Advanced Spinal Reconstruction Procedure Now Available in The Northland

August 16, 2023

Dr. Matthew T. Davies, a Board Certified and Fellowship Trained Neurosurgeon recently performed the first Multi-Level Lumbar Disc Replacement in The Northland using Centinel Spine’s prodisc® L Total Disc Replacement (TDR) technology.  The prodisc® L system is the only total disc replacement device in the U.S. approved for two-level use in the lumbar spine. 

Whereas lumbar disc replacement was previously only FDA approved for single-level problems, Centinel Spine’s clinically proven prodisc® L Total Disc Replacement (TDR) technology received FDA approval for two-level implantation in 2020.  Many patients who previously were not candidates will now have access to this life-changing procedure.  Lumbar Total Disc Replacement offers a surgical alternative to spinal fusions in the lumbar spine and works to relieve pain in patients suffering from degenerated spinal discs, while maintaining motion over the long term at the diseased spinal segment, and reducing adjacent-level degeneration and re-operations.

The prodisc® L TDR is an alternative to spinal fusion surgery. It enables motion within the spine— rather than fusing the motion segments together, which can result in a decrease in mobility. Even in the short- to medium-term, a comparative five-year study showed a three times lower likelihood of adjacent level degeneration in those patients receiving the prodisc® L total disc replacement versus those who received a fusion2. (Adjacent-level degeneration was characterized by a composite score including disc height loss, endplate sclerosis, osteophytes, and spondylolisthesis.)

As spine treatments continue to advance through innovative technologies and motion preserving techniques, patients are seeking out alternatives to fusions.  “With newly approved two-level use for prodisc L, more of my patients will be able to benefit from disc replacement technology, which enables motion in the diseased segment of the spine,” stated Dr. Davies. “Using a minimally-invasive anterior approach, my patients also benefit from a much faster recovery and return to active life, while decreasing the likelihood of adjacent level degeneration.”

Dr. Davies went on to say, “Most people over the age of 40 have some degree of degeneration in their spine—it is just a part of the aging process. Many younger patients have pain due to back injury.  For those patients who don’t respond to non-surgical means of managing their pain, disc replacement surgery can be a successful option.” 

The prodisc® L system received one-level FDA approval in 2006 and since 2020 is the only total disc replacement device in the U.S. approved for two-level use in the lumbar spine. Recent expanded insurance coverage for lumbar TDR with the prodisc® L device has contributed even more to my patient’s ability to have this procedure.

For today’s patient looking forward to a speedy recovery to an active life-style, prodisc® L is a powerful treatment option worthy of consideration for appropriate patients.  For more information about Total Disc Replacement or to schedule a consultation with Dr. Matthew T.
