Treatment of Symptomatic Pediatric Flexible Flatfoot

Abstract

Background: Pediatric flexible flatfoot is a common musculoskeletal condition characterized by collapse of the medial longitudinal arch during weight-bearing, with restoration of the arch when the foot is unloaded or during tiptoe standing. In most children, flexible flatfoot is physiological, asymptomatic, and tends to improve spontaneously with growth and maturation. However, symptomatic cases may present with pain along the medial longitudinal arch or sinus tarsi, early fatigue, reduced endurance, gait abnormalities, heel-cord tightness, and limitations in daily or sports activities. Despite its high prevalence, the optimal management of symptomatic pediatric flexible flatfoot remains controversial because there is no universal agreement regarding the appropriate age to initiate treatment, the most reliable diagnostic methods, or the effectiveness of the available therapeutic options. Careful clinical assessment is essential to differentiate flexible from rigid flatfoot and symptomatic from asymptomatic cases. Conservative treatment represents the first-line approach and includes patient and parental education, activity modification, supportive footwear, foot orthoses, stretching and strengthening exercises, and nonsteroidal anti-inflammatory medications when inflammation or pain is present. Surgical intervention is reserved for children with persistent pain and functional impairment despite adequate nonsurgical treatment. Available surgical procedures include soft-tissue reconstruction, calcaneal osteotomies, arthrodesis, and subtalar arthroereisis. Treatment should be individualized according to the child’s age, symptoms, severity of deformity, associated conditions, and response to conservative management.
