Anterior calcaneal osteotomy for symptomatic juvenile pes planus.

Five patients with symptomatic flexible pes planus unresponsive to conservative therapy underwent nine open wedge anterior calcaneal osteotomies and advancement of the posterior tibial tendon. The average follow-up was 6 years, 8 months. Three patients exhibited medial and plantar talonavicular subluxation and naviculocuneiform sag. There were three excellent results, three very good, two good, and one poor. The patient with a poor rating was asymptomatic, had normal foot motion, and was satisfied with the procedure.
