Anterior Lumbar Interbody Fusion (ALIF)

Anterior Lumbar Interbody Fusion (ALIF)

Spine Fusions are performed to correct problems with vertebrae in the spine, such as degenerative disc disease, spine instability, and fractures.

An interbody fusion involves removing a degenerated or herniated disc, and replacing it with a metal or plastic artificial disc or a bone graft. The process “tricks” the body into thinking it has a fracture, by joining bone with bone graft, in order to spur bone growth.

Where an ALIF is Performed

Though there are many different methods to perform fusions, an anterior lumbar interbody fusion is performed from the front, in an incision near the belly button.

Why an Anterior Lumbar Interbody Fusion?

The goal of an ALIF is to remove pressure off spinal nerves and increase stability. The procedure is most used when multiple degenerative or herniated discs must be removed or fused together. After an ALIF, you’ll experience increased spine stability and reduced pain.

How an ALIF is Performed

  1. Dr. Valente and his vascular surgeon operate together to access the spine.
  2. To take the pressure off the pinched nerves, the degenerated or herniated disc is then removed.
  3. A bone graft spacer block is then inserted in the disc space.
  4. The two vertebrae will grow into the bone graft to create a solid fusion of the two bones.
  5. A small titanium plate and screws are often used to hold the bone graft in place.
  6. The patient will experience increased spine stability and reduced pain at that segment.
