Which listing is associated with a long leg?

• A. Pi
• B. Ex
• C. As
• D. In

Answer: (C)

A long-leg pattern shows when the innominate or sacral base tilts forward on the side of the longer leg. In the standard listing notation this is labeled as anterior-superior, abbreviated AS. That anterior-superior orientation on that side lengthens the leg relative to the other side when you assess pelvic landmarks and leg length. The other directional listings describe opposite or different patterns that don’t produce the same leg-length discrepancy, so they don’t fit the long-leg finding.
