Uncovertebral hypertrophy is bony overgrowth in the small joints at the sides of your neck vertebrae. It can squeeze a nerve root and cause neck pain, arm pain or numbness. Most cases improve with non-surgical care, and surgery is kept for severe or persistent nerve compression.
Quick note: This article is for education only. It is not medical advice. Your clinician should interpret your scan and symptoms.
What Is Uncovertebral Hypertrophy?
Your neck bones (cervical vertebrae) have small joints at their edges, called uncovertebral joints. "Hypertrophy" means that these joints have enlarged. Think of it as the spine's version of a door frame that has swollen shut.
The term often appears on MRI reports, which can sound alarming. The finding matters mainly when the growth narrows the openings where nerves exit the spine. Doctors call that narrowing cervical foraminal stenosis.
Why Does It Happen?
Uncovertebral hypertrophy is linked to degenerative change in the cervical spine. A neurosurgical case report describes it as a common cause of cervical radiculopathy from degenerative foraminal stenosis (PubMed Central). Radiculopathy simply means a compressed or irritated nerve root.
A study in Pain Physician reports that uncovertebral joint hypertrophy is considered a major cause of cervical neural foraminal stenosis. The same paper notes that the C5-6 level is a primary site (Mun et al., 2019).
Where it shows up most
- C5-6: a primary site of hypertrophy-related foraminal stenosis, per the 2019 Pain Physician paper.
- C6-7: also affected in the reported surgical case, alongside C5-6.
- One or both sides: MRI reports can describe different severity on the right and left.
Symptoms: What You Might Feel
Symptoms depend on which nerve root is squeezed. A spine surgeon writing on NeckandBack.com explains that C5-6 foraminal stenosis compresses the C6 nerve. That nerve supplies the biceps and the wrist extensors (Donald Corenman, MD, DC).
A clinician will match your symptoms to your scan. Many people with MRI changes feel little, so the picture always needs context.
Common signs of nerve root compression
- Neck pain that spreads into the arm
- Numbness or tingling in the arm or hand
- Weakness in muscles such as the biceps or wrist extensors
- Reduced grip strength in more advanced cases
Red flags: see urgent care
The spine information service Spine.co flags these symptoms as needing urgent care when neck pain comes with arm symptoms (Spine.co). Do not wait on them.
- Hand clumsiness or trouble with buttons
- Gait imbalance
- Loss of dexterity
- Symptoms in both arms
How Is It Diagnosed?
Diagnosis starts with your history and a physical exam. MRI shows the bony overgrowth and the nerve openings. In the surgical case report, MRI showed foraminal stenosis from severe hypertrophy, and nerve studies confirmed C6 and C7 radiculopathy (PubMed Central).
Imaging is also required before some treatments. StatPearls notes that MRI or CT should confirm the cause of symptoms before a cervical epidural injection (StatPearls).
Treatment Options, Step by Step
StatPearls says cervical radiculopathy should be treated in a stepwise fashion. It also states that over 85% of acute cases resolve without specific treatment within 8 to 12 weeks (StatPearls: Cervical Radiculopathy). That is reassuring, though your own timeline may differ.
| Step | What it involves | What the sources say |
|---|---|---|
| 1. Supportive care | Rest, activity changes, NSAIDs | NSAIDs for 1 to 2 weeks can relieve symptoms, per StatPearls. |
| 2. Physical therapy | Manual therapy, strengthening, sometimes traction | A case series found 10 of 11 patients improved at 6 months (Family Practice Inquiries, via MDedge). |
| 3. Medication adjuncts | Tricyclic antidepressants, gabapentin | StatPearls calls them useful adjuncts. |
| 4. Epidural steroid injection | Corticosteroid near the inflamed nerve | Often considered when conservative care fails after 6 to 8 weeks (StatPearls). |
| 5. Surgery | ACDF, sometimes with uncinatectomy | Used for advanced degeneration, including uncovertebral hypertrophy. |
Non-surgical care
- NSAIDs: StatPearls says inflammation is the key feature in nearly all cases. Some people must avoid certain NSAIDs, so ask your doctor.
- Physical therapy: No randomized trials of PT for cervical radiculopathy had been reported in the MDedge review. Even so, a case series showed benefit.
- Traction: Three randomized trials showed no advantage (two studies) or a modest one (one study) over placebo or standard PT, per the same review.
Injections
Epidural steroid injections target inflammation, not the bone. A Beacon Orthopaedics page says they do not "melt" arthritis. It cites a 60-70% chance of good to excellent results when combined with physical therapy (Beacon Orthopaedics).
An MDedge series of 32 patients who had failed conventional treatment reported a 62% "good or excellent" response at 14 days (MDedge). Spine.co adds that transforaminal cervical injections carry a higher complication profile than lumbar ones.
Surgery
Surgery is usually reserved for people who do not respond to conservative care, per the MDedge review. Anterior cervical discectomy and fusion (ACDF) can treat foraminal stenosis from advanced degeneration, including uncovertebral hypertrophy (PubMed Central).
Surgeons sometimes add a total uncinatectomy. This removes the overgrown uncinate process for fuller nerve decompression. A 2019 Acta Neurochirurgica report calls it a useful adjunct during ACDF (Clifton et al.). The approach is closely tied to the nearby vertebral artery, so it needs an experienced surgeon.
Surgery has risks. The MDedge review says it can improve pain and function but carries risks. Corenman also notes that decompression from behind is less effective when the compression comes from the front, as it does with uncovertebral hypertrophy.

When to See a Doctor
- Arm pain, numbness or weakness that persists
- Any red-flag symptom listed above
- Symptoms that worsen despite a few weeks of self-care
Frequently Asked Questions
Is uncovertebral hypertrophy the same as a slipped disc?
No. A disc herniation is soft disc material pressing on a nerve. Uncovertebral hypertrophy is bony enlargement of the joints beside the disc. Both can compress nerve roots.
Does it always cause pain?
Not necessarily. The finding matters when it narrows a nerve opening and your symptoms match. Your doctor decides if the scan explains how you feel.
Will I need surgery?
Probably not. StatPearls says over 85% of acute cervical radiculopathy resolves within 8 to 12 weeks without specific treatment. Surgery is considered when conservative care fails or nerve loss is significant.
Can bone spurs be removed?
In selected cases, yes. Surgeons can remove the uncinate process during ACDF to decompress the nerve. This is a specialist decision.
