Learn About ALIF Surgery

In an Anterior Lumbar Interbody Fusion (ALIF) surgery, the patient lies supine (face up) and an access surgeon will expose the spine from the anterior side of the abdomen. The spine surgeon will then remove the disc material to prepare the disc space for the interbody. A stand-alone ALIF system may be used (like CoreLink’s M3 system) or an interbody and posterior screws (like CoreLink’s Tiger system) or anterior plate (like CoreLink’s Zou system) may also be placed to help stabilize the spine.


This approach may be used for cases of degenerative disc disease (DDD) of the lumbar spine.

Spondylolisthesis or retrolisthesis

Spondylolisthesis causes the forward motion (or slip) of one vertebral body over the one below it. This can be caused by a traumatic accident or from degenerative disc disease (DDD). DDD can also cause retrolisthesis, which is a vertebral body slipping backward.

Degenerative Disc Disease (DDD)

Degenerative disc disease (DDD) is attributed to age and general wear and tear that presents in the disc area with herniated discs or osteophytes (bone spurs). These can cause collapse and pressure on the nerve roots and/or spinal cord. In the lumbar spine, this occurs most often due to load on the lower spine. This could be due to weight, gravity, or lifting as the lumbar spine carries 80% of body weight when standing.



Depending on the issue, an ALIF surgery may be an option when non-surgical techniques do not relieve symptoms. The primary goals are to decompress neural elements, restore height/lordosis, and stabilize/fuse the spine.
