Which listing is associated with a short leg?

• A. In
• B. Pi
• C. As
• D. Ex

Answer: (B)

In this listing system, the pattern of a short leg comes from the way the pelvis and sacrum are oriented. The Pi listing encodes a posterior-inferior position of the pelvic ring on the short-leg side, which tilts the pelvis and makes the leg appear shorter when standing. That functional short leg is why Pi is associated with this finding. The other directional listings describe different pelvic/spinal orientations and would align with other patterns, not the short-leg presentation described here.
