Biomaterials can increase bone-implant interface stability. In this study four cortical screws were inserted in both 3rd metacarpal and 3rd metatarsal bones of 6 horses with calcium(Ca)-cement, magnesium(Mg)-cement, polymethylmethacrylate (PMMA) or left untreated. Specimens were harvested for analysis 5 or 182 days postoperatively. Radiography, biomechanical testing, histomorphometry and micro computed tomography were performed to characterize the bone-implant interfaces. Mg-cement significantly increased the extraction torque compared to control and Ca-cement and interface toughness compared to control, Ca-cement and PMMA. This improved interface strength was also observed during the 6 month follow-up period as one of the untreated screws and one Ca-treated screw backed out. Histologically there was 44% reduction in the quantity of Ca-cement and 69% reduction in the quantity of Mg-cement at 182 days. These results suggest that Mg-cement is a biodegradable bone cement, which can improve the biomechanical strength of the bone-implant interface.
