Cervical Radiculopathy
Cervical radiculopathy is a pinched or irritated nerve in the neck that can cause pain, numbness, tingling, or weakness radiating into the shoulder, arm, or hand.
Quick Answer
Cervical radiculopathy is a pinched nerve in the neck that produces pain, numbness, tingling, or weakness radiating along the path of that nerve into the shoulder, arm, or hand. It is usually caused by a herniated disc or by bone spurs from age-related degeneration narrowing the space where the nerve exits the spine. Most cases improve with non-surgical care, and surgery is reserved for persistent symptoms or significant weakness.
Key Takeaways
- Cervical radiculopathy occurs when a nerve root in the neck becomes compressed or irritated.
- Symptoms often follow the path of the affected nerve into the shoulder, arm, or hand.
- Common causes include a herniated disc or bone spurs from cervical degeneration.
- Most patients improve with nonsurgical treatment.
- Persistent pain or progressive weakness may require surgical evaluation.
At a Glance
| What it is | Compression or irritation of a nerve root in the neck |
|---|---|
| Common causes | Herniated disc, bone spurs, or degenerative narrowing |
| Common levels | C6 and C7 nerve roots |
| Typical symptoms | Radiating arm pain, numbness, tingling, or weakness |
| First-line treatment | Physical therapy, anti-inflammatory medication, and activity modification |
| Surgical options | ACDF, cervical disc replacement, or posterior cervical foraminotomy |
Symptoms
Cervical radiculopathy typically causes pain that radiates from the neck into the shoulder, arm, or hand, along with numbness or tingling in a specific pattern that depends on which nerve root is affected. Some patients notice weakness in particular arm or hand muscles. The distribution of symptoms, including which fingers feel numb, helps the physician identify the involved level.
Symptoms often change with neck position. Many patients find that raising the arm overhead and resting the hand on top of the head reduces the pain, a phenomenon known as the shoulder abduction sign, because it takes tension off the nerve. Coughing, sneezing, or certain neck movements may worsen the radiating pain.
Common Warning Signs
- Pain radiating from the neck into the shoulder, arm, or hand
- Numbness or tingling in specific fingers
- Weakness in the arm, hand, or grip
- Symptoms that worsen with certain neck movements
- Relief when resting the hand on top of the head
When to Seek Care Promptly
- Progressive weakness in the arm or hand
- New hand clumsiness or difficulty with fine motor tasks
- Balance or walking difficulty
- Symptoms affecting both arms
- Loss of bladder or bowel control
Diagnosis
Diagnosis begins with a history and neurological examination assessing strength, sensation, reflexes, and how symptoms travel through the shoulder, arm, and hand. Certain examination maneuvers, such as the Spurling test, may help identify an irritated or compressed cervical nerve root.
MRI is typically the most useful imaging study because it can identify a herniated disc, bone spur, or narrowing that is compressing the nerve root. When symptoms and imaging do not clearly identify the source, EMG and nerve conduction studies may help distinguish cervical radiculopathy from conditions such as carpal tunnel syndrome or other peripheral nerve problems.
Treatment
Most cervical radiculopathy improves without surgery. Initial treatment may include physical therapy, activity modification, anti-inflammatory or other medications, and sometimes a cervical epidural steroid injection to reduce inflammation around the affected nerve.
Surgery may be considered when arm pain persists despite appropriate nonsurgical treatment or when there is significant or progressive weakness. Depending on the location and cause of nerve compression, options may include anterior cervical discectomy and fusion (ACDF), cervical disc replacement, or posterior cervical foraminotomy.
At Atlantic Brain and Spine, the surgical approach is individualized based on where the nerve is compressed, the condition of the affected disc and surrounding levels, spinal alignment, and whether preserving motion is appropriate.
The Diagnosis-to-Treatment Pathway
1. Clinical evaluation
History and neurological examination help identify the affected cervical nerve root.
2. Conservative care
Physical therapy, activity modification, and medication are typically the first approach.
3. Imaging
MRI identifies a herniated disc, bone spur, or narrowing that may be compressing the nerve root.
4. Nerve testing if needed
EMG and nerve conduction studies may help distinguish cervical radiculopathy from peripheral nerve conditions.
5. Targeted injection
A cervical epidural steroid injection may be considered for persistent radiating arm pain in selected patients.
6. Surgical evaluation
Persistent pain or progressive weakness may prompt evaluation for surgical decompression.
7. Surgical decompression
ACDF, cervical disc replacement, or posterior cervical foraminotomy may relieve persistent nerve compression.
8. Recovery
Rehabilitation focuses on restoring function and reducing strain on the cervical spine.
Frequently Asked Questions
The two most common causes are a herniated disc, in which soft disc material presses on the nerve, and bone spurs from age-related degeneration that narrow the opening where the nerve exits the spine. Both irritate or compress the nerve root and produce radiating arm symptoms.
Raising the arm and placing the hand on top of the head reduces tension on the compressed nerve root, often easing the radiating pain. This shoulder abduction sign is a recognized feature of cervical radiculopathy and can support the diagnosis.
Frequently, yes. Many patients improve within several weeks with conservative care as the nerve irritation settles. Surgery is considered when symptoms persist despite treatment or when weakness is significant or worsening.
A posterior foraminotomy enlarges the bony opening where the nerve exits, relieving compression while preserving the disc and motion. An ACDF removes the disc from the front of the neck and fuses the segment. The choice depends on the location and cause of the compression, decided through the spine board.
Possibly, and the two can coexist. Carpal tunnel syndrome compresses a nerve at the wrist, while cervical radiculopathy compresses it at the neck. The pattern of numbness and the results of nerve testing help distinguish them, which is important because the treatments differ.
Cervical spine surgery is well established and generally safe in experienced hands. As with any surgery there are risks, which your surgeon will review. At Atlantic Brain and Spine, cases are planned through a spine board so the approach is tailored to your anatomy.
