“…Orthopedic surgeons recognize that combined injury to the ATFL and deltoid ligament (DL) can lead to a more complicated condition known as Rotational Ankle Instability (RAI) ( Valderrabano et al, 2007 ). Studies have shown that in cases of ATFL injury, there is a 40% likelihood of concurrent deltoid ligament injury ( Koh et al, 2023 ). The prevailing treatment for RAI in clinical practice focuses on repairing or reconstructing the lateral ATFL and calcaneofibular ligament (CFL).…”

BackgroundInjury to the lateral collateral ligament of the ankle may cause ankle instability and, when combined with deltoid ligament (DL) injury, may lead to a more complex situation known as rotational ankle instability (RAI). It is unclear how DL rupture interferes with the mechanical function of an ankle joint with RAI.PurposeTo study the influence of DL injury on the biomechanical function of the ankle joint.MethodsA comprehensive finite element model of an ankle joint, incorporating detailed ligaments, was developed from MRI scans of an adult female. A range of ligament injury scenarios were simulated in the ankle joint model, which was then subjected to a static standing load of 300 N and a 1.5 Nm internal and external rotation torque. The analysis focused on comparing the distribution and peak values of von Mises stress in the articular cartilages of both the tibia and talus and measuring the talus rotation angle and contact area of the talocrural joint.ResultsThe dimensions and location of insertion points of ligaments in the finite element ankle model were adopted from previous anatomical research and dissection studies. The anterior drawer distance in the finite element model was within 6.5% of the anatomical range, and the talus tilt angle was within 3% of anatomical results. During static standing, a combined rupture of the anterior talofibular ligament (ATFL) and anterior tibiotalar ligament (ATTL) generates new stress concentrations on the talus cartilage, which markedly increases the joint contact area and stress on the cartilage. During static standing with external rotation, the anterior talofibular ligament and anterior tibiotalar ligament ruptured the ankle’s rotational angle by 21.8% compared to an intact joint. In contrast, static standing with internal rotation led to a similar increase in stress and a nearly 2.5 times increase in the talus rotational angle.ConclusionInjury to the DL altered the stress distribution in the tibiotalar joint and increased the talus rotation angle when subjected to a rotational torque, which may increase the risk of RAI. When treating RAI, it is essential to address not only multi-band DL injuries but also single-band deep DL injuries, especially those affecting the ATTL.

BACKGROUND: Ankle injuries of various nature bruises, sprains, tears, dislocations and subluxations, and fractures account for 2030% of all musculoskeletal system injuries. The most common ankle injuries are a tear and sprain. The difficulty in treating fractures in this location is due to the need for accurate repositioning of the articular surface and stable fixation of fragments. The actual task is to train roentgenologists in the field. The inclusion of medical personnel in the educational process at all levels of training simulation courses aids in the reduction of errors, reduction of problems, and the improvement of the quality of medical treatment provided to the public. OBJECTIVE: This study aims to develop and create a simulator that simulates human bone structure and soft tissues and allows roentgenologists to get through training and instruction radiological examinations of an ankle joint and a foot. MATERIALS AND METHODS: The following stages of the simulators development have been completed: acquiring ankle bone samples, creating a mold for casting, and constructing the simulator. The results of computer and magnetic resonance imaging were used to construct bone samples, from which a computerized 3D model of the bones of the foot and ankle joint was obtained. Using additive technologies, anatomically correct reproductions of human foot and ankle bones were made. At the next stage, a three-dimensional digital model was developed, and a mold for casting the finished product was made. Bone samples collected in a single structure were placed inside the mold. Next, a step-by-step filling of the form with a soft gel-like material was performed. In this case, a self-vulcanizing silicone rubber composition is selected, which, after solidification, imitates human soft tissues. RESULTS: During the course of the study, a prototype medical simulator was created that models human bone structure and soft tissues and allows roentgenologists to practice performing ankle joint and foot roentgenography. CONCLUSION: Because of its high anatomical accuracy, ease of use, and mass production potential, the developed simulator can be widely employed in the teaching of roentgenologists.
