A Non-Surgical Option for Carpal Tunnel & Nerve Entrapment
An ultrasound-guided injection procedure that uses fluid to separate a compressed or entrapped peripheral nerve from surrounding scar tissue or fascia — restoring normal nerve gliding and relieving pain, numbness, and tingling. Used for carpal tunnel syndrome, cubital tunnel syndrome, tarsal tunnel syndrome, meralgia paresthetica, and other nerve entrapment conditions.

Freeing a Nerve From Surrounding Tissue
Peripheral nerves can become compressed or entrapped by surrounding scar tissue, thickened fascia, or narrow anatomical tunnels — as in carpal tunnel syndrome at the wrist, cubital tunnel syndrome at the elbow, tarsal tunnel syndrome at the ankle, and meralgia paresthetica at the thigh. This entrapment restricts the nerve's normal gliding motion, driving pain, numbness, tingling, and weakness in the area it supplies.
Nerve hydrodissection uses precisely placed fluid, guided in real time by ultrasound, to mechanically separate the nerve from the tissue restricting it — relieving pressure and restoring its normal mobility.
Low Risk, Precisely Targeted, and Done in the Office
For many patients with nerve entrapment, this is a reasonable step before considering a surgical nerve release.
Precisely Targeted
Every hydrodissection is performed under real-time ultrasound guidance, so fluid is delivered exactly where the nerve is restricted — not a blind injection.
Low Risk
Performed with fluid and a local anesthetic under ultrasound guidance — no incision, and a low risk of complications.
Done Right in the Office
No surgery, no sedation, and no downtime — the entire procedure is performed at our Newport Beach office in a single visit.
Can Delay or Avoid Surgery
Many cases of nerve entrapment respond well to hydrodissection and neuromodulation, helping patients avoid or delay a surgical nerve release.
100% ultrasound-guided. Every nerve hydrodissection procedure at OCMSK is performed under real-time ultrasound guidance, so the injection is delivered precisely to the site of nerve entrapment.
Where This Treatment Fits Into Your Care
Carpal Tunnel Syndrome ›
Compression of the median nerve at the wrist, causing hand numbness, tingling, and weakness.
Cubital Tunnel Syndrome ›
Compression of the ulnar nerve at the elbow, causing numbness and tingling into the ring and small fingers.
Tarsal Tunnel Syndrome ›
Compression of the posterior tibial nerve at the ankle, causing foot pain, numbness, and tingling.
Meralgia Paresthetica ›
Compression of the lateral femoral cutaneous nerve, causing numbness and burning on the outer thigh.
This list is not exhaustive. We evaluate and treat many other nerve entrapment conditions — contact us to schedule a consultation for a proper diagnosis and treatment options.
Common Questions
What is nerve hydrodissection? +
It's a precise, ultrasound-guided injection that separates an entrapped nerve from surrounding scar tissue or fascia using an injected fluid, restoring its normal gliding motion and relieving pressure.
What conditions is it used for? +
Most commonly carpal tunnel syndrome, cubital tunnel syndrome, tarsal tunnel syndrome, and meralgia paresthetica — as well as other peripheral nerve compression or entrapment syndromes.
Can this help me avoid surgery? +
Many cases of nerve compression, such as carpal tunnel or cubital tunnel syndrome, respond well to ultrasound-guided hydrodissection and neuromodulation, helping patients avoid or delay a surgical nerve release. Response varies by severity — we'll review your ultrasound findings at your consultation.
Is PRP ever combined with nerve hydrodissection? +
For select nerve injuries, we add platelet-rich plasma to the hydrodissection to further support nerve healing. We'll let you know if this is a good fit for your case.
Why does ultrasound guidance matter? +
Blind injections frequently miss their target. Every procedure at OCMSK is performed under real-time ultrasound guidance, so the fluid is delivered to the exact site of nerve entrapment.
Is this covered by insurance? +
Yes. With an accepted plan (Cigna, Anthem Blue Cross, Aetna, United Healthcare, or Medicare PPO), nerve hydrodissection is billed to your insurance at $0 out-of-pocket cost to you. Self-pay patients are welcome with transparent, accessible rates — see our pricing page for details.
What happens at the first visit? +
A full history and physical exam plus a diagnostic ultrasound of the affected nerve — so you leave with an accurate diagnosis, an understanding of every factor contributing to it, and a clear treatment plan.
