Area of Science:

  • Orthopedic Surgery
  • Medical Robotics
  • Surgical Navigation

Background:

  • Computer-assisted surgery (CAS) integrates robotic and image-guided technologies into orthopedics.
  • Navigation and robotic systems represent advanced CAS components with expanding applications.
  • Surgical navigation provides real-time positional data for surgical tools and implants relative to bone targets.

Purpose of the Study:

  • To review current computer-assisted surgery systems in orthopedics.
  • To discuss the potential and limitations of CAS technologies.
  • To explore future directions and innovations in CAS for improved patient outcomes.

Main Methods:

  • Classification of surgical navigation systems based on planning methods: volumetric image-based, fluoroscopic, and imageless navigation.
  • Categorization of robotic systems by function: guide-directing, movement-constraining, and active automated systems.
  • Review of existing CAS technologies, including specific examples like ACROBOT, ROBODOC, and CASPAR.

Main Results:

  • CAS systems offer enhanced precision over manual surgical tool positioning.
  • Different navigation and robotic systems provide varying levels of guidance and automation.
  • The review covers the capabilities, drawbacks, and future prospects of CAS in orthopedics.

Conclusions:

  • CAS technologies, including navigation and robotics, are advancing orthopedic surgery.
  • Continued development in CAS promises improved patient outcomes and cost-effectiveness.
  • Future research should focus on refining CAS for greater precision and broader clinical adoption.
