What is the Cervical Spine?
The phrase ‘cervical spine’ refers to a well-engineered construction of bones, nerves, muscles, ligaments, and tendons found in the neck. It is comprised of seven specific bones (vertebrae) as well as intervertebral discs that separate them.
The structure protects the spinal cord and nerves and their vital function to send messages of movement and sensation from the brain to all points in the body. This portion of the spine also supports the head and facilitates blood flow. Though strong and flexible in many ways, the cervical spine is also delicate and susceptible to damage.
What Is Cervical Radiculopathy?
Like all bones and joints in the body, the cervical spine is susceptible to degenerative changes and arthritis. If the degenerative changes cause narrowing of the small tunnels where the nerves leave the spine, the nerves can become compressed and stop functioning properly. This is called cervical radiculopathy.
What are the Symptoms of Cervical Radiculopathy?
Cervical radiculopathy can cause partial or complete loss of sensory and/or motor function. Depending on the particular nerve that is affected, symptoms include:
- Neck pain
- Arm pain
- Numbness in hands or in the arm
- Weakness of movement in the arm
- Loss of dexterity
What Causes Cervical Radiculopathy?
Cervical radiculopathy can be a result of neck injury, or it can be caused by slow arthritic changes in the cervical vertebrae. A slipped disc in the cervical spine can also cause cervical radiculopathy. In a paper on cervical injury, authors identified these common reasons for spine injury:
- Trauma-Related
- Motor vehicle accidents
- Falls
- Blunt trauma
- Sports-related injuries
- Spinal stenosis
- Non-Trauma Related
- Compression fractures from arthritis, osteoporosis, or cancer
- A congenitally narrow spinal canal
- Various bone conditions (ankylosing spondylitis, for example)
Neck injuries are more common in men than women. The majority of injuries occur between the ages of 15 and 30, and after the age of 65.
When Should I Consult a Doctor?
Your doctor is your first line of defence against long-term problems due to cervical radiculopathy. Consult a neurosurgeon if you are experiencing:
- Neck pain
- Arm pain in a some area
- You can’t touch your chin to your chest due to neck stiffness
- You have progressive numbness or weakness of a movement in your arm
- Pain you experience is persistent
If you experience sudden onset of weakness, please seek medical attention at an emergency room.
How is Cervical Radiculopathy Diagnosed?
The diagnosis of cervical radiculopathy is made by a neurosurgeon. The diagnosis is based upon symptoms, medical history, and a physical examination and as-needed tests such as:
- MRI – provides an enhanced view of body structures, including the spinal cord
- CT Scan – provides information about bone abnormalities
- X-rays – to analyse spinal alignment, disc degeneration, arthritis
- Nerve Conduction Studies – to assess nerve damage
An accurate and comprehensive view of the injury is provided by these easy-to-tolerate diagnostics. The results form the basis for determining which treatments will provide optimal healing.
How is Cervical Radiculopathy Treated?
Neck pain unrelated to trauma (i.e., disc herniation) may resolve symptoms with medication, rest, and physical therapy. In some instances, an injection of corticosteroids may be used to temporary temporarily relieve pain. If the spinal cord is also compressed and there are symptoms, surgery is usually indicated.
What is Cervical Spine Surgery?
Several different surgical procedures are utilised in the treatment of a nerve compression. Despite their differences, they all:
- Decompress the spinal cord and/or nerves
- Stabilise or improve spinal stability
- Stabilise or correct spinal alignment
In addition to determining the appropriate surgical procedure, your neurosurgeon will also determine whether spinal fusion is also indicated. In spinal fusion, two or more vertebrae are connected via various devices such as screws, cages and/or plates. This works to provide stability in the cervical spine and strengthen it to alleviate further pain.
Some of the surgeries commonly recommended addressing cervical radiculopathy are:
- Cervical Laminoforaminotomy – a section of the bony roof of the spine (the lamina) is accessed through an incision at the back of the neck and is then partially removed to create more space for the nerves.
- Anterior Cervical Discectomy and Fusion – the cervical spine is accessed through a small incision on the front of the neck, allowing removal of the disc and/or bone spurs that are causing nerve compression.
What Can I Expect After Surgery for Cervical Radiculopathy?
When your surgery is complete, you will be taken to an observation room so that you may be monitored. When appropriate, you will be taken to your hospital room to continue your recovery. Most patients stay in hospital for one or two nights. When appropriate, you will be released with instructions for home care and follow-up.
Do I Follow-Up with Dr Sammons?
Yes. Dr Sammons will follow up with you while you are in hospital. At that time, Dr Sammons will examine you and talk about your pain levels, make a determination on when you should return to work, whether you need rehab, and answer your questions. She may recommend x-rays or a CT scan to assess spinal alignment and monitor spine function. After you are released, you will be contacted by a practice nurse to set up your next visit.
What is the Prognosis after Cervical Spine Surgery?
The prognosis following spinal surgery is very good. Some procedures have been shown to provide relief in more than 80% of patients. The vast majority of patients make a good recovery and are functionally better than before surgery.
