Cervical Radiculopathy

Cervical Radiculopathy

What Is Cervical Radiculopathy?

Often referred to as a "pinched nerve," Cervical radiculopathy is an injury to a nerve in the neck that has branched off from the spinal cord. This can cause discomfort that radiates into the shoulder and/or arm, as well as muscular weakness and numbness. Cervical radiculopathy is frequently caused by "wear and tear" changes in the spine that occur with age, such as arthritis. It is most often induced by a traumatic incident leading to a herniated disk in young people. In some situations, no external trauma is connected with the start of symptoms. In most cases, conservative therapy, which includes medication and physical treatment, effectively treats cervical radiculopathy.

What Causes Pinched Nerves?

Most people with cervical radiculopathy or pinched nerves have degenerative changes in the spine that occur as we age or from a herniated, or bulging, intervertebral disk injury.

Degenerative changes 

The disks in the spine begin to bulge as they age. They also lose water content and become drier. This problem causes the loss of disk space height and the development of disk space collapse. As the disks drop in height, the vertebrae come closer together. The body responds to a collapsed disk by creating more bone—known as bone spurs—around the disk to strengthen it. These bone spurs help to support the spine. Unfortunately, they can also compress the nerve roots, narrow the foramen—the small holes on each side of the spinal column where nerve roots emerge—and pinch the nerve root.

Discs that are degenerating develop arthritis (spondylitis) or spondylosis. These changes are typical and occur in everyone. Almost half of all people between the ages of forty-five and eighty have worn disks and pinched nerves that do not produce unpleasant symptoms. It is unknown why some patients experience symptoms while others do not.

Herniated disks 

When the jelly-like center (nucleus) of a disk pushes against its outer ring (annulus), it herniates. The nucleus may squeeze all the way through if the disk is severely worn or injured. When the herniated disk swells outward toward the spinal canal, it puts pressure on the sensitive nerve root, resulting in pain and weakness in the area. A herniated disk is most frequently caused by lifting, tugging, bending, or twisting.

Signs and Symptoms of a Pinched Nerve

The pain caused by a pinched nerve usually begins at the neck and travels down the arm over the area served by the injured nerve. This discomfort is typically described as burning or sharp. Turning one's head may increase the level of suffering. Other signs include:

  • Tingling in the fingers or hand (commonly referred to as "pins and needles")
  • Weakness in the muscles of the arm, shoulder, or hand
  • Loss of sensation

Some people claim that pain abates when they put their hands on top of their heads. This action may provide temporary relief for pressure on the nerve root.

Diagnosing Cervical Radiculopathy

Your doctor will begin by asking you about your medical history and general health. They will then assess your neck, shoulder, arms, and hands for muscular weakness, loss of sensation, or any changes in your reflexes. To test if your problem is caused by posture, your doctor may request that you perform specific neck and arm exercises to see if they help.

Imaging and Tests

  • An X-ray is a form of radiation that passes through the body, producing pictures of structural features such as bones. An x-ray will show whether your bones are aligned properly in your neck. It can also determine if there is any narrowing of the foramen and damage to the disks and other details.
  • A CT scan is more detailed than a regular x-ray and may be used to determine whether you have developed bone spurs near the foramen in your cervical spine.
  • MRIs produce higher-quality images of the body's soft tissues. An MRI scan of the neck can reveal if nerve compression is caused by injury to soft tissues, such as a bulging or herniated disk. It may also assist your doctor in determining whether any damage has occurred to your spinal cord or nerve roots.
  • Electromyography (EMG) examines the musculoskeletal's electrical activity at rest and during contractions. Nerve conduction studies are frequently conducted with EMG to see whether a nerve is operating correctly. These procedures may help your doctor determine whether your symptoms are due to pressure on spinal nerve roots or injury to nerves.

Treatment for Pinched Nerve

Most patients with cervical radiculopathy get better over time and do not require therapy. The pain in some people goes away rapidly—in days or weeks. For others, intense pain may persist for more extended periods. Cervical radiculopathy that has healed usually does sometimes recur in the future. Even when this happens, it generally improves without requiring further intervention. In some situations, however, a pinched nerve does not improve. These folks must be evaluated and treated.

Nonsurgical Treatment for cervical radiculopathy

Nonsurgical treatment is always the first route to treating cervical radiculopathy. Some of those options include:

  • Soft cervical collar
  • Physical therapy
  • Medication
  • Steroid injection
  • Narcotics

What is a soft cervical collar?

A soft cervical collar is a padded ring that encircles the neck and is held in place with Velcro. Your doctor may recommend you use a soft cervical collar to allow your neck muscles to relax and restrict neck movement. This can assist decrease nerve root compression by reducing neck motion. A soft collar should only be worn for a short time since prolonged wear can weaken the muscles in the neck.

Physical therapy for cervical radiculopathy

Some specific exercises can help relieve pain, strengthen muscles in the neck, and increase a patient's range of motion. Traction can also be used in some cases to stretch the joints and muscles of the neck gently.

Which medication is helpful for a pinched nerve?

In some cases, your doctor will recommend medication to help improve your symptoms. These types of medicines are typically NSAIDs or oral corticosteroids. NSAIDs are medications like ibuprofen, naproxen, and aspirin. These can help relieve pain if it's caused by inflammation or nerve irritation. Oral corticosteroids work by reducing swelling and inflammation around the never and may help ease the pain that way.

When are steroid injections helpful?

When steroids are injected near the affected nerve, they can help to reduce local inflammation. While this may not relieve the pressure on the nerve caused by a narrow foramen or a herniated disk, steroid injections may reduce swelling and thereby relieve the pain long enough for the nerve to recover on its own.

When are narcotics recommended? 

Narcotics are only prescribed for patients with severe pain that is not relieved by any of the other options. These are usually considered for a limited time only.

Surgical Treatment for Cervical Radiculopathy

If all other treatment options have failed to relieve your symptoms, your doctor may recommend surgery. There are several procedures to treat cervical radiculopathy. Which one your doctor recommends will depend on many factors, such as which specific symptoms you are experiencing and the location of the involved nerve root.
