What is a laminectomy?

A laminectomy is specifically defined as a surgical procedure that involves the removal of the lamina, which is the thin, bony layer that covers the back of the vertebrae. This procedure is typically performed to relieve pressure on the spinal cord or nerves, often due to conditions such as spinal stenosis, herniated discs, or to remove tumors or bone spurs that may be causing pain or neurological symptoms.

By removing the lamina, the surgeon increases the space within the spinal canal, providing more room for the spinal cord and nerves, which can alleviate symptoms such as pain, numbness, and weakness in the limbs. The focus on surgical intervention is key, as it addresses structural issues within the spine that may be contributing to a patient's condition.

Understanding this procedure is important for recognizing how surgical options can enhance overall spinal health, contrasting with other choices that refer to replacement, therapy, or enhancement methods rather than direct surgical intervention on the vertebrae.
