Abstract

Objectives: To describe the anatomical morphology of the calcaneus and subtalar joint using three-dimensional computed tomography (3D CT) reconstruction in Vietnamese adults. Methods: A descriptive cross-sectional, uncontrolled study was conducted on 139 normal 3D CT reconstructions of the calcaneus from adult subjects, with a mean age of 39.50 ± 12.95 years at Military Hospital 175 from January 2022 to June 2025. 3D calcaneal models were segmented from ankle-foot CT datasets to evaluate the morphology of the subtalar articular facets and to measure calcaneal anatomical parameters, including Böhler’s and Gissane’s angle. Results: Type I subtalar articular facet configuration was the most common (46.04%), followed by type IV (25.90%), type III (17.27%), and type II (10.79%). No type V configuration was observed. All measured calcaneal anatomical dimensions were larger in males than in females. The mean Böhler’s angle and Gissane’s angle were 32.39° ± 5.39° and 124.40° ± 9.75°, respectively. Conclusion: 3D CT reconstruction is a valuable tool for the anatomical study of the calcaneus and the subtalar joint. The morphology and dimensions of the calcaneus in Vietnamese adults are comparable to those reported in other Asian populations, but differ from those described in European populations.
