摘要
目的通过测量1494例正常骨盆正位片的中心边缘角（center-edge angle，CEA），得出国人髋关节CEA的正常值范围，指导临床阅读骨盆正位片。方法测量4岁以后健康人群骨盆正位片的CEA，4～18岁按年分组，〉18岁每10年分为一组。同时采用Ⅲ型髋臼2种CEA测量方法（经典CEA和改良CEA），统计分析测得的各个年龄组的正常参考值和数值一年龄变化曲线。结果CEA4岁时为21．62°，9岁时增大至25．07°，18岁时增大为32．14°，18岁之后，CEA基本在30°～34。波动。Ⅲ型髋臼主要见于4～9年龄组，这时二种CEA测量相差10。～12。左右。结论10～14岁是CEA快速增大期，Ⅲ型髋臼主要见于4～9岁年龄组，此时经典CEA〉25°且改良CEA〉15°可认为是正常的。
Objective To define the value of the center-edge angle （CEA） of normal hips in a healthy Chinese population. Methods The classical center-edge angle （CCEA） and modified centeredge angle （MCEA） were measured onthe anterior-posterior pelvic radiographs of 1494 healthy Chinese older than 4 years. According to their ages, the enrolled individuals were divided into different groups： in the individuals aged 4 to 18 years old, they were grouped by year; in the individuals over 18, they were grouped by 10 years. The reference range of each group and the CEA corresponding to age were analyzed statistically. Results The mean CEA of 4-year-old group was 21.62°, which increased to 25. 07° in 9-year-old group and to 32. 14° in 18-year-old group. In healthy individuals over 18 years old, it fluctuates between 30° and 34°. Type III acetabular rooves according to Ogata classification mainly appears in 4-9 years old groups, in which the difference between CCEA and MCEA is 10-12°. Conclusions CEA increases fast from 10 to 14 years old. Type III acetabular rooves mainly appears in 4-9 years old groups, when it is normal if CCEA is above 25°and MCEA is above 15°.
