Cervical Intervertebral Disc Bulging

A cervical intervertebral disc bulge at the C7–T1 level occurs when the fibrous outer ring of the disc between the seventh cervical (C7) and first thoracic (T1) vertebrae weakens and extends outward. This bulging can press on nearby nerves, causing neck and arm symptoms. Understanding its anatomy, causes, symptoms, tests, treatments, and prevention helps patients and providers manage it effectively.

disc bulge represents displacement of the outer fibers of the annulus fibrosus beyond the margins of the adjacent vertebral bodies, involving more than one-quarter (25% or 90°) of the circumference of an intervertebral disc 3. Because it is limited by the annulus fibrosus it does not extend above or below the attached margins of the disc 3. Disc bulges, along with vertebral endplate bowing, are responsible for the disc height loss that is seen with aging.


Anatomy of the C7–T1 Intervertebral Disc

Structure

The C7–T1 disc is made of two main parts:

  • Annulus fibrosus: Several concentric layers of tough fibrocartilage (mostly type I collagen) that form the disc’s outer ring.

  • Nucleus pulposus: A gel-like center rich in water and proteoglycans that cushions the spine. Spine-healthWikipedia

Location

This disc sits at the cervicothoracic junction (CTJ), bridging the flexible neck (cervical spine) and the more rigid upper back (thoracic spine). Spine-health

Origin & Insertion

The annulus fibers are firmly anchored to the cartilaginous endplates of the adjacent vertebral bodies (C7 above, T1 below), securing the disc in place. Wikipedia

Blood Supply

In adults, the disc is largely avascular. Only the outer 10–30% of the annulus fibrosus receives tiny capillaries from branches of the vertebral endplate vessels. The nucleus gets nutrition by diffusion across the endplates. MedscapeWikipedia

Nerve Supply

  • Sinuvertebral (recurrent meningeal) nerves supply the outer annulus fibrosus and posterior longitudinal ligament.

  • Ventral rami & gray rami communicans supply the anterior annulus and longitudinal ligaments.

  • Posterior rami innervate the facet joints and paraspinal muscles. MedscapeMedscape

Functions

  1. Shock absorption: Cushions impacts during head and neck movement. Spine-health

  2. Load transmission: Passes weight from head/neck to upper back. Wikipedia

  3. Mobility: Enables flexion, extension, lateral bending, and rotation. Wikipedia

  4. Height maintenance: Preserves disc height and neural foramen size. Wikipedia

  5. Pivot point: Allows smooth joint movement between vertebrae. Wikipedia

  6. Pressure distribution: Spreads mechanical forces evenly across endplates. Wikipedia


Types of C7–T1 Disc Bulging

Discs at C7–T1 can bulge or herniate in different ways and directions:

  • Broad-based bulge: >25% of disc circumference extends beyond vertebral edges.

  • Focal bulge: ≤25% of circumference.

  • Protrusion: Disc material pushes out but base remains wider than bulge.

  • Extrusion: Bulging material’s width exceeds its base; annulus tears.

  • Sequestration: Fragment of nucleus completely separates.

  • By location (where bulge presses):

    • Central disc bulge(toward spinal cord) – A central disc bulge, also known as a disc prolapse, occurs when the nucleus pulposus (the soft, jelly-like center of the disc) protrudes outward, pushing against the annulus fibrosus (the tough outer layer of the disc) and potentially into the spinal canalThis bulge can compress nearby nerve roots or the spinal cord, leading to pain, numbness, weakness, or other symptoms

    • Paracentral disc bulge(toward exit nerve roots) – A paracentral disc bulge, also known as a paracentral disc protrusion or herniation, occurs when the disc material bulges out to the side of the spinal canal, but not directly in the centerThis bulge can occur either to the left or right side of the midline. It’s often caused by disc annulus fissures, which weaken the disc’s structural integrity. 

    • Central and both paracentral disc bulgeA central disc bulge, also known as a central disc herniation, occurs when the bulging disc material protrudes directly into the spinal canal. A paracentral disc bulge, also referred to as a subarticular or lateral recess herniation, bulges off to the side of the spine, either left or right, near the center. 
    • Parasagittal disc bulgeA “parasagittal disc bulge” refers to a type of bulging disc where the protrusion is located on the side of the spinal column, rather than directly in the centerThis means the disc material is bulging outwards and potentially pressing on nerves or the spinal canal. 
    • Posterior disc bulgeA posterior disc bulge, also known as a bulging disc, occurs when the disc at the back of the spine extends beyond its normal boundariesThis bulge can press on the spinal nerves and cause various symptoms like pain, numbness, and weakness, particularly in the lower limbs. 
    • Posterolateral – A “posterolateral bulge” refers to a bulging of the intervertebral disc outwards and towards the side (laterally) of the spine, specifically on the posterior (back) side.

    • Foraminal (in intervertebral foramen)A foraminal bulge, also known as foraminal disc protrusion or neural foraminal stenosis, occurs when a disc in the spine extends beyond its normal boundaries and presses on the nerve roots within the foraminal canal.

    • Proximal Extraforaminal – Disc material migrates just outside the foramen but close to the vertebral body.

    • Distal Extraforaminal – Herniation extends farther lateral, beneath the facet joint and muscle.

    • Migrated Herniation: An extruded or sequestered fragment moves either upward (superior) or downward (inferior) from its original level
    • Superiorly Migrated – Disc fragments move upward, potentially affecting the nerve root above.

    • Inferiorly Migrated – Fragments drop downward, possibly compressing the nerve root below.

    • Extraforaminal (beyond foramen) BioMed CentralMiami Neuroscience Center

    • Circumferential Bulge: Uniform outward displacement of the entire annulus.

    • Focal Bulge: Localized protrusion in one area.

    • Asymmetric Bulge: Predominantly on one side, often compressing a nerve root.

    • Lateral Recess Bulge: Affects the space where nerve roots travel before exiting.

    • Lateral Bulge: Towards the side, impacting nerve roots.

    • Posterolateral bulge: Bulge presses on nerve roots exiting between vertebrae.
    • Paramedian Bulge: Bulge that occurs just off the midline, often compressing one nerve root.

    • Contained Bulge: Annulus is intact but bulging.

    • Non-Contained Bulge: Outer annulus has tears, more risk of extrusion.

    • Diffuse bulge : A diffuse disc bulge, also known as a bulging disc, occurs when the outer layer of an intervertebral disc (annulus fibrosus) weakens or becomes damaged, causing the inner gel-like material (nucleus pulposus) to bulge out. This bulge can put pressure on surrounding spinal structures like nerves or the spinal cord, leading to pain, numbness, or weakness.

    • Degenerative Bulge – A “degenerative bulge,” also known as a bulging disc or disc prolapse, is a condition where the inner part of a spinal disc pushes against the outer layer, causing it to bulge outwardThis can occur due to the natural aging and degeneration of the spine, leading to the breakdown and weakening of the disc. 
    • Traumatic BulgeA “traumatic bulge” typically refers to a protrusion or swelling caused by injury or traumaIt can occur in various areas of the body, including the spine, abdomen, or even the eye. 
    • Intradural disc bulging – Intradural disc bulging, also known as intradural disc herniation (IDH), occurs when the soft, jelly-like center of a herniated disc pushes into the dural sac, the protective sheath around the spinal cord and nerve rootsThis is a rare condition, with a very small percentage of all disc herniations being intradural. 
    • Extradural disc bulge – An extradural disc bulge, also known as a posterior extradural disc herniation, occurs when the disc’s outer layer (annulus fibrosus) weakens and the inner gel-like material (nucleus pulposus) pushes outwards, potentially causing nerve or spinal cord compressionThis bulging can lead to pain, numbness, or weakness, depending on the affected nerve or spinal cord level.
    • Annular Disc BulgeThe condition occurs when the outer layer of an intervertebral disc starts to weaken, leading to a bulging disc. An annular bulge happens when the outer part of the disc, called the annulus fibrosus, begins to bulge outward. This occurs without the inner portion of the disc, known as the nucleus pulposus, breaking through the outer layer. The disc remains intact, but the pressure it exerts on surrounding structures can lead to pain and discomfort.
    • Subarticular Disc Bulge Because the PLL is not as thick in this region, this is the number one region for disc herniations.
    • Subligamentous Disc – A “subligamentous disc ” describes a herniated disc where the herniated material is contained by the posterior longitudinal ligament (PLL)In other words, the disc’s nucleus pulposus has ruptured through the outer layers of the annulus fibrosus, but the ruptured material hasn’t penetrated the PLL. 
    • Free fragment discA “free fragment disc,” also known as a sequestered disc, is a type of herniated disc where a piece of the disc material breaks off and separates from the main disc structureThis detached fragment can then move around and potentially compress nerves or the spinal cord, causing pain, weakness, or numbness
    • Transligamentous DiscA transligamentous disc herniation occurs when the herniated disc material extends through the outer fibers of the annulus and the posterior longitudinal ligament (PLL), but remains connected to the disc spaceThis means the disc material has breached the outer layers of the disc but is not yet fully separated or “sequestrated” into the spinal canal. 
    • Extraligamentous bulge – An “extraligamentous bulge” refers to a type of disc herniation where the herniated disc material extends beyond the posterior longitudinal ligament (PLL). This means the disc material is located behind the PLL, in the epidural space, due to a tear in the PLL. In contrast, a “subligamentous” herniation would have the herniated disc material still covered by the intact PLL. 
    • Thecal sac indentationIndentation of the thecal sac, which surrounds the spinal cord and nerve roots, can occur due to various factors, including disc bulges, spinal stenosis, and other structural issuesThis indentation can compress the spinal cord and nerve roots, leading to a range of symptoms like pain, numbness, and weakness. 
    • Annular tears  – An annular tear is a crack or fissure in the annulus fibrosus, the outer layer of a spinal discThese tears can develop due to various factors, including aging, injury, or repetitive strain. While many annular tears are asymptomatic, some can cause pain, and in severe cases, the inner core of the disc (nucleus pulposus) may bulge or herniate through the tear. 
    • Annulus fibrosusThe annulus fibrosus is the tough outer ring of an intervertebral disc in the spine, surrounding the softer nucleus pulposusIt’s composed of concentric layers of fibrocartilage and fibrous tissue, designed to withstand compressive and tensile forces. 
    • Transverse nerve root compressionTransverse nerve root compression, also known as nerve root impingement or radiculopathy, refers to the condition where a spinal nerve root is compressed or irritated, often due to a herniated disc, bone spurs, or other factorsThis can lead to pain, numbness, and weakness in the areas supplied by the affected nerve. 
    • Terminal spinal cord compressionTerminal spinal cord compression, often caused by the spread of cancer to the spine, is a serious condition that can lead to paralysis and other neurological deficits if not treated promptlyThis condition occurs when a tumor or other mass compresses the spinal cord, disrupting its function and causing symptoms like pain, weakness, and numbness. 
    • Compression collapse of cervical vertebraA compression collapse, specifically in the context of the spine, refers to a vertebral compression fracture where a vertebra in the spine collapses or becomes compressedThis can be caused by various factors, including osteoporosis, injury, or underlying medical conditions. 
    • Bilateral neural foraminal narrowingBilateral neural foraminal narrowing refers to a condition where the openings in the spine through which nerve roots exit, called foramina, narrow on both sides of the vertebral columnThis narrowing can compress the nerve roots, leading to symptoms such as pain, numbness, tingling, or weakness in the limbs. 
    • Forward slip/anterolisthesis of  lumber vertebrae – A forward slip of L5 over the lower lumbar vertebrae, specifically the sacrum (L5-S1), is a condition called spondylolisthesisThis occurs when the L5 vertebra shifts forward on top of the S1 vertebra, causing a misalignment in the lower spine. 
    • Backword slip/Retrolisthesis of lumber vertebraeA backward slip of lumbar vertebrae, also known as lumbar retrolisthesis, occurs when one or more vertebrae in the lower spine shift backward on the vertebrae below themThis slippage can put pressure on nerves, causing pain, numbness, tingling, or weakness in the legs and back. 
    • Anterior wedging of lumbar vertebraeAnterior wedging of lumbar vertebrae refers to a condition where the front (anterior) portion of a lumbar vertebra is compressed or flattened, causing it to appear wedge-shaped when viewed on an X-ray or other imagingThis wedging can occur due to various reasons, including fractures, osteoporosis, or other conditions that weaken the bone. 
    • Posterior wedging of vertebrae – Posterior wedging of vertebrae refers to a condition where the posterior (back) height of the vertebral body is greater than the anterior (front) height, creating a wedge-shaped appearanceThis can be a normal physiological feature, particularly in the lower lumbar spine (L4-L5), or it can be a sign of other conditions like vertebral fractures or scoliosis. 
    • Hyper intense of vertebrae – Hyperintense vertebral lesions, often visible on MRI, are common in degenerative spine disease, particularly in the vertebral bodies and endplates, and can be associated with other degenerative changes like disc degeneration and osteophytes. These lesions are often seen in Modic type 1 and 2 changes. They can also be found in other areas of the spine, such as facet joints and in cases of degenerative spondylolisthesis or spinal stenosis. The appearance of these lesions on MRI, especially on T2-weighted and fat-suppressed T2 images, helps in their diagnosis and differentiation from other conditions like infections or tumors.
    • Hypo intense of vertebrae – Hypointense vertebrae on MRI, especially on T1-weighted images, can indicate various conditions, including but not limited to, vertebral fractures, bone marrow edema, or certain types of tumorsThese findings are often compared to the signal intensity of adjacent tissues like skeletal muscle or intervertebral discs.
    • Retropulsion vertebraeRetropulsion in the context of vertebral fractures refers to the posterior displacement of a bone fragment from the vertebral body into the spinal canal, potentially causing compression of the spinal cord or nerve rootsThis can lead to spinal cord injury, stenosis (narrowing of the spinal canal), or nerve root compression.
    • Internal Disc Disruption – Internal disc disruption (IDD) is a condition where the intervertebral disc in the spine is damaged internally, causing pain, particularly in the lower back. It’s characterized by annular fissures (tears in the outer ring of the disc) and a distortion of the disc’s internal structure, without a full herniation (a complete rupture). While the disc may appear intact externally, the internal damage can irritate the nerves and surrounding tissues, leading to pain. Internal disc disruption is a distortion of the nucleus pulposus, with annular fissures, without developing disc herniation. 
    • Disc displacement – Disc displacement develops when a disc in the spinal column shifts from its original position and presses against the spinal nerves. This causes neck and back pain, numbness, and muscle weakness.
    • Disc Derangement – Lumbar Disc Derangement (otherwise known as discogenic pain) is a condition of the low back where the disc becomes painful. Lumbar Disc Derangement is thought to be caused by multiple small tears that develop in the disc; nuclear material seeps out into these tears and irritates the nerve endings in the outer portion of the disc.
    • Cartilaginous endplates – Cartilaginous endplates (CEPs) are thin layers of hyaline cartilage found at the top and bottom of intervertebral discs, acting as a barrier and a pathway for nutrient transport. They are crucial for the disc’s nutrition and stability, and their health is important for preventing disc degeneration and related pain. 
    • Uncovertebral – Uncovertebral joint disease, also known as Luschka’s joints or uncovertebral joint hypertrophy, refers to a condition where the uncovertebral joints in the neck become enlarged and degenerate, often due to aging and wear and tearThis can lead to pain, stiffness, and limited neck movement, and potentially compress nerves. 
    • Disc Calcification – Disc Calcification of the intervertebral disc, also known as calcific discitis or calcific discopathy, is a condition where calcium deposits form within the disc space, potentially leading to pain, limited movement, and, in rare cases, nerve root or spinal cord compression. 
    • Discitis – Discitis is an infection of the intervertebral discs in the spine, often caused by bacteriaIt leads to inflammation and can cause severe back pain, fever, and potentially neurological problems. Treatment typically involves antibiotics and pain management, and in some cases, surgery may be necessary. 
    • Vertical herniation – Vertical herniation, also known as intravertebral or Schmorl’s node herniation, occurs when the disc material of the spinal disc protrudes into the vertebral body, rather than laterally or posteriorlyThis happens when the disc material is pushed through the endplate of the vertebra into the bone itself. 
    • Disc Dehydration – Disc Dehydration can affect the nucleus pulposus, the gel-like center of spinal discs, leading to loss of hydration and potential issues like back pain and disc degenerationThis occurs because the nucleus pulposus, which is rich in water, loses its moisture when dehydrated, causing it to shrink and potentially leading to damage. 
    • Disc desiccation – Disc desiccation, also known as disc dehydration, is a natural aging process where the intervertebral discs in the spine lose their water content, leading to a decrease in flexibility and potentially causing painIt’s a common component of degenerative disc disease, where the discs gradually break down. Disc desiccation is the gradual loss of hydration (water) of an intervertebral disc in the spine, which leads to disc dehydration and disc degeneration.
