Displaced intra-articular calcaneal fractures treated with Calcanail® and additional screw fixation of the thalamic surface through lateral subtalar arthroscopy

The treatment of displaced intra-articular calcaneal fractures is not standardized, as many surgeons prefer not to perform surgery, considering a high rate of cutaneous complications associated with the usual extensile lateral approach. The Calcanail® represents a percutaneous osteosynthesis device that is biomechanically more stable than multiple screws or locking plates. While it effectively restores the height and axis of the hindfoot, it appears to be less reliable in achieving articular reduction of the thalamic surface in cases of mixed fractures. Therefore, we developed a new technique suitable for comminuted mixed fractures, using the Calcanail® device with an arthroscopically guided closed reduction internal fixation of the thalamic surface.
