Digital injury using the sternum perforating awl.

M E Lee

    The Annals of Thoracic Surgery
    |April 1, 1979

    Summary

    A plastic guard can prevent digital injuries caused by sternum-perforating awls snapping during median sternotomy closure. This simple modification enhances surgical safety for this common cardiac procedure.

    Area of Science:

    • Cardiovascular Surgery
    • Surgical Instrumentation
    • Patient Safety

    Background:

    • Median sternotomy is a standard surgical approach for cardiac procedures.
    • Closure involves passing wires through the sternum using a sternum-perforating awl.
    • Sudden snapping of the awl shaft during penetration poses a risk of digital injury to the surgeon.

    Purpose of the Study:

    • To identify a method for preventing digital injuries during median sternotomy.
    • To assess the efficacy of a protective sheath for sternum-perforating awls.

    Main Methods:

    • A protective plastic sheath was designed to cover the shaft of a sternum-perforating awl.
    • The modified awl was evaluated in the context of median sternotomy closure procedures.

    Main Results:

    • The plastic sheath effectively contained the awl shaft if it snapped during sternal penetration.
    • No digital injuries were reported when the sheathed awl was used.

    Conclusions:

    • Sheathing the sternum-perforating awl with a plastic guard is a simple and effective safety measure.
    • This modification can significantly reduce the risk of digital injury during median sternotomy closure.
