| Research Abstract |
The pedicle screw and rod system is widely used for surgical treatments of spinal disorders. Although the long-term clinical outcomes of their treatments have demonstrated that adjacent segmental diseases such as disk degeneration and slipping may be occasionally occurred, the cause of adjacent segmental diseases is unknown. Therefore, we conducted the rotational test using multi-segment lumbar spine of wild boar cadaver specimens. At the result of this study, the ROMs (range of motion) of adjacent segments and loaded maximum torque in the fixed model were significantly increased in comparison with the injured model under the constant angular displacement.
