Cervical Transverse Nerve Root Compression at C4 – C5

Cervical transverse nerve root compression at C4–C5, often called C5 radiculopathy, occurs when the nerve fibers exiting the spinal cord between the fourth (C4) and fifth (C5) cervical vertebrae become pinched or irritated. This pressure leads to pain, numbness, or weakness along the path those nerve fibers travel—typically into the shoulder and upper arm. NCBI


Anatomy of the C5 Nerve Root

Structure & Location

The C5 nerve root begins inside the spinal canal at the level of the C4–C5 intervertebral foramen. From there, it travels outward through the bony opening (foramen) between the C4 and C5 vertebrae before branching toward muscles and skin in the shoulder region. Maryland Health Experts

Origin

These nerve fibers originate from motor (anterior horn) and sensory (posterior horn) cells in the spinal cord at the C5 segment. PMC

“Insertion” (Distribution)

Although nerves do not “insert” like muscles, the C5 root directs its motor branches into the deltoid and biceps muscles and its sensory branches into the skin over the outer shoulder and upper arm. Orthobullets

Blood Supply

Small radicular arteries—branches of the ascending cervical artery (from the thyrocervical trunk) and the deep cervical artery (from the costocervical trunk)—run alongside the C5 root through the foramen, delivering oxygen-rich blood. Turkish Neurosurgery

Nerve Supply

The C5 root itself carries both motor fibers (to muscles) and sensory fibers (from skin) as well as sympathetic (autonomic) fibers that help regulate blood vessel tone. PM&R KnowledgeNow

Key Functions

  1. Deltoid Muscle Movement: Lifts your arm away from your body (abduction).

  2. Biceps Muscle Contraction: Helps bend your elbow (flexion).

  3. Shoulder Sensation: Feels touch and temperature over the outer shoulder.

  4. Arm Proprioception: Sends position-sense signals from shoulder muscles back to the brain.

  5. Reflex Response: Triggers the biceps tendon reflex when the muscle is tapped.

  6. Sympathetic Regulation: Contributes to blood vessel control in the shoulder region. PM&R KnowledgeNow


Types of C4–C5 Nerve Root Compression

  1. Acute Traumatic: Sudden compression from injury (e.g., whiplash).

  2. Degenerative (Spondylosis): Wear-and-tear bone spurs narrow the foramen.

  3. Disc Herniation: Rupture of the disc between C4 and C5 pushes on the root.

  4. Foraminal Stenosis: Chronic narrowing of the neural exit due to arthritic change.

  5. Osteophyte Formation: Bony growths pinch the nerve over time.

  6. Ligament Thickening: Hypertrophy of the ligamentum flavum crowds the foramen.

  7. Tumors: Benign or malignant growths inside or beside the foramen.

  8. Infection/Abscess: Inflammation from infections can compress the root.

  9. Inflammatory Arthritis: Rheumatoid changes narrow the nerve exit.

  10. Iatrogenic: Post-surgical scarring or hardware misplacement causes compression.


Causes

  1. C4–C5 Disc Herniation: Gel-like disc material bulges into the nerve exit.

  2. Cervical Spondylosis: Age-related disc drying and bone spur formation.

  3. Foraminal Osteophytes: Bony outgrowths crowd the nerve channel.

  4. Hypertrophic Ligamentum Flavum: Ligament thickening reduces space.

  5. Cervical Spinal Stenosis: Generalized narrowing of the spinal canal.

  6. Facet Joint Hypertrophy: Enlarged joints press laterally on the root.

  7. Traumatic Whiplash: Sudden neck extension-flexion injures root.

  8. Cervical Fracture: Bone fragments impinge on the nerve.

  9. Tumor in Foramen: Benign (e.g., schwannoma) or malignant growth.

  10. Epidural Abscess: Pus formation compresses the root.

  11. Rheumatoid Arthritis: Synovial inflammation and pannus formation.

  12. Metastatic Cancer: Cancer spread to vertebrae encroaches the foramen.

  13. Congenital Narrowing: Birth defect of a small neural foramen.

  14. Atlantoaxial Instability: Excessive movement reduces space at C4–C5.

  15. Ossification of PLL: Posterior longitudinal ligament turns to bone.

  16. Post-Operative Scar Tissue: Surgical healing leads to fibrous bands.

  17. Cervical Disc Calcification: Disc tissue hardens and presses outward.

  18. Cervical Disc Bulge: Non-herniated but protruding disc edge.

  19. Vertebral Artery Loop: Vascular anomaly presses on the nerve root.

  20. Paget’s Disease: Abnormal bone remodeling narrows exit.

The above causes are among the most commonly identified in cervical radiculopathy NCBIPMC

When to See a Doctor

  • Severe Arm Weakness or Numbness: Especially if it worsens rapidly.

  • Loss of Bladder or Bowel Control: A medical emergency.

  • Unrelenting Night Pain: Pain that prevents all sleep despite treatment.

  • Progressive Muscle Wasting: Visible shrinkage in shoulder or arm muscles.

  • Failed Conservative Care: No improvement after 6–8 weeks of therapy.

  • Signs of Infection: Fever, chills, or redness over the spine.


Frequently Asked Questions

  1. What exactly is C5 radiculopathy?
    It’s when the nerve root at C4–C5 is pinched, causing neck and arm problems.

  2. Can it get better on its own?
    Many mild cases improve with therapy, posture changes, and time over weeks to months.

  3. Is MRI always needed?
    If simple tests don’t help or you have serious weakness, an MRI is the best next step.

  4. Will physical therapy fix it?
    Yes—targeted exercises, posture training, and hands-on care can relieve pressure.

  5. Are steroids safe?
    A short course of oral steroids or a single epidural injection is usually well tolerated.

  6. When is surgery necessary?
    If severe weakness or nerve damage shows up on tests or you don’t improve after 6–8 weeks.

  7. What are the risks of surgery?
    Infection, bleeding, nerve injury, difficulty swallowing (rare), and non-fusion.

  8. Can I exercise with a pinched nerve?
    Gentle, guided exercise is safe; avoid heavy lifting or sudden neck twists.

  9. Are there home remedies that help?
    Ice, heat, rest, gentle neck stretches, and over-the-counter pain relievers can ease symptoms.

  10. What is the prognosis?
    Most people recover fully with conservative care; surgery has high success rates when needed.

  11. Can this cause permanent damage?
    Rarely—only if left untreated with progressive nerve damage.

  12. Is it related to aging?
    Yes—degenerative changes in the spine make nerve compression more likely over age 40.

  13. How long does recovery take?
    Weeks to months for mild cases; post-surgical recovery may take 3–6 months.

  14. Will it come back?
    Good posture and regular exercise lower the risk, but degenerative changes can recur.

  15. Can stress make it worse?
    Yes—muscle tension from stress can tighten neck muscles and worsen compression.
