The purpose of a collar is to prevent ranges of motion outside of limits deemed unfavorable for fracture healing.
A fracture that is deemed to be stable may be treated with a collar immobilization or without immobilization.
Early mobilization is instituted once a patient is upright. AP lateral plain x-rays are then obtained to make sure there is no significant fracture displacement requiring surgery.
