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.
Diabetes can cause two problems that can potentially affect the feet: Diabetic neuropathy and Peripheral Vascular Disease. Diabetic neuropathy occurs when nerves in your legs and feet become damaged, which prevents you from feeling heat, cold, or pain. The problem with diabetic neuropathy is that a cut or sore on the foot may go unnoticed and the cut may eventually become infected. This condition is also a main cause of foot ulcers. Additionally, Peripheral vascular disease also affects blood flow in the body. Poor blood flow will cause sores and cuts to take longer to heal. Infections that don’t heal do to poor blood flow can potentially cause ulcers or gangrene.
There are certain foot problems that are more commonly found in people with diabetes such as Athlete’s foot, calluses, corns, blisters, bunions, foot ulcers, ingrown toenails, and plantar warts. These conditions can lead to infection and serious complications such as amputation. Fortunately, proper foot care can help prevent these foot problems before they progress into more serious complications.
Each day you should wash your feet in warm water with a mild soap. When you finish washing your feet, dry them carefully especially between your toes. You should also perform daily foot inspections to ensure you don’t have any redness, blisters, or calluses. Furthermore, if you are diabetic, you should always wear closed-toed shoes or slippers to protect your feet. Practicing these tips will help ensure that your feet are kept healthy and away from infection.
If you have diabetes, contact your podiatrist if you have any of the following symptoms on your feet: changes in skin color, corns or calluses, open sores that are slow to heal, unusual and persistent odor, or changes in skin temperature. Your podiatrist will do a thorough examination of your feet to help treat these problematic conditions.
Our bones are important aspects of our body and they are constantly changing. The heavier the workload for a bone, the more likely it is that calcium will be placed in it. When a bone isn’t used often, there won’t be much calcium within it. When stress from repetitive loads prevent the bone from being able to repair itself, cracks will start to form. Stress fractures are defined as cracks in a bone that result from repetitive force, such as overuse.
The most common cause of stress fractures is a sudden increase in intensity and duration of physical activity. For example, if you begin to run long distances without working your way into doing so, you will be more likely to develop a stress fracture.
Common symptoms of stress fractures are pain and swelling near the weight bearing area on the injured bone. When initial x-rays are performed, it is possible that the fracture will not show up. However, once the stress on the area continues, the damage will increase, and the fracture will be severe enough to show up on an x-ray. Certain parts of the foot are more likely to develop stress fractures than others. Areas that typically have these fractures are: the metatarsals, the navicular bone, the calcaneus, tibia, and fibula.
Since women are at an increased risk of developing osteoporosis, they are twice as likely as men to sustain a stress fracture. Additionally, old age causes a decrease in bone mineral density which is why elderly people are also likely to develop these fractures.
It is important for you to be professionally diagnosed by a podiatrist if you suspect you have a stress fracture, because there are other injuries that can easily be mistaken for a fracture. Sprains, strains, shin splints, plantar fasciitis, and Morton’s neuroma can all easily be mistaken for stress fractures in the foot. Your podiatrist will likely ask you a series of questions to determine what type of pain you are experiencing. These questions will help your doctor identify whether you have a stress fracture.
The best method of treatment for a stress fracture is rest. Additionally, a walking boot, cast, or crutches, will help rest the area that is injured. The typical healing time for stress fractures is 4-12 weeks, however this depends on which bone is involved.
Foot and ankle pain can be a nuisance in a person’s life, especially if it happens frequently. The best way to prevent this type of pain, is to exercise often. Regular exercise of the foot includes stretching and strength exercises. Stretching exercises can help prevent injuries such as a sprained ankle, while strength exercises can prevent ailments such as plantar fasciitis.
Stretching exercises can help improve flexibility and the foot and ankle’s range of motion. These exercises can certainly help with those who participate in high-energy activities such as sports. Many athletes routinely perform foot and ankle exercises to prevent injuries like sprained ankles, which are common injuries where the tendons in the ankle are over stretched. Strength exercises help develop foot muscles for better support and protection.
Most exercises are simple and can be done at home, either standing or sitting. One chair exercise is called “limber up”. In this exercise, a person would start by sitting down with their feet flat on the floor. Then lift one leg up so the feet are not touching the floor, then rotate your foot clockwise 15-20 times, and 15-20 times counterclockwise. Repeat the same process with the opposite leg. Another sitting exercise helps stretch the back of your heel and requires an exercise band. It begins by looping the band around a heavy piece of furniture, or something stable that will not be moved when the band is tugged or pulled. Then sit directly in front of it, and slide one foot into the loop, so that the band curves around the forefoot. Start by pulling the forefoot back and holding it for 5-10 seconds. Doing this 10-15 times on each foot, will stretch the back of your heel, increasing your flexibility.
Foot exercises that require standing are also just as easy and simple. Referred as the “Achilles Stretch”, this exercise stretches the Achilles tendon, making it more flexible, helping prevent foot, ankle, and leg pain. It begins by first standing and facing the wall, with the arms outstretched and the palms on the wall. Then place one foot behind another keeping the back leg straight, and the forward leg bending at the knee. Make sure both heels are flat on the floor and adjust your stance accordingly. With your hips, lean forward to feel the stretch, you can also adjust the distance from your feet to feel the stretch in various parts of the calf. Make sure to hold the stretch for about 30 seconds and repeat the same process 3 times with each leg. An even easier foot exercise is simply walking on sand. Walking barefoot on sand both strengthens and stretches your feet.
Doing these exercises regularly can help prevent many foot and ankle problems. Other foot exercises can even relieve pain. For example, those affected with plantar fasciitis can simply sit down on a chair, and then place a tennis ball below their affected foot. By rolling the ball under the foot, and increasing or decreasing pressure, pain will be relieved. With any exercise, it is always important to do a small warmup such as walking a few laps around the house to get the blood flowing. If after doing an exercise to relieve pain such as the tennis ball exercise, or are unsure that your execution is correct, be sure to contact a podiatrist for further instruction.
Gout, typically found in diabetic patients, is an unusually painful form of arthritis caused by elevated levels of uric acid in the bloodstream. The condition typically strikes the big joint on the big toe. It has also been known to strike the knees, elbows, fingers, ankles and wrists—generally anywhere that has a functioning, moving joint.
The high level of uric acid in a person’s bloodstream creates the condition known as hyperuricema—the main cause of gout. Genetic predisposition occurs in nine out of ten sufferers. The children of parents who suffer gout will have a two in ten chance of developing the condition as well.
This form of arthritis, being particularly painful, is the leftover uric acid crystallizing in the blood stream. The crystallized uric acid then travels to the space between joints where they rub, causing friction when the patient moves. Symptoms include: pain, redness, swelling, and inflammation. Additional side effects may include fatigue and fever, although reports of these effects are very rare. Some patients have reported that pain may intensify when the temperature drops, such as when you sleep.
Most cases of gout are easily diagnosed by a podiatrist’s assessment of the various symptoms. Defined tests can also be performed. A blood test to detect elevated levels of uric acid is often used as well as an x-ray to diagnose visible and chronic gout.
Treatment for gout simply means eliminating symptoms. Non-steroid anti-inflammatory drugs or NSAIDs (Colchicine and other corticosteroid drugs, etc.) will quell the redness, the swelling, and the inflammation. However, managing your diet, lifestyle changes, and using preventative drugs are all helpful toward fully combating the most severe cases.
Those that lead an inactive lifestyle are at a higher risk for gout. Any amount of exercise decreases the probability of repeat encounters with the condition. Reducing your consumption of red meat, sea food, and fructose-sweetened drinks also reduces the likelihood of chronic gout as well.
Ingesting Vitamin C, coffee, and particular dairy products can help with maintaining a healthy lifestyle. There are new drugs out on the market that inhibit the body’s production of uric acid-producing enzymes. However, reducing or eliminating your overall levels of uric acid is the best remedy to ensuring you lead a gout-free life.
When conservative, noninvasive methods prove ineffective, surgery may be selected as the next course of action for the treatment of your foot or ankle condition. A wide number of foot and ankle surgical procedures exist, and it is up to your podiatrist to determine which intervention will be most appropriate and helpful for your case. Some surgical procedures include bunion surgery, fusion, hammertoe surgery, heel spur surgery, metatarsal surgery, nail surgery, neuroma surgery, reconstructive surgery, skin surgery, and tendon surgery. Typically, surgery is turned to as a definitive way to alleviate excessive pain or discomfort and to return your foot to full mobility.
Regardless of the location on the body, all surgical procedures require preoperative testing and examination to ensure the surgery’s success and preferred outcome. A review of your medical history and medical conditions will take place, as will an evaluation of any current diseases, illnesses, allergies, and medications. Tests such as blood studies, urinalyses, EKG, X-rays, and blood flow studies may be ordered. Because the procedure involves the foot and/or ankle, the structures of your feet while walking may also be observed by your podiatrist.
Care post-surgery will depend on the type of surgical procedure performed. Typically, all postoperative care involves rest, ice, compression, and elevation. To improve and ensure a safe recovery, your foot and ankle surgeon may also employ the use of bandages, splints, surgical shoes, casts, crutches, or canes. He will also determine if and when you can bear weight. A timely and thorough recovery is a priority for both you and your podiatrist, and carefully following postoperative instructions can help achieve this.
A bunion is a bump that forms at the base of the big toe. Bunions form when the big toe pushes against the next toe, which forces the big toe joint to get bigger and stick out. As a result, the skin over the bunion may start to appear red and it may feel sore.
There are risk factors that can increase your chances of developing bunions. People who wear high heels or ill-fitting shoes are more likely to develop them, in addition to those who have a genetic history of bunions or have rheumatoid arthritis.
The most obvious way to tell if you have a bunion is to look for the big toe pushing up against the toe next to it. Bunions produce a large protrusion at the base of the big toe and may or may not cause pain. Other symptoms are redness, swelling, and restricted movement of the big toe if you have arthritis.
Nonsurgical methods are frequently used to treat bunions that aren’t severe. Some methods of nonsurgical treatment are orthotics, icing and resting the foot, taping the foot, and pain medication. Surgery is usually only required in extreme cases. However, if surgery is needed, some procedures may involve removing the swollen tissue from around the big toe joint, straightening the big toe by removing part of the bone, or joining the bones of your affected joint permanently.
Your podiatrist will diagnose your bunion by doing a thorough examination of your foot. He or she may also conduct an x-ray to determine the cause of the bunion and its severity.
The Achilles tendon is the largest tendon in the body; it is a tough band of fibrous tissue that stretches from the bones of the heel to the calf muscles. This tendon is what allows us to stand on our toes while running, walking, or jumping, it is common for this tendon to become injured. In severe cases, the Achilles tendon may become partially torn or completely ruptured. However, this tendon is susceptible to injury because of its limited blood supply and the high level of tension it endures.
The people who are more likely to suffer from Achilles tendon injuries are athletes who partake in activities that require them to speed up, slow down, or pivot. Consequently, athletes who engage in running, gymnastics, dance, football, baseball, basketball, or tennis are more likely to suffer from Achilles tendon injuries. Additionally, there are other factors that may make you more prone to this injury. People who wear high heels, have flat feet, tight leg muscles or tendons, or take medicines called glucocorticoids are more likely to have Achilles tendon injuries.
A common symptom of an Achilles tendon injury is pain above the heel that is felt when you stand on your toes. However, if the tendon is ruptured, the pain will be severe, and the area may become swollen and stiff. Other symptoms may be reduced strength in the lower ankle or leg area, and reduced range of motion in the ankle. When the Achilles tendon tears, there is usually a popping sound that occurs along with it. People who have acute tears or ruptures may find walking and standing to be difficult.
If you suspect you have injured your Achilles tendon, you should see your podiatrist to have a physical examination. Your podiatrist will likely conduct a series of tests to diagnose your injury including a “calf-squeeze” test. Calf squeeze tests are performed by first squeezing the calf muscle on the healthy leg. This will pull on the tendon and consequently cause the foot to move. Afterward, the same test will be performed on the injured leg. If the tendon is torn, the foot won’t move because the calf muscle won’t be connected to the foot.
A congenital foot problem is a problem affecting the feet, toes, and/or ankle that a child is born with. Several issues with a child’s feet can occur congenitally. Such problems include clubfoot, vertical talus, tarsal coalition, polydactyly, macrodactyly, and cleft foot. Some of these problems have a genetic basis, with someone in their family history having a gene causing the condition, and some are simply an anomaly.
The following are specifics about a few of these conditions:
- Clubfoot, also called congenital talipes equinovarus or talipes equinovarus, is When the tendons of the foot shorten, the bones are of an unusual shape, and the Achilles tendon is tight, causing an inward and downward pointing of the foot. The soles of the feet might also face each other. In most cases of clubfoot, both feet are affected. If not treated, the affected child will walk on the sides of their feet or ankles.
- Polydactyly is a condition where the child has more than five fingers or toes on either or both feet. Presentation usually consists of a nubbin or small lump of tissue without a bone, a toe that is partially formed but has no joints, or an extra toe.
- Vertical talus is where the talus bone forms in the wrong position, other bones in the foot do not line up properly, the front of the foot points up, and the bottom of the foot is stiff, has no arch, and usually curves out. This can occur in one or both feet and if left untreated, can lead to serious disability or discomfort as the child grows.
- Tarsal coalition is when there is an abnormal connection of two or more bones in the foot leading to severe, rigid flatfoot. The tarsal bones, located toward the back of the foot and in the heel, are the ones affected. This condition is often present at birth, but signs of the disorder usually come on in early adolescence.
- Cleft foot is a rare condition where the foot has missing toes, a V-shaped cleft, and other anatomical differences. Surgery can often help improve the foot’s function since the heel remains normal and is what is most needed for walking. The main issues with this affliction are whether the affected foot can fit into a shoe and the shape and appearance of the foot.
- Macrodactyly is when the toes are abnormally large due to overgrowth of the underlying bone or soft tissue. Having this condition makes it harder for the child to use the affected foot for certain activities.
Pain experienced in the ankle can be caused by a multitude of conditions. While the most common cause is an ankle sprain, other possible problems can include arthritis, gout, ankle instability, an ankle fracture, nerve compression, or tendinitis. In more serious cases, ankle pain can be a sign of improper alignment of the foot or an infection.
Ankle pain can often be accompanied by symptoms such as redness, swelling, stiffness, and warmth in the affected area. Pain can be described differently depending on the condition: short, stabbing pain and a dull ache are some examples. If such symptoms are persistent and do not improve after time, be sure to schedule an appointment with your local podiatrist.
Depending on the condition causing your ankle pain, different treatments may be prescribed by your podiatrist. For ankle sprains, the first step in treatment involves rest, ice, elevation, and compression. Be sure to avoid placing pressure on the ankle, use an ice pack several times a day, and use a compression bandage and elevation to reduce swelling. Other, more serious conditions may require the assistance of certain drugs and medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, or even cortisone injections.
Depending on the severity of your ankle pain and the condition behind it, recovery from ankle pain may take some time.
Consult with your foot and ankle doctor to best determine the cause of your ankle pain and the appropriate treatment.

Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
An ankle sprain occurs when one or more ankle ligament gets overly stretched. Ligaments are strong bands of tissue that bind and support the bones and other structures that make up the ankle. In more severe ankle sprains, the ligament(s) tear—either partially or completely—and there may be an audible popping noise at the moment of injury.
Ankle sprains are quite common and can occur when the ankle rolls outwardly (eversion) or inwardly (inversion), causing the ligament(s) to stretch beyond normal limits, or even tear. Falls, twists, or blows to the ankle during sports or other activities can cause this injury, as well as wearing improper footwear, running on uneven surfaces, or having weak ankles.
Depending on the injury’s severity, an ankle sprain will be classified as Grade I, Grade II, or Grade III. Grade I sprains involve ligament(s) being overly stretched but not torn, with symptoms of mild pain, swelling, and ankle instability. There may also be some difficulty bearing weight. A Grade II sprain usually involves a partial tear of the ligament which brings more intensity in these symptoms, along with possible bruising. With a Grade III sprain, the ligament is completely torn, the symptoms are severe, and it may not be possible to put weight on the affected foot at all.
To diagnose and grade an ankle sprain, a podiatrist will perform a physical examination, checking for tenderness and range of motion in the ankle. For more severe sprains, X-rays or other imaging studies may be necessary.
It is vitally important to have an ankle sprain treated properly as improper healing often leads to future ankle sprains and possibly even chronic ankle stability. Treatment for an ankle sprain will vary, depending on its severity, and may include the RICE method (Rest/Ice/Compression/Elevation), physical therapy, bracing, medications, and possibly even surgery to repair a torn ligament. Rehabilitation is very important for the sprain to heal properly and to restore functionality.
Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet. Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.
Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.
Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.
Choosing the right running shoes for you is an important part of running. A good pair of running shoes will make the running experience more enjoyable for you and prevent potential injury.
Poorly-fitted shoes can increase the risk of injury in runners substantially. Common injuries from running with poor quality shoes include shin splints, sprained ankles, Achilles tendinitis, stress fractures, plantar fasciitis and more. This is due to the fact that bad shoes do not provide proper foot support, can increase pronation (how much the foot rolls when hitting the ground), have little to no cushioning, do not allow the feet to breath, and do not provide enough flex and rigidity in the right parts.
When looking for running shoes, first, determine where you will be running. If you are a trail runner, then pick trail shoes. If you run on concrete and asphalt, then regular running shoes are the best choice. When trying on shoes, its best to go at the end of the day as feet grow during the day and shrink after a night of sleep. Shoes should be more rigid towards the back of the foot while being more flexible up where the toes are. The toe box should provide enough room for the toes to move freely. The overall fit should be snug, not too tight but not too loose. A good pair of running shoes should also provide enough arch support for your foot type. If you experience overpronation or under-pronation while running, try to find a pair of shoes that will help correct this with different sole patterns. Finally, try to find a pair of shoes that allow the feet to breathe like nylon mesh or synthetic leather.
Don’t forget about the socks either. Socks that hold too much moisture can lead to athlete’s foot. Socks should be breathable so that your feet can air out and breathe. Synthetic socks wick away moisture like sweat. If you tend to run a lot, having a second pair of shoes that you can wear while you let the first pair air out is smart. Just don’t forget to replace your shoes after about every 300 to 500 miles.
Before you start running, it is advised to see a podiatrist to see if running is right for you. They can also offer good advice on how to run and what to look for in a pair of running shoes. If you have flat feet or poorly supported ones, they can also offer custom-made orthotics that will help give your feet the support they need.
