Cervical Spine Questions 1. A patient arrived from the ER and the physician wants to best validate stability of the cervical spine. Which position(s) would be performed? Answer: Lateral flexion and extension 2. How many cervical vertebrae need to be visualized on the AP cervical image? Answer: C3–C7 3. If spinous processes are present on the oblique image and the intervertebral foramina are not open, what is the positioning error? Answer: Over-rotation 4. What is the positioning error if the right zygapophyseal joint is closed and the left zygapophyseal joint is open on an Open Mouth image? Answer: The patient’s head is tilted toward the right 5. When observing the Open Mouth image, the left C1–C2 joint is open while the right C1–C2 joint is closed. What is the positioning error? Answer: The patient’s head was tilted toward the right 6.
