Preoperative planning for posttraumatic lower limb deformity correction.

Lower limb deformities encompass a wide range of problems, and the work-up and management of these patients is quite complex. The purpose of this review was to define the essential considerations of preoperative planning for lower limb deformity correction. This can be somewhat simplified into the who, what, where, how, and why, which includes the patient evaluation, defining the deformity, finding the center of rotation of angulation, the osteotomy, the technique of distraction osteogenesis, and the goals of surgery, respectively. The goal of this review was to establish a framework of the fundamentals for preoperative planning of lower limb deformity corrections.
