To research on specific clinical features of isthmic lumbar spondylolisthesis in badminton athletes and explore the morpho- logical study of degenerative spondylolisthesis patients with spine pelvic sagittal plane. In order to further study the characteris- tics of morphology, 1,100 patients with isthmic lumbar spondylolisthesis and degenerative spondylolisthesis, receiving clinic treatment by a hospital from January 2009 to February 2016, were randomly selected as the research object and all of them have complete image data. Patients were divided into spondylolysis group (550) and degeneration group (550). The relative spine and pelvic sagittal index of two groups of patients were collected, mainly covering the following aspects: inclination of pelvis, pelvic incidence angle and lumbar lordosis angle and so on. At the same time, the following parts of two groups were measured: angle of lumbar spondylolisthesis, spondylolisthesis rate, spondylolisthesis distance to analyze comparatively the above patients with these indicators. The results show that the angle of lumbar lordosis, thoracic posterior lobe and spondylolysis angle of the group of patients was significantly higher than that of degeneration group, meeting P < 0.05, which has statistical significance. The patients in the degeneration group were superior to spondylolysis group in vertical distance of sagittal axial. The comparison between two groups of patients does not exist statistical significance in following aspects: namely morphological parameters of the pelvis, pelvic tilt angle, sacral inclination angle and lumbar spondylolisthesis rate and so forth. Therefore, we can draw the conclusion that the isthmic lumbar spondylolisthesis of badminton players is similar to degenerative spondylolisthesis in pelvic morphology, but the former has larger thoracic kyphosis, lumbar lordosis and spondylolisthesis angle than the latter.
