摘　　要：51例经产前检查长骨符合孕龄的胎儿,宫内测量长骨骨干及其干骺端结构的长度,计算总长度,引产后做尸体X线摄片测量长骨长度,并测量其裸骨长度(包括干骺端结构),所有裸骨均做X线摄片并测量裸骨X线长度,将几种测量结果做统计学分析。部分引产儿及部分新鲜裸骨分别置于水中观察长骨形态结构特征。超声测量长骨骨干值及裸骨长度分别与尸体长骨X线测值比较,差异均有统计学意义(P<0.05),尸体长骨X线测值大于超声测量长骨骨干值,小于裸骨长度;将超声测量长骨总长度与裸骨长度比较,差异无统计学意义(P>0.05)。超声测量胎儿长骨骨干长度及干骺端结构之和相当于裸骨长度,尸体X线长度不能完全反映长骨总长度,而超声测量骨干及其干骺端结构的总长度接近于裸骨长度,可更真实地反映胎儿长骨发育情况,从而有助于更准确地评价胎儿宫内发育迟缓及短长骨。51 fetuses with normal long bones（ including diaphyses and epimetaphyseal） in prenatal ultrasonic scans performed at 20 ~ 37 weeks of gestation were retrospectively reviewed. The data collected included the prenatal length of long bones（ mainly including femoral and humeral） measured by ultrasonic scans,the prenatal length of diaphyses measured by ultrasonic scans,the postnatal length measured by X-ray after abortion,the actual length of the bare bones after autopsy,the length of the bare bones measured by X-ray after autopsy. These results were analyed statistically. Meanwhile,the form of part fetuses,bodies and bare bones placed in water were observed. The prenatal length of diaphyses measured by ultrasonic scans was significantly lower than the postnatal length measured by X-ray after abortion（ P〈0. 05） and the actual length of the bare bones was significantly higher than the postnatal length measured by X-ray after abortion（ P〈0. 05）. Compared with the prenatal total length of long bones measured by ultrasonic scans,the actual length of the bare bones was not significantly different（ P〉0. 05）. The length of long bones measured by ultrasonic scans can more realistically reflect prenatal length of the actual long bones and contribute to a more accurate assessment of fetal intrauterine growth retardation and fetal shortened long bone deformity.
