For cutting bones different tools and techniques are available. The question which method is most advantageous depends on the basic surgical concept, the location of the bone cut and the choice of the subsequent implant. The biological activity of the anatomical site of the cut determines how much the tissue needs to be protected, taking into consideration the vascularity of the bone and avoiding heat transfer. The surgical approach depends on the implant and should be used also for the bone cut. Specific indications are given for the oscillating saw, the Gigli saw, the osteotome, drill holes and the medullary saw.
