Abstract

Purpose: Pelvic fracture fixation is a challenging procedure that commonly relies on 2D fluoroscopic guidance to place guidewires within complex bone corridors. Prior work reported on a video-on-drill navigation system for guidewire insertion as a potential solution. Here, we assess performance across a range of hardware components to help guide the design of future system prototypes with respect to clinical requirements. Methods: The video-on-drill system uses a camera rigidly mounted on the drill and multimodality fiducial markers (optical and radio-opaque) to provide real-time trajectory visualization. This work reports on the selection of a new camera+lens configuration. Configurations were assessed across two cameras (referred to as the ArduCam and ELP) and five lens options (A45-A90). Clinical requirements were specified by an orthopaedic-surgeon in terms of the nominal drill operating distance (𝐷) and operating area (𝐴). Performance was evaluated in terms of the accuracy of fiducial marker pose estimation (δ_𝐷), and the field of view (FOV). Results: At matched FOV, the accuracy for the ELP camera was significantly better (p < 0.01) with median δ_𝐷 of 1.26 mm (1.1 mm IQR) compared to the ArduCam [median δ_𝐷 of 1.85 mm (2.0 mm IQR)]. The accuracy of the A45 and A55 lens was found to be suitable (δ_𝐷 < 2 mm) while providing sufficient FOV at nominal drill operating conditions. Conclusion: With respect to application requirements, the camera+lens combination (ELP+Ardu55) was identified to provide the best performance, serving as an important precursor to future design iterations of the video-on-drill system.
