摘　　要：为了探讨腰骶椎隐裂发生率特点及相关因素,回顾分析了1082例螺旋CT检查信息,以12个月为间隔将18岁以下508例共分18小组,比较腰骶椎隐裂发生率有无统计学差异,找出差异的年龄段规律。并统计574例18岁以上隐裂发生率,结果显示0岁～8岁、8岁～14岁、14岁～18岁小组发生率分别为94.0%～97.2%、46.9%～52.4%、19.1%～20.8%,各年龄段内小组发生率无统计学差异,三大组总体发生率递减,有统计学差异,18岁以上为16.0%,由此我们可以把骨性椎弓发育分为三期:0岁～8岁为生理性未闭合期,8岁～14岁为闭合过渡期,14岁以上为闭合稳定期。To probe the domestic incidence of spina bifida occulta and its related factors, 1 082 cases of spiral CT images were studied retrospectively. The 508 cases below 18 years old were divided into 18 small groups with a 12-month interval. Incidence of spina bifida occulta in different groups were compared to find relationships with age. And statistics the Incidence of spina bifida the574 cases above 18 years . This study showed that the incidence ranges were 94.0%～97.2%, 46.9%～52.4%、19.1%～20.8% in the 0y～8y groups, 8y～14y groups 14y～18y groups and 18～ groups, respectively. There was no significant difference among the small groups of every age range, and the incidence decreased in the threegroup range with significant difference. The incidence ranges were 16.0% in the above18years groups. Therefore, the development process of bony vertebral arches can be divided into 3 periods：unclosed period for 0y～8y, transition period for 8y～14y, closed period for above 14y.
