Lateral column lengthening osteotomies

Lateral column lengthening procedures, either an Evans-type procedure or a calcaneocuboid distraction arthrodesis, clearly have a role to play in the management of a pes planovalgus foot deformity, as is evident from clinical outcome studies. Despite an abundance of literature intricately detailing the biomechanical effects of different operative procedures on the hindfoot, there is no clear consensus as to the best procedure or procedures to perform for a flexible pes planovalgus foot deformity. There is, therefore, no single solution to this problem; the surgeon must treat each patient as an individual and choose the procedure that will work best in their hands for any given foot pathology they are presented with. The surgeon must also be aware that to improve the kinematics of a planovalgus foot deformity, one may often have to perform multiple procedures and not a lateral column lengthening in isolation.
