    Long-term clinical and histological evaluation of bioceramic total hip endoprostheses.

    Orthopedics·2014

    Bioceramic endoprostheses were implanted in 155 patients for hip diseases and bone tumors. Ceramic material complications included head breakage, cup loosening, and pseudarthrosis, with abrasion particles found in all cases.

    Area of Science:

    • Biomaterials Science
    • Orthopedic Surgery
    • Oncology

    Background:

    • Bioceramic endoprostheses were utilized between 1974 and 1980.
    • Implantations addressed degenerative hip diseases and malignant bone tumors.
    • A combination of ceramic and metal components was common.

    Purpose of the Study:

    • To analyze complications specifically related to bioceramic materials in endoprostheses.
    • To evaluate the outcomes of bioceramic implants in hip joint and tumor cases.

    Main Methods:

    • Retrospective analysis of 155 patients receiving bioceramic endoprostheses.
    • Review of complications including ceramic head breakage, cup loosening, and pseudarthrosis.
    • Histological examination for abrasion particles.

    Main Results:

    • Complications observed: 8 ceramic head breakages, 13 ceramic cup loosenings, 9 pseudarthroses in tumor endoprostheses.
    • Follow-up periods averaged 22 months for tumor endoprostheses and 24 months for hip joint endoprostheses.
    • Abrasion particles were identified in all histologically examined cases.

    Conclusions:

    • Bioceramic endoprostheses present specific material-related complications.
    • Further investigation into wear debris and material integrity is warranted.
