Human Spine With Degenerative Disc Royalty-Free Stock Photography

Degenerative disc disease (DDD) is a type of arthritis that occurs when the spine's joints wear out. The discs in the spine, also known as intervertebral discs or spinal discs, act as shock absorbers between the vertebrae, which provide rigidity. As people age, the discs change shape and become less organized, and they lose proteoglycan, which affects their ability to bear weight.
