“…One hundred two-foot ligaments were modeled using rod units that can only be stretched but not compressed based on the anatomical information on the digital anatomical platform and the human atlas. These ligaments were manually positioned and added to the model according to the relevant anatomical landmarks, similar to previous studies [ 10 – 13 ]. Sixty bone models, 37 cartilage models, and 102 ligament models were obtained.…”

“…while we set the soft tissues as nonlinear materials to improve the reliability and accuracy of the experiments to simulate a more realistic quiet tissue state when this volunteer stood, and the floor material was manufactured as a wooden flat plate with a large Young’s modulus wooden flat plate to simulate the ground. The material properties of each component were obtained from the literature [ 13 , 18 , 19 ] (Table 1 lists the material properties of each element).…”

Background The purpose of this study was to evaluate the effect of varying the different correction angles of hindfoot osteotomy orthosis on the biomechanical changes of the adjacent joints after triple arthrodesis in adult patients with stiff clubfoot to determine the optimal hindfoot correction angle and provide a biomechanical basis for the correction of hindfoot deformity in patients with stiff clubfoot. Methods A 26-year-old male patient with a stiff left clubfoot was selected for the study, and his ankle and foot were scanned using dual-source computed tomography. A three-dimensional finite element model of the ankle was established, and after the validity of the model was verified by plantar pressure experiments, triple arthrodesis was simulated to analyze the biomechanical changes of the adjacent joints under the same load with “3°” of posterior varus, “0°” of a neutral position and “3°, 6°, 9°” of valgus as the correction angles. Results The peak plantar pressure calculated by the finite element model of the clubfoot was in good agreement with the actual plantar pressure measurements, with an error of less than 1%. In triple arthrodesis, the peak von Mises stress in the adjacent articular cartilage was significantly different and less than the preoperative stress when the corrected angle of the hindfoot was valgus “6°”. In comparison, the peak von Mises stress in the adjacent articular cartilage was not significantly different in varus “3°”, neutral “0°”, valgus “3°” and valgus “9°” compared with the preoperative stress. Conclusion The results of this study showed that different angles of hindfoot correction in triple arthrodesis did not increase the peak von Mises stress in the adjacent joints, which may not lead to the development of arthritis in the adjacent joint, and a hindfoot correction angle of “6°” of valgus significantly reduced the peak von Mises stress in the adjacent joints after triple arthrodesis.

“…Два висновки з його роботи добре співвідносяться з нашими результатами: найбільших стресових навантажень зазнає периталарна зона; чим більшу міцність мають капсула та зв'язки, тим менших навантажень зазнає кістяк стопи. Моделювання стресових навантажень у нормі, при ПС та клишоногості показало, що в будь-яких умовах однією з найбільш навантажуваних ділянок є периталарна зона [21].…”

Summary. The flatfoot remains a poorly defined clinical entity. Objective: to study the movements that occur in the foot under a single-support load on a two-segment model of the normal foot and flatfoot under different mechanical properties of the capsular-ligamentous complex acetabulum pedis. Materials and Methods. A two-segment model of the foot was developed, which consisted of anatomical hindfoot and forefoot. The connection between them was represented by a complex consisting of lig. calcaneonaviculare and the tendon of m. tibialis posterior. A decrease in the mechanical strength of the complex was represented by three types of tendon tissue degeneration according to Z.S. Rosenberg et al.: 0% – the norm, 25% – type І, 50% – type ІІ, and 75% – type ІІІ. The 3D finite element model was created using real foot skeletons from 12 patients with acquired flatfoot, obtained from 3D reconstructions with CT. The model was loaded with a force of 750 N from the plateau of the tibia in the direction of the ground surface. The adequacy of the model was assessed by examining the dependence of the simulation results with the values of the talo-navicular uncovered angle of the same patients. Results. The mutual movement of the segments forming the foot model progressively increased with a decrease in the strength of the capsular-ligamentous complex from 4.18 mm in the norm to 8.36 mm in type III degenerative changes. The linear nature of the dependence of total displacements on the decrease in the mechanical strength of the capsular-ligamentous complex is confirmed by the assessment of the adequacy of the model. Conclusions. The decrease in the mechanical strength of the capsular-ligamentous complex acetabulum pedis under a single-bearing load causes the mutual movement of segments of the model twice as large compared to the norm; the calculated dependence of movement/decrease in strength is linear.

“…It has been commonly used to assess the biomechanics and stability of individual implants and to understand the mechanism of adverse trauma events [ 12 – 15 ]. Moreover, FEA has been used to analyze the internal pressure distribution of the foot in disorders such as flatfoot, clubfoot, and Lisfranc joint injuries [ 16 ].…”

Background Calcaneal fractures are the most common tarsal bone fractures, and account for 75% of intra-articular fractures. The purpose of this study was to compare the biomechanical stability of the anterior process locking plate combined with the percutaneous cannulated screw fixation (screw group) versus the anterior process locking plate fixation alone (plate group) for the treatment of Sanders type II calcaneal fractures using finite element analysis to provide a theoretical basis for clinical work. Material/Methods We established a 3D model of Sanders type II calcaneal fracture; assigned material properties to the internal fixation systems; applied loads; set up analysis criteria; analyzed the displacement of the fracture, relative displacement, stress state of bone tissue, and internal fixation; and compared mechanical stability. Results For Sanders type II A, II B, and II C calcaneal fractures, the degree of displacement and relative displacement of the fracture in the screw group was less than that of the plate group. For all subtypes of Sanders type II calcaneal fractures, the screw group had better mechanical stability than the plate group. Conclusions Both fixation methods (screw and plate group) were within a reasonable range for restoring the levelling effect of the joint surface and maintaining the strength of fixation, and both had good mechanical stability. Finite element analysis is a relatively reliable method, and biomechanics and clinical studies must further verify the experimental results.
