Dealing With Mortons Neuroma

Overview

Morton neuromaMorton neuromas are focal areas of symptomatic perineural fibrosis around a plantar digital nerve of the foot. The abnormality is non-neoplastic and does not represent a true neuroma. It may more correctly be known as Morton?s metatarsalgia. The condition is thought to be due to chronic entrapment of the nerve by the intermetatarsal ligament. It most often occurs in middle-aged individuals and is many times more common in women than men. Approximately 30% of asymptomatic middle-aged persons have the radiological pathologic findings of a Morton?s neuroma.

Causes

Some say that this condition should not be called Morton's neuroma as, in fact, it is not actually a neuroma. A neuroma is a non-cancerous (benign) tumour that grows from the fibrous coverings of a nerve. There is no tumour formation in Morton's neuroma. The anatomy of the bones of the foot is also thought to contribute to the development of Morton's neuroma. For example, the space between the long bones (metatarsals) in the foot is narrower between the second and third, and between the third and fourth metatarsals. This means that the nerves that run between these metatarsals are more likely to be compressed and irritated. Wearing narrow shoes can make this compression worse.

Symptoms

A Morton's neuroma causes a "burning" sharp pain and numbness on the bottom of the foot in the involved area, and this pain and numbness can radiate to the nearby toes. The pain is usually increased by walking or when the ball of the foot is squeezed together and decreased with massaging. It may force a person to stop walking or to limp from the pain.

Diagnosis

Your podiatric physician will begin by taking a history of your problem. Assist him or her by describing your condition as well as you can. Keep track of when the symptoms started and how, any changes you?ve noted (whether the pain has gotten worse, or whether other symptoms have appeared as well, etc.). If you?ve noticed that certain activities or footwear make things worse or bring about additional symptoms, be sure to mention that. If you work in specific footwear, or if you participate in any certain sports, bring the shoes you use. Your doctor may be able to learn quite a lot about your condition that way!

Non Surgical Treatment

Properly resting the foot in addition to the use of appropriate footwear including, as necessary, pads and arch supports, often brings relief from Morton?s Neuroma, without resorting to surgery. A physician may also recommend anti-inflammatory drugs, cortisone injections and, should the condition fail to resolve itself, surgery.Morton

Surgical Treatment

If other therapies have not worked it may be necessary to perform surgery. As surgery may result in permanent numbness in the affected toe, doctors ten to use this procedure as a last resort. However, in most cases surgery is extremely effective. The patient usually receives a local anesthetic. Surgery involves either removing the nerve, or removing the pressure on the nerve. Two surgical approaches are possible. The dorsal approach, the surgeon makes an incision on the top of the foot, allowing the patient to walk soon after surgery, because the stitches are not on the weight-bearing side of the foot. The plantar approach, the surgeon makes an incision on the sole of the foot. In most cases the patient will be in crutches for about three weeks. The resulting scar may make walking uncomfortable. However, with this approach the neuroma can be reached easily and resected without cutting any structures. There is a small risk of infection around the toes after surgery.
