If the lumbar intervertebral disc is black if it is ischemic in the lumbar area due to pathological factors, the blood supply can be restored through surgery and other means, and it can usually be recovered; if it is degenerative changes, it is more difficult to recover. Lumbar disc blackening does not mean that the disc becomes black under the naked eye, but refers to the fact that on the MRI image, or on the MRI T2 image, the normal disc contains a certain amount of water, which is shown as white (high signal), and when the disc has a low water content, it is darker and can be gray or black (low signal), which is called disc blackening. There are many reasons for low water content in the lumbar discs, such as ischemia in the lumbar spine, cystic changes within the bone, and degenerative changes in the lumbar discs. If the lumbar spine ischemia, such as lumbar spine fracture, through surgical incision and reset, internal fixation, etc., can restore the lumbar spine blood supply, so that the “blackened” discs to recover; if it is a degenerative change in the intervertebral discs, such as lumbar disc herniation, it is generally difficult to recover. Lumbar intervertebral disc black, it is recommended to consult a doctor in time to clarify the diagnosis, under the guidance of the doctor for targeted treatment.
