What is a facet or zygopophysial joint?
Facet joint or zygapophysial joint is a joint that connects two adjacent vertebral bodies. A facet joint is present on both right & left side between two adjacent vertebral bodies in the spine. Facet joints are formed by the inferior & superior articular processes of the adjacent vertebral bodies. These joints allow the spine to bend and twist, and they keep the back from slipping too far forward or twisting without limits. Each joint gets its sensation from nerves called Medial Branches at the same level and the level above. Breakdown or degeneration of these joints can lead to neck pain, back pain, arm pain or leg pain when the joint is injured or irritated leading to a diagnosis of facet joint disease.
What causes facet joint disease or arthritis?
Facet joint disease is commonly caused by years of repetitive strain, intervertebral disc degeneration and minor trauma. Facet joint disease can also rarely be caused by whiplash injury caused by motor vehicle accidents and spine injury. Facet syndrome can progress to spinal osteoarthritis, which is known as spondylosis.
