Cervical Myelopathy
Spinal cord compression in the neck that affects coordination, balance, and limb function
ICD-10: G99.2 · cervical condition
Cervical myelopathy is a condition in which the spinal cord is compressed in the neck (cervical spine), disrupting nerve signals between the brain and the rest of the body. Unlike a pinched nerve that causes localized arm pain, spinal cord compression can affect coordination, balance, hand function, and leg strength. It is the most common cause of spinal cord dysfunction in adults over 55 and tends to worsen progressively if untreated.
Classification
Mild Myelopathy (mJOA 15–17)
Common presentation at initial evaluationSubtle hand clumsiness, mild gait disturbance, hyperreflexia on examination; activities of daily living largely preserved. Watchful waiting with serial monitoring may be appropriate for stable mild disease.
Moderate Myelopathy (mJOA 12–14)
Common at time of diagnosisSignificant hand dysfunction affecting fine motor tasks, assistive device required for safe ambulation, or moderate difficulty with gait and balance. Surgical decompression is generally recommended to prevent further deterioration.
Severe Myelopathy (mJOA <12)
Less common; associated with poor prognosis without surgeryLoss of ambulatory ability, severe hand dysfunction, or sphincter involvement. Urgent surgical decompression is indicated; delay is associated with significantly worse neurological outcomes.
Symptoms
- Clumsy or weak hands — difficulty with fine motor tasks like buttoning a shirt
- Unsteady gait or balance problems
- Leg heaviness, stiffness, or weakness
- Numbness or tingling in the hands or arms
- Neck pain or stiffness (not always present)
- Bladder urgency or difficulty controlling urination in advanced cases
- Lhermitte's sign — electric shock sensation down the spine when bending the neck forward
Causes & Risk Factors
- Cervical spondylosis — age-related disc degeneration, bone spur formation, and ligament thickening that gradually narrows the spinal canal
- Large herniated disc in the neck pressing on the spinal cord
- Ossification of the posterior longitudinal ligament (OPLL) — a calcified ligament that encroaches on the canal
- Congenitally narrow spinal canal — some people have a smaller canal from birth, leaving less room before compression occurs
- Spinal instability or deformity resulting in cord impingement
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
- Spinal cord compression visible on T2-weighted sagittal sequences; canal diameter <10 mm correlates with severe myelopathy
- T2 intramedullary hyperintensity (bright signal within the cord) indicates existing cord injury and is a negative prognostic factor for post-surgical recovery
- T1 hypointensity within the cord indicates chronic myelomalacia — associated with poor neurological recovery
- Key measurements include anterior-posterior cord diameter, canal-to-cord ratio, and cross-sectional cord area; MRI is the gold standard
CT Scan
- Excellent for bony contributors to compression: osteophytes, OPLL (ossification of the posterior longitudinal ligament), and facet hypertrophy
- CT myelogram demonstrates cord deformation and CSF flow restriction, useful when MRI is contraindicated or hardware artifact is present
- Quantifies OPLL extent and thickness for surgical planning in OPLL-related myelopathy
X-Ray
- May show disc space narrowing, osteophytes, OPLL, or kyphotic deformity contributing to dynamic cord compression
- Flexion-extension lateral views assess cervical instability — important if fusion may be required alongside decompression
- Sagittal alignment (C2-C7 Cobb angle) measured on standing lateral films guides choice of surgical approach
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; the most common cause of spinal cord dysfunction in adults over 55 in the developed world
Gender Distribution
Men affected approximately 1.5 times more than women
Estimated Prevalence
Estimated prevalence ~20 per 100,000 population; degenerative cervical myelopathy (DCM) accounts for the vast majority of cases worldwide
Treatment Options
Conservative
- Watchful waiting with regular neurological monitoring — appropriate only for very mild, stable cases
- Physical therapy — to maintain strength and function, but does not treat the underlying compression
- Activity modification — avoiding high-impact or contact activities that risk falls or neck injury
- Cervical collar — occasionally used short-term to reduce motion and irritation
Surgical
- ACDF (Anterior Cervical Discectomy and Fusion) — removes the disc or bone spurs pressing on the cord from the front of the neck
- Cervical laminectomy — removes the back wall of the spinal canal to create more space for the cord
- Cervical laminoplasty — reshapes the back of the spine to expand the canal without full fusion
- Posterior cervical fusion — stabilizes the spine when multiple levels are involved or deformity is present
Treatment Pathway
1
Severity Grading and Monitoring
mJOA and Nurick scale scoring combined with MRI review for T2 intramedullary cord signal change. Mild stable myelopathy (mJOA 15–17) may be monitored with serial clinical assessments and imaging at 6–12 month intervals.
- mJOA and Nurick scale scoring
- MRI evaluation for T2 cord signal and T1 hypointensity (myelomalacia)
- Serial clinical monitoring for stable mild disease (mJOA 15–17)
2
Non-Surgical Management (Mild Stable Disease)
For mild myelopathy without progressive deficit, structured physical therapy targeting cervical stabilization, balance, and fine motor coordination. Cervical orthosis may reduce dynamic cord compression during high-risk activities. Escalate to surgical evaluation if mJOA score declines by ≥2 points, new T2 cord signal develops, or symptoms progress over 6 months.
- Cervical stabilization and proprioceptive physical therapy
- Cervical soft or rigid orthosis for activity modification
- Comorbidity optimization (smoking cessation, glycemic control in diabetes)
- Defined escalation triggers: mJOA decline ≥2 pts, new T2 signal, progressive deficit
3
Surgical Decompression
Moderate-to-severe myelopathy (mJOA <15) or progressive deficit warrants surgical decompression to halt progression and allow neurological recovery. Approach (anterior vs. posterior) is guided by compression location, number of levels, and cervical alignment.
- ACDF or cervical corpectomy — preferred for anterior compression at 1–2 levels with maintained lordosis
- Laminoplasty or laminectomy with fusion — preferred for multilevel disease (≥3 levels) or when posterior approach is favored
4
Post-Operative Rehabilitation
Occupational and physical therapy targeting hand coordination, fine motor control, balance, and gait. Most neurological improvement occurs within the first 12 months following decompression.
- Occupational therapy for hand function and ADL retraining
- Physical therapy for gait, balance, and strength
- Bladder management program if sphincter involvement is present
When to see a spine specialist
See a spine specialist or neurosurgeon promptly if you notice hand clumsiness, difficulty walking steadily, or unexplained leg weakness — these are warning signs of spinal cord compression that can worsen permanently if untreated. Seek emergency care if you develop sudden loss of bladder or bowel control.

Prognosis
The following factors are commonly associated with recovery outcomes for this condition based on published literature. Individual outcomes vary and depend on many clinical factors.
Prognosis Factors
Favorable
- Early surgical decompression before T2 intramedullary cord signal change (myelomalacia) develops
- Absence of T1 hypointensity within the cord, which indicates established myelomalacia and is associated with limited neurological recovery
- Higher preoperative mJOA score (mild-to-moderate disease) and shorter symptom duration before surgery
- Younger age at the time of decompression
Unfavorable
- T1 hypointensity within the cord on MRI, indicating myelomalacia — a marker of established cord injury with limited recovery potential
- Prolonged symptom duration before surgical decompression (commonly cited as >12–18 months)
- Multilevel disease with diffuse cord compression spanning several segments
- Severe preoperative disability (mJOA <12) with established neurological deficits

If I choose watchful waiting, how frequently should I be monitored, and which new symptoms should prompt an emergency evaluation?
Clinical Evidence
Frequently Asked Questions
What makes cervical myelopathy different from a pinched nerve?
A pinched nerve (radiculopathy) involves compression of a single nerve root, typically causing arm pain, numbness, or weakness on one side. Cervical myelopathy involves compression of the spinal cord itself, which can affect both arms and legs, balance, coordination, and bladder function. Myelopathy is generally a more serious condition requiring prompt evaluation.
Can cervical myelopathy get better on its own?
Unlike many spine conditions that can improve with rest and conservative care, cervical myelopathy rarely resolves without treatment. Most cases are stable for a period but then worsen in a stepwise fashion. Once the spinal cord sustains damage, some deficits may be permanent — which is why most spine specialists recommend surgery when myelopathy is confirmed rather than waiting.
Is surgery for cervical myelopathy effective?
Yes — surgical decompression typically stops or slows progression in the majority of patients. Many patients see improvement in hand coordination and walking stability, though recovery depends on how much cord damage occurred before surgery. Earlier surgery generally leads to better outcomes, which is why early diagnosis matters.
How is cervical myelopathy diagnosed?
Diagnosis begins with a clinical exam assessing reflexes, coordination, and grip strength. MRI is the primary imaging tool, showing the degree of spinal cord compression and any signal changes within the cord (a sign of existing damage). Nerve conduction studies may be used to rule out other conditions. Neurological grading scales such as the mJOA (modified Japanese Orthopaedic Association) score help quantify severity.
