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

Abstract For femoral fractures of the trochanteric region in children and adolescents, only two mechanisms have been identified to cause a fracture of the proximal femur: high-energy trauma or predisposing bone pathologies with inadequate trauma (e.g., simple fall, movement). We identified 20 patients between 1993 and 2018 with a trochanteric fracture under the age of 18 (12 males; 8 females; mean age, 12 years; range, 4–17 years) who were treated operatively at our department. The mean follow-up of all patients was 50.06 months. All 20 patients were treated operatively. Complications occurred after a mean time of 6.27 months (range, 0.47 to 12.07 months) in two patients. Harris Hip Score was evaluated in all patients with a mean score of 94.16 (range 11 to 100). Eighty-five percent of the patients reached an excellent clinical outcome after treatment. Trochanteric femoral fractures in children and adolescents are very rare accounting for only 1% of all trochanteric fractures. Excellent long-term results can be achieved with an adequate fracture reduction. Conclusion: Physicians treating pediatric trauma have to be aware of other predisponding diseases when low-energy trauma leads to a trochanteric fracture as in this study, 50% of the trochanteric fractures were associated with bone pathologies. What is Known:• Trochanteric femoral fractures in children and adolescents are very rare• In all patients with trochanteric femoral fractures, malignancies have to be ruled outWhat is New:• Awareness of an underlying bone pathology in a high number of cases• Awareness for necessity of a good fracture reduction leading to highly satisfactory results
