In foot care, vascular testing may be required in the diagnosing and treatment of certain podiatric conditions. Vascular testing is particularly relevant for patients with high-risk diabetes, poor circulation, peripheral artery disease (PAD), and chronic venous insufficiency (CVI). Procedures typically involve the examination of blood vessels throughout the body for blockages or buildup.
Vascular testing is very important for the diagnosis of various conditions, including peripheral artery disease and chronic venous insufficiency, as these conditions can greatly affect one’s quality of life and cause pain in the lower limbs. Circulatory problems in the feet and ankles can reflect issues throughout the body, making testing of the blood vessels pertinent.
Testing methods vary between practitioners and can be specific to certain foot and ankle problems. Modern technology has brought about the ability to perform vascular testing using non-invasive methods, such as the cuff-based PADnet testing device. This device records the Ankle-Brachial Index (ABI)/Toe-Brachial Index (TBI) values and Pulse Volume Recording (PVR) waveforms. Contact your podiatrist to determine what vascular testing is available for your needs.
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.
Hammertoes are painful deformities that frequently form on the second, third, or fourth toe. The condition is often caused by an issue in foot mechanics. This can be caused by the person’s specific gait or the manner in which they walk, or by shoes that do not comfortably fit the deformity. Hammertoes can be formed after wearing shoes that are too narrow or short for the foot or have excessively high heels. Shoes that are not properly sized will force the toes into a bent position for long periods of time. This can cause the muscles to shorten and toes to bend into the deformity of a hammertoe.
Hammertoe can also be caused by complications from rheumatoid arthritis, osteoarthritis, trauma to the foot, heredity, or a cerebral vascular accident. Pain and difficult mobility of the toes, deformities, calluses, and corns are all symptoms of a hammertoe.
Someone who suspects they have the symptoms of a hammertoe should consult with a physician—particularly a podiatrist. Podiatrists diagnose and treat complications of the foot and ankle. If the podiatrist discovers that the affected toes are still flexible, treatment for the hammertoe may simply involve exercise, physical therapy, and better-fitting shoes. Treatment for hammertoes typically involves controlling foot mechanics, such as walking, through the use of customized orthotics.
For more serious cases in which the toes have become inflexible and rigid, surgery may be suggested. During the operation, the toe would receive an incision to relieve pressure on the tendons. A re-alignment of the tendons may then be performed by removing small pieces of bone to straighten the toe. In some cases, the insertion of pins is needed to keep the bones in the proper position as the toe heals. The patient is usually allowed to return home on the same day as the surgery.
If surgery is performed to repair a hammertoe, following the postoperative directions of your doctor is essential. Directions may include several stretches, picking up marbles with your toes, or attempting to crumple a towel placed flat against your feet. Wear shoes that have low heels and a wide amount of toe space to maintain comfort. Closed-toe shoes and high heels should be avoided. Shoes with laces allow the wearer to adjust how fitted he or she may want the shoes to be and also allow for greater comfort. To provide adequate space for your toes, select shoes that have a minimum of one-half inch of space between the tip of your longest toe and the inside of the shoe. This will also relieve pressure on your toes and prevent future hammertoes from forming.
Other preventative measures that can be taken include going shopping for new shoes in the middle of the day. Your feet are its smallest in the morning and swell as the day progresses. Trying on and purchasing new shoes midday will give you the most reliable size. Be sure to check that the shoes you purchase are both the same size. If possible, ask the store to stretch out the shoes at its painful points to allow for optimum comfort.
A podiatrist will be able to address a variety of rare foot conditions, particularly the ones that affect children. The most common are Kohler’s disease, Maffucci syndrome, and Freiberg’s disease. They can be properly diagnosed by having an X-ray taken, but in more serious cases an MRI may be needed. Kohler’s disease generally affects younger boys and bone deterioration may result from an interruption of blood supply. Children who have Kohler’s disease may find relief when the affected foot is rested, and a special boot is worn. Benign growths in the long bones of a child’s foot may lead to the development of bone lesions, and this is known as Maffucci syndrome. People who have this condition find mild relief when custom-made orthotics are worn. Freiberg’s disease targets the ball of the foot and can typically affect pre-teen and teenage girls. The metatarsal bone becomes deteriorated and flattened, and common symptoms include swelling and stiffness. A cast is often necessary to wear with this disease as it can help to reduce existing pain. Erythromelalgia is a rare foot condition, and its cause is unknown. Symptoms of this disease can include intense burning pain and the feet may appear red or feel warm. Relief may be found when the affected foot is immersed in ice water. It can also be beneficial to elevate the foot frequently. If your child complains of foot pain, it is strongly suggested that you consult with a podiatrist who can diagnose and treat rare foot conditions.
An ingrown toenail is a nail that has curved downward and grows into the skin. This typically occurs at the nail borders, or the sides of the nail. As a result, pain, redness, swelling, and warmth may occur in the toe. If a break in the skin forms due to the ingrown nail, bacteria may enter and cause an infection in the area; this is typically characterized by a foul odor and drainage.
Ingrown toenails have multiple reasons for developing. In many instances, the condition is a result of genetics and is inherited. The most common cause, however, is improper trimming; cutting the toenails too short forces the skin beside the nail to fold over. An ingrown toenail can also develop due to trauma, such as stubbing the toe, having an object fall on the toe, or participating in activities that involve repeated kicking or running. Wearing shoes that are too tight or too short can also cause ingrown toenails.
Treatment for an ingrown toenail varies between patients and the severity of the condition. Milder cases that don’t involve infection or other medical conditions can benefit from soaking the feet in room-temperature water and gently massaging the side of the nail. In most cases, however, it is best to see your podiatrist for thorough and proper treatment. After examining your toe, your podiatrist may prescribe oral antibiotics to clear the infection if one is present. Surgical removal of either a portion of the nail or the entire nail may also be considered. In some cases, complete removal or destruction of the nail root may be required. Most patients who undergo nail surgery experience minimal pain afterward and can return to normal activity the following day.
Ingrown toenails can be prevented with proper nail trimming and by avoiding improper-fitting shoes. When cutting the toenails, be sure that you are cutting in a straight line and avoid cutting them too short. Shoes should not be too short or tight in the toe box.
