What Is Mortons Neuroma

5/28/2017

 
Overview

plantar neuromaA neuroma is an often painful enlargement of one of your body?s nerves. Morton?s neuroma is the name used to describe nerve enlargement in your foot, particularly enlargement of one of the nerves traveling to your toes in your forefoot. Morton?s neuromas most commonly develop in one of your intermetatarsal nerves, one of many nerve branches within your foot that originated in your spine. Morton?s neuroma is more likely to affect women than men.

Causes

The exact cause of Morton?s neuroma is not known, but the choice of footwear seems be a factor. Wearing high heels (shoes with heels over 2 inches) can put extra pressure on the balls of the feet. Wearing tight or pointed toed shoes may squeeze the toes together or otherwise constrict their movement. For that reason, women are about 8 to 10 times more likely to develop Morton?s neuroma compared with men. People who are born with flat feet, high arches, or an abnormal position of the toes are more prone to developing Morton?s neuroma. This may be due to instability around the toe joints. Certain conditions that develop over time, such as bunions or hammer toes, are also associated with Morton?s neuroma. Some sports that involve running, including tennis and other racquet sports, can also increase the chance of developing Morton?s neuroma due to trauma or injury to the foot.

Symptoms

The primary symptoms include sharp, shooting pain, numbness or paresthesia in the forefoot and extending distally into the toes, typically in the region of the third and fourth toes. Symptoms are aggravated with narrow toe box shoes or those with high heels. There is usually a reduction of symptoms when walking barefoot or wearing shoes with an appropriately wide toe box. Symptoms are also aggravated with shoes that are tied too tight.

Diagnosis

You might first seek advice from your family doctor about your foot pain. He or she may refer you to a doctor or surgeon who specializes in foot disorders. Before your appointment, you may want to write a list of answers to the following questions. When did your symptoms begin? Did your symptoms begin gradually or suddenly? What type of footwear do you wear for work? Do you participate in sports? If so, what types in particular? What medications and supplements do you take regularly? Your doctor may ask some of the following questions. Is the pain worse in certain pairs of shoes? Does any type of activity ease the pain or worsen it? Are you having pain in any other part of your body?

Non Surgical Treatment

It can be helpful to perform deep stripping massage techniques along the length of the tibial nerve and the medial and lateral plantar nerves. After properly mobilizing these tissues, moving the foot and toes through a full range of motion to make sure the nerve can move freely will also be helpful. Foot pain like that occurring in Morton's neuroma, can become a debilitating and painful condition. And while massage can be helpful for this condition, it is also clear that improperly applied massage can aggravate it and make it worse. Consequently it is crucial that we use good clinical reasoning and appropriate evaluation methods to most effectively help these clients.intermetatarsal neuroma

Surgical Treatment

Operative treatment of Morton?s neuroma should be entertained only after failure of non-operative management. Standard operative treatment involves identifying the nerve and cutting (resecting) it proximal to the point where it is irritated/injured. This is usually done through an incision on the top (dorsal) aspect of the foot, although an incision on the sole (plantar) aspect of the foot can be used. Some physicians will attempt to treat Morton?s neuroma by releasing the intermetatarsal ligament, and freeing the nerve of local scar tissue. This may also be beneficial.

Prevention

The best way to prevent a neuroma is by avoiding the things that cause them. Review your risk factors. If relatives have had similar problems, or if you know that you pronate or have any problem with the mechanics of your foot, talk with a podiatric physician about the correct types of shoes and/or orthoses for you. If you are not sure whether you have such a problem, the podiatric professional can analyze your foot, your stride and the wear pattern of your shoes, and give you an honest evaluation. Remember, though, that sometimes neuromas, like other conditions, can develop for no discernible reason. With this in mind, be good to your feet, and be aware of any changes or problems. Don?t wait to report them.
