Facet joint pain is a common mechanical, nociceptive source of back pain, but it can be difficult to diagnose with certainty. Symptoms typically consist of localized axial pain that may radiate in a non-dermatomal pattern, often without clear neurologic findings. Management is usually non-surgical and may include medications, targeted injections, and diagnostic or therapeutic nerve blocks.
Facet joints are a significant source of back pain, with reviews estimating them as the primary pain generator in approximately 10โ15% of young adults and up to 45% of older adults. In patients with chronic low back pain, prevalence estimates range from 27โ40%. Reporting universal facet joint osteoarthritis in a cadaveric study of 647 specimens.
Demonstrated that the prevalence of facet joint osteoarthritis increases steadily with age, reaching approximately 89% in individuals over 60 years old. Facet joint pain most commonly arises from degenerative processes, representing the most frequent etiology. This degeneration occurs along a continuum that includes joint space narrowing, loss of synovial fluid, cartilage degeneration, and bony overgrowth, with pain thought to result primarily from inflammation of surrounding tissues as the joint space collapses.
Synovial cysts may also develop and further exacerbate symptoms. Another important cause is spondylolisthesis, which is generally associated with degeneration and loss of normal facet joint range of motion, potentially leading to facet subluxation. While often degenerative, spondylolisthesis-related facet pain may also result from congenital abnormalities, acute or stress-related fractures, or isthmic spondylolisthesis.
The zygapophyseal (facet) joints are small synovial joints located between the superior and inferior articular processes of adjacent vertebrae, forming the posterolateral articulations of the spine. They extend from C2 to S1 and exhibit regional anatomic variability, providing both spinal stability and controlled motion. As the only true synovial joints of the spine, they contain hyaline cartilage, subchondral bone, a synovial membrane, and a joint capsule.
If you are experiencing symptoms that may be related to facet joint pain, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
