目的：通过实地解剖对腰神经根的走行观察及相关测量，为分析临床疾病提供依据，为解剖学数据提供资料。方法12具成人尸体标本，逐层分离暴露硬膜囊及两侧神经根，并进行相关观察与测量。结果 L1到L5神经根不断变长，L5最长，为（12.25±3.66）mm（左）、（12.83±2.81）mm（右）；粗度不断增加，L5最粗，为（3.82±0.88）mm （左）、（3.89±0.95）mm（右）；L1到L5神经根角逐渐变小，从（44.33±10.36）°（左）、（42.12±10.42）°（右）减小到（27.33±8.15）°（左）、（27.50±8.25）°（右）。结论L1到L5神经根中轴与硬膜囊中线之间的角度逐渐变小，神经根由硬膜囊“腋部”穿出处至神经节近端之间的长度逐渐增加，神经根的粗度逐渐增加。

Objective To carry anatomical observation and measure on L1 to L5’s length from dural sac’s“axilla”to near-end of ganglion, roughness of nerve root, angle between nerve root axis and midcourt line of dural sac and analyse the clinical signiifcance of nerve roots. Methods In 12 bodies fastened by formalin, we took out vertebral plate in the lumbar vertebra’s superior articular process and inferior articular process with scalpel and lamina impingement rongeur, exposed bilateral dural sac and nerve roots. Isolate nerve roots of L1-5, and conducted elevant observation and measure. Results The nerve root become longer and longer from L1 to L5, L5 was the longest, achieving (12.25±3.66) mm(left), (12.83±2.81) mm(right);roughness become rougher, L5 was the roughest, reaching (3.82±0.88) mm(left), (3.89±0.95) mm(right). The angle of nerve roots became smaller, from (44.33±10.36)°(left), (42.12±10.42)°(right) to (27.33±8.15)°(left), (27.50±8.25)°(right). Conclusion From L1 to L5, the angle between nerve root axis and midcourt line of dural sac become smaller. The length from dural sac’s“axilla”to near-end of ganglion become longer. The roughness of nerve root become rougher. There is no obvious difference between left and right.
