The surgeon makes a small incision along the midline of the lower back. Muscles surrounding the spine are pulled back to expose the vertebrae.
Removal of Lamina
The surgeon then removes the lamina, which is the bone that covers the spinal cord. Removal of lamina relieves the pressure on the nerve roots and alleviates pain.
Removal of herniated disc and fragments
Next, the surgeon clears away any herniated disc, fragments, or bones that may be pinching the root nerves.
Bone graft is added to the sides of the spine. The bone grafts will fuse to the spinal cord and form a solid bone bridge.
Insertion of screws and rods
The surgeon then adds screws and rods. Screws help to secure the rods that hold the spinal cord, discs and vertebrae in place while the graft heals. Over time, the bone graft will fuse with the spine and keep the discs from slipping.
The procedure ends when the surgeon moves the muscles back to their correct place and closes the wound. The incision is closed with the help of stitches. A medical bandage is applied after cleaning the wound.
