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.
[10] Isthmic anterolisthesis (also called type 2) is caused by a defect in the pars interarticularis (spondylolysis) but it can also be seen with an elongated pars. [11] [12] Degenerative anterolisthesis (also called type 3) is a disease of the older adult that develops as a result of facet arthritis and joint remodeling.
These cannot be determined by plain films, as the x-ray passes through the soft tissue. A study by Giles et al., stated that sixteen of the thirty patients (53%) had retrolisthesis of L5 on S1 ranging from 2–9 mm; these patients had either intervertebral disc bulging or protrusion on CT examination ranging from 3–7 mm into the spinal canal.
The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints (facet syndrome). If severe, it may cause pressure on the spinal cord or nerve roots with subsequent sensory or motor disturbances, such as pain , paresthesia , imbalance , and muscle weakness in the limbs.
This results in spinal instability and more degenerative changes in spinal structures including facet joints, ligamentum flavum, and intervertebral discs. These pathologic changes result in narrowing of the vertebral canal and neurovascular compression at the lumbosacral nerve roots .
Degenerative disc disease (DDD) is a medical condition typically brought on by the aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the spine. [1] DDD can take place with or without symptoms, but is typically identified once symptoms arise.
Forward displacement of a proximal vertebra in relation to its adjacent vertebra in association with an intact neural arch, and in the presence of degenerative changes, is known as degenerative spondylolisthesis, [9] [10] which narrows the spinal canal, and symptoms of spinal stenosis are common. Of these, neural claudication is most common.
The vast majority of spondylolysis occur in the lumbar vertebrae, however it can also be seen in cervical vertebrae. [2] The lumbar vertebra consist of a body, pedicle, lamina, pars interarticularis, transverse process, spinous process and superior and inferior articular facets, which form joints that link the vertebrae together. When examining ...
