Abstract
A powered bone cutting saw is used from within the intramedullary canal of a bone. A cutting blade is inserted through a bored intramedullary canal to a predetermined cutting depth. A motor is coupled to the cutting blade to rotate the cutting blade. The blade is extended to a cutting position and operated by a surgeon to cut the bone radially from the inside outwardly, transversely, to the intramedullary canal. Gearing selectable by the surgeon permits the blade to oscillate. The motor can also be coupled to a reamer tip for boring the intramedullary canal. The apparatus, including the reamer tip, can be cannulated to accept a guide wire.
