Callus distraction in reconstructive foot surgery

Though by no means a new concept, the science of callus distraction has stimulated significant interest among surgeons over the past several years. As our knowledge and understanding of the principles of this technique have evolved, the clinical indications have been expanded. In this manuscript, we will illustrate several examples of these broadened indications. An innovative alternative to the Evans opening wedge calcaneal osteotomy, which usually requires bone graft or bone graft substitutes, is presented.
