 We investigated the relation between the pelvic morphologic angle (PRS1) and total sagittal spinal alignment in 54 healthy adult volunteers. The following parameters were measured on lateral whole-spine standing radiographs:distance between the C7 plumb line and the posterior superior corner on the superior margin of S1 (SVA),lumbar lordotic angle (LLA),sacral slope (SS),pelvic tilting angle (PA),and pelvic morphologic angle (PRS1). The coefficient for the correlations between PRS1 and SS and LLA was r=-0.81 (p<0.01) and r=-0.50 (p<0.05),respectively. The close results clearly showed a relationship between the pelvic and the spinal parameters. LLA is closely related to the orientation of the pelvis,which is expressed by the SS,which,in turn,is strongly influenced by the PRS1. Our results showed that PRS1 had a high correlation coefficient between both of PA and SS,and the relationship to LLA was statistically significant.
