Children's feet are not small adult feet. Growing bones, developing arches, and athletic demands create unique conditions that require specialized evaluation — and often resolve beautifully with early intervention.
The pediatric foot undergoes dramatic structural change from birth through skeletal maturity. The fat-pad-filled, flexible flat arch of infancy gradually develops into a structured arch by age 6–8. Rotational alignment of the legs — which determines in-toeing and out-toeing — evolves through predictable developmental stages that can alarm parents but are usually self-correcting. Understanding what is normal, what is a developmental variant requiring monitoring, and what is a true pathological condition requiring intervention is the core skill in pediatric podiatry — and the reason that specialist evaluation matters more than internet reassurance.
Sever's disease (calcaneal apophysitis) is the most common cause of heel pain in children and adolescents, arising from traction stress on the growth plate of the calcaneus (heel bone) during periods of rapid skeletal growth. The calcaneal apophysis — the secondary ossification center to which the Achilles tendon attaches — is particularly vulnerable between ages 8 and 15, when the tendon's traction forces outpace the bone's ability to withstand them. Symptoms are typically bilateral, worsen with athletic activity, and resolve spontaneously once the growth plate fuses — but appropriate management dramatically reduces severity and keeps young athletes participating.[5] Dr. Santopietro has written specifically on foot and foot-related injuries in the young athlete, and this condition is a particular area of clinical expertise.
Other important pediatric conditions include accessory navicular (an extra bone on the inner foot causing arch pain in adolescents), juvenile idiopathic arthritis affecting the foot and ankle, ingrown toenails (often requiring conservative or minor surgical management), and tarsal coalition — a fibrous or bony bridge between two tarsal bones that presents with rigid flat foot and recurrent ankle sprains in teens and young adults. Each requires accurate diagnosis before treatment is initiated.
Other conditions in this category that Dr. Santopietro regularly evaluates and treats.
A group of avascular necrosis conditions affecting the developing bones of the foot in children and adolescents. Kohler's disease involves necrosis of the tarsal navicular, producing medial midfoot pain in children aged 3 to 7. Freiberg's infraction affects the head of the second metatarsal in adolescents and young adults, causing forefoot pain, joint stiffness, and flattening of the metatarsal head on imaging. Both conditions require offloading and activity modification; custom orthotics reduce compressive forces during the healing phase and may prevent progression to permanent joint damage.
Dr. Santopietro brings decades of experience with pediatric and adolescent foot conditions. Early evaluation provides the best window for intervention — and the most reassurance for parents.
