A cervical collar is a medical device designed to support and immobilize the neck. It is often used after injuries, surgeries, or conditions affecting the cervical spine, which is the part of the spine located in the neck. The collar helps to prevent movement that could worsen an injury and aids in the healing process. Cervical collars come in various types, including soft collars and rigid collars. Soft collars provide gentle support and comfort, while rigid collars offer more stability and protection. Healthcare professionals may recommend a specific type based on the patient's condition and needs.
