Subtalar arthrorisis and associated procedures.

Not all flatfeet require surgical correction. Through a careful history obtained from the child's parents, useful clues may be gathered pertaining to the disability arising from the flatfoot. There are three distinct classifications of flexible pes pronatus that require specific procedures for correction of the primary deformity. The STA-Peg, alone or in combination with other medial arch procedures, is used for correction of hindfoot pronation in the coronal planar dominant foot. The postoperative disability associated with the STA-Peg is relatively minimal, and complications are usually due to improper insertion of the implant.
