Cervical inferiorly migrated nerve root compression is a form of cervical radiculopathy where a piece of disc material (a sequestered fragment) moves downward (inferiorly) from its original level and presses on a cervical nerve root one level below. This can lead to neck pain, arm pain, numbness, and weakness along the path of the affected nerve. Most cases arise from degenerative changes in the cervical spine and often improve with time and conservative care, but some require more advanced treatments. SpringerOpenSpine-health
Anatomy
Cervical nerve roots are the very beginnings of the nerves that carry messages between your spinal cord and the rest of your body. They:
-
Originate as small bundles of rootlets on the spinal cord at levels C1 through C8.
-
Exit the spinal canal through openings called intervertebral foramina at each level of the neck.
-
Merge dorsal (sensory) and ventral (motor) rootlets into a single spinal nerve right outside the foramen Spine-healthNCBI.
-
Receive blood from segmental radicular arteries branching off the vertebral and ascending cervical arteries, plus tiny vessels (vasa nervorum) within their coverings NCBI.
-
Carry both sensory fibers (for touch, pain, temperature, joint position) and motor fibers (to control muscles), as well as some autonomic fibers that help regulate blood flow and glands Spine-healthTeachMeAnatomy.
Key Functions
-
Sensory Transmission: Carries touch, pain, temperature signals from skin and deeper tissues.
-
Motor Control: Sends commands for voluntary muscle movement, e.g., shoulder elevation or elbow flexion.
-
Proprioception: Relays information about joint and muscle position for balance and coordination.
-
Autonomic Regulation: Influences blood vessel dilation and gland secretions in the head, neck, and upper limbs.
-
Reflex Arcs: Participates in quick, automatic responses such as the biceps and triceps reflexes.
-
Pain Perception: Transmits nociceptive (pain) signals when irritated or compressed Spine-healthNCBI.
Types of Cervical Nerve Root Compression
-
Protrusion: Disc bulge without annular tear, causing mild compression.
-
Extrusion: Inner disc material pushes through a tear in the annulus fibrosus.
-
Sequestration (Free Fragment): A fragment breaks away and may migrate upward or downward Radsource.
-
Subligamentous Sequestration: Disc material moves under the posterior longitudinal ligament.
-
Transligamentous Sequestration: Disc material breaches the posterior longitudinal ligament entirely.
-
Central vs. Paracentral vs. Foraminal vs. Extraforaminal: Based on where the disc fragment presses—center, just off-center, within the foramen, or beyond it.
-
Inferiorly Migrated Herniation: The fragment shifts downward, pressing on the nerve root below its original disc level.
Causes
-
Age-Related Degeneration: Disc wear and tear over time weaken its structure.
-
Annular Tear: A small tear in the disc’s outer ring lets inner gel escape.
-
Osteoarthritis (Spondylosis): Bone spurs narrow foramina.
-
Facet Joint Hypertrophy: Enlarged joints pinch nerve roots.
-
Ligamentum Flavum Thickening: Ligament bulges into the canal or foramen.
-
Poor Posture: Constant forward head position adds stress.
-

Trauma: Car accidents or falls can tear discs or spur bone fragments.
-
Rheumatoid Arthritis: Inflammation erodes joints and ligaments.
-
Synovial Cysts: Fluid-filled sacs in facet joints compress roots.
-

Infections: Abscesses or discitis can press on roots.
-
Iatrogenic Causes: Scar tissue from surgery (post-laminectomy syndrome).
-
Disc Calcification: Hardening of disc material reduces flexibility.
-
Metabolic Disorders: Conditions like diabetes may predispose to nerve injury.
-
Chemical Radiculitis: Inflammatory chemicals from disc material irritate roots.
