Some people have always had flat feet from a young age. Unfortunately as people reach their fifties they will suddenly have one foot with a flatter arch than the other foot. This situation is termed adult acquired flatfoot. Adult acquired flatfoot is a painful condition occurring in one foot. The common patient profile is a female over the age of 50 with pre-existing flatfeet, high blood pressure, high cholesterol, diabetes and obesity. All of these underlying problems will lead to a weakening of the support structures of the arch. If you have adult acquired flat foot you will not be able to lift your heel off the ground while standing on one leg. Adult acquired flatfoot may develop due to trauma or degeneration of major tendons ankle & foot. Weakness or paralysis of leg muscles can also create a flatfoot deformity. Adult acquired flat foot can be treated with physical therapies, motion control running shoes or hiking boots, custom foot orthoses, and ankle foot orthoses.
The direct cause of being flat footed is linked to a muscular imbalance in the intrinsic muscles of the foot and ankle. When your main arch-supporting tendon, the posterior tibial tendon, decreases in strength due to muscle decay or injury, the foot begins to flatten and can cause pain during normal activities. Weakness in the tendon can be present at birth due to genetics or can develop from early walking patterns. However, in most people who experience fallen arches, it comes from strain due to aging or placed on the feet from standing or walking in heels for long periods of time. Improper footwear that doesn?t support the arch of the foot, diabetes and obesity can increase your risk of developing fallen arches.
Flat feet don't usually cause problems, but they can put a strain on your muscles and ligaments (ligaments link two bones together at a joint). This may cause pain in your legs when you walk. If you have flat feet, you may experience pain in any of the following areas, the inside of your ankle, the arch of your foot, the outer side of your foot, the calf, the knee, hip or back. Some people with flat feet find that their weight is distributed unevenly, particularly if their foot rolls inwards too much (overpronates). If your foot overpronates, your shoes are likely to wear out quickly. Overpronation can also damage your ankle joint and Achilles tendon (the large tendon at the back of your ankle).
It is important for people with foot pain to know if they have flat feet. The following tests can help you determine your arch type. When you get out of a swimming pool, look at your footprint on the concrete. The front of the foot will be joined to the heel by a strip. If your foot is flat, then the strip is the same width as the front of the foot, creating a footprint that looks like a stretched out pancake. With a normal arch, the strip is about half the width of the front of the foot. If you have a high arch, only a thin strip connects the front of the foot with the heel. Put your shoes on a flat table and view them at eye level from behind. See if the sole is worn evenly. A flat foot will cause more wear on the inside of the sole, especially in the heel area. The shoe will easily rock side to side. A flat foot will also cause the upper part of the shoe to lean inward over the sole. Both shoes should wear about the same way. If you have pain in one foot, you should make sure you don't have a fallen arch on that side. There are two good tests you can perform at home to detect this problem. Place your fingertips on a wall that you are directly facing and stand on your tiptoes on one foot. If you can't do it, a fallen arch may be the culprit. Stand with your feet parallel. Have someone stand in back of you and look at your feet from behind. You can also do it yourself if you stand with your back to a mirror. Normally, only the pinky toe is visible from behind. If one foot is flatter than the other, the 4th and sometimes the 3rd toe on that foot can also be seen.
What causes flat foot deformity?
Non Surgical Treatment
When pain results from a fallen arch, the physician may prescribe these. Rest and ice. A brace to help support the fallen arch. Physical therapy to strengthen and stretch the foot. Orthotics (arch supports) to compensate for a fallen arch. The physician may tell the patient to choose shoes that have proper arch supports and avoid non-supportive shoes such as flip-flops. If obesity contributed to the fallen arch, the patient should lose weight.
Since there are many different causes of flatfoot, the types of flatfoot reconstruction surgery are best categorized by the conditions. Posterior tibial tendon dysfunction. In this condition, the tendon connecting the calf muscle to the inner foot is torn or inflamed. Once the tendon is damaged it no longer can serve its main function of supporting the arch of the foot. Flatfoot is the main result of this type of condition and can be treated by the following flatfoot reconstruction surgeries. Lengthening of the Achilles tendon. Otherwise known as gastrocnemius recession, this procedure is used to lengthen the calf muscles in the leg. This surgery treats flatfoot and prevents it from returning in the future. This procedure is often combined with other surgeries to correct posterior tibial tendon dysfunction. Cleaning the tendon. Also known as tenosynovectomy, this procedure is used in the earlier and less severe stages of posterior tibial tendon dysfunction. It is performed before the arch collapses and while the tendon is only mildly affected. The inflamed tissue is cleaned away and removed from the remaining healthy tendon. Tendon transfer. This procedure is done to correct flatfoot and reform the lost arch in the foot. During the procedure, the diseased tendon is removed and replaced by tendon from another area of the foot. If the tendon is only partially damaged, the inflamed part is cleaned and removed then attached to a new tendon. Cutting and shifting bones. Also called an osteotomy, this procedure consists of cutting and reconstructing bones in the foot to reconstruct the arch. The heel bone and the midfoot are most likely reshaped to achieve this desired result. A bone graft may be used to fuse the bones or to lengthen the outside of the foot. Temporary instrumentation such as screws and plates can also be used to hold the bones together while they heal.
