LaminectomyA laminectomy/discectomy is a procedure in which a disc fragment (herniation) is removed from the spinal canal. A laminectomy without disc removal is performed in cases of spinal stenosis. This procedure is indicated when conservative non-operative treatment measures have failed.
Once asleep and positioned in the operating room, the nurse will cleanse the back with antiseptic solution. The surgeon will perform the surgery with X-ray verification of the level of the disc or nerve problem. The surgeon will make a small incision on the back and dissect the tissues in order to access the spine. The ligament lining over the nerve sac is dissected and the nerves identified. The blood vessels are cauterized and the herniation exposed. The disc fragment(s) are carefully removed with small forceps under loupe magnification. The space for the nerves is enlarged by removing portions of bony and ligamentous structures. The nerves may be coated with anti-adhesion or steroid preparations. The deep tissues are sutured back into anatomic alignment. The skin is closed with a surgical closure. The procedure can also be performed with an endoscope. This approach minimizes scar, as well as the muscle disruption from more open procedures. After your surgery, you may need to stay in the hospital for overnight observation. You should be able to walk several hours after the procedure. |

This
is an MRI image of a large extruded disc herniation that occurred at the L4/L5
level. This case involved progressive weakness along the L5 nerve root
distribution. Surgery in the form of a laminectomy with discectomy was
recommended.
