Abstract
The calcaneus is the most common tarsal bone to be fractured with an overall incidence of approximately 2% of all fractures. The calcaneus has a compiex three dimensional anatomy. It articulates with the talus superiorly through three articular facets; the posterior, middle and anterior facet. The posterior facet is the largest and the most important. The calcaneus also articulates with the cuboid anteriorly. It is formed largely of cancellous bone with a thin shell of cortical bone. Fractures of the calcaneus are classified according’ to sanders br> (75%) and extraarticular (25%) fractures. The management of intraarticular calcaneal fractures and their associated soft tissue injuries are challenging tasks for the surgeon. Open reduction and stable internal fixation with a lateral plate without joint transfixation has been established as a standard therapy for displaced intraarticular calcaneal fractures, with good to excellent results in most cases. Anatomical reduction of joint congruity and the overall shape of the calcaneus are important prognostic factors. The quality of joint reduction should be reliably proven intraoperatively either with Broden’s views, high resolution fluoroscopy or open subtalar arthroscopy.
