Entrapped Nerve Hydrodissection

Entrapped nerve hydrodissection is a minimally invasive non-surgical procedure that uses ultrasound technology to alleviate symptoms of compressed nerve disorders. Compressed nerve disorders result when direct pressure is placed on a single nerve, producing numbness, pain, weakness or a tingling sensation. Compressed nerve disorders may be caused by a variety of factors, including health conditions such as diabetes or rheumatoid arthritis, injury, pregnancy or obesity. Entrapped nerve hydrodissection is generally recommended as a treatment for compressed nerve disorders after conservative treatments have been unsuccessful at relieving painful symptoms.

Candidates for Entrapped Nerve Hydrodissection

This procedure is frequently used to treat carpal tunnel syndrome, a common nerve compression disorder, which occurs when the median nerve in the wrist becomes pinched. In addition, entrapped nerve hydrodissection may also benefit patients with:

  • Cubital tunnel syndrome
  • Sural nerve entrapment

Conservative treatment methods such as anti-inflammatory medications or corticosteroid injections are often initially recommended as treatment for compressed nerve disorders. If these treatments are ineffective, surgery may also be recommended. Entrapped nerve hydrodissection is an effective alternative for patients who do not want to or cannot undergo invasive surgery.

The Entrapped Nerve Hydrodissection Procedure

Entrapped nerve hydrodissection is a non-invasive procedure and no incisions are made. Instead, entrapped nerve hydrodissection implements the use of ultrasound technology to treat the condition. The procedure is typically performed in a doctor's office and lidocaine may be administered as an anesthetic. During the procedure the physician places a needle, guided by an ultrasound device, to the precise site of the nerve entrapment.. A saline solution, containing salt and water, is injected between the affected nerve and the ligaments that are placing pressure on it. This infusion of fluid helps to separate the ligament from the nerve, reducing the direct pressure and relieving symptoms.

Recovery from the Entrapped Nerve Hydrodissection Procedure

Entrapped nerve hydrodissection is considered a safe and effective form of treatment. Following the procedure, most patients will notice a significant, and rapid, decrease in the level of pain and numbness previously experienced. Complications are rare, but may include swelling at the injection site and infection. Patients can usually return to their normal activities the day after the procedure.

Results of the Entrapped Nerve Hydrodissection Procedure

Pain relief is often noticeable almost immediately following the injection. The procedure can be very effective for managing pain and other symptoms related to carpal tunnel syndrome or other nerve compression disorders.

While entrapped nerve hydrodissection commonly provides significant symptom relief, the results may not be permanent. Patients who continue to experience painful symptoms following the injection, may receive a second injection, but it may be administered approximately six months after the initial injection. For patients who continue to experience persistent pain related to a nerve compression disorder, despite receiving injections, surgery may eventually be necessary.
