Abstract
A centralizer 10 for positioning against a prosthetic implant 1. The centralizer 10 includes a plurality of inner raised ribs 15 extending from the inner surface 13 of the centralizer 10. The inner ribs 15 provide inner recessed pathways 16 which extend from the distal edge 12 toward the proximal edge 11. The centralizer 10 also may include a plurality of outer raised ribs 17. The inner and outer ribs 15 and 17 space the centralizer 10 from the implant 1 and the bone 5. This allows bone cement to flow into the gaps created between centralizer and the implant and between the centralizer and the bone.
