Abstract

Displaced intra-articular calcaneal fractures are difficult to treat because of complex anatomy and high soft tissue complications. Various surgical approaches have been introduced to solve these problems, but the treatment remains complex. Recently, clinically and radiographically superior results were reported using a subtalar arthroscopy in reducing the posterior facet in both percutaneous and open approaches. In the percutaneous approach, the arthroscopically assistant percutaneous approach must be selected carefully for mild-tomoderately displaced fractures because of the limited view. In the open approach, there is little evidence of the utility of subtalar arthroscopy. Therefore, intraoperative arthroscopy should always be used in conjunction with fluoroscopy to achieve reduction and assess the internal fixation placement.
