Overview
There's an easy way to tell if you have flat feet. Simply wet your feet, then stand on a flat, dry surface that will leave an imprint of your foot. A normal footprint has a wide band connecting the ball of the foot to the heel, with an indentation on the inner side of the foot. A foot with a high arch has a large indentation and a very narrow connecting band. Flat feet leave a nearly complete imprint, with almost no inward curve where the arch should be. Most people have "flexible flatfoot" as children; an arch is visible when the child rises up on the toes, but not when the child is standing. As you age, the tendons that attach to the bones of the foot grow stronger and tighten, forming the arch. But if injury or illness damages the tendons, the arch can "fall," creating a flatfoot. In many adults, a low arch or a flatfoot is painless and causes no problems. However, a painful flatfoot can be a sign of a congenital abnormality or an injury to the muscles and tendons of the foot. Flat feet can even contribute to low back pain.
Causes
Many health conditions can create a painful flatfoot, 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.
Symptoms
The symptom most often associated with AAF is PTTD, but it is important to see this only as a single step along a broader continuum. The most important function of the PT tendon is to work in synergy with the peroneus longus to stabilize the midtarsal joint (MTJ). When the PT muscle contracts and acts concentrically, it inverts the foot, thereby raising the medial arch. When stretched under tension, acting eccentrically, its function can be seen as a pronation retarder. The integrity of the PT tendon and muscle is crucial to the proper function of the foot, but it is far from the lone actor in maintaining the arch. There is a vital codependence on a host of other muscles and ligaments that when disrupted leads to an almost predictable loss in foot architecture and subsequent pathology.
Diagnosis
It is of great importance to have a full evaluation, by a foot and ankle specialist with expertise in addressing complex flatfoot deformities. No two flat feet are alike; therefore, "Universal" treatment plans do not exist for the Adult Flatfoot. It is important to have a custom treatment plan that is tailored to your specific foot. That starts by first understanding all the intricacies of your foot, through an extensive evaluation. X-rays of the foot and ankle are standard, and MRI may be used to better assess the quality of the PT Tendon.
Non surgical Treatment
Icing and anti-inflammatory medications can reduce inflammation and physical therapy can strengthen the tibial tendon. Orthotic inserts that go inside your shoes are a common way to treat and prevent flatfoot pain. Orthotics control the position of the foot and alleviate areas of pressure. In some cases immobilization in a cast or walking boot is necessary to relieve symptoms, and in severe cases surgery may be required to repair tendon damage.
Surgical Treatment
For those patients with PTTD that have severe deformity or have not improved with conservative treatments, surgery may be necessary to return them to daily activity. Surgery for PTTD may include repair of the diseased tendon and possible tendon transfer to a nearby healthy tendon, surgery on the surrounding bones or joints to prevent biomechanical abnormalities that may be a contributing factor or both.
