【摘要】：[目的]通过应用解剖学方法探讨经皮颈椎后路内窥镜下颈椎间盘切除术的安全性因素,为临床手术提供理论依据。[方法]选取5具成人尸体标本,观测侧块高度(a)、宽度(b);以关节突关节间隙后内侧缘交点(O点)为中心,建立平面直角坐标系,观测O点与对应节段神经根下缘和硬脊膜外侧缘交点(A点)、下一节段神经根上缘与硬脊膜外侧缘交点(B点)的位置关系及各象限重要结构的毗邻关系;O点与硬脊膜外侧缘的水平距离(e)、与椎动脉前壁的垂直距离(g)以及内侧壁的水平距离(j);椎动脉内侧壁与硬脊膜外侧缘的水平距离(d);神经根与下关节突交点和硬脊膜外侧缘的水平距离(c);上位椎弓根内下缘(G点)与下位椎弓根内上缘(H点)连线与O点的水平距离(f);AB间的距离(k)。所得数据行统计学分析。[结果]a为(10.17±0.66)mm~(11.69±0.97)mm;b为(10.30±0.89)mm~(12.29±0.47)mm;e为(5.66±0.51)mm~(7.57±0.44)mm;g为(3.79±0.44)mm~(4.29±0.47)mm;d为(5.73±0.47)mm~(8.29±0.70)mm;c为(6.90±0.60)mm~(8.27±0.44)mm;f为(1.69±0.87)mm~(4.83±0.96)mm;j为(4.81±0.90)mm~(7.40±0.79)mm;k为(18.12±1.11)mm~(20.87±1.19)mm。[结论]PPECD中O点是更具临床意义的定位点,可作为手术入点标示开骨窗安全范围、准确定位病变部位并避免损伤椎管内外重要结构。
[Abstract]:[objective] to explore the safety factors of percutaneous endoscopic cervical discectomy by anatomical method, and to provide theoretical basis for clinical operation. [methods] five adult cadavers were selected. The height of the lateral mass, (a), width, (b); was observed, and the point of intersection of the posterior medial margin of the articular process space (O point) was taken as the center, and the plane coordinate system was established. The position relationship between O point and the lower edge of the corresponding segment nerve root and the lateral edge of the dural (point A), the intersection point (point B) between the upper edge of the next segment nerve root and the lateral edge of the dural membrane (point B) and the adjacent relationship between the important structures of each quadrant and the hard ridge were observed. Horizontal distance between (e), and anterior wall of vertebral artery (g) and horizontal distance between medial wall of vertebral artery (j);) and lateral side of vertebral artery (j);) the intersection of (d); nerve root with inferior articular process and lateral margin of dural dura The distance between the horizontal distance between the upper lower edge (G point) of the upper pedicle of (c); and the upper edge of the lower pedicle (H point) and the horizontal distance between O point and (f) point AB, (k). The data were analyzed statistically. [缁撴灉]a涓，
