Question

what is the most likely malposition for an anterior glide restriction of the ilium?
pi
ps
ai
as

Explanation:

In the context of ilium malpositions related to anterior - glide restriction, a posterior superior (PS) malposition of the ilium is likely to cause such a restriction. This is based on biomechanical knowledge of pelvic joint mechanics where a posterior - superior displacement can limit the normal anterior glide motion of the ilium.

Answer:

PS
