What is hemilaminectomy?

Hemilaminectomy is a surgical procedure that involves the removal of a portion of the lamina, a part of the vertebral arch, on one side of the spine. This surgery is typically performed to relieve pressure on the spinal cord or spinal nerves caused by conditions such as herniated discs or spinal stenosis. By accessing the affected area through a small incision, surgeons can alleviate pain and improve mobility for patients. The procedure is often considered when conservative treatments have failed to provide relief.
