Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Anatomical Research

Background:

  • Direct surgical access to the entire contents of long bones can be challenging and risky.
  • Current methods may not adequately address the epiphysis or deep marrow cavity.
  • Minimally invasive techniques are increasingly sought after in orthopedic procedures.

Purpose of the Study:

  • To develop a minimally invasive technique for accessing the entire contents of long bones.
  • To enable access to the marrow cavity and epiphysis through a percutaneous approach.
  • To establish an alternative method for treating bone lesions.

Main Methods:

  • Utilized vascular catheterization techniques for marrow cavity access.
  • Developed a novel device to reach the epiphysis of long bones.

Related Experiment Videos

  • Performed ex vivo experiments on animal and human anatomical specimens using endoscopic principles.

    • Main Results:

    • Successfully demonstrated access to the entire marrow cavity via a minimal percutaneous approach.
    • Validated the functionality of the new device for reaching the epiphysis.
    • Established the feasibility of the technique on anatomical specimens.

    Conclusions:

    • The developed technique provides a minimally invasive method for accessing long bone contents.
    • This approach can serve as a valuable alternative when direct access to bone lesions is dangerous or impossible.
    • Potential applications include preventive cement injections in weakened bones.
