Item Open Access Acute Hip Pain in the Nonambulatory Infant(Pediatric Emergency Care, 2006-05) Gross, Shari L; Orndorff, Douglas G; Romness, Mark; Poelstra, Kornelis AItem Open Access Five-year durability of stand-alone interspinous process decompression for lumbar spinal stenosis(Clinical Interventions in Aging) Nunley, Pierce D; Patel, Vikas V; Orndorff, Douglas G; Lavelle, William F; Block, Jon E; Geisler, Fred HItem Open Access Interspinous Process Decompression Improves Quality of Life in Patients with Lumbar Spinal Stenosis(Minimally Invasive Surgery, 2018-07-02) Nunley, Pierce D; Patel, Vikas V; Orndorff, Douglas G; Lavelle, William F; Block, Jon E; Geisler, Fred HLumbar 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.Item Open Access Intrawound Vancomycin Decreases the Risk of Surgical Site Infection After Posterior Spine Surgery: A Multicenter Analysis.(Spine, 2018-01) Devin, Clinton J; Chotai, Silky; McGirt, Matthew J; Vaccaro, Alexander R; Youssef, Jim A; Orndorff, Douglas G; Arnold, Paul M; Frempong-Boadu, Anthony K; Lieberman, Isador H; Branch, Charles; Hedayat, Hirad S; Liu, Ann; Wang, Jeffrey C; Isaacs, Robert E; Radcliff, Kris E; Patt, Joshua C; Archer, Kristin RStudy design
Secondary analysis of data from a prospective multicenter observational study.Objective
The aim of this study was to evaluate the occurrence of surgical site infection (SSI) in patients with and without intrawound vancomycin application controlling for confounding factors associated with higher SSI after elective spine surgery.Summary of background data
SSI is a morbid and expensive complication associated with spine surgery. The application of intrawound vancomycin is rapidly emerging as a solution to reduce SSI following spine surgery. The impact of intrawound vancomycin has not been systematically studied in a well-designed multicenter study.Methods
Patients undergoing elective spine surgery over a period of 4 years at seven spine surgery centers across the United States were included in the study. Patients were dichotomized on the basis of whether intrawound vancomycin was applied. Outcomes were occurrence of SSI within postoperative 30 days and SSI that required return to the operating room (OR). Multivariable random-effect log-binomial regression analyses were conducted to determine the relative risk of having an SSI and an SSI with return to OR.Results
.: A total of 2056 patients were included in the analysis. Intrawound vancomycin was utilized in 47% (n = 966) of patients. The prevalence of SSI was higher in patients with no vancomycin use (5.1%) than those with use of intrawound vancomycin (2.2%). The risk of SSI was higher in patients in whom intrawound vancomycin was not used (relative risk (RR) -2.5, P < 0.001), increased number of levels exposed (RR -1.1, P = 0.01), and those admitted postoperatively to intensive care unit (ICU) (RR -2.1, P = 0.005). Patients in whom intrawound vancomycin was not used (RR -5.9, P < 0.001), increased number of levels were exposed (RR-1.1, P = 0.001), and postoperative ICU admission (RR -3.3, P < 0.001) were significant risk factors for SSI requiring a return to the OR.Conclusion
The intrawound application of vancomycin after posterior approach spine surgery was associated with a reduced risk of SSI and return to OR associated with SSI.Level of evidence
