Text of Posterior Inferior Subluxation Ilium

Life University Gonstead Study Club

Pelvis

Directions of Ilium Misalignment The basic directions that the ilium can become misaligned with the sacrum Anterioward Posteriorward Medialward Lateralward

2 Life University Gonstead Study Club

Where the Misalignment Occurs Occurs in the sacroiliac articulation Tendency to think subluxations occur at the hip joint

Emphasis is placed on the Ilium An AS/PI misaligned ilium travels in an arc due to: Nature of the auricular surfaces of the joint Angle of the pelvis itself
