Definition

Morton's neuroma is an inflammation of the nerves in the foot that go to the toes. Although the name includes the word “neuroma,” it is not really a tumor. It can affect any of the toes in the foot. However, it most often affects the nerves that run between the third and fourth or second and third toes. It is also known as an interdigital neuroma.

Parts of the Body Involved

  • Foot and toes

Reasons for Procedure

The procedure is done to alleviate pain and tingling caused by the inflammation.

Risk Factors for Complications During the Procedure

  • Smoking
  • Poor nutrition
  • Recent or chronic illness
  • Use of certain medications
  • Allergy to anesthesia
  • Diabetes
  • Bleeding disorders
  • Circulatory disorders

What to Expect

Prior to Procedure

  • Medical history
  • Physical exam
  • X-ray (done at times)

During Procedure

Anesthesia and/or sedation will be administered.

Anesthesia

Local or general anesthesia will be used.

Description of the Procedure

A small incision is made on the top of the foot in the skin between the two toes that are affected by the neuroma. The neuroma is located and removed by cutting the nerve. The incision is closed with stitches and a bandage is applied. The stitches are usually removed in the doctor's office 7-10 days after the surgery.

After Procedure

How Long Will It Take?

The procedure typically takes less than one hour.

Will It Hurt?

Anesthesia prevents pain during the procedure. You may have some pain during recovery, but you will be given pain medication to relieve this discomfort.

Possible Complications

  • Recurrence of pain
  • Bleeding
  • Infection
  • Recurrence of the condition

Average Hospital Stay

This procedure is usually done on an outpatient basis.

Postoperative Care

  • Keep the surgical area clean and dry.
  • Use compression and ice to prevent swelling, as directed by your doctor.
  • Keep your foot elevated.
  • Take antibiotics to prevent infection.
  • Take pain medication as directed by your doctor.

Outcome

After Morton’s neuroma removal, about 80% of patients have good pain relief.

You'll gradually be able to return to full activities within 3-6 weeks. The small area where the nerve was removed is likely to remain numb. Your doctor may prescribe orthotics (supporting devices for your foot) to help prevent the condition from returning.
