The application of a cervical collar on a trauma victim can cause more harm to the patient, leading to secondary injuries or even death, according to experts at Baylor College of Medicine in a study that appears in the current online edition of the Journal of Trauma . "Cervical extrication collars are put on about 15 million times a year in the United States alone by emergency medical personnel or doctors in hospitals to protect the cervical spine in case of a bad injury. It is known that after a person has a bad injury, you can create a secondary injury very easily," said Dr. John Hipp , assistant professor of orthopedic surgery at BCM and senior author of the paper. "We have discovered that the cervical collar, in the case of a really bad injury, not only doesn't protect the spine but can actually make things a lot worse."
