Rigid sternal fixation improves postoperative recovery.

INTRODUCTION: During the past five years, ridged sternal fixation has been utilized for sternal closure after cardiac surgery. It is known that this procedure provides better sternal stability; however, its contribution to patient recovery has not been investigated. METHODS: Retrospective chart review was conducted for patients who underwent CABG and/or valve surgery in our institution between 2009 and 2010. Preoperative, perioperative, and follow-up data of patients with ridgid fixation (group R, n=89) were collected and compared with those patients with conventional sternal closure (group C, n=133). The decision regarding the sternal closure method was based on the surgeon\u27s preferences. Univariate followed by multivariate analyses were performed to evaluate the dominant factor of sternal lock usage and to evaluate postoperative recoveries. The factors included in the analyses were; age, sex, coronary risk factors, urgency of surgery, ejection fraction, coronary anatomy, preoperative stroke, renal function, and preoperative presence of heart failure. All statistical analyses were performed by JMP software. RESULTS: Group R was younger (62 ± 9 in group R vs 69 ± 11 in group C, p CONCLUSION: Rigid sternal fixation systems were more frequently applied to low risk young male patients. Among these selected patients, ridgid sternal fixation can contribute to early patient recovery
