["Zuggurtungs"-hip joint endoprosthesis (author's transl)]

Area of Science:

• Orthopedic surgery
• Biomechanical engineering
• Biomaterials science

Background:

• Hip joint replacement is a common procedure to address joint degeneration.
• Loosening and mechanical failure are significant complications in current hip prostheses.
• Existing prostheses often rely on bone cement, which can have long-term issues.

Purpose of the Study:

• To introduce a new hip endoprosthesis model, the "Zuggurtungs-Hüftendoprothese."
• To detail the biomechanical principles underlying the new prosthesis design.
• To present a solution for avoiding mechanical complications in hip replacements.

Main Methods:

• Theoretical and experimental investigations into hip joint biomechanics.
• Development and realization of a novel prosthesis model based on derived biomechanical principles.
• Selection of optimal materials to enhance prosthesis longevity and integration.

Main Results:

• The new "Zuggurtungs-Hüftendoprothese" incorporates specific biomechanically derived features.
• These features are crucial for preventing prosthesis loosening and fracture.
• The design enables stable primary anchorage, facilitating cementless implantation.

Conclusions:

• The developed "Zuggurtungs-Hüftendoprothese" offers a biomechanically sound approach to hip replacement.
• Cementless implantation is achievable due to the stable anchorage provided by the prosthesis design.
• This innovation has the potential to reduce mechanical complications associated with hip endoprostheses.
