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.
Relative stenosis is said to exist when the anterior-posterior canal diameter measures between 10 and 13 mm. Absolute stenosis of the lumbar canal exists anatomically when the anterior-posterior measurement is 10 mm or less. [12] [13] [14] Plain X-rays of the lumbar or cervical spine may or may not show spinal stenosis.

[1] While some medical dictionaries define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it (or the sacrum), [2] [3] it is often defined in medical textbooks as displacement in any direction.
In a study of 146 patients with lumbar spinal stenosis (mean age, 68 years, 42% women) who did not undergo surgery, followed up for 3 years, the study reported that approximately one-third of participants indicated improvement; approximately 50% reported no change in symptoms; and approximately 10% to 20% of patients condition worsened.
Facet joint arthrosis is an intervertebral disc disorder. The facet joints or zygapophyseal joints are synovial cartilage covered joints that limit the movement of ...
Despite this, the use of imaging in low back pain has increased. [10] Some low back pain is caused by damaged intervertebral discs, and the straight leg raise test is useful to identify this cause. [5] In those with chronic pain, the pain processing system may malfunction, causing large amounts of pain in response to non-serious events. [11]
There is also spondylosis of the facet joint between C2 and C3, with some foraminal stenosis at this level (upper arrow), which appears to be asymptomatic. Signs and Symptoms. Radiculopathy is a diagnosis commonly made by physicians in primary care specialties, orthopedics, physiatry, and neurology.
