Implantation of a static, non-articulating cement spacer.
After diagnosis of infection and informed consent, patients will be taken to the operating room. After anesthetization, patients will be randomized to either an articulating spacer or static spacer. Randomization will be performed by prepared opaque envelopes administered by a nonparticipant in the study. After a complete debridement of devitalized tissue, explantation of infected components and any associated cement, either an articulating or static spacer will be placed. All spacers will be formed using 3.0 g of Vancomycin and 1.0 g of Tobramycin for each 40 g packet of cement. Static spacers will be hand-made with a rod of antibiotic-impregnated cement and cement beads of sufficient quantity to fill the acetabulum.

All spacers will be formed using 3.0 g of Vancomycin and 1.0 g of Tobramycin for each 40 g packet of cement. Articulating spacers will be formed of antibiotic-impregnated cement using the Stage One system (Biomet, Warsaw, IN) sized to fit the endosteal and acetabular bone defect.
