Facet joint arthropathy, sometimes called facet osteoarthritis or facet syndrome, is a degenerative joint condition of the spine’s facet (zygapophyseal) joints. As the cartilage lining these synovial joints wears away over time, the joint surfaces become rough, leading to pain, stiffness, and reduced spinal mobility. This condition most often affects the lumbar region but can occur in the cervical and thoracic spine as well, with prevalence increasing markedly after age 50 RadiopaediaWikipedia.
Anatomy of the Facet Joint
Structure and Location
Facet joints are paired, synovial—plane joints located along the posterior aspect of each spinal motion segment. Each joint forms where the inferior articular process of one vertebra meets the superior articular process of the vertebra below. They occur at every level from C2–C3 down to L5–S1, providing stability and guiding movement of the vertebral column RadsourceWikipedia.
Articular Components (Origin and Insertion)
The bony “origin” and “insertion” of these joints are intrinsic to the vertebrae themselves: the superior articular process of the lower vertebra articulates with the inferior articular process of the vertebra above. A fibrous capsule envelops each joint, attaching around the margins of the articular surfaces, and a synovial membrane lines the inner surface to secrete lubricating fluid PMCRadsource.
Blood Supply
Arterial branches to the facet joints arise from the posterior spinal branches of the segmental arteries:
Cervical region: ascending cervical artery
Thoracic region: posterior intercostal arteries
Lumbar region: lumbar arteries
Venous drainage occurs via spinal and basivertebral veins into the internal and external vertebral venous plexuses Home.
Nerve Supply
Each facet joint is dually innervated by medial branches of the dorsal (posterior) rami at the same and the level above. Exceptions in the cervical spine include:
C2–C3 joint: third occipital nerve + C3 medial branch
C7–T1 joint: C7 + C8 medial branches
These small articular branches carry sensory fibers that transmit pain signals when the joint is inflamed or degenerated Wikipedia.
Functions
Facet joints serve six primary roles:
Guide flexion and extension of the spine
Limit excessive rotation and anterior shear forces
Provide stability and alignment for vertebral segments
Share axial load with intervertebral discs
Protect neural elements by maintaining foraminal dimensions
Contribute to proprioception, helping the body sense spinal position Wikipedia.
Types of Facet Joint Arthropathy
Facet arthropathy can be classified by region or by radiologic severity:
By Spinal Region
Cervical facet arthropathy (neck)
Thoracic facet arthropathy (mid-back)
Lumbar facet arthropathy (lower back) Radiopaedia
By Severity (Weishaupt Grading System)
Grade I: Mild joint space narrowing, small osteophytes
Grade II: Moderate narrowing, small-to-moderate osteophytes
Grade III: Severe narrowing, moderate osteophytes, subchondral sclerosis
Grade IV: Ankylosis, large osteophytes, joint deformation Radiopaedia.
Types of Facet Joint Arthropathy
Cervical Facet Arthropathy: Degeneration of facet joints in the neck (C2–C7) causing neck pain, headaches, and sometimes arm pain when inflamed Medscape.
Thoracic Facet Arthropathy: Less common, affecting mid-back facets (T1–T12), often causing local thoracic pain worsened by twisting and extension Spine Connection.
Lumbar Facet Arthropathy: The most frequent type, involving lower back facets (L1–S1), leading to chronic low back pain aggravated by standing or arching backward NCBI.
