What to Know About Cervical Myelopathy
Cervical myelopathy is a serious condition that affects the spinal cord in the neck (cervical spine), causing symptoms that can significantly impact a person’s quality of life. As the spinal cord becomes compressed, it can lead to nerve damage that affects not just the neck but other parts of the body as well. This condition is often caused by degenerative changes in the spine but can also result from trauma or injury.
In this article, we will explore what cervical myelopathy is, its causes, symptoms, diagnosis, and the treatment options available for those affected by the condition.
What is Cervical Myelopathy?
Cervical myelopathy is a condition that occurs when the spinal cord in the neck is compressed or damaged. This compression can lead to a variety of neurological symptoms, including pain, weakness, and difficulty with coordination and balance. Unlike cervical radiculopathy, which affects the nerve roots and usually causes pain localized to specific areas, cervical myelopathy impacts the spinal cord, leading to more widespread and systemic issues.
The spinal cord is a crucial part of the nervous system that transmits signals between the brain and the rest of the body. When the spinal cord is compressed, it can lead to serious, progressive symptoms that worsen over time if left untreated.
Causes of Cervical Myelopathy
There are several common causes of cervical myelopathy:
- Degenerative disc disease: As people age, the discs in the spine can naturally degenerate. This wear and tear can cause the discs to collapse, narrowing the space in the spinal canal and putting pressure on the spinal cord.
- Herniated discs: A herniated or bulging disc occurs when the soft, jelly-like center of a spinal disc pushes out through its tougher exterior. When this happens in the cervical spine, the disc can press on the spinal cord.
- Spinal stenosis: This is the narrowing of the spinal canal, often caused by bone spurs or thickened ligaments. Spinal stenosis can lead to compression of the spinal cord, causing myelopathy.
- Trauma or injury: Car accidents, falls, or sports injuries can cause damage to the cervical spine, leading to cervical myelopathy.
- Tumors: In rare cases, tumors can grow inside or around the spinal canal, compressing the spinal cord and leading to myelopathy.
Symptoms of Cervical Myelopathy
The symptoms of cervical myelopathy can vary widely depending on the severity and progression of the condition. Early symptoms might be mild, but they often worsen over time. Common symptoms include:
- Neck pain: Pain in the neck is often one of the first symptoms of cervical myelopathy, though not everyone with the condition experiences pain.
- Numbness or tingling: Many people with cervical myelopathy experience numbness, tingling, or a pins-and-needles sensation in the arms, hands, or legs.
- Difficulty walking or maintaining balance: As the condition progresses, it can affect the nerves responsible for balance and coordination, leading to difficulty walking or frequent falls.
- Weakness in the arms, hands, or legs: Loss of strength in the hands or arms is a common symptom, as is leg weakness that can make it difficult to move or stand for long periods.
- Loss of fine motor skills: Activities that require precise hand movements, such as buttoning a shirt or writing, may become difficult.
- Bladder or bowel dysfunction: In severe cases, cervical myelopathy can interfere with the nerves that control bladder and bowel function.
Because cervical myelopathy affects the spinal cord, the symptoms often worsen over time. Early diagnosis and treatment are crucial to prevent permanent damage.
Diagnosing Cervical Myelopathy
Diagnosing cervical myelopathy typically involves a combination of physical exams, imaging tests, and neurological assessments.
- Physical examination: A doctor will assess your symptoms, including checking your reflexes, muscle strength, and range of motion. They may also test your ability to walk and maintain balance.
- Imaging tests:
- MRI scans: An MRI is often the most effective way to diagnose cervical myelopathy, as it provides detailed images of the soft tissues in the spine, including the spinal cord and discs.
- CT scans: A CT scan can help detect bone spurs, fractures, or other structural abnormalities that may be compressing the spinal cord.
- X-rays: X-rays can show changes in the alignment or structure of the cervical spine, such as narrowed spaces between the vertebrae or bone spurs.
- Nerve conduction studies: Tests like electromyography (EMG) can measure the electrical activity in your muscles and help determine the extent of nerve damage.
Treatment Options for Cervical Myelopathy
The treatment for cervical myelopathy depends on the severity of the condition. In some cases, non-surgical treatments can relieve symptoms, while others may require surgery.
Non-Surgical Treatments
For mild to moderate cases of cervical myelopathy, non-surgical treatments may be effective in managing symptoms:
- Medications: Anti-inflammatory medications, such as NSAIDs, can help reduce pain and inflammation. In some cases, corticosteroids may be prescribed to reduce swelling around the spinal cord.
- Physical therapy: A physical therapist can guide you through exercises designed to strengthen the muscles around the spine, improve posture, and enhance flexibility. Physical therapy can help alleviate pressure on the spinal cord and improve mobility.
- Lifestyle modifications: Correcting your posture, avoiding activities that strain the neck, and making ergonomic adjustments in your work or home environment can help prevent the condition from worsening.
Surgical Treatments
In more severe cases, or when non-surgical treatments are ineffective, surgery may be required to relieve the pressure on the spinal cord:
- Decompression surgery: This procedure involves removing parts of the vertebrae, ligaments, or discs that are compressing the spinal cord. Decompression surgery helps create more space in the spinal canal.
- Discectomy: If a herniated disc is causing the compression, a discectomy may be performed to remove part or all of the disc.
- Spinal fusion: In cases where the spine is unstable due to degeneration or trauma, spinal fusion surgery may be recommended to stabilize the spine by fusing two or more vertebrae together.
Recovery After Cervical Myelopathy Surgery
Recovery from cervical myelopathy surgery can take several weeks to months, depending on the individual and the type of surgery performed. After surgery, patients will typically undergo physical therapy to regain strength and mobility. It’s important to follow your doctor’s post-surgery guidelines to avoid complications and ensure a smooth recovery.
During the recovery process, patients may experience some discomfort, but this usually improves over time. Physical therapy is essential for improving flexibility and restoring function after surgery.
Cervical Myelopathy vs. Other Conditions
It’s important to distinguish cervical myelopathy from other conditions that affect the spine:
- Cervical myelopathy vs radiculopathy: While both conditions involve the cervical spine, myelopathy affects the spinal cord, leading to widespread symptoms, whereas radiculopathy affects the nerve roots, causing localized pain in specific areas like the arms or shoulders.
- Cervical myelopathy vs stenosis: Spinal stenosis refers to the narrowing of the spinal canal, which can cause myelopathy if it compresses the spinal cord.
Long-Term Prognosis and Disability
The long-term prognosis for cervical myelopathy depends on early diagnosis and appropriate treatment. If the condition is left untreated, it can lead to permanent nerve damage and disability. Severe cases can result in long-term issues with mobility, coordination, and strength.
In some cases, cervical myelopathy may qualify as a disability, particularly if it significantly impairs a person’s ability to work or perform daily activities. Early treatment, including surgery if necessary, can improve the long-term outlook and help patients maintain a good quality of life.
