Cervical radiculopathy and cervical myelopathy are two terms that you may encounter if you’re experiencing neck pain, weakness, or numbness. They may sound similar, but they’re distinctly different conditions that affect your spinal cord and nerves in different ways. It’s important to understand the difference between the two as they require different treatments.
Cervical radiculopathy occurs when a nerve root in your neck gets compressed or inflamed. This can happen due to a herniated disc, bony spurs, or degenerative changes in the spine. When a nerve is affected, it can cause pain, weakness, numbness, or tingling in the shoulder, arm, or hand on the same side. On the other hand, cervical myelopathy is a condition where the spinal cord in your neck gets compressed due to changes in the vertebrae or discs. It can lead to a range of symptoms, including weakness or clumsiness in the hands, arms, or legs, difficulty with coordination, difficulty walking, and loss of bowel or bladder control.
If you’re experiencing any symptoms of neck pain, weakness, or numbness, it’s worth seeking medical attention to determine whether you have cervical radiculopathy or cervical myelopathy. While the symptoms may be similar, the underlying causes and treatments can be different, and a correct diagnosis is essential to guide appropriate treatment options. With the proper care, most patients can expect to recover, reduce their pain, and regain their daily activities without any further complications.
Cervical Spine
The cervical spine, also known as the neck, is composed of seven vertebrae (C1 to C7) that support the weight of the head and enable a wide range of motion. The cervical spine has a curvature that helps absorb shock, and it also protects the spinal cord, which begins at the brainstem and passes through the center of each vertebra. The cervical spine plays a crucial role in the stability and movement of the head and the upper extremities.
Spinal nerves
Spinal nerves are an important part of the nervous system, specifically involved in the transmission of sensory information, as well as motor signals to different parts of the body. The spinal cord is connected to these nerves, which exit the spinal cord through openings called intervertebral foramina.
Cervical radiculopathy and cervical myelopathy are both conditions that can affect the spinal nerves in the cervical (neck) region. However, there are some key differences between these two conditions.
Differences between cervical radiculopathy and cervical myelopathy
- Cervical radiculopathy: This condition occurs when one or more spinal nerve roots in the cervical region become compressed or inflamed. This can result in pain, weakness, numbness, or tingling sensations in the areas of the body innervated by those nerves. In some cases, cervical radiculopathy may also cause reflex abnormalities or muscle atrophy.
- Cervical myelopathy: This condition occurs when the spinal cord is compressed or damaged in the cervical region. This can result in a range of symptoms, including muscle weakness, stiffness, unsteadiness, or loss of coordination. In some cases, cervical myelopathy may also cause bowel or bladder dysfunction, or even paralysis.
Diagnosis and treatment
Both cervical radiculopathy and cervical myelopathy can be diagnosed through a physical examination, as well as imaging tests such as MRIs or CT scans. Treatment options may include rest, physical therapy, medication, or, in severe cases, surgery. However, the specific treatment plan will depend on the underlying cause and severity of the condition, as well as the individual’s overall health and medical history.
Conclusion
Spinal nerves play an important role in the functioning of the nervous system, and conditions such as cervical radiculopathy and cervical myelopathy can have a significant impact on their performance. Understanding the differences between these two conditions can help individuals and healthcare providers make informed decisions about diagnosis and treatment, and improve the overall outcome of treatment.
| Condition | Symptoms | Treatment |
|---|---|---|
| Cervical radiculopathy | Pain, weakness, numbness, tingling, reflex abnormalities, muscle atrophy | Rest, physical therapy, medication, surgery (in severe cases) |

Symptoms of Cervical Radiculopathy
Cervical radiculopathy is a nerve disorder caused by a compressed nerve root in the cervical spine. The nerve roots originating from the cervical spine provide sensation and motor control to the head, neck, arms, and shoulders. When these nerves become compressed, they can cause symptoms ranging from mild discomfort to severe pain and weakness. Below are some common symptoms of cervical radiculopathy:
- Neck pain
- Arm pain
- Tingling or numbness in the arms or fingers
- Muscle weakness in the arms or shoulders
- Loss of grip strength
- Muscle spasms
- Difficulty with fine motor skills, such as buttoning a shirt or holding a pen
Causes of Cervical Myelopathy
Cervical myelopathy is a condition that involves compression of the spinal cord in the neck region. This can be caused by a variety of factors, which may be related to trauma, degeneration of the spine, or even hereditary conditions. Here are some of the primary causes of cervical myelopathy:
- Spinal Stenosis: This is a condition where the spinal canal is narrow, resulting in pressure on the spinal cord. This narrowing can be caused by bone spurs, herniated discs, or thickened ligaments.
- Herniated Discs: Disc herniation occurs when the outer layer of the disc weakens and the inner layer leaks out, putting pressure on the spinal cord and nerves. This can occur due to degenerative changes, trauma, or repetitive stress over time.
- Spinal Tumors: Tumors that develop on the spinal cord or surrounding tissues can cause compression that leads to myelopathy. These tumors may be benign or malignant.
Other potential causes of cervical myelopathy include spinal cord inflammation due to infection, autoimmune conditions, or dislocation or fracture of the vertebrae in the neck. Some individuals may be genetically predisposed to developing cervical myelopathy due to abnormalities with the structure of their spinal cord or other tissues.
It is important to note that cervical myelopathy can develop slowly over time, as in the case of degenerative changes in the spine or gradual compression of the spinal cord. However, in some cases, it may occur suddenly due to trauma or acute changes in the spine.
| Cause | Description |
|---|---|
| Spinal Stenosis | Narrowing of the spinal canal due to bone spurs, herniated discs, or thickened ligaments |
| Herniated Discs | Leakage of the inner layer of the disc due to degenerative changes, trauma, or repetitive stress |
| Spinal Tumors | Benign or malignant tumors that develop on the spinal cord or surrounding tissues |
If you are experiencing symptoms of cervical myelopathy, it is important to seek medical attention promptly to determine the underlying cause and develop an appropriate treatment plan. While some cases may resolve with conservative measures such as physical therapy or medications, others may require surgery to relieve pressure on the spinal cord and prevent further damage.
Treatment options for cervical spine conditions
When it comes to treating cervical spinal conditions, there are various options available depending on the specific condition. In this section, we will discuss the treatment options for cervical radiculopathy and cervical myelopathy.
Cervical Radiculopathy Treatment Options:
- Physical Therapy: A rehabilitation program that includes exercises and stretches to improve neck mobility and strengthen muscles. This can also include massage or hot/cold therapy.
- Medications: Over-the-counter or prescription medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants to relieve pain and inflammation.
- Injections: Steroid injections directly into the affected nerve root to decrease inflammation and relieve pain.
- Surgery: If conservative treatments fail, surgery may be necessary to remove the herniated disc or bone spur that is compressing the nerve root.
Cervical Myelopathy Treatment Options:
When it comes to cervical myelopathy, there are fewer options available. Treatment depends on the severity of the condition and the underlying cause.
Conservative treatments may be used to manage symptoms, but surgery is often necessary to prevent further damage to the spinal cord.
Surgery options may include:
- Decompression Surgery: Removing the source of compression on the spinal cord, such as herniated disks or bone spurs.
- Fusion Surgery: Joining two or more vertebrae together to stabilize the spine.
- Artificial Disk Replacement: Removing the damaged disk and replacing it with an artificial one to maintain spinal motion.
It’s important to consult a medical professional to determine the appropriate treatment plan for your cervical spine condition. While conservative treatments may alleviate symptoms, surgery may be necessary to prevent further damage and improve quality of life.
Imaging techniques for cervical spine disorders
When it comes to diagnosing cervical spine disorders such as cervical radiculopathy and cervical myelopathy, imaging techniques play a crucial role in identifying the underlying cause of the symptoms. Here are some of the commonly used imaging techniques:
- X-rays: This imaging technique uses radiation to produce images of the bones and helps in detecting any abnormalities in the structure of the cervical spine. X-rays are often the first test performed for cervical spine disorders.
- Magnetic Resonance Imaging (MRI): This noninvasive imaging technique uses a magnetic field and radio waves to produce detailed images of the cervical spine, including the soft tissues and nerves. MRI is the preferred imaging technique for diagnosing cervical myelopathy, as it can detect spinal cord compression and damage.
- Computed Tomography (CT) Scan: This imaging technique involves the use of X-rays and computer technology to produce detailed images of the bones and soft tissues in the cervical spine. CT scan is often used in combination with myelography to detect any abnormalities in the spinal cord and nerve roots.
While these imaging techniques can provide valuable information about the cervical spine, they are not always conclusive and may need to be used in combination with other diagnostic tests such as electromyography (EMG) and nerve conduction studies (NCS).
If you have been experiencing symptoms of cervical spine disorders, it is important to consult with a healthcare professional who can perform a thorough physical examination and recommend appropriate diagnostic tests to determine the underlying cause of your symptoms.
