研究设计：解剖测量目的：为了获得定量解剖数据的每个脊髓段在人类，并确定存在的相关性之间的措施，设置：康复医学科，釜山国立大学医院，釜山，韩国。方法：共15防腐韩国成年人尸体（13名男性，两名女性，平均年龄57.3岁）。每个脐带段的长度被定义为根部附着长度加上上部根间长度。在进行全椎体切除术后，在C3-S5节段的近端和远端点进行横向切割。结果：横径以C5段最大，T8段逐渐减小，T5段最小，T8段最大，T8段最小。但各节段矢状径随节段变化不明显。颈椎和腰椎的扩大由节段的横径决定。C5节段的横截面积最大，为75.0 mm（2）。T6节段最长，平均长度为22.4 mm。颈髓中最长的节段为C5节段（15.5 mm），腰髓中最长的节段为L1节段。C5节段的体积最大，值为1173.9 mm（3）。结论：我们发现在胸段脊髓中测量的参数值与在颈段和腰段或腰骶段脊髓中测量的参数值相比存在特征性的定量差异。脊髓节段的这些测量似乎提供了有价值的和实用的标准定量特征，并可能提供基本数据，了解有关的病理生理条件的脊髓的形态特征。
Study design: Anatomical measurement.Objective: To obtain quantitative anatomical data on each spinal cord segment in human, and determine the presence of correlations between the measures.Setting: Department of Rehabilitation Medicine, Pusan National University Hospital, Pusan, Korea.Methods: A total of 15 embalmed Korean adult human cadavers ( 13 males, two females; mean age 57.3 years) were used. The length of each cord segment was defined as the root attachment length plus the upper inter-root length. After performing a total vertebrectomy, a transverse cut was made at the approximate proximal and distal point of each segment from segment C3 to S5. Sagittal and transverse diameters at the proximal end of each segment, and cross-sectional area, height, and volume of the segment were measured.Results: The transverse diameter was largest at segment C5, and decreased progressively to segment T8. However, the sagittal diameter of each segment did not change distinctly with the segment. The cervical and lumbar enlargements were determined by the transverse diameters of the segments. Segment C5 had the largest cross-sectional area, at 75.0 mm(2). Segment T6 was the longest, averaging 22.4 mm in length. The longest segment in the cervical spinal cord was segment C5, at 15.5 mm, and segment L1 in the lumbar spinal cord. The volume was largest at segment C5, with a value of 1173.9 mm(3).Conclusions: We found characteristic quantitative differences in the values of the parameters measured in the thoracic spinal cord compared to those measured in the cervical and lumbar or lumbosacral spinal cords. These measurements of spinal cord segments appear to provide valuable and practical standard quantitative features and may provide basic data for understanding the morphometric characteristics relevant to pathophysiologic conditions of the spinal cord.
