Dynamic would be something like DMX or a movement-based MRI where you’re moving around and they’re taking pictures. Obviously, a static image would be something like just a routine MRI where you’re lying face up and face up in a tube, and they go ahead and do your image. So, there are two types of imaging that can suggest cranial cervical instability. And that’s why this is so exciting.”īased on a new study looking at digital motion x-ray or DMX. “And so, the problem has always been trying to find a measurement that normal people don’t have at all. So, when we do things like Grabb-Oakes or Powers ratio or clivo-axial-angle, there’s some mixture there between patients who are totally normal and have no issues, but will have abnormal measurements, and patients who have Cranio-cervical instability who have abnormal measurements. So, one of the problems, however, with diagnosing Cranio-cervical instability that’s usually not talked about very often is that patients without CCI may also have similar measurements to patients with CCI. We’re going to really focus today more on the alar ligaments. And there’s lots of different ligaments up there. So, Cranio-cervical instability or also called “CCJ instability” means that the upper neck bones move around too much due to damaged or loose ligaments. And I’d like to introduce you to some interesting and really critical new data on Cranio-cervical instability diagnosis.
