Which statement about the ILA during unilateral sacral flexion is true?

  1. ILA is shallow

  2. ILA is deep

  3. ILA position is irrelevant

  4. ILA shifts to the opposite side

The correct answer is: ILA is deep

During unilateral sacral flexion, the sacrum moves forward on one side while the other side remains relatively stationary or may extend. This movement influences the position of the Inferior Lateral Angle (ILA). In unilateral sacral flexion, the ILA on the side of flexion becomes deeper due to the forward motion of the sacrum, which causes the ILA to become more pronounced or deep as it angles downward and inward. Thus, observing the ILA on the flexed side reveals a deeper position compared to its usual anatomical location when the sacrum is in a neutral position. Understanding this mechanism is crucial for identifying sacral dysfunctions and guiding appropriate osteopathic manipulative treatments. The other aspects regarding whether the ILA is shallow, irrelevant, or shifts to the opposite side do not accurately describe the anatomical and functional changes that occur in the sacrum during this specific movement.
