    Area of Science:

    • Orthopedic surgery
    • Biomaterials science
    • Surgical innovation

    Background:

    • Interfragmental compression is crucial for primary bone healing in fractures.
    • Current sternal closure methods, particularly wire closure, represent a significant weakness in fixation stability.
    • Existing techniques often fail to utilize the full tensile strength of surgical wires.

    Purpose of the Study:

    • To introduce and evaluate the Controlled Tension Osteosynthesis System for sternal closure.
    • To address the limitations of traditional wire closure methods in sternotomy procedures.
    • To enhance fixation stability and promote optimal bone healing through improved osteosynthesis.

    Main Methods:

    • Development of an anchor plate system for sternal wire closure.

    Related Experiment Videos

  • Tensile testing of the anchor plate closure compared to traditional wire twist closure.
  • Utilizing a high-tensile strength steel alloy wire in conjunction with the anchor plate.
  • Application of the anchor plate using a specialized instrument, the Strainsqueezer.

    • Main Results:

    • The anchor plate closure retains up to 80% of the wire's tensile strength, compared to 20-33% for wire twist closure.
    • Combined use of the anchor plate and high-strength wire resulted in a sevenfold to ninefold increase in fixation stability.
    • The Strainsqueezer facilitated controlled and standardized clinical application of the anchor plate.
    • The system minimizes foreign body material by using a thin, prestressed wire.

    Conclusions:

    • The Controlled Tension Osteosynthesis System provides superior compression osteosynthesis fixation for sternal closure.
    • This innovative system significantly improves fixation stability, offering a more robust alternative to conventional methods.
    • The development is supported by extensive clinical experience, indicating its practical efficacy and potential for widespread adoption in sternotomies.
