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.

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.

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. 

A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.

Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.

A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.

Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.

For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.

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.
