Introduction. Variability of sagittal spinal-pelvic balance parameters results to a change of the types of standing. Material and methods. In the groups of asymptomatic volunteers (n=30 at the age of 20–30) and patients with lumbar degenerative disc diseases (n=42, at the age of 20–40) were investigated parameters of sagittal spinal-pelvic balance and the location of the lower limb joints relative to the line gravity. Results. In asymptomatic volunteers with all types of standing an optimal matching parameters of sagittal spinal-pelvic balance were noted. In patients a flattening of the lumbosacral sagittal contour compensated by an increase of the sagittal spinal list at the types of standing 1 and 2 (19.0% and 45.2%, respectively); one compensated by pelvis retroversion and hyperextension position in the hip joints at the types of standing 3 and 4 (23.9% and 11.9%, respectively). Discussion and Conclusion. Lumbar lordosis flattening – that is, flexing position of suprapelvic part of the body – and compensatory pelvic retroversion with the hip joints extension position create torque in the lumbosacral segment, which counteracts the persistent tension of stabilizing muscles of the lumbar spine. This mismatch of sagittal spinal-pelvic balance parameters creates a biomechanical conditions for the further progression of degenerative lumbar disc diseases.
