Spinal fusion is a surgical procedure which is performed to correct problems related to the small bones of the spine (vertebrae). This technique principally follows the welding process. That is it requires to simply fuse together the painful vertebrae, so that the healing results in a single, solid bone.
A posterolateral fusion operation is similar to a posterior lumbar interbody fusion (PLIF) ; however, instead of removing the disc space and replacing it with a bone graft, the disc space remains intact and the bone graft is placed between the transverse processes in the back of the spine.n a posterolateral fusion, pedicle screws and rods also may be implanted to stabilize the spine until the bone graft heals. A single-level fusion fuses two vertebrae and usually uses four screws and two rods.
