What is a minimally invasive lumbar fusion?
Stabilizes selected lumbar levels through smaller working corridors when that approach can meet the full surgical goal. Using image guidance and limited muscle corridors where appropriate, Dr. Merola performs decompression, places fixation, and adds bone graft to support fusion.
Conditions it treats
Am I a candidate?
It may be considered for selected instability, spondylolisthesis, recurrent stenosis, disc collapse, or deformity when the anatomy and number of levels support a limited approach.
How the diagnosis and surgical level are confirmed
This technique changes access to a lumbar fusion but not its essential goals: correct diagnosis, adequate nerve decompression, sound fixation, useful alignment, and living bone union. Imaging and examination define the slip, motion, collapse, recurrent stenosis, deformity, and nerve pattern. The number of levels, correction required, prior scar, body anatomy, bone quality, and location of compression determine whether limited corridors can complete the plan. Image guidance and muscle-splitting access may assist decompression, interbody work, grafting, and screw placement. Indirect decompression is appropriate only when the anatomy permits it; a constrained nerve may need direct release. Small skin incisions can accompany a substantial internal reconstruction. Remote work first tests sitting and walking, whereas roofing, delivery, nursing, and industrial work adds bending, impact, and unpredictable loads. The approach cannot correct every deformity and does not guarantee less pain, faster union, or shorter work disability.

Recovery timeline and returning to work
Smaller incisions do not eliminate the need for fusion healing. Walking starts early, while lifting and full physical work return on a staged plan over the following months.
Alternatives and related procedures
Open posterior fusion, anterior fusion, decompression alone, or a combined approach may provide better access or correction for other patterns of disease.
Minimally Invasive Lumbar Fusion risks and outcomes
Risks include infection, bleeding, nerve injury, spinal fluid leak, nonunion, implant complications, incomplete correction, and further surgery.

How do I know whether I need a minimally invasive lumbar fusion?
It may be considered for selected instability, spondylolisthesis, recurrent stenosis, disc collapse, or deformity when the anatomy and number of levels support a limited approach. The decision follows a direct examination and review of imaging, symptoms, prior care, health, and functional limits.
What happens during a minimally invasive lumbar fusion?
Using image guidance and limited muscle corridors where appropriate, Dr. Merola performs decompression, places fixation, and adds bone graft to support fusion. The exact levels and approach are individualized, and Dr. Merola performs the operation personally.
How long is recovery after a minimally invasive lumbar fusion?
Smaller incisions do not eliminate the need for fusion healing. Walking starts early, while lifting and full physical work return on a staged plan over the following months. Timing still varies with the approach, levels treated, healing, neurologic findings, and job demands.
What are the alternatives to a minimally invasive lumbar fusion?
Open posterior fusion, anterior fusion, decompression alone, or a combined approach may provide better access or correction for other patterns of disease. Non-surgical care may remain reasonable when the examination and imaging support it.
What risks should I understand before a minimally invasive lumbar fusion?
Risks include infection, bleeding, nerve injury, spinal fluid leak, nonunion, implant complications, incomplete correction, and further surgery. Symptoms may improve incompletely, and additional care or surgery may be needed. No result is guaranteed.
