The aim of this study was to evaluate the biomechanical performance of the C-Nail\u00ae system and compare it with conventional plate fixation for the treatment of displaced intra-articular calcaneal fractures using finite element analysis. The geometry of a Sanders type-IIB fracture was constructed using the computer-aided design software Ansys SpaceClaim. The C-Nail\u00ae system (Medin, Nov\u00e9 Mesto n. Morave, Czech Republic) and the calcaneal locking plate (Auxein Inc., 35 Doral, Florida) and screws were designed according to the manufacturer specifications. Vertical loading of 350 N and 700 N were applied to the subtalar joint surfaces to simulate partial weight bearing and full weight bearing. Construct stiffness, total deformation, and von Mises stress were assessed. The maximum stress on the C-Nail\u00ae system was lower compared with the plate (110 MPa vs. 360 MPa). At the bone level the stress was found to have higher values in the case of the plate compared to the C-Nail\u00ae system. The study suggests that the C-Nail\u00ae system can provide sufficient stability, making it a viable option for the treatment of displaced intra-articular calcaneal fractures.<\/jats:p>","DOI":"10.3390\/jpm13040587","type":"journal-article","created":{"date-parts":[[2023,3,28]],"date-time":"2023-03-28T02:11:40Z","timestamp":1679969500000},"page":"587","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Biomechanical Comparison of Conventional Plate and the C-Nail\u00ae System for the Treatment of Displaced Intra-Articular Calcaneal Fractures: A Finite Element Analysis"],"prefix":"10.3390","volume":"13","author":[{"given":"Roxana Maria","family":"P\u00eenzaru","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Surgical Science (II), Faculty of Medicine, \u201cGrigore T.
