Sternal Wound ComplicationsObesity (Body Mass Index >30 kg/m2)Median SternotomyCardiac Surgery
Study summary
This retrospective study compares two sternal closure techniques-standard stainless-steel wires and rigid cable systems-in adult patients with a body mass index (BMI) ≥30 who underwent open-heart surgery between January 1, 2020, and December 31, 2024. The study aims to evaluate the incidence of sternal instability, wound infections, reoperation, and length of stay in the intensive care unit and hospital. Findings may help inform surgical decision-making for high-BMI patients.

Primary outcome measure(s)
Incidence of Sternal Instability and Major Wound Complications — 90 days after surgery This outcome measures the rate of sternal instability (e.g., dehiscence, nonunion, displacement requiring intervention) and major sternal wound complications (e.g., deep sternal wound infection, mediastinitis, or reoperation for closure failure) in patients with BMI ≥30 undergoing open-heart surgery. The results will be compared between patients whose sternum was closed with standard stainless-steel wire versus those treated with a multifilament sternal cable system.
