Over the last 30 years, many authors have suggested that the shape of the human spine in the sagittal plane is helpful in understanding its physiology and pathology. This paper presents the current views and Polish no-men-clature used for the assessment of the morphology and position of the pelvis in the sagittal plane. The va-lues of particular radiographic parameters are presented for healthy individuals and for patients with selected spinal pathologies. Moreover, the paper discusses the practical application of the radiographic parameters that describe the shape and position of the pelvis in the sagittal plane.
