Augmented Reality‐Based Femur Registration With Head‐Mounted Display and Infrared Tracking Device as Stand‐Alone Navigation Tool: A Preclinical Validation Study

Key Points

• Accurate registration performance shows a mean target registration error (TRE) of ~3 mm across various approaches, meeting clinical application standards.
• Validation methods included the use of a head-mounted display with an infrared tracking device to assess registration consistency among users.
• The promising results indicate that the augmented reality system could serve as a navigation tool for surgeries like total hip arthroplasty.
• Further cadaveric study is necessary to better understand surgical feasibility and how this technology can apply in actual operations.
