What is a lumbar disc replacement?
Replaces a selected painful lumbar disc with an artificial disc designed to preserve motion. Through an anterior approach, the damaged lumbar disc is removed and an artificial disc is placed between the vertebral bodies. Access planning accounts for the abdominal vessels and prior surgery.
Conditions it treats
Am I a candidate?
A carefully selected patient with disc-related pain, preserved facet joints, suitable alignment, and no major instability may be considered after conservative care fails.
How the diagnosis and surgical level are confirmed
Lumbar disc replacement requires confidence that a selected disc is a meaningful pain source and that the anatomy can support motion preservation. Degenerative MRI changes alone are not enough. The workup considers facet health, alignment, instability, stenosis, bone quality, number of painful levels, abdominal surgical history, and the position of major vessels. It also considers pain from facets, sacroiliac joints, hips, or non-spinal sources. Through the anterior corridor, the disc is removed and the supporting bone prepared for a properly sized and centered device; safe access and endplate protection take priority over preserving motion. Early care includes the abdominal incision, bowel function, leg and foot examination, and approach-related symptoms. Trades and patient-care work reintroduce bending, rotation, lifting, and carrying only after movement quality and implant assessment. An artificial disc cannot recreate normal biology or guarantee pain relief, and wear, movement, unwanted bone formation, or facet pain may complicate revision.
How Dr. Merola performs lumbar disc replacement
Through an anterior approach, the damaged lumbar disc is removed and an artificial disc is placed between the vertebral bodies. Access planning accounts for the abdominal vessels and prior surgery.
Recovery timeline and returning to work
Walking begins early, followed by staged core and mobility work. Return to heavier work depends on the approach, implant position, strength, and functional recovery.
Alternatives and related procedures
Anterior lumbar fusion removes the disc and joins the level; disc replacement aims to preserve motion. Anatomy, facet health, instability, and pain source guide the choice.
Lumbar Disc Replacement risks and outcomes
Risks include vascular or nerve injury, infection, implant movement or wear, heterotopic bone, persistent pain, and revision surgery.

How do I know whether I need a lumbar disc replacement?
A carefully selected patient with disc-related pain, preserved facet joints, suitable alignment, and no major instability may be considered after conservative care fails. The decision follows a direct examination and review of imaging, symptoms, prior care, health, and functional limits.
What happens during a lumbar disc replacement?
Through an anterior approach, the damaged lumbar disc is removed and an artificial disc is placed between the vertebral bodies. Access planning accounts for the abdominal vessels and prior surgery. The exact levels and approach are individualized, and Dr. Merola performs the operation personally.
How long is recovery after a lumbar disc replacement?
Walking begins early, followed by staged core and mobility work. Return to heavier work depends on the approach, implant position, strength, and functional recovery. Timing still varies with the approach, levels treated, healing, neurologic findings, and job demands.
What are the alternatives to a lumbar disc replacement?
Anterior lumbar fusion removes the disc and joins the level; disc replacement aims to preserve motion. Anatomy, facet health, instability, and pain source guide the choice. Non-surgical care may remain reasonable when the examination and imaging support it.
What risks should I understand before a lumbar disc replacement?
Risks include vascular or nerve injury, infection, implant movement or wear, heterotopic bone, persistent pain, and revision surgery. Symptoms may improve incompletely, and additional care or surgery may be needed. No result is guaranteed.
