Precise ultrasound-guided procedures to treat injuries and conditions with effectiveness and safety.
Ultrasound-guided percutaneous carpal tunnel release ("Carpal Tunnel Hydrodissection") is an innovative and minimally invasive procedure designed to treat carpal tunnel syndrome, a condition that causes pain, tingling, and weakness in the hand and fingers. This technique offers an effective solution to relieve symptoms and restore functionality to the affected limb. without the need for surgery..
Carpal tunnel syndrome occurs when the median nerve, which passes through the carpal tunnel in the wrist, becomes compressed due to inflammation or factors such as overuse, trauma, or medical conditions. Symptoms include pain, tingling, and weakness, which can interfere with daily activities and quality of life.
This procedure involves a small "puncture" in the skin, through which a needle is placed inside the carpal tunnel, guided by ultrasound. A high volume of fluid is then instilled to "widen the carpal tunnel" and "release" the median nerve, relieving pressure around the nerve. Ultrasound is used to guide the physician during the procedure, ensuring precise targeting of the compression and minimising the risk of injury to adjacent structures.
Ultrasound-guided percutaneous carpal tunnel release is recommended for patients with persistent symptoms of carpal tunnel syndrome who have not found relief with conservative treatments.
Everything You Need to Know
Carpal tunnel syndrome is a compression neuropathy of the median nerve at the wrist. It typically causes tingling, numbness, and pain in the hand—especially in the thumb, index finger, and middle finger—with symptoms often becoming more severe at night.
Ultrasound-guided median nerve hydrodissection is a minimally invasive procedure that involves injecting fluid (saline solution and/or other therapeutic agents) around the median nerve under ultrasound guidance. This technique helps separate the nerve from surrounding tissues, release adhesions, and reduce compression without the need for surgery.
Hydrodissection is less invasive than surgery, requires no incision, allows for a faster recovery, and may be an effective alternative for patients with mild to moderate carpal tunnel syndrome or for those who wish to delay or avoid surgery.
Yes. When performed by an experienced physician under ultrasound guidance, the risk of injury to the median nerve or adjacent blood vessels is minimal. It is an outpatient procedure that does not require general anesthesia.
No. In advanced cases, particularly when there is significant muscle weakness or severe abnormalities on nerve conduction studies, surgical decompression may be the most appropriate treatment. A thorough clinical evaluation, together with electrodiagnostic testing (nerve conduction studies and electromyography), is essential to determine the best treatment option.
Many patients report improvement within days to weeks after the procedure. Individual responses vary, and in some cases, more than one treatment session may be required.
