Flat feet—which can be described as a reduction or disappearance of the foot’s inner arch (medial longitudinal arch) while standing or walking—is one of the leading foot problems that concern parents during childhood and adolescence. This condition, which can be observed physiologically in many children up to age 5 and generally does not indicate a specific pathology, tends to diminish and disappear with age. However, if it persists beyond the age of 8, surgical correction may occasionally be necessary.
Flatfoot that occurs outside the scope of physiological flatfoot and is observed in older age groups can be classified into two types: flexible and rigid flatfoot. While observation and exercise therapy are sufficient in most cases of flexible flatfoot, cases of rigid flatfoot often involve an underlying musculoskeletal pathology, and surgical intervention may be necessary in these instances. You are viewing follow-up radiographs of two cases we treated using a surgical modification we published in the *Journal of Pediatric Orthopedics* in 2016.
