摘要
目的 :建立正常椎间盘与相应椎管及内容物相互关系的解剖数据。方法 :选用 43例尸体颈椎进行CT、MRI扫描 ,自蛛网膜下腔注入铸型造影剂后制作横断层标本并行X线轴位摄影。结果 :第 4至 7颈椎的椎管矢径与椎间盘矢径之比分别为 82 .42± 10 .10、80 .44± 9.0 7、81.83± 7.0 4% ,硬膜囊矢径与椎间盘矢径之比分别为 6 2 .6 6± 8.12、5 3 .46± 2 4.3 4、70 .5 8± 11.3 1% ,硬膜囊矢径与椎管矢径之比分别为76 .47± 11.5 6、79.10± 9.3 9、77.85± 6 .84% ,椎管面积与椎间盘面积之比分别为 96 .12± 10 .3 0、80 .87±10 .96、72 .73± 10 .40 % ,标本的解剖学与影像学各测量结果经统计学处理无显著性差异 (P >0 .0 5 )。结论 :本文从实验材料到方法接近于临床对活体的测量结果 。
To obtain the anatomy data of the cervical intervertebral discs,vertebral canal and its contents.Methods:In present study,43 cervical vertebral of adult specimens were examined on CT and MRI scanning instrument.With a kink of casting mould contrast medium injected into subarachnoid space,the cross sectional specimens were manufactured and measured on the axis radiogram.Results:The ratio of vertebral canal sagittal diameter to intervertebral disc sagittal diameter from C 4～5 to C 6～7 are 82.42±10.10,80.44±9.70 and 81.33±7.04% respectively.That of dural capsule sagittal diameter to interverteral disc sagittal diameter are 62.66±8.12,53.46± 24.34 and 70.58±11.31%.That of dural capsule sagittal diameter to intervertebral canal sagittal diameter are 76.47± 11.56 ,79.10±9.39 and 77.85± 6.84% .That of vertebral canal area to intervertebral disc area are 96.12±10.30,80.87±10.96 and 72.73±10.40% separately.There are no significant different between the anatomic measurements and image results.Conclusions:Because the material and methods involoved in this study are nearly same as those in clinical exa mination,the result could be regarding as a normal anatomic data standard for the youth.
