Flatfoot (Pediatric)

A flatfoot deformity is where the arch on the inside border of the foot is more flat than normal. Flatfoot deformities can occur in all age groups, but appear most commonly in children. Some of these children grow up into adults who have feet with normal arches, but many of these children have pain related to their flatfoot deformity throughout their lives. It is very important that children with flatfoot deformity be evaluated by a podiatrist to determine if they need treatment to prevent future pain or deformity in their feet.

When the young child starts to first walk at about the age of 9-15 months of age, the foot has a fat or chubby appearance where there is a less bony architecture apparent in the foot. At this point in the development of the foot, it is very difficult to evaluate whether the child will have future problems with a flatfoot deformity.

Diagnosis

As mentioned above, the pediatric flatfoot deformity can be diagnosed at a very early age, but is unlikely to be properly diagnosed unless the doctor is a foot specialist, like a podiatrist, and is familiar with the intricacies of the structure and biomechanics of the foot. After speaking with the parent and child, the podiatrist will examine the foot both while the child is not bearing weight but also while the child is standing, walking or running. Often, the family history is also taken since the foot should be examined closely if the child has a close relative who had a painful flatfoot deformity as a child or adult.

During the examination of the child, the podiatrist is looking for abnormal structure or function of the foot and lower extremity, which could lead to either problems during childhood or adulthood. X-rays may be taken of the foot if a significant pathology is noted or suspected. The more severe the flatfoot deformity and the more significant the complaints in the foot or lower extremity, then the more likely the podiatrist will recommend specific treatment for the flatfoot deformity.
