Biomechanical Comparison of Conventional Plate and the C-Nail System for the Treatment of Displaced Intra-Articular Calcaneal Fractures: A Finite Element Analysis.

The C-Nail system is a novel intramedullary fixation method for displaced intra-articular calcaneal fractures. The aim of this study was to evaluate the biomechanical performance of the C-Nail 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.
