It is a term that includes a range of conditions that may affect the bones, tendons, and muscles of the foot. Among those most frequently treated at HSS are cavus foot, tarsal coalition, clubfoot, accessory navicular, and juvenile bunion. Treatment of foot deformities in children can vary significantly from that needed in adults. Fortunately, pediatric orthopedists who specialize in this field can bring to bear a range of non-operative and operative techniques specifically developed to address the distinctive needs of children, which include special attention to preserving the integrity of the growth plate, allowing continued growth and development of the foot.
