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.

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.
