Once the vertical, dorsal cut has been completed, the burr is introduced again to establish the short plantar cut. The saw bone picture demonstrates a dorsal cut where the bone loss created by the burr is compensated by angulation of the osteotomy (left). In the fluoroscopic image the orientation of the osteotomy was deliberately perpendicular to the long axis of MT1 to create a mild shortening in an index +/− situation with mild osteoarthritic changes of MTP1
