Study Notes
Lumbar Disc Herniation
- Lumbar disc herniation occurs 15 times more often than other types of disc herniation.
Location of Herniation
- 90-95% of lumbar herniations occur at L4-L5 to S1 levels.
Age of Onset
- Most disc herniations occur when a person is in their thirties or forties.
Prevalence of Sciatica
- 4.8% of males and 2.5% of females older than 35 experience sciatica during their lifetime.
Structure of Intervertebral Disc
- The intervertebral disc is a hydrostatic, load-bearing structure between the vertebral bodies from C2-3 to L5-S1.
Risk Factors for Herniated Discs
- A sedentary lifestyle can lead to herniated discs as weakened back and neck muscles increase strain on the spine.
- Obesity can quicken spinal degeneration due to the burden of supporting excess body weight.
- Practicing poor posture strains the back and neck.
- Tobacco abuse can weaken the disc by interfering with its ability to absorb nutrients.
- Genetic mutations involved in regulating the extracellular matrix can contribute to lumbar disc degeneration.
Learn about the common forms of disc herniation in the spine, including lumbar disc herniation and cervical disc herniation. Understand the risk factors, prevalence, and common causes of lower back pain associated with this condition.
