Posterior Lumbar Disc Displacement at L4–L5

Lumbar disc posterior displacement at the L4–L5 level refers to the backward movement of intervertebral disc material beyond its normal boundaries at the fourth and fifth lumbar vertebrae. This displacement can impinge on neural structures—most commonly the L5 nerve root—leading to a spectrum of clinical manifestations ranging from localized back pain to radiculopathy (nerve root irritation) and, in severe cases, cauda equina syndrome. The term “posterior displacement” encompasses both contained and uncontained herniations, distinguished by whether the disc material remains covered by the outer annulus fibrosus and/or the posterior longitudinal ligament. Given the high load-bearing function and mobility required at L4–L5, this level is particularly susceptible to degenerative changes and mechanical stress, making posterior displacement here one of the most frequent sources of lumbar disc pathology Orthobullets.

Posterior displacement—often called a posterior disc herniation or protrusion—occurs when the soft center (nucleus pulposus) of the disc between the fourth and fifth lumbar vertebrae pushes backward against the tough outer ring (annulus fibrosus). This can irritate nearby nerve roots, causing back pain and leg symptoms. Unlike common posterolateral herniations, a purely posterior displacement risks compressing the cauda equina (the bundle of nerves at the bottom of the spinal canal), making prompt recognition important Mayo Clinic.

Types of Posterior Displacement

Morphological Types

Disc Bulge
A disc bulge occurs when disc tissue extends beyond the ring apophyses around the entire circumference of the vertebral body, involving more than 25% of the disc perimeter. Although bulges are broad and typically asymptomatic, they represent the initial stage of degenerative disc disease and can progress to herniation Radiology Assistant.

Disc Protrusion
In a protrusion, there is a focal displacement of disc material where the greatest distance between the edges of the herniated material is less than the width of its base at the disc space. Protrusions are contained by intact annulus fibers and/or posterior longitudinal ligament Radiology Assistant.

Contained Extrusion
Contained extrusions occur when the displaced nucleus pulposus material breaches the annulus fibrosus but remains under the cover of the posterior longitudinal ligament. The herniated fragment’s width exceeds its base, yet continuity with the parent disc is preserved Surgery Reference.

Uncontained Extrusion
An uncontained extrusion, often simply called an extrusion, involves disc material that not only breaches the annulus but also escapes beyond the posterior longitudinal ligament, losing some continuity with the parent disc Radiology Assistant.

Sequestration
Sequestration—or free fragment—is a subtype of extrusion in which the herniated disc material completely separates from the intervertebral disc and can migrate within the spinal canal Radiopaedia.

Location-Based Types

Central Posterior Displacement
Central herniations occur directly behind the disc space, often compressing the thecal sac and, in large herniations, multiple nerve roots (cauda equina) Radiology Assistant.

Paracentral/Subarticular Displacement
Paracentral herniations are the most common, occurring just lateral to the midline, where the posterior longitudinal ligament is thinner. These typically impinge on the traversing nerve root—in L4–L5 herniations, the L5 root Orthobullets.

Foraminal Displacement
Foraminal (or far lateral) herniations extend into the intervertebral foramen, compressing the exiting nerve root at the same level—at L4–L5, this would be the L4 root. Although less common (5–10%), they often cause severe radicular pain due to dorsal root ganglion involvement Radiology Assistant.

Extraforaminal Displacement
Also known as extraforaminal or “far lateral” herniations, these occur lateral to the foramen and are rare, typically affecting the exiting nerve root and presenting diagnostic challenges Surgery Reference.

Causes of Posterior Displacement at L4–L5

1. Age-Related Disc Degeneration
   Disc degeneration due to aging leads to dehydration of the nucleus pulposus and weakening of the annulus fibrosus, making herniation more likely with minor stress Mayo Clinic.

2. Genetic Predisposition
   Polymorphisms in genes encoding collagen (types I and IX), aggrecan, and matrix metalloproteinases (e.g., MMP3) are implicated in accelerated disc degeneration and herniation risk Wikipedia.

3. Repetitive Mechanical Overload
   Jobs requiring heavy lifting, bending, or twisting impose repetitive compressive forces on L4–L5, promoting annular fissures and posterior displacement Mayo Clinic.

4. Prolonged Sitting (Sedentary Lifestyle)
   Sustained compression loads during extended sitting lead to disc nutrition impairment and mechanical fatigue, increasing herniation risk Spine-health.

5. Obesity
   Elevated body mass index (BMI) increases axial load on the lumbar spine, correlating strongly with disc herniation and spinal stenosis, particularly at upper lumbar levels PubMedMDPI.

6. Smoking
   Nicotine reduces oxygen delivery to disc tissue, accelerating degenerative changes and increasing susceptibility to rupture Mayo Clinic.

7. Traumatic Injury
   Acute trauma—such as falls or motor vehicle collisions—can cause annular tears and abrupt disc extrusion at L4–L5 Mayo Clinic.

8. Vibration Exposure
   Chronic vibration from heavy machinery or vehicle driving contributes to microtrauma and disc degeneration over time MDPI.

9. Poor Posture
   Persistent lumbar hyperflexion or hyperextension distorts normal load distribution, stressing the posterior annulus and promoting herniation Mayo Clinic.

10. Heavy Weightlifting Without Proper Technique
    Lifting with the back instead of the legs concentrates stress on the disc, risking annular rupture Mayo Clinic.

11. Prolonged Standing
    Extended periods of standing impose continuous compressive forces, especially when combined with poor ergonomics Spine-health.

12. Core Muscle Weakness
    Insufficient trunk muscle support fails to stabilize the spine, allowing excessive disc movement and annular strain Johns Hopkins Medicine.

13. Diabetes Mellitus
    Microvascular compromise in diabetes may impair disc nutrition and accelerate degeneration Wikipedia.

14. Infection (Discitis)
    Disc space infection can weaken the annulus fibrosus, predisposing to herniation Johns Hopkins Medicine.

15. Connective Tissue Disorders
    Conditions like Marfan syndrome or Ehlers–Danlos syndrome weaken annular collagen, increasing risk of rupture Wikipedia.

16. Lumbar Instability
    Segmental hypermobility due to facet joint degeneration or spondylolisthesis increases shear forces on the disc Orthobullets.

17. Inflammation and Cytokine Release
    Local inflammatory mediators (TNF-α, IL-6) degrade matrix proteins and sensitize nerve roots, facilitating herniation under lower loads Orthobullets.

18. Recurrent Microtrauma
    Low-grade, repeated stresses—such as poor lifting mechanics—accumulate microtears in the annulus, leading to displacement MDPI.

19. Vertebral Endplate Changes (Modic Changes)
    Endplate degeneration (Modic type I–III) reflects disc pathology that often coexists with herniation Radiology Assistant.

20. Nutritional Deficiencies
    Inadequate intake of nutrients essential for collagen synthesis (e.g., vitamin C) may impair annular integrity over time Wikipedia.
