The presence of cancellous bone determines the choice of location for osteotomies in the metatarsals. The head and base have good cancellous bone, whereas the shaft has cortical bone and a medullary canal which make it a poor choice of osteotomy site. Many practitioners are now using a transverse metaphyseal osteotomy; however, the authors choose the pivotal metaphyseal osteotomy as the procedure of choice using a 10- or 12-mm Pivotal Osteotomy Blade attached to an oscillating power source.
