Degenerative disc disease overview
How spinal discs change over time
Intervertebral discs sit between the bones of the spine and act as cushions during movement. Over time, these discs naturally lose water content, become thinner and may lose some of their cushioning properties.
Although referred to as ‘degenerative disc disease’, it is not necessarily a disease. It commonly reflects age-related changes in the spinal discs, although some disc problems can also contribute to back or leg pain.
Degenerative disc disease symptoms
When disc degeneration becomes painful
Chronic disc degeneration is normal, and likely to be painless.
However, acute degeneration of a disc (disc prolapse or disc tear – links) can be acutely painful and may result in pressure on exiting major nerve roots. Most acute disc accidents resolve spontaneously over time, but some do require medical or surgical treatments.
Degenerative disc disease tests and diagnosis
When spinal imaging may be required
In most cases, expensive imaging is not needed, but if significant nerve root compression is suspected, MRI or CT scanning may need to be performed.
CT/MRI scans (this will reveal any other factors such as bone spurs – ‘osteophytes’, evidence of spinal stenosis, fracture or presence of tumours).
