Key Points About Nerve Hydrodissection of the Ankle

  • Nerve hydrodissection of the ankle is a unique, minimally invasive therapy to treat nerve entrapment.
  • The goal of nerve hydrodissection is to alleviate pain and allow you to return to your daily activities.
  • Patients who have an entrapped nerve as a result of conditions such as rheumatoid arthritis may be candidates for nerve entrapment.
  • In many cases, only one treatment is necessary to relieve pain, but in some cases, you will need three to six treatments to experience complete pain relief.

Nerve hydrodissection is a minimally invasive treatment for patients who are experiencing symptoms of nerve entrapment.

Nerve entrapment is a common condition that develops when nerves become compressed and restricted due to trauma, injury, or overuse. When this occurs, you may experience pain, numbness, tingling, or other symptoms.  

During nerve hydrodissection, fluid is injected around the nerves to release adhesions from nearby structures.

A nerve hydrodissection can alleviate pain enabling nerves to regenerate.

Candidates for a Nerve Hydrodissection of the Ankle

Nerve hydrodissection is often used to treat nerve compression that occurs as a result of rheumatoid arthritis. Nerve compression in the ankle is known as Tarsal Tunnel Syndrome and is characterized by burning or electrical sensation in your first three toes and heel. 

Conditions treated with nerve hydrodissection include:

  • Scar neuropathy.
  • Morton's neuroma.
  • Thoracic outlet syndrome.
  • Nerve entrapment syndrome.

Risks Associated with a Nerve Hydrodissection of the Ankle

While complications are rare with a nerve hydrodissection of the ankle, they can occur. Complications may include:

  • Nerve damage.
  • Reaction to the injection.
  • Bleeding at the incision site.
  • Mild discomfort at the incision site.

Preparation for a Nerve Hydrodissection of the Ankle

You do not need to do any special preparations before a hydrodissection of the ankle. Your care team will walk you through the process to make you feel comfortable. You will go back to work or home after each injection.

What to Expect During Nerve Hydrodissection of the Ankle

Nerve hydro dissection of the ankle is an outpatient procedure that can be performed in a clinic. While anesthesia is not generally necessary, your orthopedic doctor may apply a local numbing agent to your ankle before the injection. 

The injection will be either by platelet-rich plasma (PRP) or a 5 percent dextrose solution (D5W) that is injected into the painful area.

During the procedure, your care team will:

  • Clear the skin around the ankle.
  • Use ultrasound imaging to guide the needle into the area around the nerve.
  • When the needle is in the correct place, your provider will slowly release the PRP or D5W fluid.

The fluid will relieve the pressure on the nerves. As the nerves heal, your pain and numbness will improve. Hydrodissection of the ankle provides long-lasting relief so you can get back to your normal activities.

Duration of Nerve Hydrodissection of the Ankle Treatment

You may need three to six injections to feel full symptom relief. Injections can be scheduled weekly.
