Verifying the effectiveness of a computer-aided navigation system for arthroscopic hip surgery

Area of Science:

• Minimally Invasive Surgery
• Medical Technology
• Surgical Navigation Systems

Background:

• Arthroscopic surgery offers benefits over traditional open procedures but limits surgeon's view.
• Limited visibility in hip arthroscopy can increase surgical difficulty.
• Computer-aided systems can enhance visualization and precision in minimally invasive procedures.

Purpose of the Study:

• To evaluate the effectiveness of a computer-aided system for hip arthroscopy.
• To determine if the system reduces task completion time and tool path length.
• To verify the system's ability to compensate for limited joint visibility.

Main Methods:

• A user study involving ten participants was conducted.
• Participants performed a simple navigation task with and without the computer-aided system.
• The system tracks tool position using encoders and indicates it relative to patient anatomy.

Main Results:

• The computer-aided system reduced task completion time by 38%.
• Tool path length was decreased by 72% with the system's assistance.
• These results confirm the system's effectiveness in improving surgical navigation.

Conclusions:

• Computer-aided technology significantly enhances hip arthroscopy.
• The developed system improves surgical efficiency and precision.
• This technology addresses key challenges in minimally invasive hip surgery.
