Abstract

Purpose To assess the prevalence of incidentally detected lumbar spondylolysis in children. Materials and Methods 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. Results 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, p > 0.05). The prevalence of spondylolysis in boys was higher than that in girls (15/479 [3.1%] vs. 5/330 [1.5%], p > 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%], p > 0.05). L5 was the most common level of spondylolysis (76.2%); one 8-year-old boy had two-level 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%). Conclusion 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.

목적 소아에서 우연히 발견되는 요추 척추분리증의 유병률을 평가하고자 한다. 대상과 방법 2014년 3월부터 2018년 12월까지 복부-골반 컴퓨터단층촬영술을 시행한 11세 미만의 환자 809명(평균나이 7.0 ± 2.7세, 남아:여아 = 479:330)의 자료를 후향적으로 분석하였다. 척추분리증의 유무, 척추분리증이 있는 위치, 그리고 편측성(일측성 혹은 양측성)을 기록하였다. 척추분리증의 유무에 따라 환자군 spondylolysis (이하 SP) 그룹과 non-SP 그룹으로 나누었다. 결과 20명의 환자에서 21개의 척추분리증이 확인되었다(20/809, 2.5%). SP 그룹의 평균 나이가 non-SP 그룹보다 많았다(7.8 ± 1.8세 vs. 6.9 ± 2.7세, p > 0.05). 남아에서 여아보다 유병률이 높았다(15/479 [3.1%] vs. 5/330 [1.5%], p > 0.05). 만 6-10세의 학령기 연령에서 만 0-5세의 미취학 연령보다 유병률이 높았다(17/538 [3.2%] vs. 3/271 [1.1%], p > 0.05). 척추분리증은 요추 5번에서 가장 흔하게 보였고(76.2%), 8세 남아에서 두 개의 요추에서 척추분리증을 보였다. 10세 남아에게서 척추분리전방전위증이 확인되었다(1/809, 0.1%). 11건의 일측성 척추분리증은 확인되었다(11/21, 52.4%). 결론 본 연구에서 11세 미만의 환자에서 척추분리증의 유병률은 2.5%였다. 척추분리증은 여아보다는 남아에게서, 미취학 연령군보다는 학령기 연령군에서 더 높은 유병률을 보였으나, 통계학적으로 유의미한 차이는 없었다.
