Cervical Myelopathy
Spinal cord compression in the neck that affects coordination, balance, and limb function
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.
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
Treatment Options
Conservative (Non-Surgical)
- 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 Options
- 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
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.
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.
