A surgical procedure that is a particular type of fusion that permanently fuses, or unites, the bones of the spine is called transforaminal interbody lumbar fusion. The fusion is achieved using a bone graft: bone material either acquired from a bone bank or transplanted from elsewhere in the patient’s own body.

An interbody fusion is a spinal fusion that involves removing the intervertebral disk. Thus, it creates a space wherein it is implanted with a bone spacer between the two adjoining vertebrae.
