Thoracic Disc Superiorly Migrated Vertical Herniation

Thoracic Disc Superiorly Migrated Vertical Herniation is a specific type of thoracic spine injury in which the inner gel-like core of the intervertebral disc (nucleus pulposus) ruptures through the outer annulus fibrosus and then tracks vertically (cranially) above the original disc level, migrating toward the pedicle of the vertebra above. This “superior migration” can compress the spinal cord or nerve roots, leading to mid-back (thoracic) pain, radiculopathy (pain radiating around the chest), or even myelopathy (spinal cord dysfunction) if severe barrowneuro.org. Though thoracic herniations are rare—accounting for less than 1% of all disc herniations—they demand prompt recognition because the thoracic canal is narrow and less forgiving than lumbar or cervical regions barrowneuro.org.

Types

1. Disc Protrusion
   The disc bulges outward without tearing the outer layer; the base (neck) remains wider than the outward bulge verywellhealth.com.

2. Disc Extrusion
   The soft center pushes fully through a tear in the outer ring, but stays connected by a narrow neck to the main disc verywellhealth.com.

3. Sequestration
   A free fragment breaks off completely and may migrate anywhere in the canal verywellhealth.com.

4. Vertical Migration (Superiorly Migrated)

   • Zone 2 (Near Up): Fragment moves just above the disc level.

   • Zone 1 (Far Up): Fragment travels well above the disc, beyond the upper vertebral body pubmed.ncbi.nlm.nih.gov.

Causes

1. Genetic Predisposition
   Variations in genes (e.g., collagen, interleukins) make some people’s discs weaker and more likely to herniate pmc.ncbi.nlm.nih.gov.

2. Age-Related Degeneration
