Statistical Shape Model of the Calcaneus Bone for Comprehensive Assessment of Three-Dimensional Morphology

Calcaneus is the most susceptible tarsal bone to fractures, presenting the most challenging treatment for associated tissue damage. Intra-articular calcaneal fractures present substantial challenges for patients and surgeons due to their association with both immediate and delayed complications. The purposes of this study were to establish a method for three dimensional morphological measurements of the normal calcaneus, we develop a statistical shape model (SSM) of the calcaneus that incorporates CT scans to enable a comprehensive assessment of its three-dimensional morphology. Though surface-based registration and point-wise correspondence analysis, the left and right calcaneus bones were compared with a variety of shape analysis. The compactness and parallel analysis test on the statistical shape model yielded 7 prominent shape modes of variations (MoVs), which accounted for approximately 89% of the total 3D variations in the population of shapes. Among these modes, two captured discriminating features from both the left and right calcaneus bones (p value < 0.05). Visual inspection confirmed that these two shape modes represented abnormalities in the anterior and anteromedial parts of the calcaneus, highlighting them as the primary bony risk factors in ankle injuries. In conclusion, our study utilizing a Statistical Shape Model (SSM) has identified significant shape variations (MoVs) of the calcaneus bone which correlate significantly with the left and right sides of the body. The results of our study also demonstrate the potential utility of the SSM as a tool for providing guidance in surgical planning and treatment of calcaneus pathologies.
