Spinal Arthritis
Degenerative joint disease of the spine — the most common cause of chronic back pain in adults
ICD-10: M47.9 · systemic condition
Spinal arthritis refers to the degeneration of the facet joints — the small synovial joints that link adjacent vertebrae — and encompasses the same pathological process as osteoarthritis in the hip or knee, applied to the posterior spine. As cartilage wears and joint space narrows, bone spurs form, joints enlarge, and the surrounding structures become inflamed. Spinal arthritis is extremely common: it affects the majority of adults over 60 to some degree and is the leading cause of chronic axial back and neck pain in this age group. It is distinct from inflammatory arthritis (such as rheumatoid arthritis or ankylosing spondylitis), which has an autoimmune basis. Most spinal arthritis is mechanical and degenerative.
Symptoms
- Morning stiffness and aching in the neck or lower back that loosens with movement (classic facet joint pattern)
- Pain worse with prolonged standing, walking, or spinal extension
- Cracking, grinding, or popping sensations with spinal movement (crepitus)
- Localized tenderness directly over the spine or facet joints (lateral to midline)
- Pain that may radiate into the buttocks or upper thighs but typically not below the knee
- Symptoms that worsen in cold or damp weather or after periods of inactivity
Causes & Risk Factors
- Aging — the universal driver of facet joint cartilage loss and osteophyte formation
- Prior spinal injury or surgery accelerating local degeneration at affected levels
- Obesity — increases posterior joint loading and accelerates wear
- Inflammatory arthropathies (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis) involving facet joints
- Repetitive occupational loading or high-impact sport over decades
- Genetic predisposition to cartilage breakdown
Imaging Findings
Imaging studies are commonly used to identify findings associated with this condition. Results vary by individual; a qualified spine specialist interprets findings in the context of a full clinical evaluation.
MRI
- Facet joint cartilage loss with joint space narrowing on fat-saturated sequences
- Periarticular bone marrow edema indicating active inflammation (STIR or fat-sat T2)
- Osteophyte formation at the superior and inferior articular processes
- Ligamentum flavum hypertrophy from chronic facet joint stress
- Note: Degenerative facet changes are nearly universal by age 70 — clinical correlation determines whether imaging findings are the pain source
CT Scan
- Articular surface erosion, joint space narrowing, and subchondral sclerosis
- Osteophyte formation at articular margins
- Gas within the facet joint (vacuum phenomenon) in advanced degeneration
- Facet joint subluxation may accompany severe arthritis
X-Ray
- Facet joint space narrowing most visible on oblique lumbar views
- Sclerosis of the articular surfaces
- Osteophytic lipping at the articular processes
- Disc space narrowing commonly co-existing at the same levels
Who Is Commonly Affected
The following patterns are commonly associated with this condition based on published population studies. Individual presentation varies; these figures are informational only.
Peak Age Range
55–75 years
Gender Distribution
Roughly equal, though females may have more symptomatic presentation
Estimated Prevalence
Radiographic evidence of facet OA in approximately 40% of adults over 50; nearly universal (>80%) in adults over 70
Treatment Options
Conservative
- Low-impact aerobic exercise (swimming, cycling, walking) to maintain joint mobility and reduce pain
- Physical therapy targeting core strengthening, postural correction, and facet joint mobility
- NSAIDs and topical anti-inflammatory medications for pain flares
- Medial branch nerve block injections — diagnose and temporarily treat facet-mediated pain
- Heat therapy and transcutaneous electrical nerve stimulation (TENS)
- Weight loss to reduce posterior spinal loading
Surgical
- Radiofrequency ablation (neurotomy) of medial branch nerves — provides 6–18 months of relief for confirmed facet-mediated pain
- Decompressive laminectomy if severe arthritic overgrowth causes central or foraminal stenosis with neurological symptoms
- Spinal fusion for instability caused by advanced facet destruction — reserved for refractory cases
When to see a spine specialist
See a spine specialist if axial back or neck pain has persisted beyond 6–8 weeks without improvement, significantly limits daily activity, or is accompanied by leg or arm symptoms suggesting nerve involvement. If you have been diagnosed with spinal arthritis and develop new or worsening neurological symptoms (leg weakness, foot drop, arm weakness), seek prompt evaluation.

Questions to Ask Your Doctor
Bring these questions to your next appointment about spinal arthritis.
- 1
Which spinal levels show the most significant arthritic changes, and do they correlate with my pain location?
- 2
Is my morning stiffness improving within 30 minutes — which suggests mechanical OA — or lasting longer, which might suggest inflammatory arthritis?
- 3
What is the role of anti-inflammatory medications versus physical therapy for my degree of spinal arthritis?
- 4
Would facet joint injections or medial branch blocks provide meaningful relief for my pattern of pain?
- 5
Are there systemic inflammatory markers — ESR, CRP, HLA-B27 — I should have checked given my symptoms?
Clinical Evidence
Frequently Asked Questions
Is spinal arthritis the same as degenerative disc disease?
They are related but distinct. Degenerative disc disease refers to breakdown of the intervertebral discs — the cushions between vertebrae — causing disc height loss, disc bulging, and eventual disc collapse. Spinal arthritis refers primarily to degeneration of the posterior facet joints. Both are part of the same degenerative cascade and often coexist, but they present differently: disc disease causes more flexion-related pain and radiculopathy; facet arthritis causes more extension-related axial pain without radiation below the knee.
Can spinal arthritis be reversed?
No — the structural changes of spinal arthritis (bone spur formation, cartilage loss, joint space narrowing) are permanent. However, symptoms can be managed effectively, and progression can be slowed. Weight loss, regular low-impact exercise, core strengthening, and anti-inflammatory measures reduce pain and stiffness. Many patients with significant spinal arthritis on imaging have minimal symptoms — the degree of degeneration does not directly correlate with pain severity.
What is the best exercise for spinal arthritis?
Low-impact aerobic exercise that keeps the joints moving without compressive loading — swimming, cycling, walking, and water aerobics are consistently the best-tolerated options. Core strengthening exercises (pelvic tilts, bridges, bird-dog) reduce the load on arthritic facet joints by improving muscular support. Avoid high-impact activities (running on hard surfaces, heavy lifting with poor form) that increase posterior joint stress. Regular movement is consistently better than rest for arthritis pain.
When does spinal arthritis need surgery?
The vast majority of spinal arthritis does not require surgery. Surgical intervention is considered when: (1) arthritic overgrowth causes significant spinal stenosis with neurological symptoms (leg weakness, loss of bladder control), (2) conservative care including injections and physical therapy has failed over 3–6 months, or (3) instability from advanced facet destruction causes mechanical pain refractory to all other measures. Radiofrequency ablation — a minimally invasive procedure, not traditional surgery — is often the bridge step between injections and open surgery.
