What surgical procedure involves the removal of the lamina on vertebral bodies to create space for spinal roots?

The procedure that involves the removal of the lamina, which is part of the vertebral arch, to alleviate pressure on the spinal roots and create more space in the spinal canal is known as laminectomy. This surgical intervention is typically performed in cases where there is spinal stenosis, herniated discs, or other conditions that compress the spinal cord or nerve roots, causing pain or neurological symptoms. By excising the lamina, surgeons aim to decompress the affected nerves, which can provide relief from pain and improve function.

In contrast, herniorrhaphy is a procedure for repairing a hernia, which does not involve the vertebral column. Mastectomy refers to the surgical removal of breast tissue, and hysterectomy involves the removal of the uterus. Neither of these procedures addresses issues related to the spine or spinal roots, making laminectomy the specific procedure related to the removal of lamina.
