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.

Though cuboid syndrome predominately affects athletes, non-athletes can suffer from it too. Cuboid syndrome is also called cuboid subluxation or cuboid fault syndrome, and occurs when a joint or ligament near the cuboid bone of the foot becomes damaged, or when the bone itself is dislodged from its natural position. Pain may be persistent, or come and go, and it is usually marked by the outside of the foot. Cuboid syndrome, unless severe, can be difficult to diagnose. A doctor will likely ask questions about how long the pain has been present, and will apply pressure on the cuboid bone to determine the origin of pain.

There are a number of causes that can lead to the syndrome. Due to athletic activities, repeated stress placed on the foot can cause cuboid subluxation. Ballet dancers, runners, and other athletes often develop this condition. Basketball or tennis players may also develop this condition, as they place stress on their feet while moving side to side. Cuboid syndrome can often develop over time; however it can come out of a sudden injury as well. Over pronation, or other problems with feet, can exacerbate the condition if not corrected.

Among podiatrists, there is some disagreement about the treatment, as well as the definition of cuboid syndrome. Some see the injury as an injury to the ligaments located nearby the cuboid bone, while others believe it refers to the dislocation of the calcaneal-cuboid joint only. Treatment opinions differ as well. Although it can be treated by manipulation in order to reposition the bone, this must be done with extreme care in order to avoid injury. Some doctors, however, prefer treatment through the use of orthotic pads, designed to keep the bone in its place. Effectiveness of these treatments may vary, according to the severity of the injury.

When you experience side foot pain, it is important that you seek medical assistance. If a subluxed cuboid is caught and treated early, treatment is usually successful, and individuals may begin activities such as sports when the pain subsides. If left untreated, the pain will worsen, and the condition could cause permanent damage.

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.
