Biomechanics in Podiatry
Biomechanics and its related study deal with forces that act against the body and effect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot itself, 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 and limit the mobility everyone takes for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area, all effecting 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 claimed that changing or controlling the forces between the ankle and the foot, 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 thermoplastic 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 not only take readings, but also map out what treatment will do to the affected areas.
Stress fractures occur in the foot and ankle when muscles in those areas are weakened from too much or too little use. When this happens, they stop cushioning the foot and ankles from the impact of hitting the ground. Because there is nothing to protect them, the bones of the foot begin to absorb the full impact of each step someone takes. The added stress causes little cracks to form in the bones that are under the most pressure. These cracks are called stress fractures.
Stress fractures are common for individuals whose daily activities cause high levels of impact on their feet and ankles. Individuals who run, play tennis or basketball, or practice gymnastics tend to experience these fractures more frequently. Anyone is susceptible to this problem, though. Individuals who are normally sedentary and suddenly begin an intensive high impact work out may get stress fractures. This is because their muscles are not strong enough to handle and cushion the intensity of their activity. Osteoporosis may also cause someone to get stress fractures, because the disease weakens an afflicted person's bones and makes it easier for them to break down.
The pain from these fractures will occur in the general area of the fracture. It may be intermittent or constant, and will cause sharp or dull pain along with swelling and tenderness. Engaging in any kind of activity, high impact or otherwise, will aggravate the pain. If the intensity of the activity increases before the stress fracture has properly healed, it can cause a full fracture. This is a much more serious problem, and will probably prevent you from applying any pressure on the foot at all.
Treatment can vary depending on the individual and the degree of injury. The primary way to treat a stress fracture is to rest the hurt foot. Some fractures will heal quickly with only a little bit of rest, while others may require a long rest period and the use of crutches. Under certain circumstances, surgery may be required to install support pins around the fracture to assist in healing.
In order to avoid getting stress fractures, make sure to get plenty of calcium and Vitamin-D. They will help to keep your bones strong, and make them less likely to break under pressure. If your new exercise regimen is running or some other kind of high impact activity, set incremental goals on a weekly basis so you can build up muscle strength. For example, if you plan to walk every day, you could ride a bike on some days to take the stress off of your feet. Make sure to wear supportive shoes to better protect you feet.
If you begin to experience any symptoms of stress fractures, you should stop exercising and rest. If the symptoms do not go away, see an orthopedic specialist. Remembering these tips can help you prevent stress fractures to your foot and ankle, and allow you to continue living normally.
All About Broken Ankles
Broken ankles are a serious injury that can lead to an inability to walk, function, and also cause a significant amount of pain. A broken ankle is actually a break in one of the three bones in your body that connect at the ankle joint, the tibia, the fibula, and the talus. The tibia and fibula are your two primary leg bones that connect at the knee, which sit directly upon the talus bone. This is protected by a fibrous membrane that allows for movement in our ankle joint. A broken ankle is usually caused by the foot rolling under or twisting too far, causing one of these three bones to snap.
A broken ankle is different from an ankle sprain, which occurs when the ligaments are ripped or torn but no bones have been broken. However, a sprain can still be very severe, causing bruising in the foot and an inability to hold your own weight, much like a broken ankle would. If you cannot stand on your own weight and suspect that you have a broken ankle, the first thing to do would be to get an immediate x-ray to determine the severity of the break.
A common way to break your ankle is to roll over onto it with enough pressure to break the bones, usually done while engaging in exercise, sports, or some other physical activity. Another common cause is a fall or jump from a large height.
Broken ankles can cause severe pain, but immediate relief can come from elevating the feet above your head to reduce blood flow to the injured area. You can also apply ice packs to the ankles to help reduce the swelling, redness, inflammation, and pain. After these initial steps, getting a cast on and staying off your feet as much as possible will aid in the recovery of the broken ankle, because the less movement and stress the ankle has to endure, the more complete it will heal. A doctor can determine if surgery is needed in order to heal correctly. In these cases, an operation may be the only option to ensure the ability to walk properly again, followed by physical therapy and rehabilitation.
It is highly important to determine if surgery is needed early on, because a broken ankle can become much more severe than you realize. If not professionally treated, the broken ankle will inhibit your walking, daily functioning, and produce a large amount of pain, so the quicker you act, the better.
Effect of High-Heels on the Feet
For hundreds of years, women have been wearing various kinds of high-heels for mostly aesthetic reasons. Women who wear high-heels appear to be taller and to have longer and thinner legs, and the wearer’s gait and posture changes. Though high-heels have had an association with femininity and have kept them popular over the years, there are definite health problems caused by wearing them too frequently.
The motion of the ankle joints is limited when heels are worn. The ankle joint is very important to the body when it comes to walking. Because of their location, these joints have a great deal of weight put on them. Thus, it is very important to keep them as healthy as possible. The Achilles tendon is the main tendon in the ankle. Wearing high-heels too often, studies have shown, can cause the calf muscle and Achilles tendon to shorten and stiffen, which can cause problems when shoes without heels are worn.
By putting a great deal of pressure on the ball of the foot, by forcing the toes into a small toe box, high-heels can cause or may worsen many foot problems, such as corns, hammertoe, bunions, Morton’s neuroma and plantar fasciitis.
Not only does wearing very high-heels regularly have negative effects on the feet, the rest of the body can suffer as well. The knees, one of the most important joints in the entire body, can be affected by wearing high-heels. High-heels causes the knees to stay bent all the time. Also, it can cause them to bend slightly inward as well. Doctors believe that women can suffer from osteoarthritis later in life because of constantly walking like this. By limiting the natural motion of the foot during walking, high-heels also cause an increased in stress on the knees.
Similarly, the back may also be affected by high-heels because it causes the back to go out of alignment. If high-heels are worn constantly, the spine’s ability to absorb shock can cause continued back pain. They can compress the vertebrae of the lower back, and can overuse the back muscles.
However, this is not to say that high-heels can never be worn. If worn occasionally, they will not cause serious problems. They should not be worn every day in order to avoid the long-term physical health problems of the feet, knees, ankles, and back like mentioned above.
