Cervical Spondylosis: Causes, Symptoms, Diagnosis & Treatment- By Dr. Balaraju Naidu, Robotic Orthopedic Surgeon, ONUS Robotic Hospitals

Cervical Spondylosis is one of the most common age-related spine conditions affecting the neck region. It occurs due to gradual wear and tear of the cervical spine, including the discs, joints, ligaments, and bones.

Many people experience occasional neck pain, but when the cervical discs and joints degenerate, it can lead to chronic pain, stiffness, nerve compression, tingling, numbness, and weakness in the arms or hands.

At ONUS Robotic Hospitals, Dr. Balaraju Naidu and the spine care team provide advanced diagnosis and treatment for cervical spine disorders using modern imaging, rehabilitation, and minimally invasive treatment approaches.

What is Cervical Spondylosis?

The cervical spine consists of seven vertebrae in the neck region that support head movement and protect the spinal cord.

With aging and continuous stress on the neck:

• Intervertebral discs lose hydration
• Disc height decreases
• Bone spurs (osteophytes) may develop
• Ligaments become stiff
• Nerves may get compressed

This degenerative process is known as Cervical Spondylosis.

It is commonly seen after the age of 40 but can occur earlier due to poor posture, prolonged screen time, desk jobs, or repetitive strain.

Common Symptoms of Cervical Spondylosis

Symptoms can vary depending on the severity of degeneration and nerve involvement.

Common Symptoms Include:

👉 Neck pain and stiffness
👉 Shoulder pain
👉 Pain radiating into the arms
👉 Tingling sensation in hands
👉 Numbness in fingers
👉 Weakness in arms or grip strength
👉 Headaches starting from the neck
👉 Dizziness or imbalance
👉 Reduced neck movements

Some patients may also experience muscle spasms and difficulty performing daily activities.

Causes & Risk Factors

Several factors contribute to Cervical Spondylosis.

Common Causes Include:

✔ Age-Related Wear & Tear

Natural degeneration of discs and joints over time.

✔ Poor Posture

Long hours using mobile phones, laptops, or computers can strain the neck muscles and discs.

✔ Sedentary Lifestyle

Lack of exercise weakens spinal support muscles.

✔ Previous Neck Injury

Past trauma may accelerate degeneration.

✔ Repetitive Neck Movements

Continuous strain from driving, office work, or certain occupations.

✔ Obesity & Muscle Weakness

Excess body weight and weak muscles increase spinal stress.

How Does Nerve Compression Occur?

As the cervical discs degenerate:

• Disc bulges may develop
• Bone spurs can narrow nerve passages
• Spinal canal narrowing may occur

This can compress nearby nerves or even the spinal cord.

Nerve compression may cause:

• Tingling
• Numbness
• Weakness
• Burning pain radiating to the shoulders or hands

In severe cases, patients may experience balance problems or difficulty walking.

Diagnosis of Cervical Spondylosis

Early diagnosis helps prevent worsening symptoms and nerve damage.

Clinical Examination

Doctors assess:

• Neck movements
• Muscle strength
• Reflexes
• Sensation in arms and hands
• Signs of nerve compression

Imaging Tests

✔ X-Ray

Shows:

• Disc space narrowing
• Bone spurs
• Degenerative changes

✔ MRI Scan

MRI is the best investigation to identify:

• Disc bulges
• Nerve compression
• Spinal cord involvement
• Soft tissue damage

✔ CT Scan (In Selected Cases)

Useful for evaluating bone structures in detail.
