Cervical Disc Transligamentous Sequestration

A transligamentous sequestration occurs when the nucleus pulposus of an intervertebral disc extrudes with complete disruption of the annular fibers and the posterior longitudinal ligament?, resulting in a free fragment (sequestrum) within the spinal canal that is no longer connected to the parent disc.

Anatomy of the Cervical? Intervertebral Disc

Structure

• Nucleus Pulposus: Gel-like core rich in water and proteoglycans, acting as the main shock absorber.

• Annulus Fibrosus: Concentric lamellae of collagen fibers providing tensile strength and containment of the nucleus.

• Vertebral Endplates: Thin hyaline cartilage? layers that separate the disc from adjacent vertebral bodies and facilitate nutrient exchange. Wikipedia

Location

• Interposed between adjacent cervical? vertebrae from C2–C3 through C7–T1, these discs account for 6 of the 23 total spinal discs. Wikipedia

Attachment (“Origin” & “Insertion”)

• The annulus fibrosus attaches peripherally to the ring apophysis of the vertebral bodies and centrally to the cartilaginous endplates, anchoring the disc within the intervertebral space. Wikipedia

Blood Supply

• In early life, small vessels penetrate the outer annulus and endplates but regress postnatally. In adulthood, discs are largely avascular; nutrients diffuse via the endplates through osmosis. KenhubNCBI

Nerve Supply

• The sinuvertebral (recurrent meningeal) nerve, formed from a somatic root of the ventral ramus and a sympathetic contribution from the gray ramus communicans, re-enters the canal via the intervertebral foramen to innervate the outer annulus fibrosus and posterior longitudinal ligament?, mediating pain? sensations. RadiopaediaPMC

Functions

1. Shock Absorption: Distributes compressive loads evenly.

2. Flexibility: Allows slight movement between vertebrae (flexion, extension, lateral bending, rotation).

3. Load Transmission: Transfers mechanical forces through the spine.

4. Spinal Stability: Maintains alignment of vertebral bodies.

5. Height Maintenance: Contributes to overall spinal column length (~25%).

6. Ligamentous Role: Acts as a fibrous joint (symphysis) to hold vertebrae together. Wikipedia

Types of Disc Herniation

Intervertebral disc herniations are categorized based on displacement and continuity with the parent disc:

• Protrusion: Disc bulge without full-thickness annular tear.

• Extrusion: Nucleus material breaches the annulus but remains contained by the posterior longitudinal ligament?.

• Sequestration (Extrusion with Fragment Loss): Free fragment separated from the disc; subdivided into:

  • Subligamentous Sequestration: Fragment splays beneath the posterior longitudinal ligament?.

  • Transligamentous Sequestration: Fragment disrupts and passes through the posterior longitudinal ligament? into the canal. Verywell HealthSpringerOpen

1. Free fragment sequestration: Disc pieces break free from the main disc and float within the canal.
2. Intradural sequestration: Rarely, fragments penetrate the dura mater and enter the dural sac.

Causes

• Poor posture. Holding the head and shoulders forward for long periods places extra pressure on cervical? discs, causing wear.
• Aging. Discs naturally lose water and elasticity with age, making them more prone to tearing and herniation.
• Heavy lifting. Lifting heavy objects incorrectly can increase intradiscal pressure and tear the disc.
• Sudden trauma. Falls or accidents can abruptly tendon?. সহজ বাংলা: মাংসপেশি/টেনডনে টান।" data-rx-term="strain" data-rx-definition="A strain is injury to a muscle or tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।">strain? the neck, leading to disc rupture.
