    This study outlines the design of a composite elasto-dynamic intervertebral disc prosthesis (IDP). The implant aims for surgical, biomechanical, and biocompatibility requirements, featuring an elastic core and a novel shell design.

    Area of Science:

    • Biomedical Engineering
    • Orthopedic Surgery
    • Materials Science

    Background:

    • Degenerative disc disease necessitates advanced intervertebral disc prostheses (IDPs).
    • Existing IDPs face challenges in achieving optimal biomechanical function and long-term biocompatibility.
    • Elasto-dynamic properties are crucial for mimicking natural disc behavior.

    Purpose of the Study:

    • To discuss essential design considerations for a composite elasto-dynamic intervertebral disc prosthesis (IDP).
    • To outline a novel IDP implant design that addresses surgical, biomechanical, and biocompatibility demands.
    • To present a potential solution for lumbar motion segment restoration.

    Main Methods:

    • Conceptual design and material selection for an elasto-dynamic intervertebral disc prosthesis.
