摘　　要：目的探讨寰枢椎侧方半脱位（AALSD）的发生率与性别、年龄及齿突侧块间距和的相关性分析。方法回顾性分析517例寰枢椎受检者中62例AALSD的CT资料,按性别、年龄、齿突侧块间距和进行分组,观察AALSD发生率与性别、年龄、齿突侧块间距的关系。结果 517例受检者中寰枢椎半脱位（AALSD）62例,发生率为12.0%,男性和女性AALSD发生率分别为12.1%（31/257）、11.9%（31/260）,差异无统计学意义（χ^2=0.020,P=0.961）。〈15岁、15-30岁、31-45岁、46-60岁、〉60岁年龄组AALSD的发生率分别为3.5%（2/57）、6.0%（5/83）、19.5%（25/128）、14.5%（24/165）、7.1%（6/84）,各年龄组中AALSD发生率差异有统计学意义（χ2=13.026,P=0.011）。1.0-3.0 mm、3.1-5.0 mm、5.1-7.0 mm、7.1-9.0 mm、〉9.0 mm齿突侧块间距和各分组AALSD发生率分别为0（0/40）、5.5%（11/199）、11.7%（21/180）、23.4%（18/77）、57.0%（12/21）,在各齿突侧块间距和分组中AALSD发生率差异有统计学意义（χ2=37.758,P=0.000）。结论 AALSD发生率随年龄增大呈先增高再降低的趋势,AALSD发生率随齿突间距和增大而增高,但AALSD发生率在男女性别上无差别。Objective To explore the relationship between incidence of the atlantoaxial lateral subluxation （AALSD） and sex, age and bilateral lateral atlanto dental interval. Methods CT data of 517 cases of atlantoaxial, included 62 AALSD cases were retrospectively analyzed. Incidence of the AALSD in different gender, age group and bilateral lateral atlanto dental interval were recorded, so as to observe the relationship between incidence of the AALSD and sex, age, bilateral lateral atlanto dental interval. Results All of 517 patients, there were 62 AALSD cases, the total incidence of the AALSD was 12.0%, the incidence of male and female were 12.1% （31/257） and 11.9% （31/260）, there was not significantly difference between male and female （X^2=0.020, P=0.961）. The incidence of the AALSD for age 〈15, 15-30, 31-45, 46-60 and 〉60 were 3.5% （2/57）, 6.0% （5/83）, 19.5% （25/128）, 14.5% （24/165） and 7.1% （6/84）, respectively. There was significantly difference in the different age groups （X^2=13.026, P=0.011）. The incidence of the AALSD for lateral atlanto dental interval 1.0-3.0 mm, 3.1-5.0 mm, 5.1-7.0 mm, 7.1-9.0 mm and 〉9.0 mm were 0.0% （0/40）, 5.5% （11/199）, 11.7% （21/180）, 23.4% （18/77） and 57.0% （12/20, respectively. There was significantly difference in them （X^2=37.758, P=0.000）. Conclusion The incidence of AALSD increases with increasing of the age at first and then decreases, the incidence of AALSD increases with increasing of bilateral lateral atlanto dental interval, but not significantly difference between male and female.
