What is Cervical Myelopathy?
Cervical myelopathy refers to spinal cord dysfunction due to compression in the cervical spine. This condition often results from degenerative changes such as cervical spondylosis, herniated discs, or other spinal abnormalities. Left untreated, cervical myelopathy can lead to severe and irreversible damage.
Symptoms of Cervical Myelopathy
The symptoms of cervical myelopathy can vary widely and often develop gradually. Common symptoms include:
- Neck Pain: Persistent neck pain or stiffness is a common early symptom.
- Weakness: Muscle weakness, particularly in the arms and hands.
- Numbness and Tingling: Often felt in the hands, fingers, and sometimes legs.
- Coordination Issues: Difficulty with fine motor skills, such as buttoning a shirt or writing.
- Balance Problems: Unsteady gait or frequent falls.
- Bladder and Bowel Dysfunction: In severe cases, loss of control over bladder and bowel functions.
If you experience any of these symptoms, it's essential to seek medical attention promptly for an accurate diagnosis and timely treatment.

Get A Second OpinionCauses of Cervical Myelopathy
The primary cause of cervical myelopathy is spinal cord compression, which can result from several factors:
Degenerative Disc Disease
As we age, the intervertebral discs in the spine can degenerate, leading to reduced disc height and the development of bone spurs. These changes can narrow the spinal canal and compress the spinal cord.
Herniated Discs
A herniated or slipped disc occurs when the soft inner material of the disc protrudes through the outer layer, putting pressure on the spinal cord.
Spinal Stenosis
Spinal stenosis is the narrowing of the spinal canal, which can compress the spinal cord and nerves. This condition is often a result of degenerative changes.
Trauma
Injuries to the cervical spine, such as fractures or dislocations, can lead to spinal cord compression and subsequent myelopathy.
Other Causes
Less common causes include tumors, infections, and inflammatory diseases that affect the spinal cord.
Risk Factors for Cervical Myelopathy
Certain factors can increase the likelihood of developing cervical myelopathy:
- Age: The risk increases with age, particularly after 50.
- Genetics: A family history of spinal disorders may predispose individuals to cervical myelopathy.
- Occupation: Jobs that involve repetitive neck movements or heavy lifting can contribute to spinal degeneration.
- Previous Neck Injuries: A history of neck injuries can increase the risk of developing myelopathy.
Diagnosing Cervical Myelopathy
Accurate diagnosis is essential for effective treatment. The diagnostic process typically involves:
Medical History and Physical Examination
A thorough medical history and physical examination can help identify symptoms and potential causes of cervical myelopathy.
Imaging Studies
Imaging studies such as X-rays, MRI (Magnetic Resonance Imaging), and CT (Computed Tomography) scans provide detailed images of the cervical spine, helping to identify areas of compression and degeneration.
Electromyography (EMG) and Nerve Conduction Studies
These tests evaluate the electrical activity of muscles and the speed of nerve signals, helping to assess the extent of nerve damage.
Treatment Options for Cervical Myelopathy
Treatment for cervical myelopathy aims to relieve symptoms, prevent further damage, and improve the patient's quality of life. The treatment approach can vary depending on the severity of the condition.
Non-Surgical Treatments
Medications
Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids can help reduce inflammation and alleviate pain.
Physical Therapy
Physical therapy can improve strength, flexibility, and coordination. Specific cervical myelopathy exercises may include neck stretches, strengthening exercises, and balance training.
Immobilization
In some cases, a cervical collar may be recommended to immobilize the neck and reduce pressure on the spinal cord.
Surgical Treatments
When non-surgical treatments are insufficient, surgery may be necessary to relieve spinal cord compression and prevent further neurological deterioration. Common surgical options include:
Anterior Cervical Discectomy and Fusion (ACDF)
This procedure involves removing the damaged disc and fusing the adjacent vertebrae to stabilize the spine.
Posterior Cervical Laminectomy
In this procedure, the surgeon removes the lamina (the back part of the vertebra) to create more space for the spinal cord.

This surgery involves removing a portion of the vertebra and discs to decompress the spinal cord, followed by spinal fusion to maintain stability.
Prognosis and Long-Term Outlook
The prognosis for cervical myelopathy varies depending on the severity of the condition and the timeliness of treatment. Early diagnosis and appropriate treatment can significantly improve outcomes and prevent permanent neurological damage.
Rehabilitation
Post-surgical rehabilitation is crucial for recovery. Physical therapy, occupational therapy, and other rehabilitation programs can help patients regain strength, mobility, and function.
Lifestyle Modifications
Making lifestyle changes, such as maintaining a healthy weight, practicing good posture, and avoiding activities that strain the neck, can help prevent further spinal degeneration and reduce the risk of recurrence.
Frequently Asked Questions
1. What are the symptoms of cervical myelopathy?
Symptoms include neck pain, difficulty with balance, muscle weakness, numbness, and loss of fine motor skills in the hands.
2. What causes cervical myelopathy?
It is caused by compression of the spinal cord in the cervical (neck) region, often due to degenerative changes like herniated discs or arthritis.
3. How is cervical myelopathy treated?
Treatment includes physical therapy, medications for pain relief, and in severe cases, surgery to decompress the spinal cord and prevent further damage.
4. How is cervical myelopathy diagnosed?
Diagnosis involves MRI or CT scans to assess spinal cord compression, along with neurological exams to evaluate motor and sensory function.
5. What exercises help cervical myelopathy?
Gentle neck stretches and strengthening exercises, often guided by a physical therapist, can help improve mobility and reduce symptoms.
