Abstract
Different technologies have been used for computer assisted orthopaedic surgery for acquisition of surfaces and motions, but the most efficient are optical and mechanical[2]. In this study we compared two specific systems of these categories: FlashPointTM 5000 (Image Guided Technologies, USA) and FAROArmTM (FARO Technologies, USA). FARO Arm showed an intrinsic uncertainty of 0.1mm overcoming FlashPoint (0.2mm). However their use in noisy conditions resulted in similar application-uncertainty. FARO Arm can track motion at 31Hz while FlashPoint at 17Hz, therefore FlashPoint spatial resolution may be critical during fast movements. In simulated medical applications FARO Arm showed some difficulties (i) when used for passive motion with negligible forces, because the surgeon has to compensate its weight and (ii) during sample trajectory, because it has isolated singularities within its workspace. FlashPoint was affected by reflected light and required complete visibility during tracking of large trajectories. However its use in in-vivo conditions is more promising than FARO-Arm’s.
