Augmented reality assisted orthopaedic surgery.

[摘要] ENGLISH SUMMARY: The aim of this study was to investigate the clinical e cacy and feasibilityof an application of augmented reality assisted orthopaedic surgery (ARAOS)technology that focuses on supporting and enhancing current best practicesin orthopaedic surgery. Through consultation with a representative from theAdvanced Orthopaedic Training Centre at Tygerberg Hospital, wrist replacementsurgery was chosen as the clinical problem on which to focus. A work owaimed at providing maximum bene t for these types of procedures was conceptualisedwhich involved making use of the two surgically removed bones topredict the remaining geometry by incorporating a statistical shape model intoa shape estimation process. A simulated procedure based around one aspect ofwrist replacement surgery was designed which allowed for a comparison to bemade between using conventional navigational methods and that of using ARguidance to assist with surgical navigation. The results from this experimentindicate marginally inferior accuracy compared to the more conventionaluoroscopicguidance. However, a reduction in procedural time, and a relativelyshort learning curve (intuitiveness) was observed when using AR guidance.Furthermore, with AR navigational assistance, both the patient and the surgeonare not exposed to harmful ionising radiation sources. In conclusion, it isthe author's opinion that ARAOS technology appears to show clinical e cacyand feasibility for use in the operating room with potential to support and enhancecurrent best practises in orthopaedic surgery while remaining a ordableand potentially more intuitive than other forms of navigational assistance.
