Bone Cutting Instruments
All amputations of the extremities involve cutting through the central bone of the limb, thus the need for a saw. These instruments have teeth on their cutting edge to facilitate cutting through bone.
• Fergusson amputation saw (Fig. 8.10)
• Adams-Jones saw (Fig. 8.11)
• Stryker oscillating saw (Fig. 8.12)
• Gigli saw (Figs 8.13A and B).
Other Bone Cutting Instruments
• Chisels are sharp bone cutting instruments beveled on one side only, thus it cannot cut deep into a bone. Smith-Peterson chisel (Fig. 8.14) beveled one side.
• Osteotomes are sharp instruments beveled on both sides and thus can split a bone. McEwan osteotome (Fig. 8.15) beveled both sides.
• A gouge has a curved cutting edge and like a chisel can be used to create a surface cavity on a bone. Smith-Peterson gouge (Fig. 8.16).
