Combined technique for surgical correction of pediatric severe flexible flatfoot.

Ten patients with 12 symptomatic severe flatfeet were treated with a combined surgical technique. Patients 10 years or older were treated with Evan's calcaneal osteotomy, Young tenosuspension, and tendo achillis lengthening. Patients under age 10 were treated with modified Young tenosuspension, talonavicular desmoplasty and subtalar arthroereisis. Eight of the 10 patients had marked relief in pain and fatigue and were able to perform all physical activities. Radiographic criteria showed improvement for all patients in all categories.
