Cervical C7–T1 Vertical Herniation

Cervical C7–T1 vertical herniation, also known as a Schmorl’s node at the cervicothoracic junction, occurs when nucleus pulposus material extrudes vertically through defects in the cartilaginous and bony endplate of the C7–T1 intervertebral disc into the adjacent vertebral body. Unlike the more common posterolateral disc herniations that compress spinal nerves, vertical herniations predominantly involve intravertebral migration of disc tissue. While frequently asymptomatic and discovered incidentally on imaging, they can sometimes lead to localized pain, vertebral endplate inflammation, and, rarely, radiculopathy or myelopathy if significant structural compromise occurs OsmosisRadiopaedia.

C7–T1 vertical herniation refers to a protrusion or extrusion of the intervertebral disc located between the seventh cervical (C7) and first thoracic (T1) vertebrae. Although cervical disc herniations most commonly occur at C5–6 or C6–7, those at C7–T1 are rare—accounting for only 4–8% of all cervical herniations—and often present unique clinical challenges Journal of Turkish Spinal Surgery. In a C7–T1 herniation, the nucleus pulposus (the gel-like center of the disc) breaches the annulus fibrosus (tough outer ring), potentially compressing the C8 nerve root. This can lead to neck pain, shoulder girdle discomfort, and weakness or sensory changes in the hand, particularly affecting intrinsic hand muscles PubMed Central.


Anatomy of the C7–T1 Intervertebral Disc

Structure and Location

The C7–T1 intervertebral disc lies between the seventh cervical (C7) and first thoracic (T1) vertebral bodies at the cervicothoracic junction. It consists of two main components: the gelatinous nucleus pulposus centrally and the concentric fibrocartilaginous annulus fibrosus peripherally. This disc provides flexibility between the rigid cervical spine and the more stable thoracic spine, accommodating unique transitional biomechanics KenhubPhysio-pedia.

Origin and Insertion

Embryologically, the intervertebral disc arises from the sclerotomal cells of the mesenchyme, with the nucleus pulposus derived from notochordal remnants and the annulus fibrosus from surrounding mesenchymal cells. The annulus fibers insert firmly into the vertebral endplates—each concentric lamella of the annulus attaches to the bony endplate of the adjacent vertebral bodies, anchoring the disc in place and transmitting axial loads through the spine NCBIWheeless’ Textbook of Orthopaedics.

Blood Supply

Intervertebral discs are largely avascular in adulthood. During early development, small vessels penetrate the outer annulus and endplates, but these regress postnatally. In adults, the disc relies on diffusion of nutrients (oxygen, glucose) from capillaries terminating at the endplates and outer annulus fibrosus. This limited vascularity contributes to poor intrinsic healing capacity of disc tissue KenhubDeuk Spine.

Nerve Supply

Sensory innervation of the C7–T1 disc originates from the sinuvertebral (recurrent meningeal) nerves, branches of the spinal nerve at each level. These nerves penetrate the outer one-third of the annulus fibrosus and posterior longitudinal ligament, mediating pain signals in cases of annular tears or endplate insult. No nociceptive fibers extend into the nucleus pulposus OrthobulletsNCBI.

Functions

  1. Load Bearing: Distributes axial loads evenly between vertebrae, protecting vertebral bodies from stress fractures.

  2. Shock Absorption: The nucleus pulposus acts like a hydraulic cushion, absorbing compressive forces during movement.

  3. Facilitating Motion: Allows flexion, extension, lateral bending, and rotation of the neck while maintaining spinal alignment.

  4. Spinal Stability: Annulus fibrosus fibers resist excessive motion, preserving vertebral integrity.

  5. Height Maintenance: Disc height establishes intervertebral foramen size, preventing nerve root compression.

  6. Nutrient Diffusion: Endplates permit bidirectional diffusion of nutrients and metabolites to maintain disc cell viability Physio-pediaDeuk Spine.
