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.
松质骨的存在决定了跖骨截骨部位的选择。跖骨头和跖骨基底有良好的松质骨，而骨干为皮质骨且有髓腔，这使得它成为截骨部位的不佳选择。现在许多从业者采用经干骺端横向截骨术；然而，作者选择关键干骺端截骨术作为首选术式，使用连接到摆动动力源的10毫米或12毫米关键截骨刀片。
