Peripheral artery disease (PAD), or peripheral arterial disease, is a circulatory problem in which there is a reduction of blood flow to the limbs due to narrowed arteries. When peripheral artery disease develops, the extremities do not receive enough blood flow; this may cause symptoms to develop such as claudication, or leg pain when walking. The legs are the most common site of peripheral artery disease.

Claudication, or leg pain when walking, is one of several symptoms that can develop due to peripheral artery disease. Other symptoms caused by the disease include painful cramping in the hips, thighs, or calves after certain activities; leg numbness or weakness; coldness in the lower leg or foot; sores on the lower extremities that do not heal; hair loss on the lower extremities; and a missing or weak pulse in the lower extremities. In more severe cases, pain may even occur when the body is at rest or when lying down.

Peripheral artery disease is typically caused by atherosclerosis, a condition in which fatty deposits build up in the arterial walls and reduce blood flow. Smoking, diabetes, obesity, high blood pressure, and high cholesterol are some of the risk factors for peripheral artery disease.

If you are experiencing pain, numbness, or other symptoms in the lower extremities, see your healthcare professional immediately. Diagnosed peripheral artery disease can be treated with various medications, angioplasty and surgery, exercise programs, or alternative medicine. It is important to consult a healthcare professional to determine the best treatment for you.

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. 

Neuropathy is a condition in which the nerves in the body become damaged from a number of different illnesses. Nerves from any part of the body, including the foot, can be damaged. There are several forms of neuropathy including peripheral neuropathy, cranial neuropathy, focal neuropathy, and autonomic neuropathy. Furthermore there is also mononeuropathy and polyneuropathy. Mononeuropathies affect one nerve while polyneuropathies affect several nerves. Causes of neuropathy include physical injury, diseases, cancers, infections, diabetes, toxic substances, and disorders. It is peripheral neuropathy that affects the feet.

The symptoms of neuropathy vary greatly and can be minor such as numbness, sensation loss, prickling, and tingling sensations. More painful symptoms include throbbing, burning, freezing, and sharp pains. The most severe symptoms can be muscle weakness/paralysis, problems with coordination, and falling.

Podiatrists rely upon a full medical history and a neurological examination to diagnose peripheral neuropathy in the foot. More tests that may be used include nerve function tests to test nerve damage, blood tests to detect diabetes or vitamin deficiencies. Imaging tests, such as CT or MRI scans, might be used to look for abnormalities, and finally nerve or skin biopsies could also be taken.

Treatment depends upon the causes of neuropathy. If the neuropathy was caused by vitamin deficiency, diabetes, infection, or toxic substances, addressing those conditions can lead to the nerve healing and sensation returning to the area. However if the nerve has died, then sensation may never come back to the area. Pain medication may be prescribed for less serious symptoms. Topical creams may also be tried to bring back sensation. Electrical nerve stimulation may be used for a period of time to stimulate nerves. Physical therapy can strengthen muscle and improve movement. Finally surgery might be necessary if pressure on the nerve is causing the neuropathy.

If you are experiencing sensation loss, numbness, tingling, or burning sensations in your feet, you may be experiencing neuropathy. Be sure to talk to a podiatrist to be diagnosed right away.

Sesamoiditis is a condition in which the sesamoid bones in the forefoot become inflamed from physical activity. Sesamoid bones are bones that are not connected to other bones but are located in tendons or muscle. Two of these sesamoid bones are very small and located on the underside of the foot near the big toe. Athletes such as runners, baseball and football players, and dancers are likely to experience sesamoiditis. Those with high arched feet, flat feet, or runners who run on the ball of their foot are also prone to suffer from sesamoiditis.

Symptoms include pain or throbbing on the ball of the foot near the big toe. The pain generally starts with a mild throbbing but gradually builds up to shooting pain. Bruising, swelling, and redness are possible, but in most cases, these symptoms are not present. However, moving the big toe can result in pain and difficulty.

To conduct a diagnosis, the podiatrist will examine the ball of the foot and big toe. They will look for any outliers and check the movement of the toe. X-rays will be taken to rule out any other conditions and ensure that it is sesamoiditis.

Treatment for sesamoiditis is generally mild and includes rest, anti-inflammatory and pain medication, and ice treatments to deal with the swelling and pain. Orthotics may be needed with people who have flat or high arched feet to relieve pressure off the bones. In some cases the toe will be taped and immobilized to allow healing. The podiatrist may also decide to use a steroid injection to help with swelling as well. If you have sesamoiditis, you shouldn’t engage in any intensive activity, as it may inflame the area and worsen your pain. If the sesamoid bone has fractured, surgery may be required to remove the sesamoid bone.

If you are suffering from sesamoiditis or are experiencing symptoms similar to sesamoiditis, you should stop all physical activity that puts strain on the area. Furthermore you should see a podiatrist for a diagnosis to see if you have sesamoiditis.
