What Is Cervical Myelopathy?
Cervical myelopathy occurs when the spinal cord becomes compressed in the neck (cervical spine).
Unlike a pinched nerve, which affects a single nerve root, cervical myelopathy affects the spinal cord itself. Because the spinal cord carries signals to the entire body, compression can cause problems with balance, hand function, walking, and coordination.
Cervical myelopathy is one of the most common reasons for spinal cord dysfunction in adults over the age of 50.
Why Is Cervical Myelopathy Important?
The spinal cord is a delicate structure that controls movement, sensation, balance, and coordination.
When the spinal cord is compressed for a prolonged period, symptoms may gradually worsen and can become permanent if left untreated.
Early diagnosis is important because treatment is often aimed at preventing further neurological deterioration.
Common Symptoms
Symptoms usually develop gradually over months or years, although some patients notice a more rapid decline.
Common symptoms include:
Problems with Walking and Balance
- Feeling unsteady while walking
- Frequent tripping or stumbling
- Difficulty walking in crowded areas or on uneven ground
- Loss of balance
Problems with Hand Function
- Difficulty buttoning shirts
- Trouble writing
- Reduced hand dexterity
- Frequently dropping objects
- Clumsiness of the hands
Numbness and Tingling
- Tingling in the hands or fingers
- Numbness in the arms or hands
- Altered sensation in the legs
Weakness
- Weakness in the hands
- Weakness in the arms or legs
- Difficulty climbing stairs
Neck Symptoms
- Neck pain or stiffness
- Reduced neck movement
Not every patient experiences all of these symptoms.
What Causes Cervical Myelopathy?
The most common cause is age-related wear and tear of the cervical spine.
Over time, several changes may occur:
Disc Degeneration
The discs lose water content and height, reducing the space available for the spinal cord.
Bone Spurs
Arthritic changes may lead to extra bone formation that narrows the spinal canal.
Thickening of Ligaments
The ligaments supporting the spine may thicken and contribute to spinal canal narrowing.
Disc Herniation
A bulging or herniated disc can directly compress the spinal cord.
Congenitally Narrow Canal
Some people are born with a spinal canal that is naturally smaller than average, making them more susceptible to cord compression later in life.
How Is It Diagnosed?
Diagnosis begins with a detailed medical history and physical examination.
Your doctor will assess:
- Walking pattern and balance
- Hand coordination and dexterity
- Muscle strength
- Sensation
- Reflexes
- Signs of spinal cord dysfunction
Certain abnormal reflexes may suggest spinal cord compression.
What Tests Are Required?
MRI Scan
MRI is the most important test for diagnosing cervical myelopathy.
It shows:
- Spinal cord compression
- Disc herniations
- Bone spurs
- Narrowing of the spinal canal
- Changes within the spinal cord itself
X-rays
X-rays evaluate spinal alignment and degenerative changes.
CT Scan
A CT scan may provide additional information about bony narrowing.
Nerve Tests (EMG/NCS)
These tests may occasionally be used when symptoms could be related to other nerve conditions.
Can Cervical Myelopathy Improve Without Surgery?
Unlike many cases of cervical radiculopathy, cervical myelopathy is usually a progressive condition.
Once the spinal cord is compressed, symptoms often remain stable or gradually worsen over time.
Non-surgical treatment may help relieve neck pain but generally does not reverse spinal cord compression.
Because of this, surgery is frequently recommended when significant spinal cord compression is present.
When Is Surgery Recommended?
Surgery is commonly advised when:
- Symptoms are affecting walking or balance
- Hand function is deteriorating
- Weakness is present
- MRI shows significant spinal cord compression
- Symptoms are progressively worsening
The primary goal of surgery is to prevent further spinal cord damage and neurological decline.
Some patients also experience meaningful improvement in symptoms after surgery.
Surgical Treatment Options
The choice of surgery depends on the location of compression, spinal alignment, the number of affected levels, and individual patient factors.
Anterior Cervical Discectomy and Fusion (ACDF)
The damaged disc is removed through a small incision in the front of the neck, relieving pressure on the spinal cord and nerves.
Cervical Corpectomy
In some cases, part of a vertebral body must be removed to adequately decompress the spinal cord.
Posterior Cervical Laminectomy
The back part of the vertebra is removed to create more space for the spinal cord.
Laminectomy with Fusion
When additional stability is required, decompression may be combined with spinal fusion.
Laminoplasty
In selected patients, the spinal canal can be expanded while preserving motion.
Your surgeon will recommend the procedure best suited to your specific condition.
What Is the Recovery Like?
Recovery varies from patient to patient.
Many patients notice:
- Improvement in balance
- Better hand function
- Increased confidence while walking
- Reduced numbness
However, recovery depends on:
- Severity of spinal cord compression
- Duration of symptoms before surgery
- Age
- Overall health
In long-standing cases, surgery may prevent further deterioration rather than completely reverse all symptoms.
What Happens If Cervical Myelopathy Is Left Untreated?
Without treatment, some patients may experience:
- Progressive difficulty walking
- Increasing balance problems
- Worsening hand function
- Weakness in the arms or legs
- Loss of independence in daily activities
Severe untreated cases can result in significant neurological disability.
Frequently Asked Questions
Is cervical myelopathy the same as a pinched nerve?
No.
A pinched nerve (radiculopathy) affects a single nerve root. Cervical myelopathy involves compression of the spinal cord itself.
Can physiotherapy cure cervical myelopathy?
Physiotherapy may help maintain mobility and strength, but it cannot remove spinal cord compression.
Is surgery always necessary?
Not always. Mild cases may be monitored closely. However, surgery is commonly recommended when there is evidence of spinal cord dysfunction or progressive symptoms.
Will surgery restore normal function?
Many patients improve after surgery, but the degree of recovery varies. Earlier treatment generally offers the best chance of neurological improvement.
Is cervical myelopathy an emergency?
Most cases develop gradually. However, rapidly worsening weakness, severe difficulty walking, or sudden neurological decline requires urgent medical evaluation.
When Should You Seek Medical Attention?
Consult a spine specialist if you experience:
- Increasing difficulty with balance or walking
- Hand clumsiness
- Progressive weakness
- Frequent falls
- Loss of coordination
- Persistent numbness in the hands
Early diagnosis and treatment can help prevent permanent spinal cord injury.
