Traumatic neuropathy of second cervical spinal nerves
British Medical Journal (Clinical Research Ed.)
|April 23, 1983
Summary
Second cervical spinal nerves are susceptible to injury from atlas and axis movements, causing sensory issues and balance problems. Most cases of this cervical neuropathy resolve naturally within 1-3 years.
Area of Science:
- Neurology
- Spinal Cord Anatomy
Background:
- The second cervical spinal nerves (C2) are anatomically positioned near the atlas (C1) and axis (C2) vertebrae.
- These nerves are susceptible to injury due to the biomechanics of the upper cervical spine.
Observation:
- Forcible approximation of the atlas and axis arches can compromise the second cervical nerves.
- Excessive rotation of the atlas on the axis is another mechanism leading to nerve vulnerability.
Findings:
- Injuries to the second cervical nerves result in sensory disturbances, including hypoesthesia (loss of feeling) and neuralgia (nerve pain).
- Neuropathy of the second cervical nerves can manifest as disorders of balance.
Implications:
- Diagnosis can be challenging, particularly in cases with concurrent multiple cervical spine injuries.
- Prognosis is generally favorable, with spontaneous resolution of symptoms typically occurring within one to three years.
