Computer-Aided Orthopedic Surgery (CAOS) uses navigation systems to enhance surgical accuracy and visibility by linking bone anatomy to virtual models. This technology, including image-free and image-based systems, is increasingly used in operating rooms.

Area of Science:

  • Orthopedic Surgery
  • Medical Technology
  • Surgical Navigation

Background:

  • Computer-Aided Orthopedic Surgery (CAOS) aims to improve surgical precision and visualization.
  • It links patient's bony anatomy to a virtual representation for guidance.
  • Navigation systems and smart end-effectors are key components of CAOS.

Purpose of the Study:

  • To introduce the fundamental principles of Computer-Aided Orthopedic Surgery (CAOS).
  • To classify surgical navigation systems based on their virtual representation methods.
  • To highlight the technological challenges and orthopedic applications of CAOS.

Main Methods:

  • Classification of surgical navigation systems into image-free and image-based categories.
  • Discussion of preoperative and intraoperative image-based technologies (CT, fluoroscopy).

Related Experiment Videos

  • Presentation of enabling technologies and their development challenges.

    • Main Results:

    • Surgical navigation systems enhance accuracy and visibility in orthopedic procedures.
    • Image-based systems, particularly CT and fluoroscopy, are established in operating rooms.
    • Various orthopedic applications across different anatomical areas are feasible with CAOS.

    Conclusions:

    • CAOS principles are crucial for advancing orthopedic surgical techniques.
    • Modern tracking technologies enable sophisticated navigation systems.
    • Continued development of enabling technologies will expand CAOS applications in orthopedics.
