Dealing With Mortons Neuroma

Overview

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.

Causes

There are a number of common causes for Morton?s Neuroma, (though the condition can arise spontaneously for reasons still unknown). The Neuroma often occurs in response to irritation, pressure or traumatic injury to one of the digital nerves leading to the toes. A thickening of nerve tissue results as part of the body?s response to the irritation or injury. Abnormal foot movement used to compensate for bunions, hammertoes, flatfeet and other conditions can lead to irritation and development of Morton?s Neuroma. Pronation of the foot may cause the heads of the metatarsal bones to rotate slightly, thereby pinching the nerve running between the metatarsal heads. Chronic pressure or pinching causes the nerve sheath to enlarge, becoming increasingly squeezed, producing worsening pain over time, if not addressed. Morton?s Neuroma can be exacerbated when tight shoes providing little room for the forefoot are worn. Activities which over-pronate the foot (such as walking barefoot in sand) may increase the pain associated with Morton?s Neuroma, as will any high-impact activity, such as jogging.

Symptoms

Pain is usually increased by forefoot weight bearing activities (such as running), with narrow-fitting footwear, or with high heeled shoes. It is usually painful to firmly touch the affected region and, in chronic cases, pain and sometimes an audible click, may be heard when squeezing the foot and toes together with the hand. Often a localized area of swelling may be evident at the site of injury.

Diagnosis

Morton?s neuroma can be identified during a physical exam, after pressing on the bottom of the foot. This maneuver usually reproduces the patient?s pain. MRI and ultrasound are imaging studiesthat can demonstrate the presence of the neuroma. An x-ray may also be ordered to make sure no other issues exist in the foot. A local anesthetic injection along the neuroma may temporarily abolish the pain, and help confirm the diagnosis.

Non Surgical Treatment

Orthotics and corticosteroid injections are widely used conservative treatments for Morton?s neuroma. In addition to traditional orthotic arch supports, a small foam or fabric pad may be positioned under the space between the two affected metatarsals, immediately behind the bone ends. This pad helps to splay the metatarsal bones and create more space for the nerve so as to relieve pressure and irritation. It may however also elicit mild uncomfortable sensations of its own, such as the feeling of having an awkward object under one’s foot. Corticosteroid injections can relieve inflammation in some patients and help to end the symptoms. For some patients, however, the inflammation and pain recur after some weeks or months, and corticosteroids can only be used a limited number of times because they cause progressive degeneration of ligamentous and tendinous tissues.

Surgical Treatment

Surgery for Morton’s neuroma is usually a treatment of last resort. It may be recommended if you have severe pain in your foot or if non-surgical treatments haven’t worked. Surgery is usually carried out under local anaesthetic, on an outpatient basis, which means you won’t need to stay in hospital overnight. The operation can take up to 30 minutes. The surgeon will make a small incision, either on the top of your foot or on the sole. They may try to increase the space around the nerve (nerve decompression) by removing some of the surrounding tissue, or they may remove the nerve completely (nerve resection). If the nerve is removed, the area between your toes may be permanently numb. After the procedure you’ll need to wear a special protective shoe until the affected area has healed sufficiently to wear normal footwear. It can take up to four weeks to make a full recovery. Most people (about 75%) who have surgery to treat Morton’s neuroma have positive results and their painful symptoms are relieved.

Hammer Toe Deformity

Overview

Hammer toes are classified based on the mobility of the toe joints. There are two types. Flexible and rigid. In a flexible Hammer toes, the joint has the ability to move. This type of hammer toe can be straightened manually. A rigid hammer toe does not have that same ability to move. Movement is very limited and can be extremely painful. This sometimes causes foot movement to become restricted leading to extra stress at the ball-of-the-foot, and possibly causing pain and the development of corns and calluses.

Causes

As described above, the main reason people develop hammertoes is improper footwear, or footwear that is too short for the toes. Shoes that do not allow our toes to lie flat are the biggest cause of hammertoes, though there are others, including genetics, injury or trauma in which the toe is jammed or broken. Diseases that affect the nerves and muscles, such as arthritis. Abnormal foot mechanics due to hammertoe nerve or muscle damage, causing an imbalance of the flexor and extensor tendons of the toe. Systematic diseases such as arthritis can also lead to problems such as hammertoe. Some people are born with hammertoes, while others are more prone to developing the condition due to genetics. If you have ever broken a toe, you know there is not much that can be done for it. It is one of the only bones in the body that heals without the use of a cast. A broken toe may be splinted, however, which may help prevent a hammertoe from forming.

Symptoms

Hammer toe is often distinguished by a toe stuck in an upside-down ?V? position, and common symptoms include corns on the top of your toe joint. Pain at the top of a bent toe when you put on your shoes. Pain when moving a toe joint. Pain on the ball of your foot under the bent toe. Corns developing on the top of the toe joint. It is advisable to seek medical advice if your feet hurt on a regular basis. It is imperative to act fast and seek the care of a podiatrist or foot surgeon. By acting quickly, you can prevent your problem from getting worse.

Diagnosis

The earlier a hammertoe is diagnosed, the better the prognosis and treatment options. Your doctor will be able to diagnose your hammertoe with a simple examination of the foot and your footwear. He or she may take an x-ray to check the severity of the condition. You may also be asked about your symptoms, your normal daily activities, and your medical and family history.

Non Surgical Treatment

A number of approaches can be undertaken to the manage a hammer toe. It is important that any footwear advice is followed. The correct amount of space in the toe box will allow room for the toes to function without excessive pressure. If a corn is present, this will need to be treated. If the toe is still flexible, it may be possible to use splints or tape to try and correct the toe. Without correct fitting footwear, this is often unsuccessful. Padding is often used to get pressure off the toe to help the symptoms. If conservative treatment is unsuccessful at helping the symptoms, surgery is often a good option.

Surgical Treatment

Surgery is used when other types of treatment fail to relieve symptoms or for advanced cases of hammertoe. There are several types of surgeries to treat hammertoe. A small piece of bone may be removed from the joint (arthroplasty). The toe joint may be fused to straighten it (arthrodesis). Surgical hardware, such as a pin, may be used to hold the bones in place while they heal. Other types of surgery involve removing skin (wedging) or correcting muscles and tendons to balance the joint.

Prevention

There should be at least one-half inch between the tip of your longest toe and the front of the shoe. Never buy shoes that feel tight and expect them to stretch with wearing. If you have prominent areas on your feet such as hammertoes and bunions, avoid shoes with a lot of stitching or multiple pieces of fabric, as these stitched areas tend not to stretch to accommodate various toe deformities.
