A cervical collar, also known as a neck brace, is a medical device designed to support and immobilize the neck following an injury or during recovery from certain medical conditions. Made of rigid or semi-rigid materials like foam, plastic, or metal, they come in various sizes to fit different neck circumferences and injury severities.

Cervical collars restrict neck movement to prevent further injury or damage to the spinal cord and surrounding tissues. They’re commonly used for neck sprains, whiplash injuries, cervical fractures, or post-surgical recovery.
