In this study, lumbar spine specimens were assigned to two groups: the CBT model group that underwent CBT screw fixation and the PS model group that underwent pedicle screw fixation. Using a six-axis material testing machine, bend and rotation tests were conducted on each model. The angular displacement from the time of no load to the time of maximum torque was defined as range of motion (ROM), and then, the mean ROM in the bend and rotation tests and the mean rate of relative change of ROM in both the bend and rotation tests were compared between the CBT and PS groups. There were no significant differences between the CBT and PS groups with regard to the mean ROMs and the mean rate of relative change of ROMs in both the bend and rotation tests. Vertebral stability after CBT fixation was similar to that after PS fixation., 2016年度～2018年度科学研究費補助金(基盤研究(C))研究成果報告書, 16K05975},
