Abstract:
Objective To investigate the differences in some measured paremeters on spino-pelvic sagittal X-ray films in middle-aged and elderly patients between lumbar spondylolysis and isthmic spondylolisthesis,and to explore the predictors that the spondylolysis at lumbar 5 may develope into spondylolisthesis in order to provide imaging details for the clinical treatment of teenage patients with lumbar spondylolysis.Methods Imaging data of 60 patients with spondylolysis at lumbar 5 and other 60 with isthmic spondylolisthesis in middle or elder age in our hospital were analyzed retrospectively,and a control group with 60 normal volunteers were recruited in this study.Some parameters including the angles of pelvic incidence (PI),pelvic tilt (PT),sacral slope (SS),lumbar-sacral angle (LSA)and lumbar lordosis (LL),and the sagittal vertical axis (SVA)were measured in sagittal radiographs of the spine and pelvis. Differences in sagittal parameters among 3 groups were analyzed by one-way variance analysis and SNK-q test.Results The PI,PT, SS and LL were higher,and LSA was lower in patients with isthmic spondylolisthesis than those in the control group and lumbar spondylolysis one (P<0.05).However,there was no significant difference in SVA (P>0.05).No significant differences in all spino-pelvic sagittal parameters were found between lumbar spondylolysis group and the control (P>0.05).Conclusion Such spino-pelvic sagit-tal parameters as PI,PT,SS,LL and LSA on X-ray film can be regarded as predictors that lumbar 5 spondylolysis may develop into spondylolisthesis and may provide imaging reference for the clinical treatment of teen-age patients with lumbar spondylolysis.
