What Is Cervical Myelopathy?
Imagine dropping keys constantly because your hands won't cooperate. Or tripping over nothing while walking. That might be Cervical Myelopathy, not just aging. It's spinal cord damage caused by narrowing in your neck spine, called cervical spinal stenosis. Around 9 in 100 people over 70 live with this condition, yet many dismiss symptoms as normal aging. Unlike simple neck pain, this involves actual nerve injury.
Your cervical spine has 7 vertebrae with discs between them. Over decades, discs lose water and flatten, bone spurs form, and ligaments thicken. When the spinal canal shrinks below 13mm (normal is 17-18mm), pressure builds on the spinal cord. This compression disrupts signals traveling between brain and body.
Early Warning Signs
Early symptoms often hide behind everyday annoyances. You might notice:
- Dropping utensils or struggling with buttons
- Tingling toes even when feet aren't cramped
- Neck stiffness worse after looking down at phones
- Burning sensations shooting into arms
About 72% of patients report hand clumsiness before gait issues appear. One man told his doctor he needed "bigger coffee mugs"-his grip had weakened enough to spill liquid easily. These changes happen gradually; 45% of cases progress steadily over years.
When Urgent Symptoms Appear
Some signs demand quick action. Watch for:
- Sudden leg weakness causing frequent falls
- Bowel/bladder urgency problems
- Burn-like tingling spreading down limbs
Urinary incontinence affects 35% of severe cases. Without intervention, paralysis risks rise sharply-up to 60% deteriorate neurologically within 5 years untreated.
How Doctors Diagnose
Two things confirm the diagnosis: physical tests and imaging. Your doctor checks reflexes and strength, scoring you on the Japanese Orthopaedic Association scale. Scores under 14 signal serious myelopathy.
MRI shows exactly what's pinching nerves: disc bulges pressing inward, thickened ligaments, or bony encroachment. Over half the population over 40 has narrow spinal canals, but only those showing *cord signal changes* truly have myelopathy. CT scans help too when metal implants block MRI views.
Treatment Paths Explained
If symptoms barely interfere with life, doctors may suggest: rest, anti-inflammatory meds, or physical therapy. But evidence shows only 28% improve long-term without surgery.
Deciding On Surgery
For moderate/severe cases, surgery becomes essential. Surgeons pick approaches based on:
- Number of affected segments
- Your spinal alignment angle
- Presence of bone spurs
Anterior procedures remove discs through small front-of-neck cuts. Posterior approaches work from the backside. Each has trade-offs summarized below:
