Abstract
The present invention includes an apparatus and method for cutting a bone including a cutting assembly having a cutting blade, a cutting guide for guiding the shape of the cut in the bone, and a power source for powering the cutting blade. The cutting blade is moveable radially to vary the depth of the cut in the bone, and the cutting blade is capable of cutting around the circumference of the bone as well as in a longitudinal direction along the bone. A powered bone breaking device for completing the breaking of the weakened bone is also disclosed. A miniaturized version of the bone cutting apparatus can be used to cut out sections of a femur head from inside a femur body.
