What is Cervical Myelopathy?
Cervical myelopathy occurs when the spinal canal narrows (stenosis) to the point that it begins to bruise or compress the spinal cord. Unlike a pinched nerve (radiculopathy) which causes pain in one specific area, myelopathy affects the entire spinal cord's ability to relay signals between the brain and the rest of the body.
Damage to the spinal cord is often irreversible. The primary goal of intervention is usually to stop the progression rather than to reverse existing deficits, though many patients do see improvement after surgery.
Key Symptoms & Warning Signs
Myelopathy often presents "insidiously," meaning symptoms develop slowly and may be mistaken for normal aging. Watch for these neurological red flags:
Difficulty buttoning shirts, handwriting, or handling coins. Often described as "clumsy hands."
A wide-based, unsteady walk. Feeling like you are "walking on cotton" or might trip easily.
Numbness or pins-and-needles sensations in the hands and feet.
Overactive reflexes (hyperreflexia) or the presence of signs like Hoffmann's or Babinski's sign.
Causes & Risk Factors
The most common cause. Age-related wear causes discs to bulge and bone spurs to grow, narrowing the space available for the spinal cord.
A condition where the ligaments supporting the spine turn into bone, significantly narrowing the spinal canal.
Some individuals are born with a narrower spinal canal, making them more susceptible to cord compression earlier in life.
Diagnosis & Imaging
Early diagnosis is vital to prevent permanent disability. Specialists use a combination of physical exams and advanced imaging:
- 1
MRI (Gold Standard): Used to see the spinal cord itself. A "white spot" (signal change) inside the cord on an MRI often indicates bruising or swelling.
- 2
CT Myelography: For patients with pacemakers or metal that prevents an MRI, a dye is injected into the spinal fluid to highlight compression on a CT scan.
- 3
Clinical Provocation: Tests like the Hoffmann's sign (flicking the fingernail) can confirm hyperreflexia associated with myelopathy.
Treatment & Surgery
While very mild cases may be observed closely, the standard treatment for moderate-to-severe myelopathy is surgical decompression.
The goal is to provide more room for the spinal cord. This can be done from the front (Anterior Cervical Discectomy and Fusion - ACDF) or from the back (Laminectomy or Laminoplasty).
Non-Surgical Management (Limited)
- Observation for very stable, mild symptoms.
- Physical therapy to improve balance and strength.
- Medication for symptom relief (nerve pain meds).
Surgery is primarily a safety procedure to prevent you from getting worse. While many patients regain function, the primary success of surgery is "stabilization."
Prognosis & Stages
Cervical myelopathy usually follows a "step-wise" progression. A patient may stay stable for months or years, followed by a sudden decline in function, then another period of stability.
Minor hand clumsiness; able to walk without assistance.
Significant difficulty with fine motor skills; unsteady gait but still mobile.
Requires assistance or walking aids; significant loss of hand function.
Frequently Asked Questions
Is neck pain always a symptom?
No. Surprisingly, some of the most severe cases of myelopathy involve very little neck pain. The focus is on the limb function and balance.
Can physical therapy cure myelopathy?
Physical therapy cannot remove the physical bone or disc pressing on the cord. It can help with balance, but it does not address the underlying compression.
