Abstract
Introduction: This study assessed the incidence and risk factors for pseudarthrosis among primary spine fusion patients. Methods: Retrospective review of ACS-NSQIP (2005–2013). Differences in comorbidities between spine fusion patients with and without pseudarthrosis (Pseud, N-Pseud) were assessed using chi-squared tests and Independent Samples t-tests. Binary logistic regression assessed patient-related and procedure-related predictors for pseudarthrosis. Results: 52,402 patients (57yrs, 53%F, 0.4% w/pseudarthrosis). Alcohol consumption (OR:2.6[1.2–5.7]) and prior history of surgical revision (OR:1.6[1.4–1.8]) were risk factors for pseudarthrosis operation. Pseud patients at higher risk for deep incisional SSI (at 30-days:OR:6.6[2.0–21.8]). Pseud patients had more perioperative complications (avg:0.24 ± 0.43v0.18 ± 0.39,p=0.026). Conclusions: Alcoholism and surgical revision are major risk factors for pseudarthrosis in patients undergoing spine fusion.
