Evaluation of pelvic orientation, type of spinal curvature, and posture in the sagittal plane

The lumbar-pelvic-femoral complex is of fundamental importance for the posture of the trunk and the position of the lower limbs. The orientation of the pelvis in the sagittal plane determines both different X-ray types of spinal curvature, as well as different types of body posture, which we evaluate visually and by palpation during the physical examination. Evaluation of body posture in the sagittal plane should therefore begin with an assessment of the orientation and position of the pelvis. The type of pelvic orientation also makes it possible to compare and connect the results of these two different methods of examination and evaluation. The general result of degeneration of different types of spine is its kyphotization. Different types of posture have a typical combination of shortening or weakening of different muscle groups.
