摘要
目的:为研究胎儿骨骼系统发育规律,探讨1种能准确测量胚胎弯曲骨弧长度的新方法。方法:利用微积分推导出测量公式,将已测得的弯曲骨的弦长和曲高数据代人公式,计算得到弯曲骨弧长度。分别对胎儿顶骨冠状弧长度及50例成人顶骨弧长进行测量,与传统手工测量方法进行比较。结果:该方法与手工测量差异无统计学意义。结论:本研究解决了弯曲扁骨弧长度的测量难题。方法简便准确,可用于弯曲度小于180。胎儿扁骨中任一弯曲骨的骨化长度的测量及人体其他部位弯曲骨弧长度的测量。
Objective: To develop a novel method to precisely measure the arc length of curving bone in human embryo. Methods ~ We developed a formula by using differential equation and the arc length of bending bones was calculated according to the chord length and height. We measured the coronal arc length of parietal bones in fetus and measured the parietal arc and coronal arc length of fifty embryos. Results: Our results showed that the arc length calculated using the formula was not significantly different from that obtained by manual measurements. Conclusion: This method was simple and precise, and can be used to measure the ossification length of any fetus parietal bones with less than 180° curvature or the arc length of bones in the other parts of human.
