Lumbar Disc Backword Slip at L1 – L2

Lumbar retrolisthesis refers to the posterior (backward) displacement of one vertebral body relative to the one immediately below it. In the case of L1–L2 retrolisthesis, the first lumbar vertebra (L1) shifts posteriorly on the second lumbar vertebra (L2), disrupting the normal alignment of the spinal column. This displacement can reduce the anterior–posterior diameter of the spinal canal, exaggerate mechanical stress on the anterior longitudinal ligament, annulus fibrosus, cartilage end plates, and zygapophyseal joint capsules, and may lead to buckling of the posterior annulus, disc bulging, and nerve root compression WikipediaPMC. Functionally, L1–L2 retrolisthesis can impair load distribution, alter segmental motion, and create focal concentrations of shear forces, potentially contributing to pain, stiffness, and neurologic symptoms in the lower back and lower extremities WebMD.

The intervertebral disc between L1 and L2 consists of the nucleus pulposus— a gelatinous core responsible for axial loading and shock absorption— surrounded by the annulus fibrosus, a multilamellar fibrocartilaginous ring that provides tensile strength and containment of the nucleus Healthline. In retrolisthesis, posterior translation of L1 over L2 may stretch or tear annular fibers, accelerate disc degeneration, and provoke inflammatory cascades that sensitize nociceptors in the disc and adjacent soft tissues. Over time, chronic posterior slippage can foster osteophyte formation, marginal sclerosis, and facet joint arthropathy, further exacerbating mechanical instability and neural encroachment Wikipedia.

A lumbar disc backward slip—medically termed retrolisthesis—occurs when one vertebral body shifts posteriorly (toward the back) relative to the adjacent vertebra below. At the L1–L2 level, this means the first lumbar vertebra glides backward over the second. Unlike anterolisthesis (forward slip), retrolisthesis can increase stress on the spinal canal and neural foramina, potentially compressing nerve roots or the spinal cord.

Retrolisthesis is graded by the percentage of displacement:

• Grade I: ≤ 25% of the vertebral body width

• Grade II: 26–50%

• Grade III: 51–75%

• Grade IV: 76–100%

These grades guide clinical decision-making—mild slips are often asymptomatic, while higher grades more frequently cause pain and neurological signs.

• Radiographic studies correlate retrolisthesis at L1–L2 with low back pain and radiculopathy when displacement exceeds 25%.

• Biomechanical analyses show posterior vertebral displacement increases loading forces on facet joints and intervertebral discs.

Anatomy & Pathomechanics

Vertebral Structure at L1–L2

• Bodies: Large, load-bearing cylinders separated by intervertebral discs.

• Facet Joints: Posterior articulations that guide and limit motion.

• Ligaments: The posterior longitudinal ligament (PLL) and ligamentum flavum stabilize against excessive backward translation.

• Neural Elements: The L2 nerve roots exit just below L2; slip at L1–L2 can narrow the neural foramen.

Disc and Joint Mechanics

When the disc degenerates (loses height, hydration), and facet joints arthrose, the vertebral segment can lose its normal alignment. A combination of:

• Disc wedging

• Facet joint laxity

• Capsular ligament weakening
  permits a posterior glide (retrolisthesis) under load—particularly when lifting, bending, or twisting.

Types of L1–L2 Retrolisthesis

Though all involve posterior translation, retrolisthesis can be subclassified by cause, chronicity, and direction:

A. By Etiology

1. Degenerative Retrolisthesis

   • Mechanism: Age-related wear of disc and facets leads to posterior slippage.

   • Features: Gradual onset in middle to older adults; often bilateral facet joint osteoarthritis.

2. Traumatic Retrolisthesis

   • Mechanism: Acute injury (e.g., hyperflexion or compression fracture) disrupts bony or ligamentous structures.

   • Features: Sudden back pain post-trauma; potential for associated fractures.

3. Pathologic Retrolisthesis

   • Mechanism: Tumors, infections (osteomyelitis), or metabolic bone disease (e.g., osteoporosis) weaken structural integrity.

   • Features: Systemic signs (fever, weight loss) or low bone density on imaging.

4. Iatrogenic Retrolisthesis

   • Mechanism: Surgical over-resection of facets or lamina (e.g., wide laminectomy) destabilizes the segment.

   • Features: Occurs weeks to months post-spine surgery; may present as new or worsening back pain.

5. Congenital/Dysplastic Retrolisthesis

   • Mechanism: Developmental anomalies of facets or pars interarticularis misalignment from birth.

   • Features: Detected in adolescents or young adults; may coexist with other spinal anomalies.

B. By Chronicity

• Acute (< 3 weeks): Often traumatic, severe pain, local muscle spasm.

• Subacute (3–12 weeks): May follow minor injury on a degenerating spine; pain begins to localize.

• Chronic (> 12 weeks): Adaptation with potential facet joint remodeling; pain may fluctuate with activity.

C. By Grade of Displacement

• Grade I (Mild): ≤ 25%; often incidental; minimal neural compression.

• Grade II (Moderate): 26–50%; more likely to cause mechanical pain and foraminal narrowing.

• Grade III (Severe): 51–75%; high risk of neurological symptoms; may need surgical consideration.

• Grade IV (Complete): > 75%; essentially complete posterior dislocation; usually unstable; surgery often indicated.
