Osteotomes, Chisels and Gouges: How to Tell Them Apart and Specify Them

Osteotome vs chisel: the bevel is the difference

The practical distinction between an osteotome and a chisel is the grind of the cutting edge. A chisel is ground on one side only, with a flat back, so it cuts and also tends to steer toward the flat side. That is useful when taking a controlled slice of bone or shaping a surface. An osteotome is ground symmetrically on both faces, so it splits straight through bone with little tendency to deviate.

Naming is not always consistent between catalogues and countries. Some suppliers file every straight blade under chisel. When ordering, do not rely on the name alone: ask for a drawing or a description of the bevel, the blade thickness and the overall length.

Bone gouge: the curved cross-section

A gouge has a blade with a concave, channel-like cross-section instead of a flat one. It scoops and removes bone rather than splitting it, and is used to hollow out cavities, remove cancellous bone, clear bone graft sites or round off a prominence. Gouges come with the channel on the inside of the curve and in different radii, so a narrow, deep gouge removes bone differently from a wide shallow one.

In many orthopaedic sets a gouge and a straight chisel of the same width are paired. The straight blade defines the cut line and the gouge clears the bone.

Lambotte, Smith-Petersen and Hibbs osteotomes

Pattern names describe the design. The Lambotte osteotome is a straight, robust blade, available in a range of widths, used for fracture and osteotomy work throughout the skeleton. The Smith-Petersen osteotome has a curved blade and is used in spine and hip surgery. The Hibbs osteotome has a wider, flatter profile and is associated with spinal fusion preparation and graft harvesting. Confirm each pattern against the manufacturer's drawing, because small variations exist.

REDA lists Lambotte, Smith-Petersen and Hibbs osteotomes and gouges in its orthopaedic instrument range, together with bone curettes, rongeurs, bone levers and periosteal elevators. For a wider view see orthopaedic instruments names and uses.

Selection criteria: width, length, handle and material

Blade width is the first parameter, usually quoted in millimetres. Narrow blades suit small bones, hand surgery and facial work, wide blades suit long bones and spinal grafts. A sensible set carries several widths rather than many of one.

Strike surface and handle matter because the instrument is hit with a mallet. Look for an instrument that is forged in one piece or has a securely fixed metal handle, with a head that resists mushrooming. Cutting edges should be hard enough to hold an edge but not brittle, and the surface finish should be uniform so debris does not collect.

• Bevel: single (chisel) or double (osteotome), or concave (gouge)
• Width in millimetres and overall length
• Strike head and handle construction
• Stainless steel grade and passivation, see our note on surgical stainless steel grades
• Compatibility with your mallets and sterilisation trays

Care, sharpening and common mistakes

Bone-cutting edges dull with use and must be inspected before every case. A dull osteotome needs more force, crushes bone and raises the chance of fracture lines running in unintended directions. Arrange periodic sharpening by a qualified service and keep a record of the last service date. See instrument repair and sharpening.

Common purchasing mistakes include buying one width only, mixing instruments from different suppliers without checking the bevel, and storing the edges loose in trays where they contact other instruments. Use protective sleeves or dedicated tray positions.
