摘要

前言:骶骨裂孔是介入临床手术的重要入口。骶骨裂孔的识别通常很容易,但有时会变得困难,特别是对于肥胖的人。本研究的目的是确定额外的解剖标志,以提高经骶裂孔手术的成功率。方法:对31例未损伤成人骶骨进行形态计量学研究。测量是借助游标卡尺和测角仪完成的。结果:髂后上棘作用于骶外侧嵴上部(上外侧嵴)。以两个上外侧嵴之间的距离为基底,以两个上外侧嵴到骶裂孔顶点的距离为三角形的两条边。三角形的基底、右侧、左侧分别为65.81 mm±4.00mm、66.74 mm±6.18 mm、66.84mm±6.07m。骶管裂孔顶端平均深度(AP直径)为4.17 mm±1.18 mm。另一个重要的标志是骶角至骶2孔水平的平均距离为59.23mm±4.77mm。结论:骶骨裂孔的两个上外侧嵴与裂孔顶端形成的三角形在大部分骶骨内为等边三角形,这是经骶裂孔手术中骶骨尖定位的重要参数。大多数标本的骶管顶端AP直径足以通过针和内窥镜。

Morphometric Study of Sacral Hiatus with Significance in Interventional Clinical Procedure
Introduction: The sacral hiatus is an important portal for interventional clinical procedure. Identification of sacral hiatus is usually easy but sometime it becomes difficult particularly in obese person. Aim of present study was to identify additional anatomical landmarks to increase the success rate of trans-sacral hiatal procedure. Methodology: The morphometric study was conducted on 31undamaged adult sacra. The measurements were done with the help of Vernier caliper and goniometer. Results : The posterior superior iliac spines impose upon upper part of lateral sacral crest (superolateral crest). The distance between two superolateral crests was considered as the base and distance from two superolateral crests to apex of sacral hiatus as two sides of the triangle. The base, right side and left side of the triangle were 65.81 mm ± 4.00mm, 66.74 mm ± 6.18 mm and 66.84mm ± 6.07m respectively. The mean depth (AP diameter) of sacral canal at the apex of sacral hiatus was 4.17 mm ± 1.18 mm. An additional important landmark, the mean distance from the level of sacral cornua to the level of S2 foramina was 59.23mm ± 4.77mm. Conclusion: The triangle formed by the two superolateral crests and apex of the sacral hiatus was an equilateral triangle in most of the sacra and this is very important parameter in localization of sacral apex in transacral hiatal procedures. The AP diameter of sacral canal at the apex was adequate for passage of needle and endoscope in most of the specimens.
