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.
