A surgical technique used to join two vertebrae. Spinal fusion may include the use of bone graft with or without instrumentation (eg, rods, screws). There are different types of bone graft, such as your own bone (autograft) and donor bone (allograft). A fusion can be accomplished by different approaches:

• Anterior Lumbar Interbody Fusion

• Posterior Lumbar Interbody Fusion

• Transforaminal Lumbar Interbody Fusion indicates a surgical approach through the foramen.

• Lateral Interbody Fusion in which the minimally invasive approach is from the side of the body.
