This is called fluoroscopy. It is a very high dose of x-ray radiation so it should be considered carefully. The injury in the YouTube is extreme and life threatening. It is similar to a cranial dislocation or basilar skull fracture like what killed Dale Earnhardt when it happens between C-1 and the skull.

If the tear is complete, it requires surgery to stabilize. If it is not complete, with proper support and posture, especially when sleeping or resting, it can slowly heal over 6 weeks time or more. It still may require surgery if the tear is large.

roffa, How is your dislocation being treated ?
