Lumbar disc intradural displacement—also called intradural disc herniation—is a rare, severe form of lumbar disc pathology in which the nucleus pulposus tears through both the annulus fibrosus and the dura mater, entering the intradural (subarachnoid) space. Unlike more common extradural herniations, intradural displacement may directly compress spinal nerve roots within the thecal sac or, in extreme cases, the cauda equina. Patients often present with acute, severe radicular pain, neurological deficits (e.g., motor weakness, sensory loss), and in some, signs of cauda equina syndrome such as bladder or bowel dysfunction. Because of its rarity—accounting for less than 0.3 % of all disc herniations—high clinical suspicion, coupled with advanced imaging (MRI with contrast, CT myelography), is required for diagnosis. Early recognition and prompt management are critical to prevent permanent neurological injury.
Intradural lumbar disc displacement occurs when nucleus pulposus material breaches the annulus fibrosus and penetrates the dura mater, lodging within the thecal sac around the spinal cord or nerve roots. This rare form of disc herniation accounts for approximately 0.04 %–0.33 % of all lumbar herniations and most frequently involves the L4–L5 and L3–L4 levels PubMed. Clinically, it often presents more acutely and with more severe neurological deficits than standard extradural herniations.

Clinically, it often presents more acutely and with more severe neurological deficits than standard extradural herniations.
Types of Intradural Lumbar Disc Displacement
Type A (Dural Sac Herniation). In Type A herniations, disc material traverses the ventral dura and lies freely within the dural sac, often adjacent to cauda equina nerve roots. This “intrathecal” intrusion may compress multiple roots simultaneously and is the subtype most commonly reported in the literature PMC.
Type B (Intraradicular Herniation). Type B herniations involve disc fragments that migrate into the dural sleeve surrounding a single nerve root (the preganglionic region), but do not enter the main dural sac. Because the fragment is confined to the root sleeve, symptoms can mimic root tumors or meningeal cysts PMC.
Causes of Lumbar Intradural Disc Displacement
Each paragraph below names one “cause” in bold and then explains it in plain English. Citations at the end of each paragraph support the evidence.
-
Genetic Predisposition. A strong hereditary component underlies disc degeneration, with family studies showing that up to 75 % of susceptibility to lumbar disc pathology is genetic. Variants in matrix‐remodeling genes appear to drive disc weakening long before clinical symptoms arise PMC.
-
Vitamin D Receptor (VDR) Gene Polymorphism. Polymorphisms in the VDR gene (e.g., Taq I and Fok I) alter glycosaminoglycan synthesis in the nucleus pulposus, destabilizing disc structure and increasing the likelihood of annular tears that can progress intradurally PMC.
-
Collagen Type I Gene Variants. Mutations in COL1A1 are linked to reduced tensile strength in both the annulus fibrosus and vertebral endplates, facilitating tear formation through which disc material may herniate into the dura PMC.
-
Collagen Type IX Gene Variants. Collagen IX mutations compromise the disc’s extracellular matrix integrity; animal and human studies show that these changes correspond to higher rates of disc protrusion and potential intradural migration PMC.
-
Aggrecan Gene VNTR Polymorphism. Variable‐number tandem repeats in the ACAN gene affect proteoglycan content in the nucleus pulposus, diminishing its shock-absorbing capacity and predisposing to fissuring and dural perforation PMC.
-
Matrix Metalloproteinase (MMP) Overexpression. Elevated MMP-3 levels accelerate breakdown of annular collagen, creating microscopic defects that may expand under mechanical stress to allow intradural disc migration PMC.
-
Age-Related Disc Degeneration. Cellular senescence leads to reduced proteoglycan synthesis and hydration of the nucleus pulposus; over decades, this process thins the annulus fibrosus and increases the risk of tears extending through the dura PMC.
-
Obesity and Excess Body Weight. Chronic axial overload from high body mass index alters load distribution across lumbar discs, accelerating annular fissuring and weakening the ventral dura barrier PMC.
-
Smoking and Nicotine Exposure. Tobacco toxins impair disc cell nutrition and promote microvascular occlusion in the vertebral endplates, hastening degeneration and potential intradural breach PMC.
-
Diabetes Mellitus. Chronic hyperglycemia induces glycation end products in disc collagen, reducing mechanical resilience and increasing susceptibility to intradural herniation under minor stress PMC.

Frequently Asked Questions
-
What exactly is intradural disc displacement?
Intradural displacement occurs when disc material tears through the outer annulus and dura, entering the intradural space and compressing nerve roots directly. -
How rare is this condition?
It accounts for less than 0.3 % of all lumbar disc herniations, making it an uncommon but serious diagnosis. -
What are the typical symptoms?
Sudden severe back pain, shooting leg pain, motor weakness, sensory loss, and in some cases bowel or bladder dysfunction. -
Which imaging test is best for diagnosis?
MRI with gadolinium contrast is ideal for visualizing intradural fragments; CT myelography can confirm CSF flow interruption. -
Can conservative therapy ever resolve intradural displacement?
Rarely; because the disc material is inside the dura, most cases ultimately require surgical removal. -
What is the recovery time after surgery?
Most patients regain baseline activity by 6–12 weeks postoperatively, though full neurological recovery may take several months. -
Are there risks of recurrence?
Recurrence is uncommon if surgical decompression and stabilization are adequate, but adjacent‐level disease can develop over years. -
Can I return to work after surgery?
Sedentary workers may return in 4–6 weeks; those with manual labor often require ≥3 months of rehabilitation. -
Is physical therapy safe post-surgery?
Yes—early guided PT focusing on gentle mobilization and core activation improves outcomes and reduces stiffness. -
Do supplements really help my discs?
Supplements like glucosamine, chondroitin, and omega-3s may support disc health but are adjuncts, not replacements for medical care. -
Will I need fusion after decompression?
Fusion is recommended if there’s instability, vertebral slippage, or when aggressive bone removal is necessary. -
What lifestyle changes reduce future risk?
Weight management, ergonomic work setups, quitting smoking, and regular core exercises help prevent recurrence. -
Can yoga worsen my condition?
Gentle, supervised yoga can improve flexibility and strength; avoid advanced poses that hyperextend or twist the spine during acute phases. -
Is stem cell therapy a proven treatment?
Early studies of MSC and PRP injections show promise for disc regeneration, but long-term efficacy and safety are under investigation. -
When should I consider a second opinion?
If you have persistent symptoms despite expert evaluation or if surgery recommendations are unclear, seeking another specialist can ensure optimal care.
