摘要

背景:一些研究已经证实了胸骨的解剖变异。由于剑突作为各种腹肌锚的核心作用,我们研究了剑突长度与男性和女性体质指数之间可能的相关性。方法:在心脏手术中胸骨正中切开术前测量胸骨长度。体表面积(BSA)由身高和体重计算,采用标准表格。长度小于等于1cm的剑突被认为是退化的。结果:男性剑突明显变长。男性剑突长度与患者身高、BSA呈显著正相关,女性剑突长度与患者身高、BSA呈显著正相关。剑突退化在女性中更为常见。结论:我们的研究结果表明剑突形态存在明显的性别差异,仅在雄性中呈现比例比例。在女性中这种鳞片的缺失暗示了剑突退化背后的另一种机制。

Xiphoid Size and Gender Differences: An Anatomical Study
Background: Several studies have documented anatomical variations of the sternum. Because of its central role as an anchor of various abdominal muscles we have investigated a possible correlation between xiphoid length and body habitus indices, in both males and females. Method: Measurements of sternal length were obtained prior to median sternotomy during cardiac surgery. Body Surface Area (BSA) was calculated from height and weight, using standard tables. A xiphoid 1cm or less in length was considered vestigial. Results: The xiphoid was significantly longer in males. There was a positive significant correlation between xiphoid length and patient height and BSA in males, but not in females. Vestigial xiphoid was significantly commoner in females. Conclusion: Our results demonstrate a marked gender difference in xiphoid morphology, with proportional scaling only exhibited in males. The absence of this scaling in females suggests an alternative mechanism behind vestigial xiphoid.
