Sternalock Versus Wires for Sternal Closure Study

Design: Investigator Initiated Prospective Randomised Trial Study Centre's: Melbourne Private Hospital Royal Melbourne Hospital Study Hypothesis: Use of the SternaLock 360 will reduce the incidence of sternal motion \> 2mm by absolute difference of 40% at 6 weeks of surgery compared to stainless steel wiring. Use of the SternaLock 360 will improve bone healing and quality of recovery after surgery compared to stainless steel wiring Study Objective: To determine if the SternaLock 360 system reduces sternal instability, increases bone healing, and improves quality of recovery compared to stainless steel wiring of the sternum, after cardiac surgery involving median sternotomy Inclusion Criteria: Age ≥ 18 year old Elective cardiac surgery Primary cardiac surgical procedure No evidence of infection at time of surgery Sufficient English language to complete the Postoperative Quality of Recovery Survey Exclusion Criteria: Previous sternotomy (redo) Clinical sternal deformity Home locality preventing follow-up (e.g. remote regional, interstate or overseas patient) Number of Planned Subjects: 50
