Lumbar Disc Herniation (Herniated Lumbar Disc)

Function of the Discs

  • The discs between the vertebrae allow spinal mobility and act as shock absorbers that bear weight.

  • The outer part of the disc (annulus fibrosus) is tough, while the inner part (nucleus pulposus) is soft and gel-like.

Causes of Lumbar Disc Herniation

  • Mechanical Strain: Heavy lifting, poor posture, sudden movements.

  • Aging: Discs lose water content, become more prone to wear and tear or rupture.

  • Trauma: Accidents or falls.

  • Genetic Predisposition: Some individuals have a higher risk of disc degeneration.

Symptoms

Local Symptoms:

  • Lower back pain

  • Pain that increases with movement

Nerve Compression Symptoms:

  • Pain radiating to the buttock, leg, or foot (sciatica)

  • Numbness or tingling (paresthesia)

  • Muscle weakness

Severe Cases (Cauda Equina Syndrome):

  • Loss of bladder or bowel control

  • Severe weakness in the legs

  • Requires emergency surgery

Diagnostic Methods

  • Physical Examination: Assessment of nerve function

  • Magnetic Resonance Imaging (MRI): Detailed imaging of the disc

  • Computed Tomography (CT): Detailed view of the bony structures

  • Electromyography (EMG): Measures the extent of nerve compression

Treatment Options

Conservative (Non-Surgical) Treatment:

  • Physical Therapy: Exercise programs, heat-cold applications

  • Medical Treatment: Pain relievers, muscle relaxants, steroids

  • Injections: Epidural steroid injections

Surgical Treatment (Rare Cases):

  • For neurological deficits or persistent pain unresponsive to conservative treatment

  • Microdiscectomy: Removal of herniated disc material

  • Lumbar Fusion: Complete disc removal and spinal stabilization

Prevention

  • Proper Posture and Ergonomics: Protect the lower back when lifting heavy objects

  • Regular Exercise: Strengthen core and lower back muscles

  • Weight Control: Excess weight increases pressure on the spine

Prognosis

Most cases of lumbar disc herniation improve with conservative treatment. However, surgery may be required in cases of significant nerve compression or permanent neurological deficits.
