Hemilaminectomy

A hemilaminectomy is a spinal surgical procedure in which part of the vertebral lamina is removed from one side of the vertebra. The purpose of the operation is to decompress nerves or the spinal cord when they are compressed by a herniated disc, spinal stenosis, or other spinal conditions. This technique is considered less invasive than a full laminectomy, as it preserves more of the spine’s natural stability. It is commonly performed in cases causing severe pain, numbness, or neurological symptoms.
