Välileikkaus

Välileikkaus, also known as a discectomy, is a surgical procedure performed to remove or relieve pressure on a herniated or bulging intervertebral disc in the spine. The intervertebral discs act as cushions between the vertebrae, providing flexibility and absorbing shock. When a disc herniates, the nucleus pulposus protrudes through the annulus fibrosus, potentially compressing nearby nerves and causing pain, numbness, or weakness.

The primary goal of välileikkaus is to alleviate nerve compression and reduce symptoms such as leg pain (sciatica) or back pain. The procedure can be performed using traditional open surgery or through minimally invasive techniques, which involve smaller incisions and specialized instruments. The choice of method depends on the specific case, the location of the herniation, and the patient's overall health.

Välileikkaus is typically considered after conservative treatments, such as physical therapy, medications, or injections, have failed to provide relief. The procedure is generally safe, but risks include infection, nerve damage, bleeding, or dural tears. Recovery times vary, but many patients experience significant symptom improvement within weeks.

The success rate of välileikkaus in relieving pain and restoring function is generally high, although the likelihood of recurrence exists, especially if underlying conditions worsen or if lifestyle factors contribute to disc degeneration. The procedure can be performed at various levels of the lumbar or cervical spine, depending on the affected disc.

In summary, välileikkaus is a common surgical intervention aimed at relieving nerve compression caused by herniated intervertebral discs, with the objective of improving patient quality of life through pain reduction and functional restoration.
