Early experience with the Autophor prosthesis using a posterior approach.

S A Stuchin, V H Frankel

    The Yale Journal of Biology and Medicine
    |November 1, 1984
    PubMed
    Summary

    The Autophor hip prosthesis shows early success in 25 patients, particularly for young individuals or those with bone loss. While some complications occurred, most patients achieved stable bony fixation within six months.

    Hip arthroplasty with a collared straight cobalt-chrome femoral stem using second-generation cementing technique: a 10-year-average follow-up study.

    The Journal of arthroplasty·2000

    Area of Science:

    • Orthopedic Surgery
    • Biomedical Engineering

    Background:

    • Hip replacement surgery is a common procedure for treating debilitating hip joint conditions.
    • The Autophor hip prosthesis is a specific implant system designed for hip arthroplasty.
    • Assessing the early outcomes and complications of novel hip implants is crucial for surgical practice.

    Purpose of the Study:

    • To evaluate the initial clinical outcomes and complication rates of the Autophor hip prosthesis.
    • To determine the implant's survivorship and bony integration in a patient cohort.
    • To identify patient populations that may benefit most from this specific hip implant.

    Main Methods:

    • A retrospective review of 28 Autophor hip prostheses implanted in 25 patients.
    • Primarily utilized a posterior surgical approach for implantation.
    • Followed patients clinically and radiologically, including bone scans, to assess fixation and complications.

    Main Results:

    • Two dislocations (one requiring reoperation) and two femoral shaft fractures were observed.
    • Femoral shaft fractures healed within three months with bone grafting and cerclage wiring.
    • No infections, loosening, or component failures were reported; radiological follow-up indicated bony stabilization by six months.

    Conclusions:

    • The Autophor hip prosthesis demonstrates promising early success, with a low rate of major complications.
    • The implant appears particularly suitable for young patients and those with significant bone stock loss, such as in protrusio acetabuli or revision surgery.
    • Further long-term studies are warranted to confirm the durability and overall efficacy of the Autophor hip prosthesis.
