Anterior Lumbar Interbody Fusion (ALIF)
What Is Anterior Lumbar Interbody Fusion?
Anterior Lumbar Interbody Fusion (ALIF) is a surgical procedure used to treat conditions in the lower back (lumbar spine) that cause pain, instability, or nerve compression. In this procedure, a damaged spinal disc is removed and replaced with a bone graft or implant to help stabilize the spine and encourage fusion between two vertebrae.
The term “anterior” means the spine is accessed from the front of the body, usually through a small incision in the abdomen. This approach allows the physician to reach the disc without moving the muscles and nerves of the back.
ALIF is often used when other treatments have not provided relief.
At OIBortho, our physicians evaluate and perform advanced spine procedures, including ALIF, for patients throughout Middlesex, Monmouth, and Ocean Counties.
When Is ALIF Recommended?
ALIF may be recommended when there is significant disc damage or spinal instability that does not improve with non-surgical care.
It may be considered for:
- Degenerative disc disease in the lumbar spine
- Spondylolisthesis (vertebral slippage)
- Chronic lower back pain from disc collapse
- Spinal instability
- Recurrent disc herniation
- Foraminal narrowing causing nerve compression
Symptoms That May Lead to ALIF
Patients who may be considered for ALIF often experience:
- Chronic lower back pain
- Pain that worsens with standing or walking
- Radiating pain into the hips or legs
- Numbness or tingling in the legs or feet
- Muscle weakness in the lower extremities
- Reduced ability to stand upright comfortably
- Pain that does not improve with conservative treatment
Causes of the Conditions Treated
ALIF addresses structural problems in the lumbar spine, including:
- Degenerative disc disease
- Disc collapse
- Spondylolisthesis
- Spinal instability
- Wear-and-tear arthritis of the spine
- Previous disc injuries or surgery
Over time, discs can lose height and cushioning ability, leading to instability and nerve irritation.
How the Procedure Works
During an ALIF procedure:
- A small incision is made in the abdomen
- Muscles and blood vessels are carefully moved aside to access the spine
- The damaged disc is removed
- A bone graft or implant is placed into the disc space
- A device (such as a cage and/or screws) may be used for stability
- Over time, the vertebrae fuse into one solid bone
The anterior approach allows direct access to the disc with minimal disruption to back muscles.
Recovery and What to Expect
Recovery varies depending on the individual and whether additional procedures are performed.
Typical recovery may include:
- Hospital stay for monitoring after surgery
- Early walking soon after surgery
- Gradual return to light activities over several weeks
- Physical therapy to restore strength and mobility
- Full fusion over several months
Many patients experience improvement in stability and pain over time as healing progresses.
Risks and Considerations
ALIF is a major surgery and may include risks such as:
- Infection
- Bleeding
- Blood vessel or organ injury (rare)
- Nerve irritation or injury
- Blood clots
- Non-union (failure of fusion)
- Ongoing or recurrent pain
A physician will review all risks and benefits before recommending surgery.

Frequently Asked Questions
What is ALIF surgery?
ALIF is a procedure that removes a damaged disc in the lower back and fuses the vertebrae through an approach from the front of the body.
Why is the anterior approach used?
It allows access to the spine without moving the muscles of the back, which can reduce disruption to those tissues.
How long does recovery take?
Initial recovery takes weeks, but full fusion of the spine can take several months.
Will I feel better right away?
Some symptoms improve early, but full recovery takes time as the spine heals and fuses.
Is ALIF safe?
Yes, but like all surgeries, it carries risks that should be discussed with a physician.
Who is a candidate for ALIF?
Patients with chronic disc problems, instability, or spondylolisthesis that do not respond to conservative treatment may be candidates.
