Flatfoot in infants and children presents in two main types: rigid (fixed) and flexible flatfoot.

Rigid Flatfoot:
This condition typically manifests at birth, leading to a "rocker-bottom foot" appearance. It often results from a misalignment of one of the ankle bones (vertical talus) and can be associated with other skeletal abnormalities. Definitive diagnosis is made through physical examination.
While conservative treatments such as stretching exercises and casting can be applied in the neonatal period, surgical intervention is frequently required between 6 and 12 months of age. If left untreated, rigid flatfoot can lead to permanent disabilities. Therefore, it is crucial to initiate appropriate treatment without delay once it is identified. Early diagnosis and treatment significantly increase the chances of successful outcomes, whereas in advanced cases, treatments can become more complex.

Flexible Flatfoot:
More commonly observed in the general population, flexible flatfoot often does not require medical intervention. However, it is essential to consult an orthopedics and traumatology specialist to differentiate between flexible and rigid flatfoot.
Flexible flatfoot itself cannot be permanently corrected by treatment. In non-severe cases, it may resolve spontaneously as the foot develops. While insoles, orthopedic shoes, and exercises have been traditionally recommended, current scientific research indicates that these methods do not have a corrective effect on flexible flatfoot. However, insoles, orthopedic shoes, and exercises can be used to alleviate secondary symptoms such as pain or easy fatigue caused by flexible flatfoot.
The severity of flexible flatfoot can vary from person to person. In severe cases, a prominence may be observed on the inner side of the foot; this can lead to shoe irritation or callus formation. To prevent such secondary problems, insoles or orthopedic shoes can again be beneficial. When children are diagnosed with flexible flatfoot, regular follow-up without the need for any intervention is often sufficient until they reach approximately 7-8 years of age.
In children experiencing symptoms like pain or easy fatigue, flexible flatfoot may be more severe, and in these situations, the use of insoles is recommended. Although flexible flatfoot usually does not require surgical treatment, surgical intervention may be necessary in some advanced cases. These surgeries can include soft tissue procedures, as well as bone surgeries such as lengthening, reshaping of bones, or in some instances, fusion of joints in the foot. The aim of these treatments is to enable the patient to continue their daily life without pain.
