摘要
目的通过对腰椎弓根及其毗邻神经结构的解剖和影像学观察,进一步明确腰神经根与椎板的解剖关系。方法取甲醛浸泡的12例(24侧)成人男性防腐尸体标本,进行解剖学观察,测量腰神经根起点至后正中线、至对应椎板上、下缘的距离和神经根与后正中线的交角。结果腰1和腰5神经根起点至后正中线距离分别为12.6±2.1mm和8.8±1.1mm,从腰1～腰5呈递减趋势;腰1和腰5神经根起点至对应椎板下缘的距离分别为14.7±2.1mm和22.3±5.0mm,从腰1～腰5逐渐增大;腰1～腰3神经根起点在对应椎板的上下缘之间,且与椎板上缘的距离逐渐减小,腰4、5神经根起点在对应椎板上缘的上方,且距离逐渐增大。结论腰椎神经根起点与相应椎板间存在渐变的解剖关系。
Objective The lumbar pedicle and its adjacent neural anatomy structures were observed in order to evaluate the anatomical relationship between lumbar nerve root and lamina. Methods Twelve formalin soaked adult male cases （24 sides） were checked. The starting point from lumbar nerve root to the back midline, to the corresponding lamina up and down edges, and to the angle of the back midline were measured. Results The distance from starting point of L1 and L5 nerve root to the back midline were 12.6 ± 2. lmm and 8.8 ± 1. 1mm, respectively, which demonstrated that the decreasing trend from L1 to L5. The distance from starting point of L1 and L5 nerve root to the corresponding lamina up and down edges were 14.7 ± 0.3. l mm and 22.3 ± 5.0mm, respectively, which showed that the increasing trend from L1 to L5. The starting point of never root from L1 to L3 were in the middle of the corresponding lamina with decreased distance from the upper edge. The starting point of never root from L4 and L5 were in the up of the corresponding lamina with increased distance from the upper edge. Conclusion Anatomic variations can be observed from the starting point of never root to the corresponding lamina.
