A slipped disc, also known as a herniated disc, occurs when a portion of the spinal disc is displaced, typically due to it being forced through a weakened area of the spine.
Understanding Your Spinal Discs
Before understanding how they slip, it's essential to know what spinal discs are. These crucial components of your spine are designed for cushioning and flexibility:
- Composition: Spinal discs are made up of a jelly-like substance contained within a tougher outer ring.
- Function: They act as natural cushions between the vertebrae (bones) of your spine, allowing for movement and absorbing shock during daily activities.
The Mechanism of a Slipped Disc
A slipped disc happens due to a specific mechanical failure within the spinal structure. Based on the provided information, the process is straightforward:
- Disc Displacement: A herniated disc occurs when all or part of a disc is forced through a weakened part of the spine.
- Location of Weakness: This "weakened part" can be due to various factors, including wear and tear from aging, injury, or repetitive strain that compromises the disc's outer layer.
- Consequence: When the disc material is pushed out of its normal position, it may place pressure on nearby nerves or the spinal cord. This pressure is often the cause of pain, numbness, or weakness experienced by individuals with a slipped disc.
The lower back is the area most commonly affected by herniated discs, though they can occur anywhere along the spine.
