Interspinous Process Decompression: Expanding Treatment Options for Lumbar Spinal Stenosis
Abstract
<jats:p>Interspinous process decompression is a minimally invasive implantation procedure employing a stand-alone interspinous spacer that functions as an extension blocker to prevent compression of neural elements without direct surgical removal of tissue adjacent to the nerves. The Superion® spacer is the only FDA approved stand-alone device available in the US. It is also the only spacer approved by the CMS to be implanted in an ambulatory surgery center. We computed the within-group effect sizes from the Superion IDE trial and compared them to results extrapolated from two randomized trials of decompressive laminectomy. For the ODI, effect sizes were all<jats:italic>very large</jats:italic>(>1.0) for Superion and laminectomy at 2, 3, and 4 years. For ZCQ, the 2-year Superion symptom severity (1.26) and physical function (1.29) domains were<jats:italic>very large</jats:italic>; laminectomy effect sizes were<jats:italic>very large</jats:italic>(1.07) for symptom severity and<jats:italic>large</jats:italic>for physical function (0.80). Current projections indicate a marked increase in the number of patients with spinal stenosis. Consequently, there remains a keen interest in minimally invasive treatment options that delay or obviate the need for invasive surgical procedures, such as decompressive laminectomy or fusion. Stand-alone interspinous spacers may fill a currently unmet treatment gap in the continuum of care and help to reduce the burden of this chronic degenerative condition on the health care system.</jats:p>

I have over 15 years of experience in private practice spine care, primarily in a small rural town serving a large geographical area. Being one of the few spine surgeons for such a large area allowed me to become adept at recognizing and treating virtually all adult spinal conditions. My goal is to maximize non-surgical options first, with the goal of getting my patients back to the activities they love as fully as possible. I have partnered with top spine companies in the field to develop multiple cutting edge products that are now being used in spine surgeries worldwide. I am particularly interested in motion preservation surgery, improving fusion outcomes, and spine navigation. My treatment philosophy is to engage patients in their own spine health care, working together to tailor the best possible course of action for their individual needs and lifestyle.
