LAMINECTOMY VS. HEMILAMINECTOMY
“Hemilaminectomy means only half of the lamina is removed. This is a slightly smaller surgery than a laminectomy. Usually a laminectomy is for spinal stenosis vs. a hemilaminectomy for a disc herniation.”
—Dr. Michael Ramsey
Laminectomy involves a surgical procedure to create space by removing the back part of a vertebra that covers the spinal canal, known as the “lamina”. The addition of the prefix “hemi”, which means half, doesn’t change much. In fact, the addition of “hemi” changes less as a hemilaminectomy removes less bone. A Hemilaminectomy means the partial removal of the lamina to decompress the spinal canal. This procedure may also be referred to as decompression surgery. The goal of a hemilaminectomy or decompression procedure: to enlarge the spinal canal and take pressure off the spinal cord or nerves.
Patients may need a hemilaminectomy if conservative treatments fails to relieve the pain. Initially, physicians may attempt treatments such as medication, physical therapy, and injections to help relieve the pressure on the spinal canal. A spine surgeon, a PM&R (Physical Medicine and Rehabilitation) doctor, or a Interventional Pain Management Anesthesiologist may oversee Conservative treatments for spinal stenosis. Bony overgrowths within the spinal canal often cause the need for a laminectomy or a partial hemilaminectomy. These overgrowths cause the spinal canal to narrow which can put pressure on the nerves known as stenosis. This narrowing can result in pain, weakness, or numbness that radiates down your arms or legs.Your provider may recommend a laminectomy if:
Conservative treatment, such as medication or physical therapy, fails to improve your symptoms
You have muscle weakness or numbness that makes standing or walking difficult
You experience loss of bowel or bladder control.
