Preoperative imaging of the left foot. The upper part revealed a multifragmentary fracture of the calcaneus, with a Boehler's angle of 5 degrees. The CT scan permitted to classify the fracture as a Sanders type IIBC.

The X-ray of the foot showed an intra-articular calcaneal fracture with a Boehler's angle of 5 degrees, as we can see in Figure 1. The CT scan (Figure 1) revealed a multifragmentary fracture of the calcaneus, with a depression of the articular surface.
Operative procedure steps: (a) distractor use, (b) balloon reduction, (c) fluoroscopic control, and (d) skin incisions at the end of surgery.

The main steps are represented in Figure 2.
Postoperative imaging, showing a good reduction of the subtalar joint, with a Boehler's angle of 24 degrees, satisfying axis of the calcaneus, and no leakage of cement.

On the upper part, postoperative radiographs showed a Boehler"s angle from 33 degrees. On the lower part, postoperative CT scan showed satisfying alignment of the bone fragments, with presence of a discrete diastasis at the level of the posterior subtalar fracture, but without irregularity of the articular surface.
