研究设计.本研究利用干燥颈椎和尸体颈椎标本对颈神经沟和椎间孔进行了研究。测量颈神经沟的8个线性尺寸和1个角度尺寸以及椎间孔的2个线性直径。背景资料总结。颈椎的解剖学研究很多，但关于颈神经沟的定量数据报道很少。本研究从41个完整的椎骨组（205个椎骨）和14个尸体颈椎中获得干燥的颈椎，C3-C7。干标本主要观察颈神经沟，尸体标本主要观察椎间孔。双侧进行了10次线性测量和1次角度测量。计算所有标本及男女标本的平均值、极差、酸标准差。男性和女性样本的尺寸差异不具有统计学显著性。从C3到C7，男性和女性标本的中间带的平均长度和椎体中线到中间带前缘的距离一致地增加。男女标本C3内侧带宽度均大于C4、C5和C6。所有节段的最小宽度范围为1-2 mm。内侧区深度从C3（男性3.2 mm，女性2.3 mm）逐渐增加至C7（4.9 mm）。男性样本为4.4 mm，女性样本为4.4 mm）。外侧柱后中点至神经沟后缘的前后距离以C7最小（男6.7mm，女6.1mm）。除C2-C3外，椎间孔的高度和宽度从头侧到尾侧均呈增加的趋势。这些数据可以加强对颈椎神经和根穿过颈神经沟和椎间孔时与其相关的重要骨元素的理解。
Study Design. The present study evaluated the cervical nerve groove and intervertebral foramen using dried vertebrae and cadaveric cervical spine.Objectives. To measure the cervical nerve groove in eight linear and one angular dimensions and the intervertebral foramen in two linear diameters.Summary of Background Data. Several anatomic studies of the cervical spine exist, but very little quantitative data have been reported on the cervical nerve groove.Methods. Dried cervical vertebrae, C3-C7, from 41 complete vertebral sets (205 vertebrae) and 14 cadaveric cervical spine were obtained for the present study. Anatomic evaluation focused on the cervical nerve groove for dry specimens and intervertebral foramen for cadaveric specimens. Ten linear and one angular measurements were made bilaterally. The mean, range, acid standard deviation were calculated for all of the specimens and for male and female specimens separately.Results. Differences in dimensions of malo and female specimens were not found to be statistically significant. The average lengths of tho medial zone and distances from-the midline of the vertebral body to the anterior border of the medial zone for male and female specimens consistently increased from C3 to C7. The width of the medial zone was larger in C3 than that of C4, C5, and C6 in male and female specimens. The minimum width for all levels ranged 1-2 mm. The medial zone depths gradually increased from C3 (3.2 mm for male and 2.3 mm for female specimens) to C7 (4.9. mm for male and 4.4 mm for female specimens). The smallest anteroposterior distances from the posterior midpoint of the lateral masts to the posterior border of the nerve groove were found in C7 (6.7 mm for male and 6.1 mm for female specimens). The general trend of the foraminal height and width increased from the cephalad:to caudal except at C2-C3.Conclusions. These data may enhance understanding of the important bony elements associated with the cervical spinal nerves and roots as they pass through the cervical nerve groove and the intervertebral foramen.
