Distribution and imaging characteristics of spina bifida occulta in young people with low back pain: a retrospective cross-sectional study

Abstract Purpose Spina bifida occulta (SBO) is one of the most common congenital spinal deformities. Although many studies have demonstrated influence lumbosacral dysplasia on low back pain (LBP) in young athletes, there been few SBO among people other occupations. The purpose this study to investigate distribution with LBP and classify from perspective lamina development. Methods X-ray films 148 patients were analyzed quantify abnormal laminae. Results Of patients, 93 (61.49%) had SBO: 83 cases involved S1 alone, 2 L5–S1, 5 S1–2, S1–4, 1 L4–S4. According degree defect, divided basis five grades: 9 grade I, 53 II, 23 III, 8 IV. classified by shape laminae into 4 types: 15 type a, 11 b, 37 c, 30 d. Conclusion Among that we surveyed, dysplasia, which frequently involves segment. Most are developmental stage spinous process, an laminar growth direction stenosis morphologies SBO.
