【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(P0.05),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(P0.05)。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。
[Abstract]:The length of the long bone and its metaphyseal structure were measured in 51 fetuses with prenatal examination. The length of the long bone and its metaphyseal structure was calculated. The length of the long bone was measured by X-ray radiography of cadaveric cadavers after induced labor. The length of bare bone (including metaphyseal structure) was measured. All bare bones were taken X-ray and the length of naked bone was measured. The morphological and structural characteristics of the long bone were observed in water. The bone diaphysis and length of the long bone measured by ultrasound were compared with the X-ray measurements of the cadaveric bone. The difference was statistically significant (P 0.05), the X-ray value of cadaveric long bone was larger than that of long bone shaft measured by ultrasound, and the length of bare bone was smaller than that of long bone, and the total length of long bone measured by ultrasound was compared with that of bare bone. The length of long bone and the sum of metaphyseal structure were equal to the length of bare bone. The length of cadaveric X-ray could not completely reflect the total length of long bone. The total length of the diaphysis and metaphyseal structure is close to the length of the bare bone, which can reflect the development of fetal long bone more truthfully, so it is helpful to evaluate the fetal intrauterine growth retardation and short bone more accurately.
