N2 - Distal radius fractures (DRF) are among the mostcommon fractures and treatment often involves surgicalreduction and internal fixation with a volar locking plate(VLP). Due to their high incidence, fracture treatmentsare extensively investigated – both with experimentsand finite element analyses (FEA). Still, the loadingconditions are often highly simplified. In experiments,load is typically applied uniaxially at the radiocarpaljoint (RCJ) using embedding materials or indenters ofarbitrary shape [1]. In FEA models, either embeddingmaterial is used or point loads are applied at the articularsurface [2]. Only rarely, carpal bones and articularcontact are accounted for [3]. However, the loaddistribution at the RCJ might be of high relevance forthe loading of the VLP system, as the distal screws arepositioned just below the articular surface. This studyinvestigates if the effort of implementing complexboundary conditions with articular contact is justified topredict VLP loading parameters accurately.
