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.

Our feet are arguably the most important parts of our bodies because they are responsible for getting us from place to place. However, we often don’t think about our feet until they begin to hurt. If you have pain in your feet, you need to first determine where on the foot you are experiencing it to get to the root of the problem. The most common areas to feel pain on the foot are the heel and the ankle.
Heel pain is most commonly attributed to a condition called plantar fasciitis. Plantar fasciitis occurs when the plantar fascia, which is the band of tough tissue connecting the heel bone to the toes becomes inflamed. Plantar fasciitis pain is usually worse in the morning, and it tends to go away throughout the day. If you have plantar fasciitis, you should rest your foot and do heel and foot muscles stretches. Wearing shoes with proper arch support and a cushioned sole has also been proven to be beneficial.
Some common symptoms of foot pain are redness, swelling, and stiffness. Foot pain can be dull or sharp depending on its underlying cause. Toe pain can also occur, and it is usually caused by gout, bunions, hammertoes, ingrown toenails, sprains, fractures, and corns.
If you have severe pain in your feet, you should immediately seek assistance from your podiatrist for treatment. Depending on the cause of your pain, your podiatrist may give you a variety of treatment options.

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.

Tendons are fibrous tissues that connect muscles with bone. The Achilles tendon is the largest tendon in the body. It connects the calf muscles at the back of the leg with the heel, and facilitates movements such as jumping, running, and walking.
Because the Achilles tendon is engaged so frequently and bears a great deal of pressure and stress throughout the day, it can become injured. Achilles tendon injuries cause the tissue to become irritated, inflamed, and swollen. Pain can come on gradually or be immediate, and will vary from mild to severe depending upon the injury. Where the pain occurs will vary as well, from just above the heel up through the back of the leg. There may also be stiffness in the tendon.
Achilles tendon injuries can often be caused by repetitive stress. They may also occur while running, playing tennis, gymnastics, football, basketball, dancing, soccer, baseball or other sports that require speeding up, slowing down, or pivoting quickly. Wearing high heels, falling from an elevation, stepping in a hole, having flat feet, bone spurs, tight leg muscles or tendons, wearing improper athletic shoes, exercising on uneven surfaces, or starting a new type of exercise can also cause Achilles tendon injuries.
The two most common Achilles tendon injuries are tendonitis and ruptures. Tendonitis causes painful inflammation and can occur in different parts of the tendon. Non-insertional Achilles tendonitis occurs when the fibers in middle of the tendon begin to break down, thicken, and swell. This condition typically affects younger, more active adults. Insertional Achilles tendonitis occurs where the tendon inserts into the heel bone. It is common for bone spurs to form with this type of injury. This condition can affect people of any age and level of activity.
Achilles tendon ruptures are a tear in the tendon. These breaks may be partial or complete. There may be an audible popping noise at the moment of injury and the pain will be sudden and severe.
An Achilles tendon injury can be diagnosed by your podiatrist after they examine you, check your range of motion, and possibly perform a calf squeeze test or review an X-ray or MRI. Depending on the type and severity of your injury, your podiatrist may treat your condition with rest/ice/compression/elevation (RICE), nonsteroidal anti-inflammatory medications, heel lifts, and stretching and strengthening exercises. If you have torn your Achilles tendon, treatment may include physical therapy, ultrasound, shockwave therapy, or possibly even surgery.

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.

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.

Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is the thick band of tissue that connects the heel bone to the toes. When this band of connective tissue becomes inflamed, plantar fasciitis occurs. Fortunately, this condition is treatable.
There are several factors that may put you at a greater risk for developing plantar fasciitis. One of the biggest factors is age; plantar fasciitis is common in those between the ages of 40 to 60. People who have jobs that require them to be on their feet are also likely to develop plantar fasciitis. This includes factory workers, teachers, and others who spend a large portion of their day walking around on hard surfaces. Another risk factor is obesity because excess weight can result in extra stress being placed on the plantar fascia.
People with plantar fasciitis often experience a stabbing pain in the heel area. This pain is usually at its worst in the morning, but can also be triggered by periods of standing or sitting. Plantar fasciitis may make it hard to run and walk. It may also make the foot feel stiff and sensitive, which consequently makes walking barefoot difficult.
Treatment for plantar fasciitis depends on the severity of the specific case of the condition. Ice massage applications may be used to reduce pain and inflammation. Physical therapy is often used to treat plantar fasciitis, and this may include stretching exercises. Another treatment option is anti-inflammatory medication, such as ibuprofen.
If you suspect that you have plantar fasciitis, meet with your podiatrist immediately. If left untreated, symptoms may lead to tearing and overstretching of the plantar fascia. The solution is early detection and treatment. Be sure to speak with your podiatrist if you are experiencing heel pain.

Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.
Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.
Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.
Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.
It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.

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.

Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.
There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.
Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.
The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment. However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.
