During mechanical spinal traction for the atlantoaxial joint, what cervical spine position is recommended?

• A. 0-5 degrees of cervical flexion
• B. 20-30 degrees of cervical flexion
• C. Neutral neck position
• D. 0-5 degrees of cervical extension

Answer: (A)

For upper cervical traction, the position of the head matters because the angle of the neck determines which cervical segments are loaded by the traction force. To target the atlas–axis (upper cervical) joints effectively, you want the neck near neutral with only a small amount of flexion. About 0 to 5 degrees of flexion aligns the pull along the spinal axis to gently distract C1 from C2 without dragging the force into the lower cervical segments.

Too much flexion (like 20–30 degrees) shifts the traction vector toward the mid to lower cervical levels, so it’s not ideal for the atlantoaxial joint. A completely neutral position offers less optimal alignment for isolating C1–C2 distraction. Extension is not favored because it changes the orientation away from the upper cervical joints and can increase loading on other structures or produce less effective distraction at the atlas–axis.

So, a near-neutral head position with only a small amount of flexion best targets the atlantoaxial joint during mechanical traction.
