Abstract

A method for computer-assisted planning of a transplant surgery is provided. The method includes obtaining a computer-readable representation of a donor and recipient skeletal fragment; determining surgical cutting planes on the computer-readable representation of the donor skeletal fragment from which a portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment will be harvested; determining virtual cutting guides; performing a virtual osteotomy to separate the portion of the donor skeletal fragment from the computer-readable representation of the donor skeletal fragment from a remainder portion of the donor skeletal fragment based on a position of the virtual cutting guides that are attached to the computer-readable representation of the donor skeletal fragment; positioning the donor skeletal fragment within a transplant region of the recipient skeletal fragment; and creating a hybrid computer-readable representation comprising the recipient skeletal fragment and the portion of the donor skeletal.
