Arthritis of the Spine
Spinal arthritis occurs in the facet joints (also called vertebral joints). These joints connect vertebrae together and are located in the posterior (rear) portion of the spine.
Facet Joint Syndrome
Facet syndrome is a syndrome in which the zygapophysial joints (synovial diarthroses, from C2 to S1) cause back pain.55% of facet syndrome cases occur in cervical vertebrae, and 31% in lumbar. Facet syndrome can progress to spinal osteoarthritis, which is known as spondylosis. Pathology of the C1-C2 (atlantoaxial) joint, the most mobile of all vertebral segments, accounts for 4% of all spondylosis.
