To assess the prevalence of incidentally detected lumbar spondylolysis in children.
We retrospectively reviewed the data of 809 patients under the age of 11 years (mean age, 7.0 ± 2.7 years; boys:girls = 479:330) who underwent abdominal and pelvic CT between March 2014 and December 2018. We recorded the presence, level, and laterality (unilateral or bilateral) of spondylolysis. Patients were divided into two groups based on the presence of spondylolysis: the spondylolysis (SP) and non-SP groups.
In total, 21 cases of spondylolysis were detected in 20 patients (20/809, 2.5%). The mean age of the SP group was higher than that of the non-SP group (7.8 ± 1.8 vs. 6.9 ± 2.7 years, > 0.05). The prevalence of spondylolysis in boys was higher than that in girls (15/479 [3.1%] vs. 5/330 [1.5%], > 0.05). The prevalence of spondylolysis in school-age children (6-10 year olds) was higher than that in preschool-age children (0-5 year olds) (17/538 [3.2%] vs. 3/271 [1.1%], > 0.05). L5 was the most common level of spondylolysis (76.2%); one 8-year-old boy had twolevel spondylolysis. One case of isthmic spondylolisthesis was detected in a 10-year-old boy (1/809, 0.1%). There were 11 unilateral spondylolysis cases (11/21, 52.4%).
In our study, the prevalence of spondylolysis in children under the age of 11 was 2.5%. The prevalence was higher in boys than in girls and in school-age than in preschool-age children, despite the lack of any statistically significant differences.
评估儿童偶然发现的腰椎峡部裂的患病率。
我们回顾性分析了2014年3月至2018年12月期间接受腹部和盆腔CT检查的809例11岁以下患者（平均年龄7.0±2.7岁；男∶女 = 479∶330）的数据。我们记录了峡部裂的存在、位置及侧别（单侧或双侧）。根据是否存在峡部裂将患者分为两组：峡部裂（SP）组和非SP组。
共在20例患者中检测到21例峡部裂（20/809，2.5%）。SP组的平均年龄高于非SP组（7.8±1.8岁 vs. 6.9±2.7岁，P>0.05）。男孩峡部裂的患病率高于女孩（15/479[3.1%] vs. 5/330[1.5%]，P>0.05）。学龄儿童（6 - 10岁）峡部裂的患病率高于学龄前儿童（0 - 5岁）（17/538[3.2%] vs. 3/271[1.1%]，P>0.05）。L5是峡部裂最常见的位置（76.2%）；一名8岁男孩有两处峡部裂。在一名10岁男孩中检测到1例峡部裂性脊椎滑脱（1/809，0.1%）。有11例单侧峡部裂（11/21，52.4%）。
在我们的研究中，11岁以下儿童峡部裂的患病率为2.5%。尽管缺乏任何统计学上的显著差异，但男孩的患病率高于女孩，学龄儿童的患病率高于学龄前儿童。
