“…As Labelle et al [11,12], we fully recognize that there was a difference in age between our spondolisthesis cohort and our asymptomatic volunteers used for comparison. However, we believe our conclusion, little affected by this difference despite in normal individuals the PI gradually increasing with age from the onset of walking to late childhood [14,15]. Other studies have suggested that this parameter increase with age but remain stable after the age of 10 [17].…”

Recent studies suggested a predominant role of spinopelvic parameters to explain lumbosacral spondylolisthesis pathogeny. We compare the pelvic incidence and other parameters of sagittal spinopelvic balance in adolescents and young adults with developmental spondylolisthesis to those parameters in a control group of healthy volunteers. We compared the angular parameters of the sagittal balance of the spine in a cohort of 244 patients with a developmental L5-S1 spondylolisthesis with those of a control cohort of 300 healthy volunteers. A descriptive and correlation study was performed. The L5 anterior slipping and lumbosacral kyphosis in spondylolisthesis patients was described using multiple regression analysis study. Our study demonstrates that the related measures of sagittal spinopelvic alignment are disturbed in adolescents and young adults with developmental spondylolisthesis. These subjects stand with an increased sacral slope, pelvic tilt and lumbar lordosis but with a decreased thoracic kyphosis. Pelvic incidence was significantly higher in spondylolisthesis patients as compared with controls but was not clearly correlated with the grade of slipping. We showed the same ''sagittal balance strategy'' in spondylolisthesis patients as in the control group regarding correlations between pelvic incidence, sacral slope, pelvic tilt and lumbar lordosis. We believe that the lumbosacral kyphosis is a stronger factor than pelvic incidence which need to be taken into account as a predominant factor in theories of pathogenesis of lumbosacral spondylolithesis. We thus believe that increased lumbar lordosis associated with L5-S1 spondylolisthesis is secondary to the high pelvic incidence and is an important factor causing high shear stresses at the L5-S1 pars interarticularis. However, the ''local'' sagittal imbalance of the lumbosacral junction is compensated by adjacent mobile segments in the upper lumbar spine, the pelvis orientation and the thoracic spine. The result is not optimal but a satisfactory global sagittal balance of the trunk, even in the most severe grade of slipping.

IntroductionThe interdependence between the pelvis and the sagittal spinal curvatures is obvious. The leading part of the pelvic sagittal anatomy in this orientation was well established by Duval-Beaupe`re thanks to the description of the angle 'Pelvic Incidence' (PI) [14]. It is the angle between the line perpendicular to the superior plate of the first sacral vertebra (S1) at its midpoint and the line connecting this point to the middle axis of the femoral heads. It is own for every individual and independent of the position of pelvis. A strict relation was described between this anatomical parameter and the sagittal tilt of the superior plate of the sacrum, and between this sacral tilt and the amount of lumbar lordosis. So the pelvic morphology modulates the sagittal spinal alignment. During and Itoi [1,7] described also these relations using an angle complementary of the incidence. As well Jackson observed this relation between the pelvic morphology, the sacral inclination and the lumbar curvature. He expressed the pelvic sagittal shape by the 'Pelvic Lordosis' (PR-S1) [8][9][10][11][12]. The measurement of these angles is easy in most of the cases. Their reliability and their reproducibility were established. Each author agrees to use as femoral axis the middle point of the line connecting the centers of the two femoral heads.However, the exact assessment of the upper plate of the sacrum (and consequently the values of the anatomical Jean LegayeThe femoro-sacral posterior angle: an anatomical sagittal pelvic parameter usable with dome-shaped sacrum Abstract The sagittal pelvic morphology modulates the individual alignment of the spine.

“…In the current study, we present a comparison of the sagittal spinopelvic alignment between 2 groups of SD individuals, namely those that are skeletally immature (Risser's sign of 0, 1, 2, or 3) to those who are skeletally mature (Risser's sign of 5). Since PI has been reported to increase during childhood and adolescence and to remain constant when skeletal maturity is reached [6,9,10], we find it important to consider the skeletal maturity in such analyses. All of the patients with Risser's sign of 4 were excluded from the current study, because of data inconsistency: although Risser's sign of 4 has been thought as an indicator of vertebral growth cessation, there are reports emphasizing that at this stage of maturation some residual growth activity remains, and thus a potential for changes in pelvic morphology exists [30][31][32].…”

“…Pelvic incidence is hypothesized to be the fundamental pelvic parameter for three-dimensional regulation of spinal sagittal curves [8]. It is accepted that PI becomes fixed with skeletal maturation and remains constant in adulthood, unless there is a pathological process that can modify the shape of the pelvis [6,9,10]. Deviations in pelvic morphology and subsequently higher values of PI were found to be associated with spondylolisthesis and idiopathic scoliosis [11][12][13][14][15][16].…”
