Abstract:
Objective To explore the risk factors related to the development and progression of lumbar degenerative spondylolisthesis (LDS).Methods A total of 71 patients with LDS or degenerative spinal stenosis (DSS) were retrospectively.Thirty-six patients with LDS (group LDS) and 35 patients with DSS (group DSS) were enrolled.Spinopelvic parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), regional lumbopelvic lordosis angles (PR-LI, PR-L2, PR-L3, PR-L4, PR-L5), pelvic morphology (PR-S1), lumbar 4 slope (L4 S) and lumbar 5 slope (L5 S) were assessed on whole spine lateral radiographs in a standing position.All the parameters from LDS will compared with those of DSS and normal population respectively, Student's t-test was used to compare each parameter among the LDS, DSS and normal population.Results PI [ (57.67±11.78) °], SS [ (37.83±9.17) °] and LL [ (54.65±11.45) °] in group LDS were significantly greater than those of group DSS [ (44.47±8.75) °, (28.18±9.02) °, (38.97±15.59) °] and normal reference value [ (44.75±9.01) °, (33.57±7.64) °, (48.75±10.03) °] (P＜0.05).L4 S [ (8.18±9.98) °] and L5 S [ (19.96±8.33) °] in group LDS were greater than the group DSS[ (3.32±7.95) °, (10.87±8.02) °] (P＜0.05).The PR-L4 [ (57.63±13.44) °], PR-L5 [ (45.76±10.92) °] and PR-S1 [ (27.91±10.41) °] in group LDS were significantly smaller than those of group DSS [ (65.48±10.70) °, (56.33±9.15) °, (38.63±7.29) °] (P＜0.05).Conclusion Greater PI may lead to the development and progression of lumbar degenerative spondylolisthesis.L5 S is a parameter that can be used to predict the risk of LDS.The lower regional lumbopelvic lordosis angles in LDS were smaller than those of DSS.
