一项前瞻性横断面研究通过超声检查了 530 名妊娠 13 至 42 周的患者的胎儿肢体骨骼的生长情况。所有病例均测量了股骨、胫骨、肱骨和桡骨的长度，393例测量了腓骨和尺骨的长度。计算妊娠每周的平均长度（±2标准差）。所有四肢骨在妊娠13周至25周期间均呈现线性生长，此后生长曲线呈现非线性。每个骨头的 BPD 和骨长度之间都存在很强的线性关系 (r > 0.98)。在五个流产的胎儿中，骨化骨干的产前超声测量结果与产后放射学测量结果（30 个肢体骨）进行了比较。发现了良好的一致性（超声和 X 射线测量之间的差异为 0.7 ± 0.5 [SD] mm 或 3.0 ± 2.4 [SD]%），表明超声对骨化骨干进行成像。
Growth of fetal limb bones has been examined in a prospective cross‐sectional study in 530 patients between 13 and 42 weeks of gestation by ultrasound. The length of the femur, tibia, humerus, and radius were measured in all cases, and fibula and ulna in 393 cases. For each week of gestation mean lengths (± 2 standard deviations) were calculated. All limb bones showed linear growth from 13 weeks to 25 weeks of gestation, after which the growth curve appeared nonlinear. A strong linear relationship (r > 0.98) between the BPD and bone length was found for each bone. In five aborted fetuses, prenatal sonographic measurements of the ossified diaphyses were compared with the postnatal radiologic measurement (30 limb bones). A good agreement was found (difference between ultrasound and X‐ray measurements 0.7 ± 0.5 [SD] mm or 3.0 ± 2.4 [SD]%), indicating that ultrasound images the ossified diaphysis.
