Abstract
A ready-for-use polymer cement spacer device for the replacement of a permanent joint prosthesis during a two-stage replacement, includes a shank includes for attachment for placing to the supporting bone and a head in the joint region. The spacer device includes two complementary members incorporating rigid members for assembly between them, the first member being loaded with a first active substance and the second member being loaded with a second active substance. The first and second active substances are preferably antibiotics, selected from gentamycin, trobamycin, vancomycin, erythromycin, fucidin, tetracycline or other suitable antibiotics. The temporary joint implant maintains a suitable space for the time necessary for the operation of replacing a permanent prosthesis to prevent tissues from occupying the space released by removal of the permanent prosthesis and ensures effective treatment of resistant infections by local treatment of the joint area through at least two different active substances.
