Orthopaedic prosthesis with access in collar

An orthopaedic prosthesis for implanation in a bone, the prosthesis including a collar extending outwardly therefrom. The collar includes an access recess aligned above the bone cement when the stem is implanted with cement in bone, or aligned above the bone/implant interface when the stem is biologically affixed to the bone. The access recess may be a dimple partially extending into the collar or it may be a through hole. The dimple provides a preset drill start for a drill to be aligned therewith for drilling through the collar to form a hole therethrough. In either case, whether starting with a dimple and then forming a hole or starting directly with a through hole, the hole may be progressively enlarged by use of sequentially larger drill sizes. Tools, such as chisels or the like, are inserted through the hole in the collar to break up the bone cement beneath the collar if a cemented stem, or to help break the bond between the stem and the bone if a biologically affixed stem, to help loosen the prosthesis from the bone to facilitate removal of the stem. A method of removing such a prosthesis is also disclosed.
