ABSTRACT:
An osteotome includes an arcuate cutting blade portion and a planar cutting blade portion integrally secured thereto. The arcuate portion is defined from a locus of a perfect circle and is axially elongated relative to the planar blade so as to permit the arcuate blade to be reained within an initially cut portion of a bone while the entire osteotome is rotated to a new, second position in order to perform a second cutting of the bone. The two cuttings of the bone serve to remove a section of the original bone, and in this manner, when the bone sections are repositioned relative to one another, the same will be precisely aligned so as to correct the original bone deformity. The arcuate portion also includes a stepped portion so as to facilitate the rotational positioning of the osteotome in either direction to the second position relative to the first position, and various indicating devices can also be provided so as to visually indicate the precise amount the instrument is to be rotated between the cutting positions.
