Risk Factors for Tibial Plafond Nonunion: Medial Column Fixation May Reduce Nonunion Rates

Objectives: To identify the incidence and risk factors for development of tibial plafond nonunion. Design: Retrospective comparative study. Setting: Two Level 1 academic trauma centers. Patients/Participants: Seven hundred forty tibial plafond fractures (OTA/AO 43B3 and 43C) treated January 2006 to December 2015. Intervention: Open reduction and internal fixation. Main Outcome Measurement: Nonunion. Results: Five hundred eighteen patients with a mean age of 43 years (range, 18–81 years) and mean follow-up of 27 months (range, 12–115 months) were involved. Seventy-two patients (72/518, 14%) were identified as having a nonunion. Surgical approach was not associated with nonunion in univariate analysis. Multiple regression model 1 identified OTA/AO 43C [odds ratio (OR) = 4.43; 95% confidence interval (CI), 1.01–19.41; P = 0.048], tobacco use (OR = 2.02; 95% CI, 1.10–3.71; P = 0.024), both minimal and substantial bone loss (P = 0.006 and P
