Abstract:
STUDY DESIGN: A retrospective cross-sectional study OBJECTIVES: To analyze the prevalence and characteristics of lumbar scoliosis using plain abdominal X-rays, according to age. LITERATURE REVIEW SUMMARY: The single lumbar curves of adolescents have shown 10 ~20% idiopathic scoliosis, but the reported prevalence of adult lumbar scoliosis ranges from 2.5 to 7.5%. In Korea, there is no useful basic data concerning lumbar scoliosis. MATERIALS AND METHODS: A total of 2877 plain abdominal radiographies (supine and erect), taken at our hospital, between August 2001 and June 2002, were retrospectively investigated. The ages of the patients ranged from 11 to 80 years, and the patients were grouped according to age. The prevalence, Cobb angle, ratio of males and females, ratio of right and left curves, location of end and apex vertebra, the number of involved vertebra in primary curve, amount of rotation and osteophytes were all examined. RESULTS: The overall prevalence of lumbar scoliosis was 4.3% (N=124), but rapidly increased after the sixth decade. The average Cobb angle was 16.2 degree. A positive correlation was found between the Cobb angle and age (r=0.275, P<0.05). The ratios of males to females and of the right to left curves were both about 1:2. The most common sites of upper end vertebra were T12 and L1, that of the lower end vertebra L4 and those of the apex L2 (N=48) and L3 (N=40). Most (N=111) had grade 1 rotation. With regard to the magnitude of the curves, no other factors were statistically significant. CONCLUSIONS: De novo scoliosis can be considered to develop rapidly after the sixth decade. The Cobb angle had a positive correlation with age (r=0.275, p<0.05). These data are thought could be useful and valuable for future study of lumbar scoliosis.
