Abstract:
A cutting tool for preparing a femur for the receipt of an implantable prosthesis comprising a rotatable drive member adapted for removable coupling to a motor unit of a power assembly, with the tool being adapted to be received interiorly of the intramedullary canal of the femur and including a cylindrical-like cutter secured to the drive member for cutting into a confronting interior surface of the femur canal, together with shoulders on both sides of the cutter for limiting the depth of groove produced by the cutter upon rotation of the tool and movement of the cutter laterally into engagement with the canal surface. The canal is adapted to receive surgical cement in which the prosthesis is embedded, and with the cement entering the formed grooves in the interior surface of the canal for aiding in firmly anchoring the prosthesis in the canal upon hardening of the cement. A novel method for preparing the femur for the receipt of an implantable prosthesis by forming grooves therein is also disclosed.
