Arthritis (Spinal Osteoarthritis)
What is arthritis in the back?
In general, osteoarthritis is a condition in which the protective cartilage that cushions the tops of bones degenerates, or wears down. This causes swelling and pain. It may also cause the development of osteophytes, or bone spurs.
What causes arthritis in the back?
In general, osteoarthritis happens as people get older. As we age, the disks in the spine lose height and begin to bulge. They also lose water content and begin to dry out and weaken. This problem causes settling, or collapse, of the disk spaces and loss of disk space height.
As the facet joints experience increased pressure, they also begin to degenerate and develop arthritis, similar to what may occur in the hip or knee joint. The smooth, slippery articular cartilage that covers and protects the joints wears away.
