Triple Arthrodesis with Lateral Column Lengthening for Treatment of Severe Planovalgus Deformity *

Abstract

Triple arthrodesis with lateral column lengthening through the calcaneocuboid joint was performed on 22 feet in 14 patients. The primary indication for surgery was severe symptomatic planovalgus deformity unresponsive to conservative measures. All patients achieved solid fusion within 12 weeks. No patient had a decline in ambulatory status. Excellent correction of deformity was achieved and maintained with an average correction of the talus first metatarsal angle of 25° in both the AP and lateral planes. Triple arthrodesis with lateral column lengthening provides for reliable arthrodesis and allows correction of severe planovalgus deformity while maintaining foot length.
