Patent ID: 8518045

Claim:
A method of using a spherical osteotomy device for performing spherical osteotomies, the method comprising: defining a center point of rotation through a single bone to be sectioned; oscillating a cutting end of the spherical osteotomy device about an origin of the spherical osteotomy device with a driver operably secured to the spherical osteotomy device; engaging the cutting end of the spherical osteotomy device with the bone to be sectioned; sectioning the single bone, in a single pass of the spherical osteotomy device through the single bone, by passing the cutting end of the spherical osteotomy device through the bone while rotating the spherical osteotomy device and the driver about the center point of rotation to form two bone sections from the single bone, the sectioning comprising: forming a first bone section of the two bone sections to have a convex surface having a constant radius from the center point of rotation; and forming a second bone section of the two bone sections to have a concave surface having a constant radius from the center point of rotation; self-guiding the spherical osteotomy device through the single bone by rotating an inner surface of the spherical osteotomy device having a constant radius from the origin of the spherical osteotomy device along a portion of the single bone through which the cutting end of the spherical osteotomy device has already passed; and reorientating the first bone section and the second bone section at a desired alignment relative to each other in three-dimensions without a gap between the first bone section and the second bone section in a direction along the length of the bone.
