Cervical disc degeneration and neck pain

Area of Science:

• Orthopedics
• Neurosurgery
• Pain Management

Background:

• Cervical intervertebral disc degeneration is a frequent cause of neck pain.
• The precise mechanisms and diagnosis of discogenic neck pain are often unclear and debated.
• Degenerative cervical discs possess nerve fibers, making them susceptible to pain from stimulation or inflammation.

Purpose of the Study:

• To clarify the role of the cervical intervertebral disc in causing neck pain.
• To evaluate the diagnostic utility of cervical discography for identifying symptomatic discs.
• To discuss treatment implications for discogenic neck pain refractory to conservative management.

Main Methods:

• Review of clinical evidence linking cervical disc pathology to neck pain.
• Discussion of cervical discography as a diagnostic tool.
• Analysis of surgical outcomes for anterior cervical fusion and disc replacement.

Main Results:

• Clinical evidence suggests anterior cervical surgery rapidly alleviates neck pain in radiculopathy/myelopathy, implicating the disc.
• Cervical discography, when performed with strict criteria, can differentiate between painful and non-painful discs.
• Discogenic neck pain, independent of herniation or spondylosis, is a significant cause of chronic neck pain.

Conclusions:

• Cervical intervertebral disc degeneration is a scientifically validated cause of neck pain.
• Cervical discography is crucial for identifying symptomatic discs in refractory chronic neck pain cases.
• Anterior cervical fusion or disc replacement may offer effective solutions for patients with confirmed discogenic pain.
