The computed tomography (CT) scans of 100 adult Chinese patients 18-60 years of age were studied to provide osteometric data on the Asian lumbar spine. The study population was composed of 63 men and 37 women. A total of 29 parameters were measured from each vertebral level. All the data were statistically analyzed for differences between men and women and left and right sides for paired structures. The data then were compared with data for white individuals where available. The results show that for Asians there is a significant sex difference (p < 0.001) for vertebral body and disk dimensions but not for the posterior elements or spinal canal. Compared with white individuals, Asians have a smaller vertebral body and a different spinal canal shape, with the lower part of the canal in relation to the vertebral body being narrowest. Such findings are of significance to the radiologist, to the surgeon, and in the design of instruments and implants for the Asian lumbar spine.
对100名年龄在18至60岁的中国成年患者进行了计算机断层扫描（CT），以获取亚洲人腰椎的骨测量数据。研究对象包括63名男性和37名女性。从每个椎体水平测量了总共29个参数。对所有数据进行了统计学分析，以比较男性和女性之间以及成对结构的左右两侧之间的差异。然后将这些数据与可获得的白人个体的数据进行比较。结果表明，对于亚洲人来说，椎体和椎间盘尺寸存在显著的性别差异（p < 0.001），但后部结构或椎管不存在性别差异。与白人个体相比，亚洲人的椎体较小，椎管形状不同，椎管下部相对于椎体最窄。这些发现对放射科医生、外科医生以及亚洲人腰椎器械和植入物的设计具有重要意义。
