Degenerative Disc Disease
Degenerative disc disease is a condition where the intervertebral disc, the gel-like material between the vertebrae, has begun to wear out due to aging, repetitive stress, smoking, injury, formation of bone spurs or obesity.
The bones in the spinal column called vertebrae surround the spinal cord and other nerves, and are cushioned by soft intervertebral discs that act as shock absorbers for the spine. The intervertebral discs are composed of a jelly-like nucleus pulposus at the center, surrounded by a fibrous ring called the annulus fibrosus.
The discs between our vertebrae contain a lubricating fluid which cushions the discs and helps to hold them in place. As age advances, the amount of fluid decreases causing the discs to move out of position, a condition referred to as a bulging disc. A bulging disc puts pressure on the spinal nerves causing pain in the affected region. Bulging discs can occur at any point on the spine but they are most common in the lower back (lumbar region).
Low Back Pain
Low back pain is the pain felt in the lower back that may originate from muscles, nerves, bones, joints or other structures in the spine. Low back pain is one of the most common medical problems experienced by most people at some time in their life. People with low back pain may have difficulty to perform everyday activities. Low back pain can be acute usually lasting from few days to few weeks, or chronic lasting for more than three months.
Facet joints, also called zygapophyseal joints, are located at the back of the spine which connects the vertebrae together. There are two joints between each pair of vertebrae located on either side of the spine. The facet joints provide stability for the spine.
