Calcaneal fractures are the most common fractures of the tarsal bones, representing 2% of all fractures and accounting for 60%–65% of all tarsal fractures. Although conventional radiography is the first choice for diagnosis of calcaneal fractures, it can not distinguish accurately intra-articular fractures from microfractures. Two-dimensional multiplanar reformation (MPR) of the CT allows accurate evaluation of fracture lines, dislocation and comminution, but it cannot provide a global depiction. The three-dimensional reconstruction techniques can compensate the lack of conventional radiography and MPR imaging: it can not only display three-dimensional form of the lesions, but also observe the fractures not displayed in cross-sectional images.
