Cervical Spinal Stenosis
Spinal canal narrowing in the neck that can compress the spinal cord
ICD-10: M48.02 · cervical condition
Cervical spinal stenosis is a narrowing of the spinal canal in the neck (cervical spine). When this narrowing compresses the spinal cord itself — a condition called cervical myelopathy — it can cause serious symptoms affecting balance, hand coordination, and even bowel or bladder function. When only nerve roots are affected, the result is cervical radiculopathy (arm pain and numbness). Early diagnosis and specialist evaluation are important.
Symptoms
- Neck pain and stiffness
- Pain, numbness, or tingling radiating into the shoulder, arm, or hand
- Hand weakness or clumsiness (difficulty with buttons, writing, or gripping)
- Problems with balance or gait — feeling unsteady while walking
- Heavy or weak feeling in the legs
- Electric shock sensation down the back with neck flexion (Lhermitte's sign)
- Bladder urgency or difficulty (in myelopathy cases)
Causes & Risk Factors
- Degenerative disc disease and bone spur formation narrowing the cervical canal
- Herniated cervical discs compressing the cord or nerve roots
- Thickening of the posterior longitudinal ligament (OPLL)
- Congenitally narrow spinal canal (increases vulnerability)
- Rheumatoid arthritis affecting cervical joints
- Neck trauma or prior surgery
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
- T2-weighted axial sequences show obliteration of the CSF space (bright signal) around the spinal cord at stenotic levels; cord signal change (T2 hyperintensity) indicates myelopathic involvement
- Thickened ligamentum flavum (>3-4 mm on axial MRI) is the most common posterior contributor to cervical stenosis in older adults
- Disc osteophyte complexes and uncovertebral joint hypertrophy contribute to foraminal or lateral recess narrowing at individual levels
- MRI is the preferred modality due to superior soft-tissue contrast for cord, disc, and ligament evaluation; results vary by individual and require specialist interpretation
CT Scan
- CT myelogram provides excellent bone detail and, with contrast, can delineate nerve root and cord compression when MRI is contraindicated or inconclusive
- Calcification of the posterior longitudinal ligament (OPLL) — a significant contributor to cervical stenosis in some populations — is best characterised on CT
- Canal diameter measurement on axial CT: values <10 mm are associated with symptomatic stenosis
X-Ray
- Lateral cervical radiograph may show disc height loss, osteophyte formation, or kyphotic alignment associated with spondylotic stenosis
- Dynamic flexion-extension views assess segmental instability that may worsen stenosis in certain positions
- Plain films cannot directly visualise canal dimensions or cord/nerve root involvement — MRI is required for diagnosis
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
50-70 years; degenerative cervical stenosis increases sharply in prevalence after age 50 as disc and facet degeneration accumulate
Gender Distribution
Men affected approximately 1.5 to 2 times more often than women for symptomatic degenerative cervical myelopathy
Estimated Prevalence
Degenerative cervical myelopathy — the most common presentation of cervical stenosis — has an estimated prevalence of 20-100 per 100,000 population; it is the leading cause of spinal cord dysfunction in adults in the developed world; based on published population studies, individual presentation varies
Treatment Options
Conservative
- Physical therapy with careful cervical stabilization exercises
- Anti-inflammatory medications and muscle relaxants
- Cervical epidural steroid injections for radiculopathy
- Soft cervical collar for short-term symptom relief
- Activity modification to avoid neck hyperextension
Surgical
- Anterior cervical discectomy and fusion (ACDF) — the most common approach
- Cervical disc arthroplasty (disc replacement) — motion-preserving alternative to ACDF
- Posterior cervical laminectomy and fusion — for multi-level disease
- Cervical laminoplasty — expands the canal while preserving motion
When to see a spine specialist
Cervical myelopathy (spinal cord compression) requires prompt specialist evaluation. If you have hand clumsiness, balance problems, or weakness in the legs alongside neck symptoms, see a spine specialist or neurosurgeon urgently.

Questions to Ask Your Doctor
Bring these questions to your next appointment about cervical spinal stenosis.
- 1
Which part of my cervical canal is narrowed — the central canal, the lateral recess, or the foramen — and does that affect which treatment is most appropriate?
- 2
Is my stenosis primarily from soft-tissue causes (disc herniation, thickened ligament) or bony causes (osteophytes, facet hypertrophy), and does the distinction change my options?
- 3
What are the early signs that my stenosis is progressing to myelopathy (spinal cord compression), and how would we monitor for that?
- 4
How long should I pursue conservative care before reconsidering surgical decompression — and what specific functional benchmarks would guide that decision?
- 5
If surgery is recommended, what approach (anterior vs. posterior) is preferred for my anatomy, and what are the risks and expected recovery timeline?

Frequently Asked Questions
How do doctors diagnose cervical stenosis?
Diagnosis begins with a physical exam assessing reflexes, strength, and coordination. An MRI of the cervical spine is the gold standard for visualizing cord or nerve compression. A CT myelogram may be used in patients who cannot have MRI (e.g., pacemaker). Nerve conduction studies can help differentiate nerve root from spinal cord involvement.
What is cervical myelopathy and why is it serious?
Cervical myelopathy occurs when the spinal cord is compressed by narrowing in the neck. Unlike nerve root compression, which is painful but usually reversible, spinal cord compression can cause permanent neurological damage if untreated. Symptoms include hand clumsiness, balance problems, and leg weakness. Early surgical decompression typically stops progression and can allow partial recovery.
Is ACDF surgery safe?
ACDF is one of the most commonly performed spine procedures and has a well-established safety profile. Major complication rates are low (1–2%). The procedure typically takes 1–2 hours and most patients go home the same day or after one night. Most people return to desk work within 2–3 weeks and physical jobs within 6–12 weeks.
