ABSTRACT:
A system for reaming a cavity in bone for implantation of a prosthetic component, such as an oblong acetabular cup having an outer surface formed by adjacent hemispheres. In one embodiment, the reaming system is useful to form a second cavity in relation to an already formed first cavity. The reaming system includes an instrument with an elongate handle and a drive member coupled to a bearing plate with a locator member removably and replaceably mountable to the bearing plate. The drive member has a distal reamer mating end and a proximal end for coupling with a drill mechanism. The distal reamer mating end is axially movable toward and away from the bearing plate to ream the cavity corresponding to the secondary hemisphere of the acetabular cup to be implanted. In another embodiment, the reaming system includes a plurality of reamers each having different outer dimensions and being matable to the drive member. In a further embodiment, the system includes a plurality of locator members for positioning a respective one of the reamers to form the second cavity at a desired location.
