In mechanical spinal traction for C5-C7, the cervical spine should be positioned at:

• A. 25 - 30 degrees
• B. 0 degrees
• C. 15 - 20 degrees
• D. 45 - 60 degrees

Answer: (A)

In mechanical cervical traction, the angle of neck flexion changes which cervical levels receive the most distraction. For targeting the lower cervical spine, particularly C5-C7, about 25-30 degrees of neck flexion positions the traction line to effectively separate the lower segments while keeping the upper segments less affected. This degree of flexion opens the spaces and foramina at those levels, helping relieve nerve root compression and disc/facet irritation there. Other angles bias to different regions: near neutral (0 degrees) mainly affects upper cervical levels; mild flexion (around 15-20 degrees) targets mid-cervical segments; and excessive flexion (45-60 degrees) isn’t typically used for C5-C7 due to discomfort and potential facet or soft tissue strain. Therefore, 25-30 degrees is the best choice to specifically treat C5-C7.
