Use of longitudinal rigid sternal fixation in prevention and treatment of wound complications among high‐risk patients after cardiac surgery

Background Traditionally, wire cerclage closure has been used to reapproximate the sternum after cardiac surgery. Recent evidence suggests that rigid sternal fixation may reduce the risk of wound complications. The aim of this study was to analyze our 10‐year experience with longitudinal rigid sternal fixation (LRSF) for prevention and treatment of wound complications in high‐risk patients. Methods We reviewed data from cardiac surgical database of patients who underwent LRSF, and compared their outcomes with conventional wire cerclage closure (CWS). Among these 319 patients were designated as having high‐risk for the development of deep wound complications and received primary LRSF (treatment group). We matched their outcomes with 319 patients who met indications for LRSF however, underwent standard closure with CWC (control group). Results Both groups were comparable regarding preoperative and intraoperative variables. The benefit observed among matched patients who had undergone LRSF was largely driven by a decreased rate of deep wound infections (0.63% vs. 3.45% vs., p
