Clinical relevance between anatomic features of sustentaculum tali and intra-articular calcaneal fractures / 国际外科学杂志

ABSTRACT

The calcaneus is the most commonly fractured tarsal bone,calcaneal fracture comprises 2％ of all fractures,the primary mechanism of injury involves a high energy axial load.To get a better outcome,the literature review recommends the use of Open Reduction and Internal Fixation (ORIF) for this kind of injury.Sustentaculum tali is a triangular projection from the medial surface of the calcaneus,it possesses strong trabecular structure and thick cortex,and it's thought to remain tightly bound to the talus by ligaments and muscle tendons nearby,that's why it's often used as a constant fragment to which other fracture fragments are reduced to restore congruity of the subtalar joint.Hence,it's important to understand the anatomic features of sustentaculum tali.In this article,we describes the anatomic measurements of the sustentaculum tali including the size,angle and soft tissue nearby,and described the correlation between these anatomic features and intra-articular calcaneal fractures.We are hoping that we can provide theoretical reference to the clinical treatment of calcaneal fractures.
