Rigid Sternal Fixation Versus Modified Wire Technique for Poststernotomy Closures: A Retrospective Cost Analysis

Background: Rigid sternal fixation (RSF) has been shown to reduce sternal wound complications in high-risk patients. However, the higher initial cost continues to deter its use. This study evaluates the cost of caring for high-risk sternotomy patients who underwent RSF compared with those who underwent sternal closure with a modified wire technique (MWT). Methods: A retrospective single institution review of high-risk patients who underwent MWT (n = 45) and RSF (n = 30) for primary sternal closure from 2006 to 2009 was conducted. Total hospital cost, revenue, and net cost associated with surgery and subsequent care were analyzed. Results: Overall rates of wound dehiscence and wound infections (superficial and deep) were higher in MWT patients (n = 14, 13, and 7, respectively) than RSF patients (n = 3, 2, and 0, respectively; P
