Cervical radiculopathy
Cervical radiculopathy refers to the inflammation or compression of a nerve root located in the cervical spine, leading to alterations in neurological function. This condition often presents with neurological deficits such as numbness, changes in reflexes, or weakness, which can extend from the neck to the shoulder, arm, hand, or fingers. Individuals may also experience pins-and-needles tingling sensations and varying degrees of pain, ranging from dull and achy to sharp, shock-like, or burning, which may radiate down the arm and into the hand. Understanding the symptoms associated with cervical radiculopathy is crucial for timely diagnosis and effective management of the condition.
Symptoms of cervical radiculopathy
Cervical radiculopathy can lead to various neurological deficits that affect the neck, shoulder, arm, hand, and fingers. These deficits may include:
Sensory changes: Individuals may experience sensations of numbness, reduced sensation in the skin, or tingling, often described as electrical sensations.
Motor impairments: Weakness or diminished coordination in one or more muscles may occur as a result of cervical radiculopathy.
Recognizing and understanding these neurological deficits associated with cervical radiculopathy is crucial for accurate diagnosis and appropriate management of the condition
Causes of cervical radiculopathy
Cervical radiculopathy can stem from various underlying causes, including:
Degenerative Changes: Normal wear and tear in the discs of the cervical spine, often observed in middle-aged individuals, can lead to pressure on nerve roots. For instance, cervical foraminal stenosis occurs when degenerative changes narrow the openings in the vertebrae, resulting in the compression of nerve roots.
Injury: Younger individuals may experience cervical radiculopathy due to a ruptured disc, often resulting from trauma. Disc herniation commonly occurs during activities such as bending, lifting, twisting, or pulling. When a disc herniates, its material can compress or inflame the nerve root, causing pain and other symptoms.
Other less common causes of cervical radiculopathy may include:
Infections in the Spine
Spinal Tumors, either cancerous or benign growths
Sarcoidosis: This condition involves the growth of inflammatory cells in the spine.
Risk factors for cervical radiculopathy
-
Certain factors can heighten the risk of developing cervical radiculopathy, including:
Age: The likelihood of cervical radiculopathy tends to rise with age, with the risk peaking in a person's 40s or 50s. As individuals age, changes in the cervical spine become more common.
Engagement in Strenuous Activities: Activities that exert significant stress on the cervical spine, such as wrestling or weight-lifting, may increase the risk of cervical radiculopathy.
Repetitive Neck Motions or Vibrations: Regular exposure to repetitive neck motions or vibrations, such as those experienced while driving a truck with vibrating equipment or repeatedly diving headfirst into a pool, can contribute to the development of cervical radiculopathy.
Additionally, several other risk factors may also elevate the likelihood of cervical radiculopathy, including smoking or a history of lumbar radiculopathy.
Diagnosis of cervical radiculopathy
To diagnose cervical radiculopathy, Dr. Vivek Badhe will initiate the assessment by thoroughly evaluating your symptoms and medical history. A comprehensive physical examination will be conducted, focusing on your neck, shoulders, arms, and hands to identify any muscle weakness, sensory abnormalities, or reflex issues.
During the examination, he may request you to perform various movements of your arms or neck to observe how they affect your symptoms, particularly pain or discomfort.
Furthermore, diagnostic tests may be recommended, including:
X-rays: These imaging tests can reveal any narrowing of vertebral openings or potential disk injuries in the cervical spine.
CT scans: This imaging technique provides detailed images of the cervical spine, enabling healthcare providers to assess the structures more comprehensively.
MRI: Magnetic Resonance Imaging is particularly useful for detecting damage to nerve roots or soft tissues in the cervical spine.
Electromyography (EMG): EMG assesses muscle function by measuring electrical activity when muscles are at rest and contracted, aiding in the evaluation of nerve and muscle abnormalities.
Treatment of cervical radiculopathy
-
Nonsurgical approaches are typically the first line of treatment for cervical radiculopathy, often involving medications, physical therapy, or a combination of both.
Medications: Your healthcare provider may prescribe medications such as corticosteroids, which are potent anti-inflammatory drugs, or nonsteroidal pain relievers like ibuprofen or naproxen to alleviate pain and reduce inflammation. Steroids can be administered orally or through epidural injections, which involve injecting medication into the space around the dura, the membrane surrounding the spinal cord.
Physical Therapy: Physical therapy interventions may include gentle cervical traction and mobilization techniques, targeted exercises, and various modalities aimed at alleviating pain and improving mobility.

In cases where there is significant nerve compression leading to motor weakness, surgical intervention may be necessary to alleviate pressure on the affected nerve and restore function. However, surgical treatment is typically considered only when conservative measures fail to provide relief or when symptoms worsen despite nonsurgical interventions.
