ABSTRACT:
The set of implants and method of this invention provide for the conversion of an implant 10 intended for cemented fixation to a bone to an implant 10' intended for non-cemented fixation to a bone. The set of implants include a plurality of pads 20 each having a porous surface layer 24 bonded to a plate 22. A thin layer 30 of thermoplastic polymer is bonded to the opposite side of the plate 22. The implant 10 is provided with a generally smooth outer surface and is intended for cemented use for fixation to the bone. However, if during surgery, the surgeon determines that the patient may be better suited for a non-cemented implant, the modular porous pads 20 may be bonded to the implant 10 to form an implant 10' intended for non-cemented fixation to the bone.
