Which listing most commonly produces a long leg?

Answer: (C)

In chiropractic palpation, a long leg pattern is most often caused by the innominate bone tilting forward, i.e., an anterior rotation of the pelvis. This anterior superior listing shifts the orientation of the hip joint in a way that makes the leg on that side appear longer when measured or observed in stance. Because of how the pelvis and acetabulum align, this forward tilt reliably produces a long-leg presentation in common assessments.

The other patterns involve posterior or inferior tilts of the innominate (or more complex combinations) and tend to produce a short leg or a mixed presentation rather than a consistent long-leg pattern, so they’re less likely explanations for a long leg.
