To assess the length of the spinal cord relative to the vertebral column during fetal development, we performed translumbar myelograms on 340 spontaneously aborted fetuses. Of these, 146 were selected for study. There were 76 males and 70 females, with fetal age ranging from 7 to 33 weeks. Significant variation in the level of spinal cord termination was found in fetuses between 12 and 25 weeks gestational age. In fetuses between 25 and 33 weeks gestational age, the cord ended at or above the third lumbar vertebra.
为评估胎儿发育过程中脊髓相对于脊柱的长度，我们对340例自然流产胎儿进行了经腰段脊髓造影。其中，146例被选入研究。有76例男性和70例女性，胎龄范围为7至33周。在孕龄12至25周的胎儿中发现脊髓终止水平存在显著差异。在孕龄25至33周的胎儿中，脊髓在第三腰椎或以上水平终止。
