Abstract
BackgroundCalcaneal fractures are associated with numerous complications and a poor prognosis with significant long-term quality-of-life issues, regardless of treatment. Therefore, in-depth research into the underlying mechanism of calcaneal fracture is still of great interest, with the goal of improving treatment for patients suffering from this condition. This study aimed to investigate the relationship between the distribution of calcaneal fracture lines and their determinants, especially those related to the internal structure of the calcaneus. This goal was achieved by fracture maps created by copying and stacking fracture lines as viewed from six surfaces of the calcaneus.MethodsA total of 210 consecutive patients with 226 calcaneal fractures were retrospectively analyzed. Fracture lines were copied from a reduced 3D calcaneal fracture model and stacked on calcaneal templates to generate fracture maps. The stacked images of six calcaneus surfaces were also converted into spectrograms with MATLAB to highlight the fracture frequency at specific locations.ResultsThere were four concentrated bands of fracture lines and two fracture hot spots on the superior surface. Three dense bands of fractures were observed on the medial surface, and four fracture bands were observed lateral to the calcaneus. Vertical fracture lines dominated the anterior calcaneal fracture map. On the posterior surface, the fracture lines appeared to be centered superiorly. All fracture locations coincided with the interfaces between the trabecular groups.ConclusionsThe fracture maps showed fracture patterns and recurrent fracture zones on all calcaneal surfaces. The shape of the talus and calcaneus and the architecture within the calcaneus, especially the arrangement of the trabeculae, are essential factors for calcaneal fractures.
Highlights
Calcaneal fractures are associated with numerous complications and a poor prognosis with significant long-term quality-of-life issues, regardless of treatment
The images were imported into Adobe Photoshop CC 2018 (Adobe, San Jose, CA, USA), and their transparency was adjusted to 50%; they were used as fracture mapping templates
We verified that the shape of the talus and calcaneus, especially the lateral process of talus, plays a vital role in the initiation of fracture

This goal was achieved by fracture maps created by copying and stacking fracture lines as viewed from six surfaces of the calcaneus. In-depth research on the mechanism of calcaneal fracture is still of great interest for improving treatments. The characteristics of calcaneal fracture fragments and lines are mainly determined by three aspects: the shapes and positions of the talus and calcaneus, the inner
