“…Spino-pelvic alignments of the general population, patients with LDH, and with SPL have been studied in past decades. In clinical practice, LDH patients sometimes present with a forward-bending posture, but SPL patients are sometimes with forward-backing posture [8][9][10][11] . There are some studies on sagittal spinal alignment of LDH and SPL.…”

Background: Sagittal spinopelvis plays an important role in occurrence and development in spinal disorders, no study was focused on the differences of spinopelvic alignment between patients with LDH and patients. Objective: to study differences of spinopelvic alignment and to analyze differences of correlation between sagittal alignment parameters among patients with lumbar disc herniation (LDH), spondylolisthesis (SPL) and normal population. Methods: Standard up-standing antero-posterior and lateral X-ray of the whole spine were preformed in all subjects. Evidence of LDH was confirmed by CT or MRI. SPL was diagnosed by X-ray or MRI. The parameters were measured including TK, LL, PI, SS, PT and SVA in lateral radiography. Results: 60 patients with LDH, 62 patients with SPL and 57 normal were included. Significant differences for the SS, TK, LL and SVA (P <0.05) was found among three groups. PI of SPL patients was the highest among the three groups (P <0.05). PT of both SPL patients and LDH patients were significant higher than controls’ (P <0.05). LL of LDH patients was the lowest among the three groups (P <0.05). PI was less correlated with LL (P <0.05) in patients with LDH and SPL. PT was more strongly negative correlated with SS, LL and TK in LDH group (P <0.05). SS was more strongly positive correlated with TK (P <0.05), and SS and LL were more strongly negative correlated with SVA (P <0.05) in LDH patients. Conclusions: the present results indicated a disharmonious spinopelvic relationship and exhibited different compensatory models of spine to adapt changes in spinal alignment in LDH patients and SPL patients.

“…The correlation between the abnormal anatomical sequence of spondylolisthetic segment and the spino-pelvic sagittal morphological changes was often paid less attention. [32,33] Ferrero et al [5] analyzed the spinal sagittal morphology of 654 patients with DLS in L4/5 segment, and suggested that the loss of lordosis angle in spondylolisthetic segment was closely related to the morphological changes of spino-pelvic sagittal alignment. Kong et al [15] conducted a retrospective study on 53 patients with L4/5 DLS who underwent interbody fusion, and analyzed the in uence of SA, SD and intervertebral space height on postoperative spino-pelvic sagittal parameters.…”

Background: Degenerative lumbar spondylolisthesis (DLS) has been a common disease that make increasing patients suffer from different degrees of low back pain and radicular symptoms. At present, the incidence of kyphosis in DLS and the differences in spinal sagittal morphology between kyphotic and non-kyphotic DLS still remain unclear. Our study aimed to determine the incidence of kyphosis in DLS, explore the characteristics of spondylolisthetic and spino-pelvic sagittal parameters, and evaluate the impact of kyphosis on the life quality of patients with DLS.Methods/Design: All 108 patients with L4/5 low-grade DLS were enrolled and divided into kyphotic and non-kyphotic group. 2 spine surgeons who have certain clinical experience were selected to measure the spondylolisthetic and spino-pelvic parameters, as well as visual analogue scale (VAS) and Oswestry disability index (ODI). Differences between the 2 groups and characteristics of measurements were analyzed.Results: The inter-observer agreement of all parameters between the 2 spine surgeons were excellent with each ICC > 0.75. Kyphotic group had higher SA, SD, SDM, SAM, PDH, PT and SVA, and lower ADH, SS and LL than those in non-kyphotic group (p < 0.01). There was no significant difference in PI and TK between the two groups (p > 0.05).Conclusion: The incidence of kyphotic spondylolisthesis in patients with L4/5 low-grade DLS is 16.7%. Compared with those in non-kyphotic group, patients with kyphosis show inferior results of spondylolisthetic parameters, more severe loss of LL, more obvious pelvic retroversion and trunk anteversion, which indicates worse spino-pelvic sagittal balance. In addition, their quality of life was significantly lower than that of patients in non-kyphotic group.

Background: few studies focusing on the differences of spinopelvic alignment between patients with LDH and patients with SPL were reported. The aim of this study was to study differences of spinopelvic alignment and to analyze differences of correlation between sagittal alignment parameters among patients with LDH and SPL, and normal population. Methods: Standard up-standing antero-posterior and lateral X-ray of the whole spine were preformed in all subjects. Evidence of LDH was confirmed by CT or MRI. SPL was diagnosed by X-ray or MRI. The parameters were measured included TK, LL, PI, SS, PT and SVA in lateral radiography. Results: 60 patients with LDH, 62 patients with SPL and 57 normal were included. Significant differences as for the SS, TK, LL and SVA (P <0.05) was found among three groups. PI of SPL patients was the highest among the three groups (P <0.05). PT of both SPL patients and LDH patients were significant higher than controls’ (P <0.05). LL of LDH patients was the lowest among the three groups (P <0.05). PI was less correlated with LL (P <0.05) in patients with LDH and SPL. PT was more strongly negative correlated with SS, LL and TK in LDH group (P <0.05). SS was more strongly positive correlated with TK (P <0.05), and SS and LL were more strongly negative correlated with SVA (P <0.05) in LDH patients. Conclusion: Those results showed a disharmonious spinopelvic relationship and exhibited different compensatory models of spine to adapt changes in spinal alignment in LDH patients and SPL patients.
