ABSTRACT:
A reaming device for use in creating a cavity or excavation in a femoral neck which is adapted to receive an intramedullary insert, and especially an upper flange or offset of an intramedullary insert, is disclosed, as well as a method for producing such a cavity or excavation in the femoral neck, preferably in a flattened and elongated superior neck of a previously-resected femoral head. The apparatus provides a camming surface in contact with a corresponding cam follower for longitudinal manipulation of the rotatory reamer into and within the upper portion of the femoral head to create the desired cavity or excavation therein as the rotary reamer is moved back and forth generally laterally.
