【摘要】：目的建立孕20~26周胎儿内踝角正常参考值范围,探讨内踝角在诊断马蹄内翻足中的价值。方法将孕20~26周产前超声筛查中可疑马蹄内翻足的42只胎足(共27胎)作为病例组,另随机选取20~26周产前超声筛查正常足300只(共150胎)作为正常对照组,分别测量两组胎儿第一、五跖骨横切面足底连线与胫骨长轴夹角(即内踝角)大小,对两组数据进行直线相关分析。结果正常胎儿内踝角各孕周测量值恒定,与孕周变化无显著相关性(P0.05),(喁±s)为(78.89°±9.24°),病例组(喁±s)为(37.64°±7.93°),与正常对照组相比,内踝角测量值差异具有统计学意义(P0.01)。结论正常胎儿内踝角的角度与孕周变化无显著相关性,测量值可为产前诊断马蹄内翻足提供较准确的诊断信息,具有较高的临床应用价值。
[Abstract]:Objective to study the value of medial malleolus angle in the diagnosis of horseshoe varus foot. Methods 42 cases of suspected equinovarus feet (27 fetuses) were selected as the case group, and 300 normal feet (150 fetuses) were randomly selected as the control group. The angle between the first and fifth metatarsal plantar line and the long axis of tibia (medial malleolus angle) was measured, and the linear correlation analysis was carried out between the two groups. Results the measured values of the medial malleolus angle of normal fetuses were constant and had no significant correlation with the changes of gestational weeks (P = 78.89 掳卤9.24 掳) and those of the case group (word 卤s) were 37.64 掳卤7.93 掳. Compared with the normal control group, there was a significant difference in the measurement value of the medial malleolus angle (P 0.01). Conclusion there is no significant correlation between the angle of the medial malleolus angle of the normal fetus and the change of gestational weeks. The measured values can provide accurate diagnostic information for the prenatal diagnosis of horseshoe varus pedis and have high clinical application value.
