Open-source navigation system for tracking dissociated parts with multi-registration

Purpose: During reconstructive surgery, knee and hip replacements, and orthognathic surgery, small misalignments in the pose of prosthesis and bones can lead to severe complications. Hence, the translational and angular accuracies are critical. However, traditional image-based surgical navigation la...

CIRUGÍA RECONSTRUCTIVA SISTEMA DE NAVEGACIÓN DE CÓDIGO ABIERTO CIRUGÍAS ALINEAMIENTO DE HUESOS TRACKEO DE MOVIMIENTO ANÁLISIS DE ERROR NAVEGACIÓN Purpose: During reconstructive surgery, knee and hip replacements, and orthognathic surgery, small misalignments in the pose of prosthesis and bones can lead to severe complications. Hence, the translational and angular accuracies are critical. However, traditional image-based surgical navigation lacks orientation data between structures, and imageless systems are unsuitable for cases of deformed anatomy. We introduce an open-source navigation system using a multiple registrations approach that can track instruments, implants, and bones to precisely guide the surgeon in emulating a preoperative plan. Methods: We derived the analytical error of our method and designed a set of phantom experiments to measure its precision and accuracy. Additionally, we trained two classification models to predict the system reliability from fiducial points and surface matching registration data. Finally, to demonstrate the procedure feasibility, we conducted a complete workflow for a real clinical case of a patient with fibrous dysplasia and anatomical misalignment of the right femur using plastic bones. Results: The system is able to track the dissociated fragments of the clinical case and averages alignment errors in the anatomical phantoms of 1.08 ± 0.68mm and 1.49 ± 1.19°. While the fiducial-points registration showed satisfactory results given enough points and covered volume, we acknowledge that the surface refinement step is mandatory when attempting surface matching registrations. Conclusion: We believe that our device could bring significant advantages for the personalized treatment of complex surgical cases and that its multi-registration attribute is convenient for intraoperative registration loosening cases. 2024-05-07T16:59:46Z 2024-05-07T16:59:46Z 2021 Artículo de publicación periódica https://ri.itba.edu.ar/handle/20.500.14769/4461 en application/pdf
