välilevyinä

Välilevyinä is a Finnish term that translates to "discs between" and refers to the intervertebral discs. These are the cartilaginous structures located between the vertebrae of the spinal column. Each intervertebral disc consists of two main parts: the annulus fibrosus, which is the tough outer ring, and the nucleus pulposus, which is the gel-like inner core.

The primary function of välilevyinä is to act as shock absorbers for the spine, cushioning the impact of daily activities like walking, running, and lifting. They also provide flexibility and allow for movement of the spine. The discs contribute to the overall height of a person and play a crucial role in maintaining spinal stability.

Problems with välilevyinä can lead to various issues, most commonly back pain. Conditions such as herniated discs, also known as slipped discs or prolapsed discs, occur when the nucleus pulposus bulges or ruptures through the annulus fibrosus. This can put pressure on nearby nerves, causing pain, numbness, or weakness. Degenerative disc disease is another common condition where the discs lose hydration and begin to break down over time, leading to reduced shock absorption and potential pain. Treatment for välilevyinä issues can range from conservative methods like physical therapy and pain medication to more invasive options such as surgery.
