This procedure corrects the spinal condition caused by spondylolisthesis, in which weakened joints or fractured bones allow a vertebra to slip forward and pinch a nerve root. the pinched nerve can cause pain to radiate down to the legs and feet through the sciatic nerve.
In this procedure, the surgeon removes the portion of the vertebra that covers the spinal cord, called the lamina, to relieve pressure and pain. Next, the surgeon takes away any bone that may be pinching the nerve root. then bone grafts are added to the spine to fuse to the spine, forming solid bone. Rods are secured to the spine with screws to hold the spine and discs in place while the grafts heal.
