Navigation System
Computer-assisted surgical technology that provides real-time guidance for implant positioning and bone preparation.
Full Definition
Navigation systems are computer-assisted surgical technologies that provide real-time, three-dimensional guidance during orthopedic procedures to improve accuracy of implant positioning, bone cuts, and anatomical reconstruction. These systems typically use infrared cameras to track surgical instruments and patient anatomy, displaying live feedback on computer monitors. Navigation is particularly valuable in complex procedures such as total joint arthroplasty, spinal instrumentation, and tumor resections where precise positioning is critical for optimal outcomes.
Usage
Usage note: Distinguish from robotic systems which provide active assistance.
