For a patient who appears to prefer supination of the arm, how should HVLA be applied to treat the radial head?

• A. Supinate the Arm to the Restrictive Barrier and Thrust Through It
• B. Pronate the Arm to the Restrictive Barrier and Thrust Through It
• C. Extend the Elbow and Apply Traction
• D. Abduct the Shoulder and Twist the Forearm

Answer: (B)

When evaluating a radial head dysfunction, the key idea is to use HVLA in the direction of the restrictive barrier. If the patient shows a preference for supination, their motion is most restricted in pronation. So you bring the forearm into pronation up to the restrictive barrier and deliver a quick, but focused, thrust through that barrier. This releases the stuck radial head and restores motion. Moving the forearm into further supination would push away from the barrier and is unlikely to release the restriction. Extending the elbow with traction or abducting the shoulder and twisting the forearm aren’t aligned with the radial head HVLA approach for this pattern.
