What Is Pes Planus?

Overview

Flat Feet

If you have flat feet, your arches are low or maybe even absent. The condition is also known by the medical terms "pes planus" or "pes valgus." Flat feet are often associated with excessive pronation, which is the action that causes the foot's arch to descend down and inward (flattening) as the foot strikes the ground. Pronation is a normal and necessary foot motion. Overpronation, however, means that feet pronate to an excessive degree while standing, walking or running. Because of their tendency to overpronate, flat feet are less able to absorb shock. And this impaired shock-absorption can mean increased stress on the feet, ankles and knees. You can sometimes identify overpronation in a person with flat feet by observing them from behind. You may see something called the "too-many-toes" sign, where the individual's toes and forefeet splay outward.




Causes

Inflammatory arthritis, such as rheumatoid arthritis, can cause a painful flatfoot. This type of arthritis attacks not only the cartilage in the joints, but also the ligaments that support the foot. Inflammatory arthritis not only causes pain, but also causes the foot to change shape and become flat. The arthritis can affect the back of the foot or the middle of foot, both of which can result in a fallen arch. An injury to the ligaments in the foot can cause the joints to fall out of alignment. The ligaments support the bones and prevent them from moving. If the ligaments are torn, the foot will become flat and painful. This more commonly occurs in the middle of the foot (Lisfranc injury), but can also occur in the back of the foot. In addition to ligament injuries, fractures and dislocations of the bones in the midfoot can also lead to a flatfoot deformity. People with diabetes or with a nerve problem that limits normal feeling in the feet, can have arch collapse. This type of arch collapse is typically more severe than that seen in patients with normal feeling in their feet. This is because patients do not feel pain as the arch collapses. In addition to the ligaments not holding the bones in place, the bones themselves can sometimes fracture and disintegrate, without the patient feeling any pain. This may result in a severely deformed foot that is very challenging to correct with surgery. Special shoes or braces are the best method for dealing with this problem.




Symptoms

Flat feet may not cause any symptoms at all. Rigid flat feet may cause pain, calluses, blisters, or skin redness on the inner side of the foot. A stiff foot, weakness or numbness of the foot, Rapid wearing out of shoes-worn shoes lean in toward each other. Difficulty or pain with activities like running-in the foot, knee or hip.




Diagnosis

You can always give yourself the ?wet test? described above to see whether you have flat feet. Most people who do not notice their flat feet or have no pain associated with them do not think to see a foot doctor. Flat feet can lead to additional problems such as stiffness or pain, however, especially if the condition appears out of nowhere. If you think you may have flat feet, you should seek medical attention to ensure there are no additional issues to worry about. Your doctor will be able to diagnose you with a number of tests. For example, he or she may have you walk around, stand still, or stand on your tiptoes while you are being examined. Your doctor may also examine your foot?s shape and functionality. It?s important to let your foot doctor know about your medical and family history. In some cases, your doctor may order imaging tests such as x-rays or an MRI (magnetic resonance imaging) to determine a cause of your flat foot. If tarsal coalition is suspected in children, a CT scan is often ordered.




Non Surgical Treatment

Have you found yourself in the store looking at all the different foot care products? There is everything from massaging gel insoles to foam arch supports and heel cushions. If your arches fall the same amount on each side, you might be able to use an insert off the shelf. If they fall differently, then a generic insert will not fix the imbalance. If you have a high arch, a generic insert will likely not be high enough for full correction. Good custom orthotics provide a number of advantages over the generic inserts that you find in the store. Custom orthotics can take into account your body weight and degree of flexibility in your foot, not someone else?s. They also account for the anatomical differences in your feet. The corrected height of one arch is often higher in one foot than the other. A G-Laser foot analysis can provide you with this information.




Surgical Treatment

Acquired Flat Feet

A combination of surgical procedures can be used to reconstruct the flatfoot. Generally, these procedures can be separated into those that correct deformities of the bones and those that repair ligaments and tendons. Your orthopaedic surgeon will choose the proper combination of procedures for your foot. Surgery of the foot can be performed under regional anesthesia, which is numbing the foot and ankle with a nerve or spinal block, or general anesthesia, which may require a breathing tube. A nerve block is often placed behind the knee to reduce pain after surgery.




Prevention

oll away pain. If you're feeling pain in the arch area, you can get some relief by massaging the bottom of your foot. A regular massage while you're watching TV can do wonders" Stretch out. Doing the same type of stretching exercises that runners do in their warm-up can help reduce arch pain caused by a tight heel cord. One of the best exercises is to stand about three feet from a wall and place your hands on the wall. Leaning toward the wall, bring one foot forward and bend the knee so that the calf muscles of the other leg stretch. Then switch legs. Stretching is particularly important for women who spend all week in heels and then wear exercise shoes or sneakers on weekends. Get measured each time you buy new shoes. Don't assume that since you always wore a particular size, you always will. Too many people try to squeeze into their 'regular' shoe size and wind up with serious foot problems or sores on their feet. When your arch is falling, your feet may get longer or wider and you may or may not feel pain, so getting your foot measured each time you buy shoes is a good indicator of your arch's degeneration. Examine your shoes. If the heel is worn down, replace it. But if the back portion of the shoe is distorted or bent to one side, get yourself into a new pair of supportive shoes like those made specifically for walking. That's because flat feet can affect your walking stride, and failing to replace worn shoes may lead to knee or hip pain.




After Care

Time off work depends on the type of work as well as the surgical procedures performed. . A patient will be required to be non-weight bearing in a cast or splint and use crutches for four to twelve weeks. Usually a patient can return to work in one to two weeks if they are able to work while seated. If a person's job requires standing and walking, return to work may take several weeks. Complete recovery may take six months to a full year. Complications can occur as with all surgeries, but are minimized by strictly following your surgeon's post-operative instructions. The main complications include infection, bone that is slow to heal or does not heal, progression or reoccurrence of deformity, a stiff foot, and the need for further surgery. Many of the above complications can be avoided by only putting weight on the operative foot when allowed by your surgeon.
