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.

Rheumatoid Arthritis in the Feet

Rheumatoid Arthritis is a chronic progressive disease that attacks several joints throughout the body. It is an autoimmune disease in which the body’s immune system mistakenly attacks the joints. As a result, the tissue inside the joints, called synovium, starts to thicken and causes pain around the joints. The synovium is responsible for creating a fluid that lubricates the joints to help them move. Approximately 1.5 million people in the United States have Rheumatoid Arthritis. Women are almost three times as likely to have RA compared to men, and it’s disease usually begins between the ages of 30 and 60. People who have a genetic history of RA are more likely to develop the disease.

Symptoms of RA may include the following sensations in the joints: pain, tenderness, swelling, redness, warmth, stiffness, and loss of range. Swollen joints are a very common symptom for those with the disease. At times, it may be minimal, but it may also be very apparent. Another typical symptom is joint stiffness. Doctors will often use the direction of morning stiffness to measure the severity of a patient’s joint inflammation. Other RA symptoms include limping, anemia, fever, and fatigue.

To diagnose RA, your podiatrist will typically request x-rays to see how much damage there is in the joints. Blood tests may also be performed to show if there are any signs of anemia, or antibodies such as the rheumatoid factor. If you have previously been diagnosed with RA, you should know the disease may spread to your feet and ankles.

There are many non-surgical options that can be used to treat this ailment. Some of these options include physical therapy, foot massages, orthotics, bracing, supportive shoes, and steroid injections. Physical therapy is useful because it will help stretch and strengthen the joints in both the foot and ankle to improve joint function. Massages can help improve blood circulation which will be good for the feet. Choosing proper footwear will allow you to walk with comfortability if you are a sufferer from RA. Lastly, bracing will help stabilize the foot joints, limit deformities and decrease pain.

In severe cases, surgery may be a treatment option that should be considered. For those who cannot walk without experiencing pain and those whose deformities can not be managed with braces, surgery should be considered. Your podiatrist will recommend surgery if he or she believes it will improve your foot biomechanics.

Bunions

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.

Heel Pain

Have you ever gotten up from a chair or out of bed in the morning, and upon taking that first step, feel like your heel has stepped on a tack? Many people experience a feeling of sharp pain which radiates into their arch from their heel and which does not allow them to put their heel on the floor. Sometimes they need to sit back down, stand only on their toes and use the wall for balance. If you can take a few steps, it seems to go away and lessen, allowing you to then resume your activity. Later, throughout your day and after a period of rest, it can happen again. If this sounds familiar you may be suffering from your first attack of heel pain.

Heel pain is a debilitating condition that affects day to day activities. Running and walking both causes stress on the heel because the heel is the part of the foot that hits the ground first. This means that the heel is taking on your entire weight. Diagnosis and treatments for heel pain can be easily found through your podiatrist.

Plantar Fasciitis

One of the main causes of heel pain is a condition known as plantar fasciitis. The plantar fascia is a band of tissue that extends along the bottom of the foot, from the toe to the bottom of the heel. A rip or tear in this ligament can cause inflammation of these tissues, resulting in heel pain. People who do not wear proper fitting shoes are often at risk of developing problems such as plantar fasciitis. Unnecessary stress from ill-fitting shoes, weight change, excessive running, and wearing non-supportive shoes on hard surfaces are all causes of plantar fasciitis.

Achilles Tendonitis

Achilles tendonitis is another cause of heel pain. Similar to plantar fasciitis, inflammation of the Achilles tendon will cause heel pain due to stress fractures and muscle tearing. A lack of flexibility of the ankle and heel is an indicator of Achilles tendonitis. If left untreated, this condition can lead to plantar fasciitis and cause even more pain on your heel.

Heel Spur

A third cause of heel pain is a heel spur. A heel spur occurs when the tissues of the plantar fascia undergo a great deal of stress, leading to a separation of the ligament from the heel bone entirely. This results in a pointed fragment of bone on the ball of the foot, known as a heel spur.

Diabetic Foot Care

Diabetes affects millions of people every year. Blood vessels located all over the body are damaged due to diabetes—even the blood vessels of the feet. Neuropathy, or nerve damage, can result from slower blood flow in the legs and feet. In diabetic patients, neuropathy is very important to monitor, as diabetics are at risk for developing ulcers.

Always washing and thoroughly drying the feet are pertinent parts of diabetic foot care. There should be a focus on cleaning between the toes. Even if no pain is felt, the entire foot should be examined for redness and sores. Neuropathy can often mask the pain of sores and ulcers and can cause these conditions to be overlooked. Use a mirror to examine the underside of your feet if needed. It is recommended that diabetics wear well-fitting socks.

Patients with diabetes should have their specialist monitor their blood levels because blood sugar levels play a huge role in diabetic care. Monitoring these levels on a regular basis is highly advised. It is very important to keep your blood sugar levels in the normal range, which can be determined by your provider. There are medications that may be prescribed to help with any neuropathy experienced by the diabetic patient. It is also advisable to visit a podiatrist if one is experiencing any conditions involving the feet, such as ingrown toenails, which in more severe cases can cause infection.

Diabetic feet must be inspected daily. Diabetic foot care at home is possible if a patient is provided with instructions from their podiatrist. Patients can relieve dry heels with creams or ointments. Suspected wounds should warrant an immediate call to the podiatrist. Gangrene is a serious problem for diabetics and can lead to sepsis and amputation in its worst cases. Early treatment and daily inspection of diabetic feet are keys to staying healthy.
