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.
According to the American Diabetes Association (ADA), diabetes is a condition that affects approximately 23.6 million Americans. Around 750,000 new cases are diagnosed each year, and the disease’s most common form, Type 2 diabetes, makes up for 90 to 95 percent of these cases. Type 2 diabetes is especially prevalent among older Americans, those who are obese, and those who lead sedentary lifestyles.
Complications of the disease may lead to several foot and ankle-related conditions. The loss of nerve sensation, or neuropathy, can cause diabetics to lose feeling at the bottom of the feet and therefore leave them unaware of pain, pressure, and heat. Decreased circulation is another complication of diabetes that can slow down the healing of wounds and injuries; this can lead to the development of foot ulcers.
To prevent foot ulcers from forming, diabetics should examine their feet every day for small cuts and wear shoes that curtail pressure. Constant monitoring for the risk factors associated with ulcer formation can allow for early detection and therefore lessen the possibility of ulcers or, even worse, amputation. The removal of calluses and ingrown toenails should be left to the podiatrist to avoid improper removal and possible infection.
Diabetic patients may also experience foot deformities due to complications in their feet, such as limited joint mobility, muscle atrophy, and decreased fat padding. These complications can increase pressure in certain areas of the foot, which in turn can cause certain deformities, such as hammertoe, to form. Another deformity, Charcot foot, develops due to the collapsing of microfractures in the bones of the feet. The resulting deformity is a foot that is flattened and wider in appearance.
To help minimize pressure and prevent the development of these diabetes-related foot and ankle conditions, your podiatrist may consider using orthotics or special shoes. Charcot foot may be treated using walkers, custom orthotic insoles, or non-weight-bearing or rigid weight-bearing casts or braces. In more serious cases, surgery may be considered to treat more developed deformities. Ulcers can be further cared for with the help of proper diet, medication to control glucose, intensive wound care, and infection treatment.
There are many reasons why patients experience swelling of the feet. It is rather common and may be a side effect of pregnancy or from sitting and standing for most of the day. Gravity could also play a role in the development of swollen feet. It is known that the weight of blood volume in our bodies is exerted on the veins in the legs and feet. The veins may not work as efficiently during the aging process, and this could make the blood flow backward causing swollen feet. Relief may be found when obese patients lose weight, and it may help to engage in compression therapy by wearing compression socks, stockings, or athletic sleeves. This method can release pressure on the feet and ankles which may help to reduce existing swelling. There are patients who have controlled their swollen feet by implementing healthy lifestyle changes. These can consist of reducing salt intake, incorporating a gentle exercise regime into the daily routine, and drinking plenty of fresh water. Swollen feet may be a temporary condition that affects people who travel via airplane or automobile, so it is beneficial to walk as frequently as possible even though it can be difficult. Swelling of the feet can also be indicative of other health issues so it is important to pay attention to any type of chest pain, mental confusion, dizziness, or fever. If you consistently have swollen feet, it is strongly suggested that you consult with a podiatrist who can help determine the cause and how to effectively treat it.
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.
