Bone preparation apparatus and method

A bone preparation tool for preparing an in-patient bone with a primary motion in a primary mode of freedom of motion, comprising:

• a bone-processing implement configured to process the in-patient bone with the primary motion in the primary mode of freedom of motion;
• a motive system, coupled to said bone-processing implement, configured to operate said bone-processing implement, said motive system for operating said bone-processing implement in the primary mode of freedom of motion, said motive system further configured to operate said bone-processing implement in a secondary motion in a secondary freedom of motion, and said motive system additionally further configured to superimpose said motions in said modes of freedom of motion producing a superimposed motion, wherein the primary motion and said secondary motion are superimposed by said motive system before an application of said superimposed motion to said bone-processing implement, and wherein one of the primary motion and secondary motion includes a driven vibratory motion;
• wherein said bone-processing implement includes a saw blade and wherein the primary mode of freedom of motion includes a sagittal reciprocating motion.
