The relationship of thoracic spine length and birth weight was evaluated in newborn infants of 26-41 weeks gestational age, and standards of thoracic spine length were established. Thoracic spine length is an accurate index of trunk length in the: if the gestational age is known, a markedly lengthened thoracic spine suggests that the mother is diabetic, while a markedly shortened thoracic spine suggest retarded intrauterine growth.
对孕龄26至41周的新生儿评估了胸椎长度与出生体重的关系，并建立了胸椎长度标准。胸椎长度是躯干长度的一个准确指标：如果已知孕龄，胸椎明显延长提示母亲患有糖尿病，而胸椎明显缩短提示宫内生长迟缓。
