Calcaneal Z osteotomy for extra-articular correction of hindfoot valgus.

The lateral column lengthening procedure has been used in the surgical management of congenital and adult-acquired pes planus. Lateral column lengthening allows correction of the abducted forefoot and subsequent improvement in the medial longitudinal arch. However, owing to the inconsistent healing times and complications, we opted to pursue a novel approach to the lateral column lengthening procedure, the calcaneal Z osteotomy.
