Bone fracture analysis for calcaneus

Abstract

Calcaneus fractures are injuries caused by sprains, fall down, falls from high places, or traffic accidents and characterized by the tendency for pain to remain. One of the causes of this pain is poor reduction. In the Essex-Lopresti classification, which is one of the calcaneus fracture classifications, the fracture patterns of calcaneus fractures are roughly divided into two types, tongue type and joint depression type, and it has been suggested that the fracture patterns differ depending on the mechanical condition at the time of injury. Thus, it is important to perform accurate reduction by clarifying the relationships between the difference in mechanical condition at the time of injury and the fracture pattern, which is thought to lead to early healing. Therefore, in this study, it was investigated whether the fracture pattern as seen in the calcaneus fracture classification can be reproduced by considering bone fracture in the finite element analysis for the calcaneus. Furthermore, we investigated the usefulness of this analysis method for clarifying the relationships between the difference in mechanical condition at the time of injury and the fracture pattern. As a result, we indicated that the fracture pattern corresponding to calcaneus fracture classification could be reproduced by bone fracture analysis. In addition, it was suggested that this analysis method is useful for clarifying the relationships between the difference in mechanical condition at the time of injury and the fracture pattern, since the results based on this analysis was consistent with the contents described in the Essex-Lopresti classification.
