Claim:
An implant system comprising: a prosthetic implant; a spacer sized for use with said prosthetic implant, said spacer including at least one outer surface formed from hardened bone cement, said spacer having a contrast agent incorporated therein at a first concentration chosen to achieve a first contrast; and a curable fixative locatable between said spacer and said prosthetic implant to secure said spacer to said prosthetic implant, said curable fixative having a contrast agent incorporated therein at a second concentration chosen to achieve a second contrast, wherein said first concentration of the contrast agent in said spacer differs from said second concentration of the contrast agent in said curable fixative such that said first contrast differs from said second contrast to facilitate differentiating said spacer and said curable fixative from each other along said at least one outer surface of said spacer and to facilitate differentiating said spacer and said curable fixative from their surroundings.
