Abstract

<jats:p>Lumbar spinal stenosis has been shown to negatively impact health-related quality of life. Interspinous process decompression (IPD) is a minimally invasive procedure that utilizes a stand-alone spacer to serve as a joint extension blocker to relieve neural compression in patients with spinal stenosis. Using the 5-year results from an FDA randomized controlled trial of IPD, the quality of life in 189 patients treated with the Superion® spacer was evaluated with the SF-12. Physical and mental component summary (PCS, MCS) scores were computed preoperatively and at annual intervals. For the PCS, mean scores improved from 29.4 ± 8.1 preoperatively to 41.2 ± 12.4 at 2 years (40%) and to 43.8 ± 11.6 at 5 years (49%) (p<0.001 for both comparisons). At 2 years, 81% (103 of 128) of subjects demonstrated maintenance or improvement in PCS scores. The mean MCS score improved from 50.0 ± 12.7 preoperatively to 54.4 ± 10.6 and 54.7 ± 8.6 at 2 and 5 years, respectively (p>0.10 for both comparisons). These results demonstrate that the significant impairment in physical well-being found in patients with lumbar spinal stenosis can be ameliorated, in large part, by IPD treatment.</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.
