文题释义:
三角工作区:最早由Kambin于1987年提出。由硬膜囊外侧缘、硬膜囊发出的神经根、下一椎体上缘构成的直角三角形区域。除L5-S1椎体间外该区域表面无骨性结构阻挡,无重要神经和大血管通过的三角形区域,许多学者还称为安全三角区。
骶丛:由腰骶干(L45)以及全部骶神经和尾神经的前支组成。骶丛位于盆腔内,在骶骨及梨状肌前面,髂内动脉的后方。骶丛分支分布于盆壁、臀部、会阴、股后部、小腿以及足肌和皮肤。骶丛除直接发出许多短小的肌支支配梨状肌、闭孔内肌、股方肌等外,还发出以下分支。
 
摘要
背景:目前腰骶丛三角工作区的概念比较混乱,需要通过实体解剖探索其实际的解剖范围界定和面积来指导临床实践。
目的:测量不同定义的腰骶丛三角工作区解剖范围界定和面积大小,为腰椎间盘微创技术安全性提供解剖学依据。
方法:解剖20具成人尸体标本的双侧腰骶丛,显露腰神经前支、关节突与下椎体终板区域,每个椎体的双侧神经根都被解剖到远端的网状组织。测量双侧L3-S1椎体间上关节突外侧和硬膜囊外侧的三角工作区的底和高的长度,并计算三角工作区的面积。

结果与结论:①L3-S1椎体间上关节突外侧三角工作区的面积男性介于23.8-30.7 mm2,女性介于18.7 - 27.3 mm2;硬膜囊外侧三角工作区面积男性介于92.4-103.7 mm2,女性介于87.5-102.7 mm2;②结果说明,L3-S1椎体间上关节突外侧三角工作区的面积介于18.7-30.7 mm2,硬膜囊外侧三角工作区面积介于87.5-103.7 mm2,在此三角工作区内进行手术操作是安全的。

Abstract:

BACKGROUND: Conception of three-dimensional reconstruction of the lumbosacal plexus is confused, and actual physical anatomy is needed to confirm its range and area thus providing guidence for clinical pratice.

OBJECTIVE: To measu the range and area of three-dimensional reconstruction of the lumbosacal plexus using different definitions, thereby providing anatomical basis for minimally invasive technique of lumbar disc.
METHODS: Posterior dissections of the lumbosacral plexus were performed bilaterally on 20 embalmed adult cadavers. Particular attention was paid to dissect anterior branches of lumbar nerve, upper articular process and lower vertebrae. Bilateral nerve roots at each spinal level were identified, and dissected distally to expose the plexus. The length of bottom and height of three-dimensional reconstruction locating on the lateral upper articular process between L3-S1 and the lateral of dural sac were measured to calculate the area.
RESULTS AND CONCLUSION: (1) The area of three-dimensional reconstruction locating on the lateral upper articular process between L3-S1 ranged from 23.8 mm2 to 30.7 mm2 in males, and 18.7 mm2 to 27.3 mm2, respectively. The area of three-dimensional resconstruction locating on the lateral dural sac ranged from 92.4mm2 to 103.7 mm2, and 87.5 mm2 to 102.7mm2, respectively. (2) In conclusion, the area of three-dimensional reconstruction locating on the lateral upper articular process between L3-S1 and dural sac covers from 18.7 mm2 to 30.7 mm2, and from 87.5 to 103.7 mm2, respectively, so operating in this triangle is safe.
