| Abstract: | Objective To compare stability of expansive pedicle screw(EPS) and polymethylmethacrylate-augmented pedicle screw(PMMA-PS) in vitro in sheep lumbar vertebrae.Methods Sixty adult sheep lumbar vertebrae were randomly divided into three groups.A pilot hole was prepared in advance using the same method in all samples.Then,conventional pedicle screw(CPS) was inserted in CPS group,the pilot hole was filled with PMMA followed by insertion of CPS in PMMA-PS group and EPS was inserted in EPS group.Twenty four hours ... |
