Limb Salvage
Limb salvage is a procedure that involves saving a lower extremity from amputation. In podiatry, limb amputation often occurs as a result of diabetes, peripheral vascular disease, neuropathy, cancer, and severe crush injury. 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 the bone is removed, it is then replaced with prostheses, 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.
Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Treating Toenail Fungus
Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening. The fungal infection itself occurs beneath the surface of the nail. Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail. If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk.
The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms. Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails.
Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes. Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential. Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.
Fungal nail treatment may vary between patients and the severity of the condition. Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections. Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications. Debridement, or the removal of diseased nail matter and debris, may also be performed. In more severe cases, surgical treatment may be needed. In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed. In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.
Walking Shoes vs. Running Shoes
Although walking shoes and running shoes look similar, they have characteristics that make them different from each other. Runners should avoid running in walking shoes and vice versa. It is very important that you wear the proper footwear for the activity you are going to partake in, for you to avoid injury.
If you are looking to buy a new pair of running shoes, there are certain things you should look out for. One of the main components that makes up a good running shoe is flexibility. You should be able to bend and flex the forefoot of the shoe that you are purchasing. If you can bend the entire shoe in half with ease, this is a sign that the shoe does not have enough structure for your feet. Another feature you should look for is a low heel. Certain running shoes have a low heel to support runners who land on the ball of their feet. Lastly, you should look for the fit of the running shoe. You should visit the best running shoe store in your area to have your feet properly sized for the shoes in the store. Usually, the staff will be able to help recommend the best type of running shoe for your needs.
When you are walking, the body’s weight is evenly distributed on the foot. This influences the design of shoes made for walking. If you are looking to buy a pair of walking shoes, there are different features you should look for to determine which pair of shoes is best for you. Walking shoes should be flexible through the ball of the foot to allow for a greater range of motion through the roll of the forefoot. These shoes also should have greater arch support for the foot. If you plan on walking long distances or on hard surfaces, it is best that you wear shoes that have cushioning.
When trying on a new pair of shoes, the heel should fit snugly without slip. You should shop for shoes after a long walk, since your feet tend to swell throughout the day. Many people have one foot that is a different size than the other, so it is best that you have both feet measured when looking for your true size. You should also beware that sizes vary depending on the shoe brand. A certain size in one brand may be a different size in a different brand. Lastly, you should always walk around in shoes that you plan on buying. This will help you determine whether the shoes are comfortable and if they fit well on your feet.
Always look for good shoe construction when shopping for new sneakers. The upper part of the shoe should allow for adjustment through laces or straps. If you need help with shoe sizing or if you need custom orthotics for your feet, you should make an appointment with your podiatrist for assistance. He or she will be more than happy to help you with your shoe sizing needs.
