【摘要】 目的　测定不同年龄正常儿童股骨颈颈前间隙的宽度 ,为儿童双侧髋关节疾病如双侧髋关节一过性滑膜炎的超声诊断提供正常参考值。方法　 14岁以下正常儿童按 1岁年龄间隔分成 14组 ,每组3 0例 ,共 42 0例 ,超声测定其双侧股骨颈颈前间隙的宽度 ,依次将各年龄组的均值以及同一年龄组双侧股骨颈颈前间隙的均值用t检验进行比较。结果　 14岁以下正常儿童股骨颈颈前间隙的均值为 2 .0～ 5 .9mm ,范围为 1.2～ 7.8mm。结论　不同年龄正常儿童股骨颈颈前间隙的宽度不同 ,14岁以下正常儿童股骨颈颈前间隙的均值 <6mm ,双侧差值 <1mm。更多还原

【Abstract】 Objective To measure the width of space in front of the femoral neck at different age of normal children for diagnosis such as hip disease in children as bilateral transient synovitis of the hip. Methods Four hundred and twenty normal children below 14 years old were divided into 14 groups according to their age. Every group contained 30 children. They underwent bilateral ultrasonographic assessment. The width of space in front of the femoral neck was measured and collected. The mean width value in each group was compared mutually by statistical analysis (t test). Results The mean width of space in front of the femoral neck of normal children below 14 years old was 2.0 - 5.9 mm, the range was 1.2 - 7.8 mm. Conclusions The width of space in front of the femoral neck is different at different age of normal children, the mean value below 14 years old <6 mm, the difference of the bilateral hip<1 mm.更多还原
