Facet joint arthrosis is an intervertebral disc disorder.The facet joints or zygapophyseal joints are synovial cartilage covered joints that limit the movement of the spine and preserve segmental stability.
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.
The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.
The CDC (Centers for Disease Control and Prevention) reported that 18.9 percent of American adults had been diagnosed with any type of arthritis, a common cause of joint pain, in 2022.
The articular process or zygapophysis (Greek: ζυγόν, romanized: zugón, lit. 'yoke' + apophysis) of a vertebra is a projection of the vertebra that serves the purpose of fitting with an adjacent vertebra.
Essential to remember is that the pattern of referred pain in no way hints at the spinal level involved. Multiple studies confirm that there is considerable overlap in the distribution of pain stemming from the zygapophyseal joints, including anterior, lateral or posterior thigh, groin, lumbar spine region, and trochanter region.
The disease is not fatal; however, some associated complications can lead to death. Complications may include paralysis, dysphagia (difficulty swallowing), and lung infections. Although DISH manifests in a similar manner to ankylosing spondylitis, they are separate diseases. Ankylosing spondylitis is a genetic disease with identifiable marks ...
