The Importance of Biomechanics in Podiatry

Biomechanics and its related study deal with the forces that act against the body and affect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot, as well as the forces that impact them. Podiatrists who train in this specialty are able to effectively diagnose and treat conditions that affect people’s everyday movement.

Regardless of your lifestyle, age, or any other factors, many people experience foot problems throughout their lives. Twists and turns, improper balance, and added weight are just a few of the things that can add stress to the feet. These issues can also limit our bodies’ mobility that we often take for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area. This affects the way you move around on a daily basis.

Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area. This affects the way you move around on a daily basis.

The history of studying biomechanics dates back to ancient Egypt at around 3000 B.C., where evidence of professional foot care has been recorded. Throughout the centuries, advances in technology, science, and an understanding of the human body led to more accurate diagnosis of conditions such as corns for example. In 1974, biomechanics garnered a large audience when Merton Root founded Root Lab to make custom orthotics. He proposed that corrections of certain conditions could be implemented to gain strength and coordination in the area. Due to his research, we still use his basic principle of foot orthotics to this day.

As technology has improved, so have the therapeutic processes that allow us to correct deficiencies in our natural biomechanics. Computers can now provide accurate readings of the forces, movements, and patterns of the foot and lower leg. Critical treatment options can be provided to patients now who suffer from problems that cause their biomechanics to not function naturally. The best results are now possible thanks to 3D modeling and computing technologies that can take readings and also map out what treatment will do to the affected areas.

These advanced corrective methods were able to come to light thanks to an increase in both the technologies surrounding biomechanics and also the knowledge of how they work naturally. For example, shoe orthotics are able to treat walking inabilities by realigning the posture deviations in patients caused by hip or back problems. Understanding foot biomechanics can help improve movement and eliminate pain, stopping further stress to the foot. Speak with your podiatrist if you have any of these problems.

Arthritic Foot Care

During your lifetime, you will probably walk about 75,000 miles, which is quite a lot of stress to put on your feet. As you get older, the 26 bones and 30 joints in each of your feet will lose flexibility and elasticity. Your foot’s natural shock absorbers will wear down as well. Having arthritis added to this mix only makes matters worse. Your joints will become distorted and inflamed, which is why arthritic foot care needs to be something to think about every day.

When dealing with arthritis, having additional foot complications, such as bunions, hammertoes, or neuroma, can be a serious detriment. To avoid these, buy well-fitting shoes with a lower heel and good support. Arthritis causes you to lose your arch, so having shoes with good arch support is also highly recommended.

Aside from getting good arch support, the shoes need to fit comfortably and properly as well. A good place to start is by leaving a finger width between the back of the shoe and your foot to gauge proper size. It is also helpful to have a square or rounded toe box in the front to provide even more comfort. Another thing to look for is a rubber sole that can provide a cushion and absorb shock as you walk. This adds flexibility to the ball of your foot when you push off your heel to walk.

Exercise is another key aspect of arthritic foot care. Exercise not only strengthens and stretches your muscles and joints, but helps to prevent further injury and pain as well. Stretching the Achilles tendon, the tendon located in the back of your heel, will give you added mobility and reduce pain due to stress. Another thing you can do is massage your feet, kneading the ball of your foot as well as your toes from top to bottom.

Stretching the Achilles tendon is a simple exercise that you can do at home anytime. Lean against the wall with your palms flat against the surface while placing one foot forward, towards the wall, and one foot behind you. Bend your forward knee towards the wall while keeping your back knee locked straight, and make sure both your heels are completely touching the ground at all times. This will stretch your Achilles tendon and calf muscles as well. You will feel the stretch almost immediately. You can also stretch your toes in a couple ways. One involves taking a rubber band and wrapping it around both your big toes while your heels remain together. Then, pull them apart to stretch your big toe. You can also place a rubber band around all the toes of one of your feet. Then, try to separate each individual toe, stretching them all.

A final step you can take to help your arthritis is taking non-steroid, non-inflammatory drugs or topical medicines with capsaicin. Unfortunately, there is no complete way to remove all of your arthritic pain. However, following some of this advice can go a long way in staying as pain-free as possible.

Rare Foot Conditions

A podiatrist will be able to address a variety of rare foot conditions, particularly the ones that affect children. The most common are Kohler’s disease, Maffucci syndrome, and Freiberg’s disease. They can be properly diagnosed by having an X-ray taken, but in more serious cases an MRI may be needed. Kohler’s disease generally affects younger boys and bone deterioration may result from an interruption of blood supply. Children who have Kohler’s disease may find relief when the affected foot is rested, and a special boot is worn. Benign growths in the long bones of a child’s foot may lead to the development of bone lesions, and this is known as Maffucci syndrome. People who have this condition find mild relief when custom-made orthotics are worn. Freiberg’s disease targets the ball of the foot and can typically affect pre-teen and teenage girls. The metatarsal bone becomes deteriorated and flattened, and common symptoms include swelling and stiffness. A cast is often necessary to wear with this disease as it can help to reduce existing pain. Erythromelalgia is a rare foot condition, and its cause is unknown. Symptoms of this disease can include intense burning pain and the feet may appear red or feel warm. Relief may be found when the affected foot is immersed in ice water. It can also be beneficial to elevate the foot frequently. If your child complains of foot pain, it is strongly suggested that you consult with a podiatrist who can diagnose and treat rare foot conditions. 

Toe Pain

Toe pain can originate from corns, calluses, hammertoes, and bunions, as well as ingrown toenails, sprains, fractures, and dislocations. Corns develop as the toe rubs against the inside of a shoe which causes the skin to thicken as a form of protection. A corn is typically cone-shaped and has a small, hardened spot that points inward. When a corn is pressed into the skin, the toe becomes painful. Corns usually form on the top or side of the toe. A callus is also a thickened patch of skin that generally forms on the bottom of the foot. Calluses are the result of friction from the toe rubbing against the inside of a shoe. They may also occur by walking barefoot or having flat feet. A hammertoe is a bump on the knuckle of the second toe that is produced by wearing shoes that are too short for your feet. The bony protrusion rubs against the top of the shoe causing pain and irritation. A bunion is a malformation of the big toe. The base of the big toe pushes away from the smaller toes, forcing the top of the big toe to press toward the other toes. Bunions can be hereditary, or they can result from injury to the toe joint or from wearing high heels with a narrow toe box. The toe becomes inflamed, and a bump may develop at the end of the misplaced bone. Ingrown toenails typically affect the big toe and its surrounding skin. The nail will dig into the skin and become painful. Wearing tight or narrow shoes that compress the big toe causes the nail to grow into the fleshy part of the toe. Cutting toenails incorrectly can also add to the development of an ingrown toenail. A toe sprain originates from a torn or stretched ligament. Strapping the injured toe to the toe next to it for stabilization is common. A broken or fractured toe usually occurs from trauma like dropping a heavy object on it or bumping into something extremely hard and rigid. Osteoporosis, a thinning of the bones, can also bring about toe fractures. 

Any of the conditions mentioned can lead to pain and irritation. While some are more serious than others, seeking an examination and diagnosis from a podiatrist is a good idea. A podiatrist can treat each ailment and get you back on your feet again without pain.


 

Wound Care

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.

Sports Related Foot And Ankle Injuries

Foot and ankle injuries are common among people who participate in sports. Several factors contribute to this. They include failing to stretch or warm up properly, not wearing the proper type of shoe and not taping or providing other types of support for the ankle or foot. The most common foot and ankle injuries suffered by people involved in sports are plantar fasciitis, ankle sprains and Achilles tendon damage or ruptures. If not treated properly, they can lead to permanent disability.

Treating these injuries is relatively simple if they are identified and addressed early. Many athletes dismiss the initial aches and pains associated with injury as just soreness or tired muscles. Their first response is usually to try to work through it. This can lead to serious problems. Many minor injuries are made far more serious when athletes continue to put strain and pressure on them. That attitude can change a mild strain into a serious strain and a minor tear into a rupture. Athletes should have unusual aches and pains evaluated by a skilled medical professional.

Plantar fasciitis is a painful injury. It is inflammation of the plantar fascia, the thick band of tissue running from the heel to the base of the toes. If left untreated, it can lead to a degenerative disease called plantar fasciosis. There are several effective treatments for this ailment. Doctors often prescribe rest, massages, stretching, night splints, physical therapy, anti-inflammatory medication, corticosteroids or surgery, usually in that order. The most effective treatment for plantar fasciitis is orthotics, which offers foot support. Surgery is occasionally used as a last resort, but it comes with the risk of nerve damage and infection and often does not stop the pain.

The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel bone. Running, jumping and walking all impact this tendon. Two common injuries to the Achilles tendon are tendonitis and a rupture of the tendon. Tendonitis is inflammation in the tendon often caused by an increase in the amount of stress placed on it. Non-surgical treatments include rest, ice or anti-inflammatory medication.  A rupture (tear) of the Achilles tendon can be treated by placing the lower leg in a cast for several weeks or with surgery. Many physicians feel surgery is the better option because it lowers the risk of re-ruptures. Both methods require 4 to 6 months of rehabilitation.

Ankle sprains are the most common sports related foot and ankle injury. A sprain occurs when the ligament holding the ankle bones and joint stretches beyond its normal range. It can be treated non-surgically with a combination of rest, ice wrapped around the joint for 30 minutes immediately after injury, compression by a bandage and elevating the ankle above the heart for 48 hours. This combination is referred to as RICE. Severe ankle sprains in which the ligaments are torn may require reconstructive surgery followed by rehabilitation.

Elderly Foot Care

As you grow older, you will start to notice more problems with your feet due to wear and tear. This may also happen because the skin will start to become thin and lose elasticity. Some signs of aging feet are regular aches and pains, bunion development, and clawed toes.

Fortunately, there are ways you can improve comfort, relieve pain, and maintain mobility in your feet. One of the best ways to deal with aging feet is to exercise. If you keep active, your muscles will become toned which will then strengthen the arches in the foot and stimulate blood circulation.

It is important that you practice proper foot care to protect your aging feet. You should wash your feet in warm water on an everyday basis. Afterward, the feet need to be dried well and it is important to dry between the toes. Your toenails should be trimmed and kept under control; nails that are poorly cut may become ingrown. At the end of each day, performing an inspection of your feet will allow you to detect any ailments in their early stages.

As you grow older, it becomes more important that you wear comfortable shoes. Your shoes should be secure, and they should provide decent arch support. If you are looking to buy a new pair of shoes, it is best to look for a pair that are made from a breathable material. It is also helpful to have shoes that have a bit of extra room at the top of the shoe, especially if you suffer from swollen feet.

The most common foot problems that elderly people will encounter are bunions, calluses, corns, hammertoes, heel pain, and foot problems related to diabetes. Some other issues include arch pain, tarsal tunnel syndrome, Achilles tendonitis, and Morton’s neuroma

An annual foot examination is a great way for you to ensure that you do not have any serious health problems with your feet. You should talk to a podiatrist about the available treatment options for whichever foot issue you are dealing with.

What to Know About a Broken Toe

The forefoot is composed of five metatarsal bones and fourteen phalanges. Each toe has three phalanges except for the big toe which only has two. Our toes play an essential role to the walking process, which is why a broken toe could seriously disrupt one’s ability to move around. Toe fractures are common and can be very painful. Fortunately, these injuries rarely require surgery and usually heal with rest and a change in activity.

Broken toes typically result from a traumatic event such as falling, stubbing the toe, or dropping something on the toe. Traumatic toe fractures may be categorized as either minor or severe fractures. At times, one may hear a “pop” or “crack” sound when the bone breaks. Common symptoms of a traumatic toe fracture include pain, throbbing, bruising, swelling, and redness.

Another type of toe fractures is a stress fracture. These injuries usually appear in the form of small hairline breaks on the bone. Stress fractures develop after repetitive activity instead of a single injury. Stress fractures occur when the muscles in the bone become too weak to absorb impact. Consequently, the toe bone becomes vulnerable to any pressure and impact it endures. Symptoms for a stress fracture in the toe include swelling without bruising, tenderness to the touch, pain that goes away with rest, and pain after walking or running.

If you suspect that you have a broken toe, you should make an appointment with your podiatrist. He or she will likely diagnose you by performing a physical exam and an X-ray. Treatment for a broken toe may include the R.I.C.E. method, buddy taping, surgery, or antibiotics. The R.I.C.E. method (Rest, Ice, Compression, and Elevation) is a common treatment method for many injuries because it decreases pain. Buddy tapping involves wrapping the injured toe next to an adjacent toe to keep it supported and protected. These two methods have proven to be effective in the healing process for toe fractures. The estimated healing time for a broken toe is approximately four to six weeks. If the injury becomes infected or requires surgery, the estimated healing time may take eight weeks or more. 

How to Prevent Running Injuries

Overtraining and overusing the feet are the main causes of common running injuries. A number of these common injuries are caused by overrunning. Runner’s knee is a condition that is characterized by the back of the kneecap beginning to wear away and cause pain in the knee. This frequently occurs due to either a decrease in strength in the quadriceps muscles or ill-fitting shoes that are lacking in proper support for the inside of the forefoot. Strengthening exercises focusing on the quad muscle and sports orthotics are the usual treatments for those suffering from runner’s knee. Prevention of the condition lies in a focus on hip strengthening and quad-strengthening to keep the kneecap aligned. To help learn the best exercise to heal runner’s knee, one can also undergo physical therapy.

One common injury, called iliotibial band syndrome, is often caused by overtraining. This condition occurs when the iliotibial band gets irritated, creating pain and discomfort in the outside knee area. Plantar fasciitis, another common running injury, also occurs as a result of inflammation and irritation. Plantar fasciitis is an inflammation and irritation of the bone in the foot. A large amount of pain is often experienced due to plantar fasciitis. The condition can be caused by a high arch, improper footwear, tight muscles, or flat feet. It can best be avoided by stretching and wearing appropriate footwear that supports the foot.

Another common injury for runners is stress fractures. These injuries occur due to running style, overtraining, or a lack of calcium. Stress fractures most often occur in several locations in runners, including the inner bone of the leg, the thighbone, the bone at the base of the spine and the bones of the toes. Stress fractures are best prevented by wearing proper footwear and by running on flat and hard surfaces; this will absorb some of the shock created during running.

Aside from overtraining, other causes of common running injuries include ill-fitting footwear, a lack of flexibility and strength, and irregular biomechanics. The best way to avoid running injuries is to prevent them from even occurring. Both iliotibial band syndrome and stress fractures are preventable. The first step that should be taken to prevent running injuries is to only wear footwear that fits properly and that is appropriate for whatever activity you are doing. Running shoes are the only protective gear available to runners that can safeguard them from sustaining injuries. Choosing the right pair of shoes is therefore extremely important. While running shoes are an important factor, it is also important to consider other facets of your running routine such as training schedules, flexibility, and strengthening. These elements should be considered and altered according to your running needs to best maximize your run and minimize the possibility of injury. Careful stretching before and after a run should also be considered to help prevent running injuries. Stretching muscles enables greater flexibility and a lesser chance of sustaining injury.

Corns: What Are They, and How Do You Get Rid of Them

Corns are thickened areas on the skin’s surface, to the point of being irritating and sometimes painful. Commonly found on the feet, corns are circular or cone-shaped. They develop where there are areas of pressure or friction, such as on the little toe when it rubs up against shoes, or on the ball of your foot.

Corns are often confused with a callus, but there is a difference between them. Corns can be raised bumps that are painful to the touch. They consist of a rough, thick area of skin that may be dry or waxy. Corns tend to be surrounded by skin that is inflamed, and are usually much smaller than calluses.

Removing the dead skin that has built up is the key in treating corns. Salicylic acid medication is most common in accomplishing this. The acid works by dissolving keratin, which is the protein that makes up the majority of corns. You can purchase salicylic acid over-the-counter in products such as wart removers. It comes in a variety of forms such as medicated pads, drops, or creams. However, people who are diabetic should not use salicylic acid, but should instead consult their doctor immediately.

According to the product directions, applying the medication directly onto the corn will treat it. The top layer of the corn will begin to turn white after use. When that occurs, the layers of skin can then be peeled away, making the corn smaller. Shaving off corns with razors or other pedicure equipment is never a good idea. This can lead to infection. If your corn gets infected, and is not treated immediately, a visit to the doctor will be necessary.

Another way to treat corns and help prevent their return is by using orthotic inserts, fitted by a podiatrist. Inserts fit right into your shoes and adjusts the way your foot fits into your shoes. This fixes the way you walk. This will lower your chances of getting corns, and eliminate current corns by reducing rubbing from friction.

Surgery is rarely used to treat corns, but does occur on occasion. Surgery actually deals with the underlying issue that causes corns. During surgery, the bone is shaved and any abnormalities are corrected, thus reducing the amount of friction that occurs during walking.

To prevent corns, the first step is reducing friction. Always wear shoes that fit well and don’t rub your feet. Pads can be purchased if you notice rubbing developing. These pads can be purchased over-the-counter, and can be simply placed on the irritated area. Wearing cushioned insoles in your shoes can always reduce the friction, and making sure to wear well-fitting shoes. This will ensure that your foot is not being squeezed awkwardly, and prevent corns from forming in the first place.
