[Flatfoot in children].

The diagnosis of flatfoot in children is made clinically. In most cases it is an age-appropriate benign physiological variant, as long as it can be passively and actively redressed and the child does not show any neurological abnormalities, especially under the age of 6 years. Treatment is only indicated for symptomatic variants. In the case of rigid flatfeet, further diagnostics are necessary to exclude neurological or structural causes. Subtalar arthroereisis has become established and is an effective but slightly invasive procedure. Further options include the lengthening and medial translational osteotomy of the calcaneus or the Cotton operation; however, the indications must always be critically questioned, especially for surgical but also for conservative treatment, even if it is the wish of the family.
