CERVICAL RADICULOPATHY

Cervical Radiculopathy often refers to a “pinched nerve”. To frequently, this condition can cause pain to radiate away from the neck. Furthermore, disc herniation, bone spurs can also cause cervical radiculopathy.

Cervical Radiculopathy

Cervical radiculopathy occurs when a nerve in the neck becomes irritated as it leaves the spinal canal. Commonly thought of as a “pinched nerve,” cervical radiculopathy stems from a herniated disc or a bone spur that presses against an inflamed nerve root. Unfortunately, this problem occurs as a result of degenerative changes in the neck.

Anatomy

In order to understand your symptoms and treatment choices, patients should learn and understand the anatomy of the neck. In addition, this includes becoming familiar with the various parts that make up the cervical spine and how they work together.

Cervical Radiculopathy (“Pinched Nerve”) Causes

Nerve roots that go from the spinal cord in the cervical spine travel into the arm. Along the way, these nerves supply sensation (feeling) to areas of the skin from the shoulder to the fingers.  Additionally, they also carry electrical signals to muscles that move the arm, hand, or fingers. Meanwhile, problems occur when one of these nerves becomes inflamed and pinched by a herniated disc or bone spur. For example, this may show up as a weakness, numbness, and pain where the nerve travels. To clarify, the pain may feel deep, dull, and achy, or you may have sharp, shooting pain along the path of the nerve. Muscles controlled by the affected nerve root may also weaken. In the neck, this condition refers to a term called cervical radiculopathy.

Disc Herniation

When the neck moves, it generates tension and pressure to the spine.  Therefore, the disc between each vertebra responds by acting as a shock absorber. Additionally, bending the neck forward compresses the discs between the vertebrae and tends to bulge the discs backward toward the spinal canal and nerve roots.

Problems may occur when the center part of the disc, the nucleus pulposus, squeezes out of the disc and puts pressure on nerves in the neck. To explain, this condition, called disc herniation, can happen when a tear in the outer ring of the disc (the annulus) allows the nucleus to squeeze through. For example, the annulus can tear or rupture anywhere around the disc. If it tears next to the spinal canal, the nucleus can squeeze out and put pressure on the spinal cord or spinal nerves. To further explain, pressure against the nerve root from a herniated disc can cause numbness and weakness along the nerve. When the nerve root becomes inflamed, the added pressure from the disc may also cause vague, deep pain in the neck, shoulder, and upper arm. It can also cause sharp, shooting pain to radiate along the pathway of the nerve.

This condition may occur when too much force is exerted on an otherwise healthy intervertebral disc. Heavy forces on the neck may injure healthy discs.

Herniated discs are more common in middle-aged adults because of the natural process of aging.  Unfortunately, this causes the discs to become weakened from degeneration, and less force causes herniation.  Although, not everyone with a herniated disc has degenerative problems. Likewise, not everyone with degeneration will suffer a herniated disc.

Bone Spurs

In older people, degenerative disc disease can cause bone spurs to form near the nerve roots. If these bone spurs get big enough, they may begin to rub on the nerve root and irritate it. This usually occurs inside the foramina, which are small openings on each side of the spinal column where the nerve roots leave the spine. An irritated nerve root, squeezed by a bone spur, can cause the same symptoms as a herniated disc in the neck pain, numbness, and weakness in the arm.

Symptoms

Cervical radiculopathy causes symptoms that radiate away from the neck. Although the problem exists in the neck, the symptoms will occur wherever the nerve travels — shoulder, arm, or hand. By locating the symptoms, your doctor can usually tell which nerve in the neck is affected. Symptoms generally include pain, numbness, and weakness. The reflexes in the upper arm can also be affected. Neck pain and headaches near the back of the head are common with cervical radiculopathy. The back of the head refers to a medical term called the occiput, which explains why headaches in this area are called occipital headaches.

Diagnosis

Finding the cause of your neck problem begins with a complete history and physical exam. After the history and physical exam, the doctor may have a good idea of the cause of your pain or other symptoms. To make sure of the exact cause of your neck pain, several diagnostic tests can be used. These tests are used to find the cause of the pain, not make it better. Standard X-rays are usually a first step in looking into any neck problem. These include an oblique (angled) view, along with X-rays taken as you bend forward (flexion) and backward (extension). Your doctor will also determine whether other tests, such as an MRI, are needed.

Treatment Options

[Conservative Treatment]

Medication

Medications are commonly used to control pain, inflammation, muscle spasm, and sleep disturbance.

Cervical Collar

The cervical collar supports and limits motion while an injured neck healsg. It also helps keep the proper alignment. Cervical collars can be soft (made of foam) or hard (plastic). Because these collars can restrict head movement, you may need help with eating or other activities. The skin under the collar needs checking every day to prevent blisters or sores.

Cervical Pillow

A special pillow may help ease your pain at night and allow you to sleep better. Cervical pillows are specially designed to place the right amount of curvature in the neck while you sleep and to decrease the amount of irritation on the nerve roots. These pillows can be purchased from drug stores or from a physical therapist.

Physical Therapy

Your doctor may have you work with a physical therapist. A well-rounded rehabilitation program assists in calming pain and inflammation, improving your mobility and strength, and helping you do your daily activities with greater ease and ability.

Therapists use cervical traction to gently stretch the neck and to relieve pressure on the irritated nerve root. Electrical stimulation eases muscle spasms and pain. Exercises focus on improving the strength and coordination of the neck, shoulders, and upper back. Therapy sessions may be scheduled two to three times each week for up to six weeks.
The goals of physical therapy are to help you

  • Learn correct posture and body movements to reduce neck strain
  • Maintain appropriate activity levels
  • Maximize your neck range of motion and strength
  • Learn ways to manage your condition

ESI

If other treatments do not relieve your neck pain, you may be given an epidural steroid injection (ESI), also called a nerve block. An ESI places a small amount of cortisone into the bony spinal canal. Cortisone may control the inflammation surrounding the nerves and may ease the pain caused by irritated nerve roots. This injection works when other conservative measures do not. This treatment does not always provide a successful remedy, but may provide short-term help. 

Surgical Treatment

Cervical radiculopathy doesn’t always improve with conservative care.  When the following conditions are present, your doctor may recommend surgery:

  • Unbearable pain that doesn’t respond to medical management
  • Unacceptable weakness
  • Weakness that is progressing
  • Evidence of spinal cord compression
  • Bowel or bladder concerns

One of the most common operations used to treat cervical radiculopathy caused by pressure from bone spurs and a herniated disc is an anterior cervical fusion.
After surgery, you may be placed in some type of neck brace for up to 12 weeks while healing. Learn more about braces used to treat neck problems.
