L4–L5 disc vertical herniation refers to the displacement of intervertebral disc material in a cranio-caudal (vertical) direction through a defect in the vertebral endplate at the level between the fourth and fifth lumbar vertebrae. Unlike typical posterior or lateral herniations, vertical herniation (often manifesting as a Schmorl’s node) involves disc tissue breaching the bony endplate and protruding into the vertebral body itself. This condition can be asymptomatic or provoke localized inflammatory pain, and in some cases may contribute to segmental instability or adjacent nerve irritation American Academy of Orthopaedic Surgeons.
A vertical disc herniation at L4–L5—also called an intravertebral herniation or Schmorl’s node—occurs when the soft inner gel of the L4–L5 intervertebral disc pushes upward or downward through a defect in the vertebral endplate, bulging into the adjacent vertebral body. Unlike common lateral herniations that press on nerve roots, this vertical protrusion primarily affects the bone-disc interface and may be discovered incidentally on MRI. While most Schmorl’s nodes cause no symptoms, when they do, inflammation and microfractures in the vertebra can lead to localized low back pain, particularly under axial loading (standing, lifting) OsmosisActive Sports Therapy.
Anatomy and Pathophysiology
The intervertebral disc at L4–L5 comprises a gelatinous nucleus pulposus surrounded by the annulus fibrosus, with superior and inferior cartilaginous endplates anchoring it to the vertebral bodies. In vertical herniation, an area of endplate weakness—due to degeneration, microfracture, or congenital defect—permits the nucleus pulposus to herniate upward or downward into the vertebral body (intravertebral herniation). The displaced disc tissue may elicit a local inflammatory response, leading to pain and marrow changes visible on MRI RadiopaediaAmerican Academy of Orthopaedic Surgeons.
Intravertebral herniations at the L4–L5 level are less common than posterior or lateral herniations, with Schmorl’s nodes detected incidentally in up to 20% of lumbar spine MRIs. Prevalence peaks in middle age (30–50 years) and shows no strong sex predilection, although heavy occupational loading and genetic factors can increase risk PMCRadiopaedia.
Types of Vertical Herniation
-
Intravertebral Herniation (Schmorl’s Node)
A true breach of the endplate allows disc material to protrude into the vertebral body, commonly asymptomatic but occasionally painful due to marrow edema and endplate microfractures Radiopaedia. -
Cranial Migration
Disc fragments travel superiorly from the disc space, lodging in the anterior epidural space above L4–L5. Cranial migration can compress traversing nerve roots and provoke radiculopathy PMC. -
Caudal Migration
Disc fragments migrate inferiorly toward the L5–S1 level, potentially indenting the thecal sac or exiting L5 nerve root. Caudal migration has been noted in up to 50% of sequestrated herniations PMC. -
Low-Grade Vertical Migration
Migration less than the posterior disc margin height (<100% of disc height) and without pedicle involvement; typically amenable to conservative management openorthopaedicsjournal.com. -
High-Grade Vertical Migration
Disc material extends beyond the posterior disc margin height but remains above the pedicle margin; may require percutaneous fragment removal under endoscopy openorthopaedicsjournal.com. -
Very High-Grade Vertical Migration
Migration beyond the inferior or superior pedicle margin, often necessitating open or endoscopic decompression due to challenging fragment access openorthopaedicsjournal.com. -
Contained vs. Uncontained Vertical Herniation
Contained vertical herniation retains an intact outer annulus covering, whereas uncontained types have free disc fragments within the vertebral body or epidural space American Academy of Orthopaedic Surgeons.
Causes
-
Degenerative Disc Disease: Age-related loss of disc water content and elasticity weakens endplates, promoting vertical breach.
-
Acute Trauma: Sudden axial loading—such as a fall from height—can fracture endplates, allowing disc material intrusion.
-
Repetitive Microtrauma: Chronic bending and lifting stresses produce microfractures in the endplate over time.
-
Heavy Occupational Loading: Jobs involving manual labor accelerate endplate wear and fatigue, predisposing to herniation.
-
Genetic Predisposition: Family history of Schmorl’s nodes or disc degeneration confers higher susceptibility.
-
Poor Posture: Sustained flexion or extension postures create asymmetric loading on endplates.
-
Obesity: Excess axial load from body weight increases intradiscal pressure and endplate strain.
-
Smoking: Nicotine impairs disc nutrition and endplate healing, fostering fissure formation.
-
Nutritional Deficiency: Inadequate intake of collagen-synthesizing nutrients (vitamin C, protein) undermines endplate integrity.
-
Congenital Endplate Defects: Developmental irregularities in endplate ossification create inherent weakness.
-
Bone Density Loss (Osteoporosis): Reduced vertebral strength facilitates endplate cracking.
-
Vibration Exposure: Long-term whole-body vibration (e.g., heavy machinery operators) stresses discs vertically.
-
Sedentary Lifestyle: Poor core muscle support increases shear forces on the lumbar spine.
-
Inflammatory Conditions: Spondyloarthropathies cause adjacent disc and endplate inflammation, weakening structure.
-
Prior Spine Surgery: Altered biomechanics and scar formation around L4–L5 predispose to endplate failure.
-
Neoplastic Infiltration: Vertebral body metastases or primary tumors erode endplates, permitting disc intrusion.
-
Discitis (Infection): Bacterial infection of the disc and endplate (pyogenic or tubercular) can create defects.
-
Metabolic Disorders (Diabetes): Microvascular disease compromises disc nutrition and endplate repair.
-
Excessive Sports Activity: High-impact sports (gymnastics, weightlifting) accelerate endplate fatigue.
-
Iatrogenic Injury: Vertebral augmentation procedures (e.g., vertebroplasty) may inadvertently fracture endplates.
