摘要：

背景：近年来的研究表明人体的许多器官、组织等都存在着明显的性别差异，骨及骨内的神经生长等也存在性别差异，且骨科及其他学科的一些精细手术如膝关节的假体置换，肘关节的骨折治疗等都要考虑到性别差异的影响。
目的：比较国人腰椎椎体的性别差异。
方法：收集中山大学第二附属医院磁共振室行腰椎磁共振检查资料齐全的正常成年人67名，其中男35名，年龄20~51(39.4±4.3)岁；女32名，年龄19~52(41.2±5.6)岁。T2加权像横轴位测量比较成年男，女腰椎椎体的面积S；正中矢状位测量椎体的上矢状径Dn，中矢状径Dm，下矢状径Dd，前高Ha，中高Hm，后高Hp；然后根据测量结果推算椎体的高度比：前高比Ha/Dm，中高比Hm/Dm，后高比Hp/Hm。
结果与结论：国人男女椎体的性别差异显著，从L1~L5，椎体面积逐渐升高，男性椎体面积始终大于女性；男性椎体的矢状径Dn，Dm，Dd总大于女性，男性椎体的高度Ha，Hm，Hd大于女性；但是女性椎体的前高比Ha/Dm，中高比Hm/Dm，后高比Hp/Hm总大于男性。

Abstract:

BACKGROUND: Recent studies have shown that there are gender differences in many organs and tissues, as well as bone and nerve growth in the bone of human body. Moreover, gender differences may exist in some operations, such as knee joint replacement and elbow fracture treatment.
OBJECTIVE: To explore the gender differences in lumbar vertebral body.
METHODS: A total of 67 normal adults, comprising 35 males aged 20-51(39.4±4.3) years, and 32 females aged 19-52(41.2±5.6) years. Morphometric analysis was performed on T2-weighted midsagittal and transverse digital images. For each vertebral level between L1 to L5, the superior sagittal diameter Dn, the middle sagittal diameter Dm, the inferior sagittal diameter Dd, the anterior height Ha, central height Hc, and posterior height Hp were measured from the sagittal images of the lumbar spine. Three new height ratios of vertebral body shape were derived from these measurements: anterior height ratio (Ha/Dm), middle height ratio (Hm/Dm) and posterior height ratio (Hp/Dm). The areas of lumbar vertebral bodies were measured from the superior transverse images of every vertebral body.
RESULTS AND CONCLUSION: The gender differences were significant: From L1 to L5, the area (S), the Dn, Dm, Dd, Ha, Hm, and Hp of male vertebral body was respectively greater than the female’s. But the Ha/Dm, Hm/Dm, Hp/Dm of female vertebral body was greater than the male’s.
