Rekonstruktion fehlverheilter Calcaneusfrakturen

The hindfoot represents an anatomical and functional link between the lower leg (vertical and rigid strut) and the mid- and forefoot (horizontal and flexible). The topographic position of the heel is critical considering the static and dynamic stability of the whole leg. In case of a fracture of the calcaneus, displacement of the heel within the frontal (coronal) plane is particularly relevant. If the fracture involves the subtalar joint implementing posttraumatic arthritis and functional impairment, corrective re-orientation of the heel goes together with subtalar joint fusion which is best achieved by using an autologous tricortical bone block. If significant malunion is caused by a less frequent extra-articular fracture, re-orientation can be achieved by a calcaneus osteotomy including translation and angulation of the calcaneal tuberosity.
