随着B超仪性能的不断改进,扫描技术的日益提高,对于胎儿骨骼的观测愈来愈细致,应用长骨测量观测胎儿宫内生长发育及早期诊断骨骼畸形,在国外已广泛开展,但在国内,对于肱骨、胫骨、尺骨测量报告甚少,我们对256例正常单胎胎儿进行长骨测量,旨在建立本地区胎儿各长骨的周增长率及正常生长发育曲线,作为予测胎龄,监测胎儿宫内生长发育及诊断骨骼畸形的依据。1 材料和方法1.1 研究对象 为256例单胎、妊娠16～41周之正常胎儿,除按末次月经计算胎龄外,并用B超测定双顶径进行核对,二者符合者列入本研究范围。
With the continuous improvement of B-meter performance, scanning technology is increasing, more and more detailed observation of fetal bones, the application of long bones to observe intrauterine growth and development and early diagnosis of skeletal deformities has been widely carried out in foreign countries, but in the country , There is little report on humerus, tibia and ulna. We measured long bones of 256 normal singleton fetuses to establish the weekly growth rate and normal growth and development curve of the long bones of the fetus. Intrauterine growth and development and diagnosis of skeletal deformity basis. 1 Materials and Methods 1.1 The study of 256 singleton fetuses, normal fetus of 16 to 41 weeks of gestation, in addition to calculating the gestational age by the last menstrual period, and B-measured biparietal diameter for verification, the two were included in the scope of this study .
