To determine the value of prenatal ultrasonographic scapula measurements for fetal growth and development as an adjunct to assessing in utero development, a prospective study of ultrasonography was conducted in 343 pregnant women with uneventful pregnancies with gestational ages from 16 to 41 weeks, and several biometric measurements were obtained. The relationships of scapula length with gestational age and with biparietal diameter, femur length, abdominal circumference and scapula length were examined. With the ultrasonographic examinations of 343 healthy pregnant women, a nomogram of scapula length measurements estimating gestational age and predicting the biparietal diameter, abdominal circumference, and femur length was generated. Linear relationships were found between the scapula length and the gestational age (R2 = 0.94, p < 0.0001), the biparietal diameter (R2 = 0.94, p < 0.0001), abdominal circumference (R2 = 0.94, p < 0.0001), and the femur length (R2 = 0.95, p < 0.0001). The rate of increase of scapula length was significantly higher before 28 weeks of gestation than in later pregnancy (p < 0.0001). The correlation coefficients between gestational age and scapula length were 0.95 before 28 weeks of gestation and 0.86 in later weeks. These results suggest that scapula length measurement is a valuable parameter for the assessment of fetal growth and development.
为了确定产前超声测量肩胛骨对评估胎儿生长发育的价值，作为评估子宫内发育的辅助手段，对343例妊娠过程顺利、孕周为16至41周的孕妇进行了超声前瞻性研究，并获得了多项生物测量数据。研究了肩胛骨长度与孕周、双顶径、股骨长度、腹围以及肩胛骨长度之间的关系。通过对343例健康孕妇的超声检查，绘制了一张估计孕周并预测双顶径、腹围和股骨长度的肩胛骨长度测量列线图。发现肩胛骨长度与孕周（R2 = 0.94，p < 0.0001）、双顶径（R2 = 0.94，p < 0.0001）、腹围（R2 = 0.94，p < 0.0001）和股骨长度（R2 = 0.95，p < 0.0001）之间存在线性关系。妊娠28周前肩胛骨长度的增加速率显著高于妊娠后期（p < 0.0001）。妊娠28周前孕周与肩胛骨长度的相关系数为0.95，后期为0.86。这些结果表明，肩胛骨长度测量是评估胎儿生长发育的一个有价值的参数。
