Which view provides the most reliable observation of posterior pelvic tilt?

• A. Lateral
• B. Anterior
• C. Posterior
• D. Superior

Answer: (A)

Posterior pelvic tilt is a movement in the sagittal plane, meaning you observe how the pelvis tilts forward or backward when looking from the side. The side (lateral) view is the most reliable for catching this because it presents the pelvis in profile, showing the orientation of the ASIS relative to the pubic symphysis and the relationship to the lumbar spine. In a posterior tilt, the pelvis rotates backward. In a lateral view, this backward rotation is visible as a change in the pelvis’s profile and a tendency for the lumbar spine to lose some of its lordotic curve. You can assess the tilt angle more clearly from the side than from any front-back or top-down viewpoint. Frontal or back views mostly reveal side-to-side (coronal) alignment and are not sensitive to rotation in the sagittal plane, and a superior view from above doesn’t capture the front-to-back orientation of the pelvis at all. So the lateral view provides the clearest and most reliable observation of a posterior pelvic tilt.
