Cervical Disc Herniation
A herniated disc in the neck causing arm pain, numbness, or weakness
Cervical disc herniation occurs when the nucleus pulposus — the soft inner material of a cervical intervertebral disc — herniates through the outer annular ring and compresses one or more cervical nerve roots. This typically causes radiculopathy: pain, numbness, or weakness radiating from the neck into the shoulder, arm, and hand in a specific pattern corresponding to the affected nerve root. Cervical herniations are most common at C5–6 and C6–7. While lumbar herniations are more common overall, cervical herniations can be more functionally disabling due to involvement of the arm and hand.
Symptoms
- Neck pain with radiation into the shoulder, arm, and hand (cervical radiculopathy)
- Numbness or tingling in the fingers, following a dermatomal pattern (e.g., thumb and index finger for C6)
- Hand or arm weakness — difficulty gripping, holding objects, or lifting
- Pain that worsens with turning the head toward the affected side or extending the neck
- Headaches at the base of the skull
- In severe cases: bilateral arm weakness, hand clumsiness, or walking difficulty (signs of myelopathy — seek urgent evaluation)
Causes & Risk Factors
- Age-related disc degeneration causing loss of disc height and annular weakening
- Acute trauma such as motor vehicle accident or sports impact
- Repetitive strain from prolonged flexed-neck posture (desk work, phone use)
- Sudden cervical loading (heavy lifting, impact sports)
- Genetic predisposition to early disc degeneration
Treatment Options
Conservative (Non-Surgical)
- Physical therapy targeting cervical stabilization and posture correction
- NSAIDs and short courses of oral corticosteroids for acute flares
- Cervical traction (mechanical or manual) to decompress the nerve root
- Cervical epidural steroid injection to reduce nerve root inflammation
- Soft cervical collar for brief periods only (prolonged use weakens neck muscles)
- Activity modification and ergonomic adjustments
Surgical Options
- Anterior Cervical Discectomy and Fusion (ACDF) — the most common surgical approach: removes the herniated disc from the front, decompresses the nerve, and fuses adjacent vertebrae
- Cervical Disc Replacement (arthroplasty) — alternative to fusion that preserves motion at the treated level; ideal for younger patients without significant arthritis
- Posterior Cervical Foraminotomy — a keyhole procedure from the back of the neck to widen the foramen and relieve nerve compression without fusion; best for lateral disc herniations
When to see a spine specialist
See a spine specialist if arm pain, numbness, or weakness has not improved after 4–6 weeks of conservative care. Seek urgent evaluation if you develop hand clumsiness, difficulty walking, or balance problems — these may indicate cervical myelopathy (spinal cord compression) which can cause permanent neurological injury if not treated promptly. Go to the emergency room if you develop sudden weakness in both arms or legs.
Frequently Asked Questions
How is cervical disc herniation different from lumbar herniation?
Both involve disc material pressing on nerves, but location determines symptoms. Lumbar herniations compress nerve roots causing leg pain (sciatica), foot numbness, and lower extremity weakness. Cervical herniations compress neck nerve roots causing arm and hand pain, numbness, and weakness. Cervical herniations also carry the additional risk of myelopathy — spinal cord compression — which can cause widespread neurological deficits if left untreated.
What does cervical radiculopathy feel like?
Cervical radiculopathy typically produces sharp, burning, or electric pain starting at the neck and radiating into the shoulder, upper arm, forearm, and hand. Numbness and tingling follow a dermatomal pattern — C6 affects the thumb and index finger; C7 affects the middle finger; C8 affects the ring and small fingers. Weakness follows a myotomal pattern, such as biceps weakness with C5 involvement or wrist extension weakness with C7.
When is surgery needed for cervical disc herniation?
Surgery is indicated when: (1) progressive neurological deficits are present (worsening weakness or numbness), (2) conservative care has failed after 6–12 weeks, (3) pain is severe and disabling, or (4) myelopathy (spinal cord compression) is present or progressing. The majority of cervical disc herniations improve without surgery — approximately 80–90% resolve or become tolerable with conservative management within 3 months.
What is the recovery time after ACDF surgery?
Most ACDF patients are discharged home the same day or after one night. Return to desk work typically takes 2–4 weeks. Driving is restricted for 2–4 weeks. Physical labor or contact sports restriction is typically 3–6 months. A cervical collar is worn for 2–6 weeks. Fusion is confirmed with X-rays at 3–6 months. The majority of patients experience significant arm pain relief within weeks of surgery.
