What is a lumbar foraminotomy?
Widens the exit channel for a compressed lumbar nerve to address radiating leg symptoms. Dr. Merola removes the bone or soft tissue narrowing the foramen while preserving stabilizing structures when possible. A fusion is considered only when decompression would leave the segment unstable.
Conditions it treats
Sciatica
Radiating leg pain has a cause. Finding it is the first step.
Learn more →Spinal Stenosis
When the spinal canal narrows, the goal is to give the nerves room.
Learn more →Herniated Disc
Back and leg pain that travels. Most herniated discs improve without surgery.
Learn more →Spondylolisthesis
A slipped vertebra is often stable and treatable without surgery.

It may be considered when foraminal stenosis matches leg pain, numbness, or weakness and conservative care has not restored function.
How the diagnosis and surgical level are confirmed
The target is foraminal stenosis affecting a named lumbar nerve, rather than broad central-canal narrowing. Strength, sensation, reflexes, walking, and tension signs are matched to the level and side on imaging. Hip disease, vascular symptoms, and peripheral neuropathy can resemble lumbar root compression and must remain in the differential. Disc-height loss, a slip, or motion under load may show that adequate decompression would remove too much supporting facet and that fusion deserves comparison. Bone, ligament, or disc material is removed according to where the root is constrained. Office work advances with sitting breaks; driving requires reliable pedal control; delivery, nursing, sanitation, and construction add twisting, uneven ground, repetition, and unpredictable lifting. Opening the foramen cannot repair an already injured nerve or prevent further degeneration. Persistent symptoms may reflect chronic nerve damage, another pain source, recurrent narrowing, or instability rather than an automatically incomplete operation.
How Dr. Merola performs lumbar foraminotomy
Dr. Merola removes the bone or soft tissue narrowing the foramen while preserving stabilizing structures when possible. A fusion is considered only when decompression would leave the segment unstable.
Recovery timeline and returning to work
Walking begins early. Desk work and light duty generally precede repetitive bending, lifting, and full physical work, with timing based on symptoms and stability.
Alternatives and related procedures
Microdiscectomy removes a focal disc fragment; laminectomy treats central narrowing; fusion is reserved for instability or deformity that decompression alone cannot address.
Lumbar Foraminotomy risks and outcomes
Risks include infection, nerve injury, spinal fluid leak, recurrent narrowing, persistent symptoms, instability, and later surgery.

How do I know whether I need a lumbar foraminotomy?
It may be considered when foraminal stenosis matches leg pain, numbness, or weakness and conservative care has not restored function. The decision follows a direct examination and review of imaging, symptoms, prior care, health, and functional limits.
What happens during a lumbar foraminotomy?
Dr. Merola removes the bone or soft tissue narrowing the foramen while preserving stabilizing structures when possible. A fusion is considered only when decompression would leave the segment unstable. The exact levels and approach are individualized, and Dr. Merola performs the operation personally.
How long is recovery after a lumbar foraminotomy?
Walking begins early. Desk work and light duty generally precede repetitive bending, lifting, and full physical work, with timing based on symptoms and stability. Timing still varies with the approach, levels treated, healing, neurologic findings, and job demands.
What are the alternatives to a lumbar foraminotomy?
Microdiscectomy removes a focal disc fragment; laminectomy treats central narrowing; fusion is reserved for instability or deformity that decompression alone cannot address. Non-surgical care may remain reasonable when the examination and imaging support it.
What risks should I understand before a lumbar foraminotomy?
Risks include infection, nerve injury, spinal fluid leak, recurrent narrowing, persistent symptoms, instability, and later surgery. Symptoms may improve incompletely, and additional care or surgery may be needed. No result is guaranteed.
