Observation and clinical significance of calcaneus of human

Objective To study the anatomical characteristics of calcaneus of human to provide the anatomical basis for the surgical treatment of calcaneus fracture. Method The anatomical modality of sixty male adults’calcaneus was observed with gross anatomical method. Results Calcaneus＇s length, width and height are （71.5±4.2）mm, （41.4±2.4） mm and （42.3±2.8）mm respectively. Calcaneus＇s forepart, calcaneal sulcus and posterior＇s width are （24.6±2.1）mm, （32.1±2.6）mm and （26.9±2.1）mm respectively. Sustentaculum tali＇s length, width and height are （23.2±1.6）mm, （13.5±1.3） m and （10.9±11）mm respectively. Sustentaculum tali and calcaneus level＇s separation angle is （50±3）°, the separation angle between posterior articular facet to the calcaneal sulcus and the posterior articular facet to the calcaneal protrusion （Gissane＇s angle） is （123.5±8.7）°. The separation angle（Bohler＇s angle） between posterior articular＇s superior margin to the cuboid joint surface＇s anterior margin and to the calcaneal tubercle＇s superior margin is （34.6±4.1）°. Conclusion The values of the normal man calcaneus of the present study can provide the anatomical basis fo the surgical treatment of calcaneus fracture.
