Abstract: A cutting head for use with an intramedullary reamer is described. The reamer cutting head is of a unitary body construction that comprises a conically-shaped body having a bone cutting portion spaced from a barrel portion for attachment to a drive shaft. The bone cutting portion comprises a plurality of blades having a tissue cutting edge that outwardly extends from the cylindrical body. The plurality of blades is positioned about the cutting head in a spaced apart manner. The various plurality of blades are arranged at prescribed angular relationship that increases cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.
