The goal of this procedure is to stabilise the spine, minimising low back and leg pain. This procedure stops the motion of the affected disc level by placing screws, rods and bone graft to promote the two vertebrae to become one bone (spinal fusion).
Typically two 2-3 cm incisions are made on either side of the lumbar spine. After the incisions are made, a minimally invasive approach is made down to the vertebral body using dilating tubes. The surgeon then ensures that spinal screws are securely placed into the vertebral body of spine. Live x-ray and live nerve monitoring are used to ensure that the screws are placed accurately.
