Lumbar Total Disc Replacement
This is a surgical procedure to remove a diseased or degenerated lumbar intervertebral disc and replace it with an artificial disc implant. Unlike traditional spinal fusion, TDR preserves motion at the operated disc segment.
Imaging studies (x-ray, MRI, CT) are used to identify the degenerated disc level, assess spinal alignment, and rule out contraindications such as severe facet joint disease. In surgery, the patient is positioned supine for an anterior (front) approach for direct access to the disc space. The diseased intervertebral disc is carefully removed, preserving surrounding bone and ligaments. The artificial disc is sized and inserted into the disc space; it’s designed to replicate motion while maintaining disc height and spinal alignment. The incision is closed, typically leaving a small anterior abdominal scar.
Who Is a Candidate?
Lumbar total disc replacement (TDR) may be recommended for patients with chronic low back pain caused by degenerative disc disease that has not improved with conservative treatments such as physical therapy, medications, or spinal injections. Candidates typically have pain originating from one or two damaged lumbar discs without significant arthritis of the facet joints. To ensure the best possible outcome, patients should not have significant spinal instability, osteoporosis, or conditions such as spondylolisthesis. Your spine specialist will perform a comprehensive evaluation to determine whether lumbar disc replacement is the right treatment option for your condition.
Lumbar total disc replacement may be appropriate for patients who have:
Chronic low back pain caused by degenerative disc disease
Pain isolated to one or two lumbar disc levels
Little to no significant facet joint arthritis
Not experienced adequate relief with conservative treatment
Good spinal stability and bone quality
No significant spondylolisthesis or osteoporosis
Benefits
Lumbar total disc replacement offers several potential benefits for appropriately selected patients, including:
Preserves natural motion at the treated spinal level, unlike spinal fusion
Reduces stress on adjacent discs, which may lower the risk of adjacent segment disease
Provides lasting pain relief for many patients with degenerative disc disease
Restores disc height to help relieve pressure on surrounding nerves
Improves spinal alignment and posture
Minimally invasive anterior approach with a smaller incision and less disruption to the back muscles compared to traditional posterior fusion surgery
Road to Recovery
Recovery after lumbar total disc replacement is gradual, with most patients walking shortly after surgery and returning to normal activities over the following weeks. Your surgeon will provide personalized guidance throughout each stage of recovery.
What to Expect
Hospital stay: Typically 1–3 days
Walking: Encouraged the day of surgery
Light activities: May resume in 2–4 weeks
Physical therapy: Begins within a few weeks to restore strength and stability
Full recovery: Most patients reach maximum improvement within 3–6 months
Follow-up care: Routine imaging monitors healing and implant position
