Innominate rotations can be classified as which, and what treatment is used to restore symmetry?

• A. Innominate rotations can be anterior or posterior; treatment uses MET or HVLA to restore symmetry and motion at the ilium
• B. Innominate rotations can be superior or inferior; treatment uses stretching
• C. Innominate rotations can be medial or lateral; treatment uses HVLA only
• D. Innominate rotations are fixed and do not require manipulation

Answer: (A)

An innominate rotation is categorized by the direction the ilium rotates relative to the sacrum—anteriorly or posteriorly. This rotation creates asymmetry in the pelvic ring that can affect gait and low back mechanics. To restore symmetry, the usual approaches combine techniques that encourage the pelvis to realign using the patient’s own muscle effort or a controlled corrective impulse. Muscle Energy Technique engages the patient in precise muscle contractions against a counterforce to lengthen tight muscles and guide the ilium back toward neutral, rebalancing the pelvis. High-velocity, low-amplitude manipulation delivers a quick, targeted thrust to realign the ilium with the sacrum and restore proper motion at the iliosacral joints. These methods address the dynamic rotational nature of the fault, rather than treating it as a fixed structure.
