Re: Vacuum Disc Phenomenon in the spinal disc
Vacuum sign in the disc is a sign of drying, deterioration and aging of the disc. It can be accompanied by back pain if the drying out is sufficient to cause the disc to shrink and flatten, which slightly displaces the vertebrae. It would be good to look at the discs showing the vacuum sign and compare the height of them to the height of the normal ones. This degenerative process in the disc occurs over many years and can be associated with other arthritic processes such as bone spur formation, which can eventually press on nerves. Findings on xray often do not correlate well with symptoms. It is possible to have xray findings with no symptoms, and vice versa.
