What is the normal range for cervical spine rotation?

• A. 0-70°
• B. 0-30°
• C. 0-50°
• D. 0-90°

Answer: (A)

Rotation of the cervical spine refers to turning the head from side to side around a vertical axis, with the upper joints (C1–C2) contributing most of this motion. In healthy adults, the end range of rotation to a single side is typically about 60–70 degrees, with 70 degrees commonly cited as the upper limit. That’s why 0 to 70 degrees on one side is the best match for normal cervical rotation. Values like 0–30° or 0–50° are more limited than normal, while 0–90° would exceed the typical one‑side limit. (Total rotation in both directions would be greater, but the common reference for a single side is about 70 degrees.)
