What are spinal facets?

What does facet mean in anatomy?

What is a facet joint nerve?
Facet joints are surrounded by a joint capsule made up of synovial membrane tissue. This joint capsule contains a rich innervation of nerves and its upper pad is typically fused with the fatty sheath of the spinal nerve. 1. See Cervical, Thoracic and Lumbar Facet Joint Injections.
What are the four curvatures of the vertebral column?
There are four natural curves in the spinal column. The cervical, thoracic, lumbar, and sacral curvature.
Are facet joints synovial?
facet joint capsule – Like other synovial joints in the body, they are surrounded by a capsule of connective tissue that produces synovial fluid to nourish and lubricate the joint.
What causes facet hypertrophy?
Facet Hypertrophy: Causes Osteoarthritis and overloading of the joint are the most common causes of facet hypertrophy. The most common cause of overloading is degenerative disc disease, which causes the disc height to shrink and consequently the bony components of the facet joint to place increasing pressure on each other.
What is facet hypertrophic disease?
Hypertrophic Facet Disease Definition. Facet Hypertrophy is the term used to describe a degeneration and enlargement of the facet joints. The facet joints, which are a pair of small joints at each level along the back of the spine, are designed to provide support, stability, and flexibility to the spine.
What are symptoms of Facet joint injury?
Symptoms of a facet joint injury include: The sudden onset of lumbar or cervical pain. There can be point tenderness at the site of the inflamed facet joints and there is often “guarding,” which is a loss of mobility due to a lack of spinal muscle flexibility in the affected area.
What is facet syndrome?
Facet syndrome. Jump to navigation Jump to search. Facet syndrome is a syndrome in which the facet joints (synovial diarthroses, from C2 to S1) cause painful symptoms.
