Which statement correctly describes the cervical halo orthosis?

• A. Attaches to skull by screws
• B. Uses a forehead band without screws
• C. Full restriction of all CxSp motion
• D. Pt will wear halo until spine becomes stable

Answer: (A)

A cervical halo orthosis immobilizes the head and upper neck by anchoring a halo ring to the skull with pins that are screwed into the outer skull bone. This skull-based fixation is the defining feature, with a vest or body collar connected to the halo to keep the cervical spine stable. That makes the correct statement the best choice: the device attaches to the skull by screws (pins). It does not rely on a forehead band, and while it provides rigid immobilization of the head and upper cervical spine, it does not guarantee complete restriction of all cervical motion in every direction. The duration of wear varies and is determined by healing and stability, not an automatic lifelong requirement.
