Cervical Spine — C1 through C7
Your neck.
Seven vertebrae carrying the full weight of your head — and, in service, the weight of a helmet, night vision mount, and counterweight on top of it. The cervical spine has the largest range of motion of any region, which is exactly why it wears out. Nerve roots exiting C5 through C8 run into your shoulders, arms and hands.
How it is rated
Rated on the General Rating Formula using CERVICAL range of motion — normal forward flexion is 45 degrees, normal combined range of motion is 340 degrees.
Codes that live here
- Cervical Strain — DC 5237
- Cervical Degenerative Disc Disease — DC 5242
- Cervical Radiculopathy — secondary, rated on the nerve
What causes it in service
Carrying heavy gear, helmet and headgear load, repetitive overhead work, vehicle rollovers, parachute landings, blast exposure, and years of rucking with a loaded pack pulling the shoulders forward.
