Cervical Transligamentous Disc Compression Collapse is a condition in which the soft cushion between the bones of the neck (the intervertebral disc) pushes through its fibrous outer ring and tears the posterior longitudinal ligament, collapsing the disc space and pressing on the spinal cord or nerve roots. This “transligamentous” herniation is more severe than a simple bulge because the disc material escapes beyond both the annulus fibrosus and the ligament that normally contains it, leading to significant narrowing of the spinal canal or foramina and potential neurological deficits WikipediaNCBI. Left untreated, it can cause chronic neck pain, arm weakness, sensory loss, and even spinal instability or collapse of disc height over time kamranaghayev.com.
Anatomy
Structure & Location
The cervical spine consists of seven vertebrae (C1–C7) stacked between the skull and the thoracic spine. Between each pair of vertebral bodies lies an intervertebral disc made of a soft inner core (nucleus pulposus) and a tough outer ring (annulus fibrosus). Posterior to the vertebral bodies and discs runs the posterior longitudinal ligament (PLL), which helps contain the disc material within the spinal canal WikipediaPhysiopedia.
Origin & Insertion
Posterior Longitudinal Ligament (PLL): Originates at the body of the axis (C2) and extends down to attach to the posterior aspects of vertebral bodies and intervertebral discs as low as the sacrum. Superiorly, it continues as the tectorial membrane toward the skull base KenhubNCBI.
Blood Supply
Vertebral and Radicular Arteries: The spinal cord and surrounding ligaments receive blood from the anterior spinal artery (branching from vertebral arteries) and paired posterior spinal arteries, supplemented by segmental (radicular) arteries at each vertebral level. These vessels also send small branches to the intervertebral discs and the PLL NCBITeachMeAnatomy.
Nerve Supply
Sinuvertebral (Recurrent Meningeal) Nerve: A branch of each spinal nerve re-enters the spinal canal to innervate the PLL and the outer annulus fibrosus. This nerve carries pain signals when the disc or ligament is irritated or torn PMCTeachMeAnatomy.
Functions
Shock Absorption: Discs cushion axial loads.
Flexibility & Movement: Allow the neck to bend, rotate, and extend.
Stability: Ligaments (PLL) and discs hold vertebrae in alignment.
Load Distribution: Distribute weight evenly across vertebral bodies.
Spinal Cord Protection: Maintain space to prevent cord compression.
Height Maintenance: Keep vertebral spacing for foraminal patency PhysiopediaKenhub.
Types of Transligamentous Disc Herniation
Disc herniations are classified by how far the nucleus pulposus breaks through the annulus and ligaments:
Protrusion: Inner core presses against the annulus without tearing it.
Extrusion: Core material breaks through the annulus but remains connected.
Sequestration: Fragment separates entirely from the parent disc.
Transligamentous Extrusion: Disc material passes through the posterior longitudinal ligament into the spinal canal, often causing more severe compression RadiopaediaRadiopaedia.
Causes
Age-related disc degeneration

Frequently Asked Questions
What exactly is a transligamentous disc herniation?
It’s when the inner jelly-like core of the disc breaks through both its fibrous ring and the posterior ligament, entering the spinal canal and causing more severe compression than a simple herniation Wikipedia.How common is this condition?
Cervical disc herniation affects about 8% of all herniated discs, but the transligamentous subtype is less frequent and often follows trauma or severe degeneration Wikipedia.What makes it different from a regular herniated disc?
In a regular herniation, the disc bulges but stays contained by the ligament; in transligamentous cases, the ligament is torn, allowing disc material to move freely in the canal Radiopaedia.What risk factors should I watch for?
Key risks include age, smoking, heavy physical work, poor posture, and prior neck injury Wikipedia.Can it heal without surgery?
Mild cases may improve with conservative care, but severe transligamentous collapses often require surgical decompression to prevent permanent nerve damage Wikipedia.Which imaging test is best?
MRI is the gold standard because it shows soft tissues (disc, ligament, spinal cord) in detail Wikipedia.What exercises can help?
Gentle neck stretches, isometric strengthening, and postural exercises prescribed by a physical therapist are most effective Wikipedia.Is disc collapse the same as disc height loss?
Yes, collapse refers to a loss of disc height due to severe degeneration or extrusion of disc material Wikipedia.What is the long-term outlook?
With timely treatment, many patients regain function, but chronic changes like arthritis may persist Wikipedia.When is surgery recommended?
If you have progressive weakness, myelopathy signs, or intractable pain despite 6–12 weeks of conservative care Wikipedia.What are possible surgical complications?
Risks include infection, nerve injury, nonunion after fusion, and adjacent segment disease Wikipedia.Can this condition cause paralysis?
In extreme cases with untreated spinal cord compression, yes, it can lead to paralysis Wikipedia.How long is recovery after surgery?
Most patients need 6–12 weeks for soft-tissue healing, with full fusion requiring up to 6 months Wikipedia.Can it recur after treatment?
Recurrence rates vary; maintaining neck strength and good posture lowers the risk Wikipedia.How do I prevent future episodes?
Continue ergonomic practices, regular exercise, weight control, and avoid tobacco use Wikipedia.
