The typical fusion is a posterolateral fusion where bone is placed in the bony gutters between the transverse processes. This is the commonest fusion done and involves a large amount of muscle dissection.
Interbody fusions involve the removal of the whole intervertebral disc and bone chips or cages are placed into the cavity. This is a fusion that is technically more demanding to perform but has a higher fusion rate and, for technical reasons, is more versatile.
Facet joint fusions are usually done to supplement interbody fusions and involve the removal of the facet joint capsule and packing the joint with bone graft.
