The anterior approach to lumbar fusion.
What ALIF is, why an anterior approach may be chosen, and how your two surgeons work together. General information, not medical advice.
Fusion performed from the front.
Anterior Lumbar Interbody Fusion reaches the lumbar spine through the abdomen rather than the back, giving the spine surgeon direct visualization of the disc space and vertebral bodies.
Reaching that corridor safely is the access surgeon’s work.
The goal is to stabilize a painful or unstable spinal segment; in selected cases ALIF may also restore disc height or alignment. Expected benefits vary by diagnosis and should be discussed with your treating spine surgeon.
- 01
Direct disc access
The front of the lumbar spine is reached without disrupting posterior stabilizing muscles.
- 02
Surrounded anatomy
Major vessels and abdominal structures sit directly over the operative corridor.
- 03
Specialized exposure
Careful mobilization and retraction are distinct from the fusion and involve specific risks.
Two surgeons, one operative plan.
Spine Surgeon
Performs the fusion: disc preparation, implant placement, and anterior column reconstruction.
Access Surgeon
Creates and maintains the operative pathway, protecting vascular and abdominal structures throughout.
Every case is reviewed before the day of surgery.
Imaging, prior abdominal procedures, and vascular anatomy inform the access strategy well ahead of the operating room.
Access risks can include bleeding, infection, wound problems, hernia, blood clots, or injury to nearby vessels, bowel, ureter, or nerves. In some men, ejaculation can change. Your team can explain how your anatomy and surgical history affect these risks.
Questions to discuss with your physician
- Why is fusion recommended in my situation?
- Why is the anterior approach appropriate for my anatomy?
- Who is on my surgical team, and what is each role?
- What preparation and recovery should I expect?
- Are there alternative approaches to consider?
