| 【Ａbstract】 Objective：Ｔo investigate the relationship between lumbar intervertebral disc degeneration and degree of scoliosis，segmental lordosis in degenerateive lumbar scoliosis.Ｍethod：84 cases with degenerative lumbar scoliosis（mean age，64.1±5.3 years） were recruited，a total of 252 discs were inverstigated including disc asymmetric index between apex intervertebral disc and adjacent discs as well as the average relative signal intensity in T2WI sagittal image between nucleus pulpous in lumbar disc and cerebrospinal fluid. Spearmann analysis was used to evaluate the correlation between disc asymmetric index and degrees of scoliosis，average relative signal intensity and lumbar lordosis.Result：The average intervertebral height was 40.1±1.8 mm in the convex side and 38.3±1.1 mm in the concave side，which showed significant difference between two side（P＜0.05）. The disc asymmetric index was 0.042±0.018，which showed positive correlation between disc asymmetric index and degree of scoliosis（P＜0.05）.The average relative signal intensity of lumbar intervertebral disc and cerebrospinal fluid in T2WI sagittal image were as follows：Ⅰ level 8 cases，Ⅱ level 27 cases，Ⅲ level 32 cases and Ⅳ level 17 cases, with the average relative signal intensity showing negative relationship with lumbar lordosis（P＜0.05）.Ｃonclusion：The degree of scoliosis is positive related to the disc asymmetric index, and the decrease of segmental lordosis is associated with the degree of disc degeneration. |
