Fetal extremities were examined in 300 pregnant women between 16th and 24th week of gestation by real-time ultrasound. The limb bones of femur, humerus, tibia-fibula and radius-ulna complexes were measured and correlated to menstrual age and estimated age by ultrasound. The standard curves for limb bone growth show a linear increase with constant standard deviations. As fetal limb bone growth is close correlated to gestational age estimation of gestational age is exact as estimation from menstrual dates. Finding out skeletal malformations can be done very effective in patients of high risk.
在妊娠16至24周期间，对300名孕妇进行了实时超声检查以观察胎儿四肢。测量了股骨、肱骨、胫腓骨和桡尺骨复合体的四肢骨骼，并将其与月经龄及超声估计龄进行关联。四肢骨骼生长的标准曲线呈线性增长且标准差恒定。由于胎儿四肢骨骼生长与胎龄密切相关，因此胎龄估计与根据月经日期的估计一样准确。在高危患者中，可以非常有效地发现骨骼畸形。
