The invention relates to an articulating joint spacer for temporary replacement of a joint, whereby the joint spacer comprises two spacer parts which each comprise one sliding surface on which the spacer parts, in the patient-inserted state, touch against each other in mobile manner and roll off on each other, and the remaining spacer parts are made, at least in part, of a second bone cement that contains at least one water-soluble antibiotic. The invention also relates to a method for producing a two-part articulating joint spacer, in which a sliding surface is formed in both spacer parts from a low-abrasion first bone cement and at least the surfaces of the remaining spacer parts, at least 50% thereof, are formed with a second bone cement that contains at least one water-soluble antibiotic. |
