Sonograms and radiographs of the lumbar spine in 51 fetuses and neonates with thanatophoric dwarfism, achondroplasia, and osteogenesis imperfecta type II were retrospectively evaluated. Study data included 27 prenatal and 27 neonatal sonograms and radiographs in 40 fetuses and neonates and 11 cases described in the radiology literature. To precisely compare the sonographic and radiographic appearances of platyspondyly in dysplasia, a simple vertebral ratio was obtained from measurement of vertebral interspace and vertebral body height. Normal ranges were obtained from sonograms in 125 normal fetuses and from radiographs in 55 normal fetuses. The severe platyspondyly of thanatophoric dysplasia and the milder platyspondyly of achondroplasia were detected by about 20 menstrual weeks. The vertebral bodies appeared slightly larger on sonograms than on radiographs in both normal fetuses and fetuses with dysplasia.
对51例患有致死性侏儒症、软骨发育不全和II型成骨不全的胎儿及新生儿的腰椎超声图像和X线片进行了回顾性评估。研究数据包括40例胎儿及新生儿的27份产前和27份新生儿超声图像及X线片，以及放射学文献中描述的11例病例。为了精确比较发育异常中扁平椎的超声和X线表现，通过测量椎间隙和椎体高度获得了一个简单的椎体比率。正常范围来自125例正常胎儿的超声图像和55例正常胎儿的X线片。致死性发育异常的严重扁平椎和软骨发育不全的较轻扁平椎在约孕20周时被检测到。在正常胎儿和发育异常的胎儿中，超声图像上的椎体看起来都比X线片上的略大。
