Objective This study aimed to provide anatomical basis for clinical applied anatomy by measuring the cauda equina, and to accumulate data for investigation on Chinese physical fitness. Methods We measured length, diameter, rootlet number and dural hole number of L1～L5 segments of the cauda equina on 30 intact formalin-fixed specimens. Results The length of cauda equina increased from L1 to L5. The dorsal root's diameter is bigger than the diameter of ventral root. The largest ventral root is L3 and the diameter of dorsal root increased from L1 to L5. The number of nerve rootlets of dorsal root is significantly more than ventral roots'. Most of the dural hole number of L1～L5 segments is 1. The dural hole number of L3 level greater than 1, which is more than other levels. Conclusion The measurement of cauda equina accumulates data for investigation on Chinese physical fitness and provides anatomical basis for diagnosis and treatment of cauda equina syndrome, and clinical anesthesia.
