What should be palpated on the pelvis when examining from the side view?

When examining the pelvis from the side view, palpating the ASIS (anterior superior iliac spine) and PSIS (posterior superior iliac spine) is crucial due to their prominence and significance in postural assessment. The ASIS serves as an important landmark for evaluating pelvic alignment and identifying any asymmetries in the pelvis. Similarly, the PSIS provides reference points for assessing the position of the sacrum and overall pelvic tilt.

These bony landmarks are essential for understanding how the pelvis is positioned in relation to the spine and lower limbs, which can impact overall posture and movement mechanics. By focusing on these areas, practitioners can gather critical information about a person's alignment, potential compensation patterns, and how these may contribute to various movement issues or discomfort.

While the other options may include anatomical structures relevant in different contexts—such as the greater and lesser trochanters being significant for hip mechanics, or the pubic symphysis and coccyx relating to pelvic floor assessments—they do not provide the same immediate insights into pelvic alignment from the side view as the ASIS and PSIS. Thus, palpating these specific points is essential for comprehensive postural analysis.
