A neuroma is a thickening of nerve tissue and can develop throughout the body.  In the foot, the most common neuroma is a Morton’s neuroma; this typically forms between the third and fourth toes.  The thickening of the nerve is typically caused by compression and irritation of the nerve; this thickening can in turn cause enlargement and, in some cases, nerve damage.

Neuromas can be caused by anything that causes compression or irritation of the nerve.  A common cause is wearing shoes with tapered toe boxes or high heels that force the toes into the toe boxes.  Physical activities that involve repeated pressure to the foot, such as running or basketball, can also create neuromas.  Those with foot deformities, such as bunions, hammertoes, or flatfeet, are more likely to develop the condition.

Symptoms of Morton’s neuroma include tingling, burning, numbness, pain, and the feeling that either something is inside the ball of the foot or that something in one’s shoe or sock is bunched up.  Symptoms typically begin gradually and can even go away temporarily by removing one’s shoes or massaging the foot.  An increase in the intensity of symptoms correlates with the increasing growth of the neuroma.

Treatment for Morton’s neuroma can vary between patients and the severity of the condition.  For mild to moderate cases, padding, icing, orthotics, activity modifications, shoe modifications, medications, and injection therapy may be suggested or prescribed.  Patients who have not responded successfully to less invasive treatments may require surgery to properly treat their condition.  The severity of your condition will determine the procedure performed and the length of recovery afterwards.

In most cases, foot surgery is often chosen as the last available option for conditions that have otherwise been unsuccessfully treated. Surgery may be necessary for several reasons, including the removal of foot deformities (e.g. bone spurs or bunions), arthritis problems, reconstruction due to injury, and congenital malformations (e.g. club foot or flat feet). Regardless of one’s age, foot surgery may be the only successful option for treatment for certain conditions.

The type of surgery one undergoes depends on the type of foot condition the patient has. For the removal of a bunion growth, a bunionectomy is necessary. If the bones in the feet need to be realigned or fused together, a surgical fusion of the foot is needed. For pain or nerve issues, a patient may require surgery in which the tissues surrounding the painful nerve are removed. Initially, less invasive treatments are generally attempted; surgery is often the last measure taken if other treatments are unsuccessful.

While in many cases surgery is often deemed as the final resort, choosing surgery comes with certain benefits. The associated pain experienced in relation to the particular condition is often relieved with surgery, allowing patients to quickly resume daily activities. The greatest benefit, however, is that surgery generally eliminates the problem immediately.

Podiatry history has shown that foot treatments continue to evolve over time. In the field of foot surgery, endoscopic surgery is just one of the many advanced forms of surgery. As technology vastly improves so too will the various techniques in foot surgery, which already require smaller and smaller incisions with the use of better and more efficient tools. Thanks to such innovations, surgery is no longer as invasive as it was in the past, allowing for faster and easier recoveries. 

There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis, among others.

In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.

Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.

There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.

Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.

All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.

A plantar fibroma is a knot in the arch of the foot. It can cause pain when repeated pressure is applied by walking barefoot or wearing tight shoes. While plantar fibromas can appear in anyone, men who are middle-aged or older are said to be more susceptible. The main symptom of a plantar fibroma is a firm lump on the arch of the foot. If there is pain, it can be intensified by putting pressure on the nodule. The lump can stay one size or grow larger. You may have one or more fibromas in the feet and there tends to be a high incidence of recurring plantar fibromas.  Generally, a plantar fibroma can be treated without surgery. Treatment might include steroid injections to help shrink the lump, orthotics to help redistribute weight away from the nodule, plantar fascia stretching, or physical therapy to help use anti-inflammatory medication on the lump. If a lump grows larger or more painful, a podiatrist can be consulted to confirm the diagnosis. The doctor will palpate the lump and this may cause pain that can be felt all the way to the toes. An X-ray, MRI, or biopsy might be done if further evaluation is necessary. A lump in the arch of the foot might be something other than a plantar fibroma, such as cysts, nerve or fatty tumors, swollen tendons, or an infection in the foot. It is important to see a podiatrist for proper diagnosis and treatment of plantar fibromas.

Limb salvage is a procedure that involves saving a lower extremity from amputation. In podiatry, limb amputation often occurs as a result of diabetes. The fundamental goal of limb salvage is to restore and maintain stability and movement of the affected lower extremity.

The procedure typically involves removing the diseased tissue and a small portion of the surrounding healthy tissue, as well as the removal of any affected bone if necessary. If bone is removed it is then replaced with prostheses, or synthetic metal rods or plates, or grafts from either the patient’s body or a donor. Limb salvage is typically the preferred choice of procedure over amputation, as the procedure preserves both the patient’s appearance and allows for the greatest possible degree of function in the affected limb.

Upon diagnosis and determining that limb salvage is the appropriate treatment, the podiatrist may enlist the help of a physical and/or occupational therapist to prepare the patient for surgery by introducing various muscle-strengthening, walking, and range of motion exercises. Such exercises may be continued as rehabilitation post-procedure.
