Abstract
A reamer for reaming a uniform opening in an intramedullary canal of a bone. The reamer has an impeller rigidly attached to the shaft of the reamer proximal to the reamer head. The impeller blades have a pitch higher than the pitch of the reamer head flutes. The increased pitch between the impeller blades and the reamer head flutes produces a partial vacuum while the unit is turning, pulling debris up and out of the bony canal and reducing pressure in the intramedullary canal.
