The invention relates to a spacer (1) comprised of individual components (2 3 4 9 10 12) as joint replacement in the arthroplasty of shoulder knee and hip for the temporary surgical care of infections in the joint. The problems addressed by the invention are those of avoiding an adhesion of the bone to the spacer and a release of wear products achieving that the patient does substantially not experience any mobility restriction and keeping the wear and tear of the spacer as little as possible. These problems are solved in that at least one component of the spacer (1) is made of a ceramic material of a plurality of ceramic materials or of a non ceramic material having a ceramic coating.
