    Area of Science:

    • Biomedical Engineering
    • Materials Science
    • Orthopedic Surgery

    Background:

    • Aseptic prosthetic instability is a frequent and severe complication following endoprosthesis surgery, often necessitating revision surgery.
    • Current endoprosthesis designs face challenges in long-term stability and integration with the human body.

    Purpose of the Study:

    • To develop a novel endoprosthesis design and surgical procedure inspired by the functional similarity between human teeth and endoprostheses.
    • To investigate the efficacy of endoprostheses with dumping elements in preventing aseptic instability.

    Main Methods:

    • A long-term surgical experiment was conducted to develop and test the endoprosthesis procedure.
    • Evaluation techniques included X-ray, bed testing, light microscopy, and scanning electron microscopy.
    • Prostheses were coated with polytetrafluoroethylene velour in experiments and cauflene in clinical settings.

    Main Results:

    • Experimental results demonstrated the effectiveness of the developed endoprosthesis design and procedure.
    • The study yielded two patented inventions in the Russian Federation.
    • The innovative design shows promise in mitigating aseptic endoprosthetic instability.

    Conclusions:

    • The functional analogy between human teeth and endoprostheses provides a basis for advanced prosthetic design.
    • Endoprostheses incorporating dumping elements represent a fruitful direction for preventing aseptic instability.
    • This research offers a promising strategy to reduce the incidence of revision surgeries due to prosthetic complications.
