【摘要】：[目的]通過(guò)應(yīng)用解剖學(xué)方法探討經(jīng)皮頸椎后路內(nèi)窺鏡下頸椎間盤(pán)切除術(shù)的安全性因素,為臨床手術(shù)提供理論依據(jù)。[方法]選取5具成人尸體標(biāo)本,觀測(cè)側(cè)塊高度(a)、寬度(b);以關(guān)節(jié)突關(guān)節(jié)間隙后內(nèi)側(cè)緣交點(diǎn)(O點(diǎn))為中心,建立平面直角坐標(biāo)系,觀測(cè)O點(diǎn)與對(duì)應(yīng)節(jié)段神經(jīng)根下緣和硬脊膜外側(cè)緣交點(diǎn)(A點(diǎn))、下一節(jié)段神經(jīng)根上緣與硬脊膜外側(cè)緣交點(diǎn)(B點(diǎn))的位置關(guān)系及各象限重要結(jié)構(gòu)的毗鄰關(guān)系;O點(diǎn)與硬脊膜外側(cè)緣的水平距離(e)、與椎動(dòng)脈前壁的垂直距離(g)以及內(nèi)側(cè)壁的水平距離(j);椎動(dòng)脈內(nèi)側(cè)壁與硬脊膜外側(cè)緣的水平距離(d);神經(jīng)根與下關(guān)節(jié)突交點(diǎn)和硬脊膜外側(cè)緣的水平距離(c);上位椎弓根內(nèi)下緣(G點(diǎn))與下位椎弓根內(nèi)上緣(H點(diǎn))連線與O點(diǎn)的水平距離(f);AB間的距離(k)。所得數(shù)據(jù)行統(tǒng)計(jì)學(xué)分析。[結(jié)果]a為(10.17±0.66)mm~(11.69±0.97)mm;b為(10.30±0.89)mm~(12.29±0.47)mm;e為(5.66±0.51)mm~(7.57±0.44)mm;g為(3.79±0.44)mm~(4.29±0.47)mm;d為(5.73±0.47)mm~(8.29±0.70)mm;c為(6.90±0.60)mm~(8.27±0.44)mm;f為(1.69±0.87)mm~(4.83±0.96)mm;j為(4.81±0.90)mm~(7.40±0.79)mm;k為(18.12±1.11)mm~(20.87±1.19)mm。[結(jié)論]PPECD中O點(diǎn)是更具臨床意義的定位點(diǎn),可作為手術(shù)入點(diǎn)標(biāo)示開(kāi)骨窗安全范圍、準(zhǔn)確定位病變部位并避免損傷椎管內(nèi)外重要結(jié)構(gòu)。
[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. [緇撴灉]a涓，
