Facet Joint Syndrome

Facet syndrome is a condition in which the Zygapophysial joint in the back of the spine degenerate and subsequently cause pain.

The facet joints are found at every level on both sides of the lumbar spine. They provide about 20 percent of the twisting stability in the low back. Each facet joint is positioned at each level of the spine to provide the needed support especially with rotation.

Facet joints also prevent each vertebra from slipping over the one below. A small capsule surrounds each facet joint providing a nourishing lubricant for the joint.

Also, each joint has a rich supply of tiny nerve fibers that provide a painful stimulus when the joint is injured or irritated. Inflamed facets can cause a powerful muscle spasm.

Facet Syndrome is a common cause of low back pain. It is a low back pain syndrome attributed to osteoarthritis of the interarticular vertebrae; Clinical Low back pain that increases on extension, radiates to the posterior thigh, and ends at the knee; x-ray and CT imaging reveal narrowing of disk space, osteophyte formation.
