椎管内手术恢复截瘫后膀胱控制功能的应用解剖

Applied anatomy of operation in vertebral canal to restore urocystic control function after paraplegia

目的 :为恢复截瘫病人膀胱控制功能的椎管内手术提供解剖学依据。方法 :在 10例 (男 3 ,女 7)成人脊柱标本上 ,暴露T11节段以下全部脊髓 ,对各神经根进行观测。结果 :全部L2 ～S1神经根与S2神经根呈重叠关系 ;3例男性和 2例女性L1神经根与S2 神经根与S2 神经根呈重叠关系。除 1例男性的T12 神经根和S2 神经根有重叠外 ,其余全部T12 和T11神经根之间有距离 ,分别为 2 9.1mm和 5 2 .6mm。结论 :椎管内S2 神经根与上位神经根直接吻接 ,在男性最高多数可达L1神经根 ,在女性可达L2 神经根 ;少数(1例 )男性可提高至T12 神经根 ,少数 (2例 )女性可提高至L1神经根。

Objective: To provide anatomical basis for operation in vertebral canal to restore urocystic control function after paraplegia.Methods: Spinal cords under T 11 segment were exposed and each nerve roots were observed on 10 adult spinal specimens (3male, 7female).Results: L 2～S 1 nerve roots overlaped with S 2 on all specimens, and L 1 nerve root overlaped with S 2 on all male and 2 female specimens.There exist 29.1 mm and 52.5 mm distance between the T 12 , T 11 nerve roots and S 2 nerve root on all specimens except for one male, whose T 12 nerve root overlaped with S 2.Conclusion: In vertebral canal, the highest superior nerve root that S 2 could be anastomosed with directly is L 1 in male and L 2 in female, and it is T 2 in 1 male and L 1 in 2 female in this study.
