Time Visualisation: Allows the clinician to avoid surrounding structures such as nerves and blood vessels.
• Improved Outcomes: Enhances the effectiveness of the treatment by targeting the site of pathology.

Mechanism of Action

Cortisone injections work by:

• Reducing Inflammation: Corticosteroids suppress inflammatory mediators, alleviating pain and swelling.
• Interrupting Pain Pathways: Decreasing the release of chemicals involved in transmitting pain signals.
• Facilitating Mobility: By reducing discomfort, cortisone helps restore normal function and allows for more effective participation in physiotherapy.

Why Choose Alton Pain Clinic for Ultrasound-Guided Cortisone Injections

At Alton Pain Clinic, we prioritise patient-centred care and employ advanced techniques to manage musculoskeletal conditions effectively. Our expertise in ultrasound-guided interventions ensures:

• Accurate and safe delivery of cortisone injections.
