This dissertation presented the latest results regarding implementing Augmented and Mixed Reality Head-Mounted Displays in spine surgery, focusing on clinical accuracy, surgeon workload, usability, and benchmarking metrics. Through a systematic review and workload analysis study, AR/MR-HMD systems like xVision or HoloLens-based navigation and guidance demonstrated high pedicle screw placement accuracy (GRS A+B > 98.5%), reduced radiation exposure, and minimal disruption to surgical workflow.
Usability studies using the SURG-TLX framework revealed that AR/MR-HMDs decrease mental demand and distraction, especially among junior surgeons (0–6 years), who reported the lowest overall workload scores. Surgeons in mid (7–15 years) and senior (16+ years) experience groups perceived higher physical and temporal burden, indicating the need for ergonomic refinements and adaptive interfaces. Cross-speciality use further validated the broad applicability of AR/MR-HMDs in digital surgery.
The dissertation also introduced a novel multidimensional 3D benchmarking framework combining accuracy, operative time, and radiation exposure. This was enhanced by a proposed User Satisfaction Score (USS), enabling comprehensive evaluation of surgical navigation systems. Additionally, the research highlighted the underdeveloped field of Situation Awareness in AR/MR-HMD literature and advocated for integrating standardised measurement tools like SAGAT, eye-tracking, or EEG.
Technical benchmarks for clinical-grade AR/MR-HMDs were outlined, recommending features such as a wide field of view, IP65-rated casings, ergonomic design, and seamless OR integration. These findings guide future development, validation, and regulation of AR/MR-HMD platforms in surgery.
In conclusion, AR/MR-HMD systems present a viable, scalable alternative to robotic guidance. They offer ergonomic, cognitive, and cost-efficiency benefits and are particularly beneficial for younger surgeons. With continued development in SA metrics and interface design, AR/MR-HMDs are positioned to become key tools in the future of digital and minimally invasive surgery.
