Laminectomy : A procedure where the surgeon removes a part of vertebra (lamina) to relieve back pain. When there is a compression, the disk, piece of bone, tumor or other structure is removed to relieve the pressure. The doctor makes a small incision over the targeted vertebra. When the spinal canal is reached after going though the fatty tissue, the bony arch and the ligamentum flavum, the cause of the compression will be visible and can be dealt with.
