What are the causes of Achilles tendinopathy?
The Achilles tendon, the largest and strongest tendon in the human body, is crucial for walking, running, and jumping, making it vulnerable to injuries. Some common causes of tendonopathy include:
- Repetitive activities: Activities involving repetitive movements of the foot and ankle, such as running, jumping, or dancing, can put pressure on the Achilles tendon, leading to its inflammation.
- Sudden increase in activity: A drastic increase in the intensity, duration, or frequency of exercise without proper training can overload the Achilles tendon and cause injury.
- Improper footwear: Shoes that do not provide adequate support or cushioning against shocks can contribute to the development of tendonopathy by increasing the pressure on the tendon during movement.
What are the symptoms of Achilles tendinopathy?
The symptoms of Achilles tendinopathy can vary in severity but generally include:
- Pain: Pain in the tendon area, especially in the morning or after a period of rest, is a common symptom.
- Swelling: Swelling along the Achilles tendon, especially near the heel, may occur due to inflammation.
- Difficulty in movement: Pain and discomfort may worsen with activity, making walking, running, or climbing stairs difficult.
- Reduced range of motion: Decreased flexibility and range of motion in the ankle may occur as a result of Achilles tendonopathy.
What is the role of ultrasound in cases of Achilles Tendinopathy?
Ultrasound is the preferred imaging method for tendons, and the role of New Ultrasound Techniques is particularly critical for the diagnosis and management of Achilles tendinopathy.
Research has shown that in cases of Achilles tendinopathy, there is increased microvascularization in the area, as well as neovascularization, meaning the formation of new blood vessels, which is associated with pain, reduced function, and the chronic nature of the condition.
Newer Ultrasound Techniques allow for the visualization of blood flow in small vessels and the detection of possible neovascularization, enabling a specialized Radiologist to diagnose and evaluate the condition with absolute accuracy, as well as to perform Ultrasound-guided Injection Therapy, where appropriate.
Treatment of Achilles Tendinopathy: High-Volume Image-Guided Injection (HVIGI)
High-Volume Image-Guided Injection (HVIGI) is a modern therapeutic technique for cases of Achilles tendonitis that aims to disrupt the neovascularization affecting the tendon.
HVIGI therapy involves ultrasound-guided injection of a mixture of local anaesthetic and saline between the tendon and the paratendon or between the tendon and Kager’s fat pad, eliminating neovascularization, alleviating pain, and improving tendon function.
Ultrasound-guided HVGI is a safe, minimally invasive treatment for patients with Achilles tendinopathy, which can be an alternative to surgical intervention. The role of Ultrasound Guidance during HVGI treatment is critical for the safety of the procedure as well as for the precise placement of the injection in the anatomical area affected.
Conclusion
Due to the importance of the Achilles tendon in body mobility, Achilles tendinopathy can significantly impact the patient's daily life. High-Volume Image-Guided Injection (HVIGI) represents an innovative option for the treatment of Achilles tendinopathy, as it relieves inflammation by eliminating neovascularization around the tendon, without the use of cortisone or other drugs. Minimally invasive, ultrasound-guided therapies continue to evolve, offering improved therapeutic outcomes, reduced recovery time, and the potential to avoid surgical intervention.
