A wide gluteal fold is most consistent with which listing?

• A. PI
• B. AS
• C. IN
• D. EX

Answer: (C)

A wide gluteal fold points to a specific pelvic orientation: the innominate on that side is rotated in a way that creates a broader crease between the buttock and thigh. In this listing system, that pattern is labeled IN. So when you see a noticeably wider gluteal fold, the best match is IN, because the fold widening aligns with that inward/downward innominate rotation.

The other patterns describe different directions of pelvic rotation, which would produce different crease patterns and aren’t consistent with a simply widened gluteal fold.
