This research presents the results of a structural mechanical analysis performed on an implant designed for the rehabilitation of type B ankle fractures, aimed at its application for patients undergoing therapeutic rehabilitation. The study focuses on a 40-year-old male, weighing 90 kg and standing 1.80 m tall. The bone model, which features a distal fibular fracture, was created using a high-resolution, non-contrast computed tomography scan with a resolution of 0.625 mm. The DICOM images were meticulously segmented with ScanIP® software to define the region of interest. The modeling and assembly of the implant were carried out using SpaceClaim® software. The structural mechanical analysis of the implant was conducted using the finite element method, implemented in the ANSYS 2021 R1® Academic program. This analysis considered the effects of muscle forces, bone mechanical properties, and the load experienced during the mid-stance phase of walking, which is equivalent to three times the subject's body weight, or 2648.7 N. Additionally, various experimental load application tests were performed on the implant. For this purpose, 3D printing in PLA was utilized to create models of the tibia, fibula, and talus, allowing for the rigid fixation of the implant. An incremental load was systematically applied to the models, ranging from 882.9 N to 2648.7 N. This methodology enabled the determination of the implant's strain using the GOM Correlate® software. The results indicated a significant reduction in stresses in the regions proximal to the fracture following implant insertion, thereby substantially aiding in the optimal rehabilitation of the patient.
