Disc herniation
Disc Herniation
Disc herniation (pronunciation: /dɪsk hɜːrˈneɪʃən/) is a medical condition affecting the spine, where a tear in the outer, fibrous ring (annulus fibrosus) of an intervertebral disc (Intervertebral disc) allows the soft, central portion (nucleus pulposus) to bulge out beyond the damaged outer rings.
Etymology
The term "disc herniation" comes from the Latin words "discus", meaning "disc", and "hernia", meaning "protrusion".
Symptoms
Symptoms of disc herniation can vary depending on the location and size of the herniation. They may include pain in the back or neck, numbness or tingling, muscle weakness, and difficulty moving or walking.
Causes
Disc herniation is often the result of a gradual, aging-related wear and tear called disc degeneration. As you age, your intervertebral discs lose some of their water content, which makes them less flexible and more prone to tearing or rupturing with even a minor strain or twist.
Diagnosis
Diagnosis of disc herniation is typically made through a physical examination and imaging tests, such as an MRI (Magnetic resonance imaging) or a CT scan (Computed tomography).
Treatment
Treatment for disc herniation may include conservative measures such as rest, physical therapy, and medication. In more severe cases, surgery (Spinal surgery) may be required.
