A system for removing bone growths and realigning bones includes a bone planer and an osteotomy guide. The bone planer includes a hollow sleeve that has an end embeddable within a bone. The bone planer also includes a rotary blade that is coupled to the hollow sleeve. The rotary blade is positioned within and rotatable relative to the hollow sleeve. The osteotomy guide includes a distal portion and a proximal portion. The distal and proximal portions are slidably coupled together. Each of the distal and proximal portions includes an upright that defines a cut guide surface. A space defined between the cut guide surfaces defines a cut path corresponding with a desired cut through the bone.
