Intrauterine growth retardation (IUGR) is associated with an increase in perinatal mortality as well as long-term neurobehavioral morbidity. Despite the increasing sophistication of antenatal fetal assessment, the diagnosis of growth retardation remains difficult. Since the fetal effects of growth inhibition are variable, no one ultrasonic parameter can diagnose with certainty the growth-retarded fetus. The reduction of thigh circumference with IUGR is secondary to the muscle wasting that is characteristic of this disease process. The sensitivity (77.8%) and specificity (75%) of thigh circumference may make it a useful additional sonographic parameter in the evaluation of fetal growth retardation.
宫内生长受限（IUGR）与围产期死亡率增加以及长期神经行为疾病相关。尽管产前胎儿评估日益复杂，但生长受限的诊断仍然困难。由于生长抑制对胎儿的影响各不相同，没有一个超声参数能够确定诊断生长受限胎儿。IUGR时大腿围减小是该病特征性肌肉萎缩的继发表现。大腿围的敏感性（77.8%）和特异性（75%）可能使其成为评估胎儿生长受限的一个有用的附加超声参数。
