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.

01:23Spinal Nerves: Anatomy
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:14Spinal Cord Injury ll: Pathophysiology
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:25Secondary Spinal Cord Injury llI: Pathophysiology
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
