What is a laminectomy?

A laminectomy is a surgical procedure that involves the excision of the posterior arch of a vertebra. This procedure is typically performed to relieve pressure on the spinal cord or nerves that may occur due to conditions such as spinal stenosis, herniated discs, or tumors. By removing the lamina—the part of the vertebra that forms the back of the spinal canal—surgeons are able to access the spinal canal and address the underlying issues causing pain or neurologic symptoms.

The choice reflecting the excision of the posterior arch correctly captures the primary goal and method of the laminectomy procedure, which is to alleviate pressure on neural structures, improve mobility, and reduce pain for the patient. This approach can lead to significant relief and is an important intervention for various spinal conditions where conservative treatments have failed.
