What is an anterior lumbar fusion?
Stabilizes one or more lumbar levels through an approach from the front of the spine. The damaged disc is removed through an abdominal approach, a spacer and bone graft are placed, and fixation is used according to the surgical plan. An access surgeon may participate when appropriate.
Conditions it treats
Am I a candidate?
It may be considered for painful disc degeneration, instability, deformity, spondylolisthesis, or reconstruction when anterior access provides the needed disc height and alignment.
How the diagnosis and surgical level are confirmed
Anterior lumbar fusion offers broad access to the disc space for reconstruction of height, alignment, and stability without working through posterior muscle or scar. The assessment correlates symptoms with collapse, foraminal narrowing, a slip, motion, prior fusion, and adjacent-joint health. Prior abdominal surgery and vascular anatomy influence whether this corridor is reasonable. The disc is removed, the supporting surfaces are prepared, and a spacer with graft restores the planned geometry. Anterior, posterior, or combined fixation depends on the level, bone quality, deformity, and stability; the cage supports the reconstruction but does not replace biologic union. Early observation includes bowel function, abdominal wound, leg neurologic status, and vascular or approach-related symptoms. Commuting adds braking and vehicle entry before office duties; construction and patient care add core loading, carrying, pushing, and pulling. Fusion sacrifices motion and may not eliminate pain from other structures. Nonunion, approach symptoms, implant problems, or adjacent-level disease can prolong care.
How Dr. Merola performs anterior lumbar fusion
The damaged disc is removed through an abdominal approach, a spacer and bone graft are placed, and fixation is used according to the surgical plan. An access surgeon may participate when appropriate.
Recovery timeline and returning to work
Walking begins early, while lifting and core loading return gradually. Fusion is followed over months, and physical work resumes on a plan matched to bone healing and job demands.
Alternatives and related procedures
Posterior fusion approaches the spine from the back; disc replacement preserves motion in selected cases; combined anterior and posterior reconstruction may be used for complex instability or deformity.
Anterior Lumbar Fusion risks and outcomes
Risks include infection, vascular or nerve injury, nonunion, implant complications, approach-related symptoms, adjacent-level stress, and further surgery.

Lumbar Disc Replacement
Replaces a selected painful lumbar disc with an artificial disc designed to preserve motion.

Minimally invasive decompression for selected patients with herniated-disc nerve pain.
Compare procedure →Why go in from the front
The disc lives at the front of the spine, so approaching from the front means arriving where the problem is, through a corridor that leaves the back muscles untouched.
Two practical consequences follow. The graft and cage sit where the disc actually lived, which is mechanically the right seat for them. And the back muscles, the ones that ache after posterior surgery, are largely left alone.
Trade-offs exist and get said out loud: an approach through abdominal territory, with its own risks, and the small scar most patients gladly trade. For single and double level disease with the right anatomy, it is a clean solution, sometimes combined with a posterior stage for fixation. The disc replacement page describes the motion-preserving cousin of this operation.
This is routine territory for a spine surgeon who has been seeing New York patients for over 30 years.

Frequently Asked Questions
How do I know whether I need an anterior lumbar fusion?
It may be considered for painful disc degeneration, instability, deformity, spondylolisthesis, or reconstruction when anterior access provides the needed disc height and alignment. The decision follows a direct examination and review of imaging, symptoms, prior care, health, and functional limits.
What happens during an anterior lumbar fusion?
The damaged disc is removed through an abdominal approach, a spacer and bone graft are placed, and fixation is used according to the surgical plan. An access surgeon may participate when appropriate. The exact levels and approach are individualized, and Dr. Merola performs the operation personally.
How long is recovery after an anterior lumbar fusion?
Walking begins early, while lifting and core loading return gradually. Fusion is followed over months, and physical work resumes on a plan matched to bone healing and job demands. Timing still varies with the approach, levels treated, healing, neurologic findings, and job demands.
What are the alternatives to an anterior lumbar fusion?
Posterior fusion approaches the spine from the back; disc replacement preserves motion in selected cases; combined anterior and posterior reconstruction may be used for complex instability or deformity. Non-surgical care may remain reasonable when the examination and imaging support it.
What risks should I understand before an anterior lumbar fusion?
Risks include infection, vascular or nerve injury, nonunion, implant complications, approach-related symptoms, adjacent-level stress, and further surgery. Symptoms may improve incompletely, and additional care or surgery may be needed. No result is guaranteed.
What is an anterior lumbar interbody fusion?
An operation that reaches the disc space from the front, through a small abdominal corridor, removes the diseased disc, and places a cage and graft to fuse the level. Approaching from the front preserves the back muscles and lets the cage sit where the disc actually lived.
Is it normal to have a scar after low back spinal fusion surgery?
Yes. Front-side approaches leave a small horizontal scar on the abdomen; posterior approaches leave one over the spine. Scars fade; the trade for the corridor is part of the consent conversation.
How much does spinal fusion surgery cost in the USA?
Published averages wander wildly because they mix one-level and multilevel cases, different implants, and different settings. The number that matters is yours, with your plan, and the office works that out with you before anything is scheduled. Call (718) 783-5542.
