With a posterior pelvic tilt, more weight bearing responsibility is placed on the ____.

When the pelvis tilts backward, the lumbar spine goes into more of a flexed posture (reduced curve). In this flexed position, the facet joints tend to unload because their alignment opens up, while the intervertebral discs take on the primary compressive load across adjacent vertebrae. The discs are designed to distribute that weight across levels, so a posterior tilt shifts more weight-bearing responsibility onto the discs rather than the facet joints.
