Facet syndrome is a syndrome in which the facet joints (synovial diarthroses) cause painful symptoms. [1] In conjunction with degenerative disc disease , a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain.
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. In the event of hypertrophy of the vertebrae painful arthrosis can occur. [1]
Degenerative disc disease causes narrowing of the spaces. [27] Facet joints break down; Facet joints may hypertrophy [28] Compression fractures of the spine, which are common in osteoporosis [29] Synovial cysts form on the facet joints causing compression of the spinal sac of nerves (thecal sac)
In the more narrow sense, it refers to spinal osteoarthritis, the age-related degeneration of the spinal column, which is the most common cause of spondylosis. The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints (facet syndrome).
This definition reflects the current hypotheses for the pathophysiology of NC, which is thought to be related to the compression of lumbosacral nerve roots by surrounding structures, such as hypertrophied facet joints or ligamentum flavum, bone spurs, scar tissue, and bulging or herniated discs.
The facet and sacroiliac joints tend to be uninvolved. The thoracic spine is the most common level involved. [2] In the peripheral skeleton, DISH manifests as a calcific enthesopathy, with pathologic bone formation at sites where ligaments and tendons attach to bone.
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.
Causes: Spinal disc ... Inflammation of spinal tissue can then spread to adjacent facet joints and cause facet syndrome, ... hypertrophy) can affect the sciatic nerve
