The clinical applicability and usefulness of nine ratios that express the relation between particular fetal growth parameters were tested in ten fetuses affected by skeletal dysplasia. The results were compared with the ratios calculated from five growth-retarded fetuses without structural anomalies. Femur/foot, femur/head circumference, head circumference/thoracic circumference and abdominal circumference/thoracic circumference ratios are useful additional parameters for the prenatal ultrasonographic diagnosis of skeletal dysplasias. They reduce the problem of an unknown gestational age and help to distinguish between fetal skeletal dysplasia and intra-uterine growth-retardation caused by other factors.
在10例患有骨骼发育异常的胎儿中测试了9种表达特定胎儿生长参数之间关系的比率的临床适用性和实用性。将结果与从5例无结构异常的生长受限胎儿计算得出的比率进行比较。股骨/足、股骨/头围、头围/胸围和腹围/胸围比率是产前超声诊断骨骼发育异常的有用附加参数。它们减少了孕周未知的问题，并有助于区分胎儿骨骼发育异常和由其他因素引起的宫内生长迟缓。
