Cervical Transverse Nerve Root Compression

Cervical Transverse Nerve Root Compression—often called cervical radiculopathy or a “pinched nerve in the neck”—occurs when one or more nerve roots exiting the cervical spinal cord are pressed upon by surrounding structures. This compression disrupts normal nerve signaling, leading to pain, numbness, tingling, or weakness in the shoulder, arm, or hand. It can arise suddenly (e.g., from trauma) or develop gradually (e.g., due to age-related spine changes). UpToDatePMC

Anatomy of Cervical Nerve Roots

The cervical spine (neck) has seven vertebrae (C1–C7) but eight pairs of nerve roots (C1–C8). Each nerve root emerges laterally through an intervertebral foramen just above its corresponding vertebra (the C8 root exits between C7 and T1). Spine-health

1. Structure

   • Formed by the merging of a dorsal (sensory) root and ventral (motor) root immediately after they leave the spinal cord.

   • These two roots join within the foramen to become a mixed spinal nerve.

2. Location

   • Cervical nerve roots lie just lateral to the vertebral bodies, protected by facet joints and uncovertebral joints (of Luschka).

3. Origin

   • Motor fibers arise from anterior horn cells of the spinal cord.

   • Sensory fibers originate in the dorsal root ganglion, a collection of sensory neuron cell bodies just outside the spinal cord.

4. Insertion/Continuation

   • After exiting the foramen, each mixed spinal nerve divides into ventral rami (forming the brachial plexus for C5–T1) and dorsal rami (supplying deep neck muscles and skin).

5. Blood Supply

   • Radicular arteries (branches of the vertebral artery or ascending cervical artery) run alongside nerve roots within the foramen to nourish both roots. NCBI

6. Nerve Supply

   • Each root carries both afferent (sensory) and efferent (motor) fibers that serve specific dermatomes (skin zones) and myotomes (muscle groups).

Key Functions

1. Motor Control: Carries impulses to muscles (e.g., C5–C6 roots activate biceps for elbow flexion).

2. Sensory Conduction: Transmits touch, pain, temperature, and vibration from neck, shoulder, arm, and hand.

3. Reflex Arcs: Mediates deep tendon reflexes (e.g., biceps reflex via C5–C6, triceps via C7).

4. Proprioception: Provides sense of joint position and movement in cervical and upper limb segments.

5. Autonomic Modulation: Contains sympathetic fibers that regulate blood flow and sweat glands in the upper extremity.

6. Pain Signaling: Conducts nociceptive signals when irritated or compressed, perceived as radiating pain. WikipediaVerywell Health

Types of Compression

Cervical nerve root compression can be classified by location, timing, and cause: NCBIPMC

• By Location

  • Foraminal (in the intervertebral foramen)

  • Extraforaminal (beyond the foramen)

Frequently Asked Questions

1. What is Cervical Transverse Nerve Root Compression?
   It’s compression of a nerve root in the neck, impairing signal transmission and causing pain or neurologic deficits. PMCUpToDate

2. How common is it?
