A wide gluteal fold indicates which listing?

• A. EX
• B. PI
• C. IN
• D. AS

Answer: (C)

A wide gluteal fold signals an inferior innominate listing. When the innominate on one side tilts downward, the lower portion of the pelvis sits lower relative to the sacrum, causing the buttock crease on that side to open up and the gluteal fold to appear wider. This soft-tissue pattern is a practical clue that helps identify this specific pelvic misalignment.

Other patterns of pelvic orientation would alter the gluteal region differently, so they wouldn’t produce the same widening of the fold. The key idea is that the width of the gluteal fold reflects the downward/ inferior tilt of the innominate on that side.
