Overview

intermetatarsal neuromaA neuroma develops when a nerve is compressed, injured or pinched, causing swelling and pain. A neuroma in the area between the third and fourth toes, or between the second and third toes, is known as a Morton?s neuroma. Morton?s neuroma causes sharp, burning pain and numbness in the toes and foot. You may feel like you?ve stepped on a tiny hot coal and can?t get rid of it. At the same time, you?ll have the disconcerting experience of not being able to feel your toes. Sometimes the nerve tissue becomes so thickened you can feel or see a lump.

Causes

There are many reasons to develop a neuroma. Improper shoe gear is probably the most likely cause. Repetitive activity and excessive pressure on the ball of the foot are common. Heredity and genetic factors may also be involved. In many cases the structure of the foot may predispose the condition. Associated conditions that may cause neuroma include: bunion, hammer toes, ligament laxity, and/or a tight calf muscle. Some patients may have thinning of the fat pad on the ball of the foot, which may result in increased pressure of the nerves. Tight pointy shoes (and high heels) without padding may induce pain in the ball of the foot. Neuroma may occur suddenly, or develop over time.

Symptoms

Symptoms of interdigital neuroma typically manifest as a sharp, burning or tingling sensation in the forefoot. The pain radiates toward the lesser toes and is aggravated by shoe wear. The pain is relieved when the shoe is removed and the forefoot is massaged. Sometimes the symptoms involve specific toes.

Diagnosis

During the exam, your doctor will press on your foot to feel for a mass or tender spot. There may also be a feeling of "clicking" between the bones of your foot. Some imaging tests are more useful than others in the diagnosis of Morton's neuroma. Your doctor is likely to order X-rays of your foot, to rule out other causes of your pain such as a stress fracture. Ultrasound. This technology uses sound waves to create real-time images of internal structures. Ultrasound is particularly good at revealing soft tissue abnormalities, such as neuromas. Magnetic resonance imaging (MRI). Using radio waves and a strong magnetic field, an MRI also is good at visualizing soft tissues. But it's an expensive test and often indicates neuromas in people who have no symptoms.

Non Surgical Treatment

The first step in treating Morton's Neuroma is to select proper footwear. Footwear with a high and wide toe box (toe area) is ideal for treating and relieving the pain. The next step in treatment is to use an orthotic designed with a metatarsal pad. This pad is located behind the ball-of-the-foot to unload pressure, and relieve the pain caused by the neuroma.

Surgical Treatment

Interdigital neurectomy (removal of the diseased nerve) in right hands, should give satisfactory results almost all the time. Some of the reasons behind failure is when not enough nerve is dissected, mistakes in initial diagnosis, or bad handling of adjacent nerves, tendons and joint capsules during the operation. It is very common and acceptable to have some numbness in the area where the nerve used to be. This never causes any discomfort and often gets better in few years. It is crucial to address the biomechanical pathologies underlying the impingement of the nerve during and after the surgery.

Prevention

Wearing proper footwear that minimizes compression of the forefoot can help to prevent the development of and aggravation of a Morton's neuroma.
