Background This study aimed to evaluate Sanders type 2 calcaneal fractures in 197 patients from a single center using the 3D (three-dimensional) CT (computed tomography) mapping method. Material/Methods A consecutive series of 197 Sanders type 2 joint depression calcaneal fractures was used. The segment and split functions were used to create each calcaneal fragment using Mimics Research 20.0 software. The fracture fragments were reduced in 3-matic Research 12.0 software. In the E-3D Medical 18.01 software, after superimposing the fractured calcaneus entity with the calcaneus template, we drew the fracture line on the template. Finally, the heatmap was obtained by fracture statistical analysis function. Simultaneously, the distribution of the fracture lines in the anterior part of the calcaneus (APC) and middle talar joint was recorded. Results There were 109 cases of Sanders type 2A, 46 cases of Sanders type 2B, and 42 cases of Sanders type 2C. Based on the data, we drew the characteristic fracture map of type 2A 2B and 2C. This study found that the most common types of Sanders type 2A in APC and middle talar articular surface are type AC and type AD. In Sanders type 2B, the most common type is type AC, and in Sanders type 2C it is type ACD. Conclusions The findings from this study showed that 3D CT imaging and reconstruction of the calcaneus was a useful diagnostic method to evaluate and classify joint depression calcaneal fractures. The calcaneal fracture map can be used to guide surgical planning and optimize the design of internal fixation.

Ultrasound waves due to their inherent small wavelength can be used in diagnosis or evaluation of tissue. Ultrasound simulations can be useful to investigate and analyze different properties at different sites especially when there is no volumetric data available. In the proposed paper, simulation of ultrasound in a 2-D bone model and hardware implementation has been presented. Due to complex structures of bone, a simple linear model consisting of both cortical and cancellous bone has been proposed. In the simulation, a broadband emitter with center frequency of 1 Megahertz is used along with an array of receivers to capture the signal. An attempt has been made to calculate bone density parameters in-vivo for human feet, and finally display the computed parameters onto a LCD using Arduino Uno Board. An algorithm involving fourier transforms was used to calculate Broadband Ultrasound Attenuation (BUA) and Speed of Sound (SoS) in Matrix Laboratory (MATLAB).

“…The shape of the calcaneus and talus determines the formation of the initial fracture site and the second primary fracture. Previous research has explained the role of the wedge-like anterolateral process of the talus and the thick bony strut at the angle of Gissane in producing a typical original lesion [8][9][10]. Axial loading then drives the anterolateral process into the angle of Gissane in an ax-like manner, and the second primary fracture line appears, running medially and laterally.…”

Background Calcaneal 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. Methods A 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. Results There 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. Conclusions The 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.
