The radiological evaluation included measurement of the scoliosis angle using the Cobb method, the direction of the scoliosis, the relationship between the intercrest line and the L-5 vertebra, lateral listhesis, segmental angle, distance from the center of the sacral line to the apical vertebra, degenerative listhesis anteriorly or posteriorly or both, and lordosis angle. In addition, the lateral osteophyte difference, disc index, and severity of osteoporosis were measured. The pain and disability outcomes were assessed using the visual analog scale and the Oswestry Disability Index (ODI) relative to severity of the angle of scoliosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean initial and final scoliosis angles were 14\u00b0 \u00b1 5.4\u00b0 and 25\u00b0 \u00b1 8.5\u00b0, respectively. The initial disc index at the L-3 vertebra (Spearman \u03c1 = 0.7, p &lt; 0.001), the sum of the segmental wedging angles above and below the L-3 vertebra (\u03c1 = 0.6, p &lt; 0.001), and the initial disc index at the apical vertebra (\u03c1 = 0.6, p &lt; 0.001) were correlated with the last follow-up angle of the scoliosis. By contrast, there was no statistically significant correlation between the initial segmental angles at L2\u20133 and L3\u20134 and the final follow-up scoliosis angle (\u03c1 = 0.2, p = 0.67; and \u03c1 = 0.1, p = 0.22; respectively). When the authors separated the patients into 3 groups according to the sum of the segmental angles above and below L-3 (&lt; 5\u00b0, 5\u00b0 to 10\u00b0, and &gt; 10\u00b0), they found that 3 (42.9%) of 7, 8 (66.7%) of 12, and 6 (75.0%) of 8 patients in the 3 groups showed increases of greater than 10\u00b0 in scoliosis angle. The mean distance from the center of the sacral line to the apical vertebra was 36.0 \u00b1 9.7 mm, and the distance correlated with the measurement of the last follow-up angle of the scoliosis (\u03c1 = 0.6, p &lt; 0.001). The mean angle of the scoliosis was significantly greater when the intercrest line passed through the L-5 or L4\u20135 disc space than when the line passed through the L-4 vertebral body (31.4\u00b0 \u00b1 7.9\u00b0 vs 21.8\u00b0 \u00b1 6.7\u00b0, p = 0.01). The ODI correlated with the measurement of the angle of the scoliosis (\u03c1 = 0.6, p &lt; 0.001). Age, sex, osteoporosis, the direction of the scoliosis, listhesis of coronal and sagittal planes, the lateral osteophyte difference, and the vertebral body index did not correlate with curve progression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings of this study demonstrated that the progression of DLS was affected by the relationship between the intercrest line and the L-5 vertebra. When L-5 was deep seated, progression of DLS was found. Asymmetrical change in the disc space above and below the L-3 or apical vertebra may also be an important predictor of curve progression.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2011.6.spine10929","type":"journal-article","created":{"date-parts":[[2011,7,22]],"date-time":"2011-07-22T14:04:46Z","timestamp":1311343486000},"page":"558-566","source":"Crossref","is-referenced-by-count":39,"title":["Risk of progression of degenerative lumbar scoliosis"],"prefix":"10.3171","volume":"15","author":[{"given":"Jun-Yeong","family":"Seo","sequence":"first","affiliation":[{"name":"2Department of Orthopaedic Surgery, Jeju National University, Jeju Self Governing Province, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kee-Yong","family":"Ha","sequence":"additional","affiliation":[{"name":"1Department of Orthopaedic Surgery, College of Medicine, The Catholic University of Korea, Seoul;
