    Crimped steel plate sternal fixation significantly reduces sternal dehiscence after sternotomy compared to wire sutures. This surgical technique improvement enhances patient outcomes and reduces reoperation rates.

    Area of Science:

    • Cardiovascular Surgery
    • Thoracic Surgery
    • Biomedical Engineering

    Background:

    • Sternal dehiscence is a serious complication following sternotomy.
    • Traditional sternal closure methods, like wire sutures, have limitations.

    Purpose of the Study:

    • To compare the efficacy of crimped steel plate fixation versus twisted sternal wire sutures in preventing sternal dehiscence.
    • To identify risk factors associated with sternal dehiscence.

    Main Methods:

    • Retrospective analysis of 4,531 patients undergoing sternotomy over eight years.
    • Comparison of sternal closure techniques: wire sutures (years 1-4) and steel plate fixation (years 5-8).
    • Statistical analysis to determine the incidence of sternal dehiscence and associated factors.

    Main Results:

    • Sternal dehiscence incidence decreased significantly from 17/1,000 patients with wire sutures to 3/1,000 patients with steel plate fixation.
    • Male gender was common among affected patients (35/36); 4 required reoperation for bleeding.
    • Factors like mammary artery dissection, tracheostomy, and high body weight were not significant predictors.

    Conclusions:

    • Crimped steel plate fixation is a superior method for sternal closure, markedly reducing dehiscence rates.
    • Early reoperation with antibiotic irrigation is effective in managing sternal dehiscence and achieving wound stability.
    • While infection can occur, it is often secondary to dehiscence, and chronic osteomyelitis is manageable.
