Abstract
- <bold>Background Context: </bold>Preoperative TNF-AI use has been associated with increased rate of postoperative infections and complications in a variety of orthopedic procedures. However, the association between TNF-AI use and complications following spine surgery has not yet been studied.<bold>Purpose: </bold>The purpose of the present study was to assess the risk of reoperation in patients prescribed TNF-AI undergoing spinal fusion surgery.<bold>Study Design: </bold>This is a retrospective review.<bold>Patient Sample: </bold>A total of 427 patients who underwent spinal fusion surgery at a large healthcare system from 1/1/2009 to 12/31/2018.<bold>Outcome Measure: </bold>Reoperation within 1 year.<bold>Methods: </bold>We retrospectively reviewed the records of patients who underwent spinal fusion surgery at a large healthcare system from 1/1/2009 to 12/31/2018. There were three distinct cohorts of spine surgery patients under study: patients with TNF-AI use in 90 days before surgery, patients with non-TNF-AI DMARD medications use in the 90 days before surgery, and patients taking neither TNF-AI nor other DMARD medications in 90 days before surgery. The primary outcome of interest was reoperation for any reason within 1 year following surgery.<bold>Results: </bold>Our study included 90 TNF-AI, 90 DMARD, and 123 control patients. Reoperation up to 1-year postsurgery occurred in 19% (n=17) of the TNF-AI group, 11% (n=10) of the DMARD group, and 6% (n=7) of the control group. The reasons for reoperation for TNF-AI group were 47% (n=8) infection and 53% (n=9) other causes which included failure to fuse and adjacent segment disease. Reasons for reoperation at 1 year were 40% (n=4) infection and 60% (n=6) other causes for DMARD patients and 14% (n=1) infection with 86% (n=6) other causes for control patients. The cox-proportional hazard model of reoperation within 1 year indicated that the odds of reoperation were 3.1 (95% CI:1.4-7.0) and 2.2 (95% CI 0.96-5.3) times higher in the TNF-AI and DMARD groups, respectively, compared to the control group.<bold>Conclusions: </bold>Patients taking TNF-AIs before surgery were found to have a significantly higher rate of reoperation in the 1 year following surgery compared to controls. The higher rate of reoperation associated with TNF-AI use before spinal fusion surgery represents the potential for higher morbidity and costs for patient which is important to consider for both surgeon and patient in preoperative decision making.
