A prospective cross-sectional study of 515 singleton fetuses of ages between 15 and 42 weeks' gestation was performed. At gestational ages greater than 26 weeks, only fetuses with a sonographic estimated fetal weight between the 10th and 90th percentiles for growth were included. Scapular length (cm) as a function of gestational age (weeks) was expressed by the regression equation: SL = 0.3289 + 0.9553 (GA) with a Pearson correlation coefficient of R2 = 0.942. This study defines the normal limits of scapular length, demonstrates a high correlation between scapular length, gestational age, and other standard measurements of fetal growth, and indicates that scapular length can predict gestational age in fetuses with normal growth.
对515例孕龄在15至42周的单胎胎儿进行了一项前瞻性横断面研究。孕龄大于26周时，仅纳入超声估计胎儿体重处于生长第10至90百分位数之间的胎儿。肩胛长度（cm）作为孕龄（周）的函数，由回归方程表示：SL = 0.3289 + 0.9553（GA），Pearson相关系数R2 = 0.942。本研究确定了肩胛长度的正常范围，证明了肩胛长度、孕龄和胎儿生长的其他标准测量值之间存在高度相关性，并表明肩胛长度可预测生长正常胎儿的孕龄。
