简要总结
This study is to evaluate the anatomical characteristics of spondylolisthesis patients using spine ultrasound imaging. The optimal angle of spinal needle insertion for spinal anesthesia in spondylolisthesis patients was compared to that of normal patients without abnormal spinal anatomy.

结局指标
主要结局
The predicted optimal angle of spinal needle insertion for spinal anesthesia at the level of spondylolisthesis. (alpha 1)
时间窗: Preanesthesia
The needle insertion angle where the height of ligamentum flavum/dura mater complex(LFD) is measured the longest in ultrasound image.
The predicted optimal angle of spinal needle insertion for spinal anesthesia at the one upper level of spondylolisthesis. (alpha 2)
