Which cervical orthosis uses a forehead band without screws and provides maximum cervical motion control?

• A. Minerva orthosis
• B. Halo orthosis
• C. Four-poster orthosis
• D. Soft collar

Answer: (A)

The key idea is how the device anchors to the skull to limit movement. The Minerva orthosis uses a forehead band with a rigid skull-cap connection, creating a solid, immobile frame that restricts motion in all directions without any skull pins. That combination—forehead band plus a rigid head assembly—provides the strongest immobilization among non-pinned cervical orthoses, making it the best fit for maximum cervical motion control when screws are not used. In contrast, the halo uses skull pins (screws) for fixation, the four-poster relies on a frame attached differently (often to a bed), and a soft collar offers little restriction. Therefore, the forehead-band Minerva orthosis delivers the greatest control without screws.
