| Abstract: | Introduction: Percutaneous screw fixation of the pelvis is a difficult procedure with risks of neurovascular damage. The corridors are narrow and an error of a maximum of 2 mm is permitted. In the Radboudumc this procedure is often executed with the 3D-navigation system of Brainlab. The most significant disadvantage of this system is the constant switching between the surgical field and the computer monitors, which increases the cognitive load for the surgeon. To attack this problem, a new surgical navigation technique using augmented reality with infrared marker tracking is introduced. Methods: A reference star and phantom were designed and 3D printed to attach the infrared markers. An algorithm to detect infrared markers with the HoloLens 2 was developed and an augmented reality application was built for a simulated surgical procedure. The aim of the simulation was to place five K-wires into 5 rings with the guidance of the augmented reality application. Five participants performed the experiment. One participant did the experiment 3 times. The placed and planned K-wires were analyzed. Hit/no hit, ∆ Euclidean distance of entry point and endpoint, and the angle were evaluated. Results: The phantom was 3D printed and the maximum error of the virtual and physical measurements combined was 0.43 mm. The prototype of the augmented reality application was successfully developed. The IR marker tracking accuracy was 1.44±0.33 mm. The results of the experiment were as follows: 69% of the placed K-wires went through the rings, the mean error of the ∆entry point was 2.57 mm, the mean error of the ∆endpoint was 4.71 mm, and the mean error of the angle was 4.68 mm. For the ∆endpoint and angle, data of the no hits were not included and considered outliers. Conclusion: This study provides a proof of concept for performing percutaneous screw fixation of the pelvis using augmented reality with IR marker tracking as guidance. A simplification of the procedure was performed. Further research is needed to improve the accuracy of the AR application. This can be done by improving the segmentation, registration, and calibration of the augmented reality application. On top of that, adding tool tracking to the augmented reality application should also increase the accuracy. More research is needed to further improve the phantom and the experiment before this surgical navigation technique can be implemented clinically. |
