Disc Herniation<\/h1>\n\n\n\n

Intervertebral discs are fibrocartilaginous cushions between vertebrae, containing a central nucleus pulposus (90% water) and a peripheral annulus fibrosus. Degeneration due to prolonged load, poor posture, and physical strain can weaken the annulus fibrosus, leading to herniation. Herniated nucleus pulposus compresses spinal cord and\/or nerve roots, causing symptoms.<\/p>\n\n\n\n

Classification<\/strong><\/strong><\/p>\n\n\n\n

Based on location:<\/p>\n\n\n\n

    \n
  • Intracanal<\/strong> herniation:<\/strong><\/mark> nucleus pulposus projects into the spinal canal<\/li>\n\n\n\n
  • Intraforaminal<\/strong> herniation:<\/strong><\/mark> nucleus pulposus migrates into the neural foramen<\/li>\n\n\n\n
  • Extraforaminal <\/strong>herniation:<\/strong><\/mark> nucleus pulposus migrates laterally to the neural foramen<\/li>\n<\/ul>\n\n\n\n

    Based on nucleus pulposus protrusion:<\/p>\n\n\n\n

      \n
    • Disc protrusion<\/strong>:<\/mark><\/strong> annulus fibrosus deforms without rupture<\/li>\n\n\n\n
    • Contained herniation<\/strong>:<\/mark><\/strong> nucleus pulposus protrudes into the spinal canal but is contained by the posterior longitudinal ligament<\/li>\n\n\n\n
    • Extruded herniation<\/strong>:<\/mark><\/strong> nucleus pulposus ruptures through the annulus fibrosus and posterior longitudinal ligament<\/li>\n<\/ul>\n\n\n\n

      Causes<\/strong><\/strong><\/p>\n\n\n\n

      Excessive spinal load from physical labor, trauma, sports, sedentary lifestyle, obesity, genetic predisposition, and smoking.<\/p>\n\n\n\n

      Symptoms<\/h2>\n\n\n\n

      Cervical Disc Herniation<\/strong><\/strong><\/p>\n\n\n\n

        \n
      • Spinal cord compression: neck pain, upper\/lower limb weakness, gait difficulty, urinary retention, constipation<\/li>\n\n\n\n
      • Nerve root compression: neck to arm pain, arm\/hand numbness, muscle weakness<\/li>\n<\/ul>\n\n\n\n

        Thoracic Disc Herniation<\/strong><\/strong><\/p>\n\n\n\n

          \n
        • Spinal cord compression: back pain, lower limb weakness, gait difficulty, urinary retention, constipation, reduced sensitivity below compression<\/li>\n\n\n\n
        • Nerve root compression: back pain, intercostal pain, intercostal numbness<\/li>\n<\/ul>\n\n\n\n

          Lumbar Disc Herniation<\/strong><\/p>\n\n\n\n

            \n
          • Nerve root compression: low back pain radiating to the leg, leg\/foot numbness, muscle weakness<\/li>\n<\/ul>\n\n\n\n

            Diagnosis<\/h2>\n\n\n\n

            MRI and CT scans confirm diagnosis, and electromyography (EMG) identifies affected nerve roots.<\/p>\n\n\n\n

            Treatment<\/h2>\n\n\n\n

            Most herniations resolve with conservative treatment (medication, physical therapy). Surgery (5-10% cases) is needed for motor deficits, severe pain, or incontinence, involving removal of herniated disc material to resolve nerve\/spinal cord compression. Procedures include:<\/p>\n\n\n\n

            Cervical Herniation Surgery:<\/strong><\/p>\n\n\n\n

            Anterior approach with intervertebral disc removal and replacement with a titanium\/PEEK prosthesis.<\/p>\n\n\n\n

            Thoracic Herniation Surgery:<\/strong><\/p>\n\n\n\n

            Lateral\/antero-lateral approach, possibly involving partial rib removal or trans-thoracic approach with thoracic surgeons.<\/p>\n\n\n\n

            Lumbar Herniation Surgery:<\/strong><\/p>\n\n\n\n

            Posterior approach with small incision for herniated fragment removal.<\/p>\n<\/div>\n<\/div>\n\n\n\n
