Inter-rater variability of three-dimensional fracture reduction planning according to the educational background

Abstract Background Computer-assisted three-dimensional (3D) planning is increasingly delegated to biomedical engineers. So far, the described fracture reduction approaches rely strongly on performance of users. The goal our study was analyze influence two different professional backgrounds (technical and medical) skill levels regarding reliability proposed method. Finally, a new fragment displacement measurement method introduced due lack consistent methods in literature. Methods 3D bone models 20 distal radius fractures were presented nine raters with educational (medical technical) various experience operation (0 10 years) clinical (1.5 24 years). Each rater asked perform software. Results No difference demonstrated accuracy rotational ( p = 1.000) translational 0.263) misalignment fragments between engineers senior orthopedic residents. However, significantly more accurate performed these groups compared junior residents less no < 0.05). Conclusion Experience are relevant factors plan an intra-articular radius. observed background vs. Therefore, results support further development computer-assisted surgery by Additionally, measure proves be feasible reliable Level Evidence Diagnostic II
