[The CT classification of intra-articular calcaneus fractures]

93 patients with 102 intraarticular calcaneus fractures (ICF) were examined by CT from 1986 to 1992. The images were evaluated with the use of a modified classification based on the number of fractured heel bone facets (2 facets in 4.8%, 3 facets in 53.9%, 4 facets in 32.3%, comminution in 8.8% of the fractures), the involvement of the calcaneus-cuboid joint (60.8%) and the fracture mechanism (tongue-type in 28.4%, joint depression in 62.7%) with the weight-bearing calcaneal compartments taken into special consideration. In that way, each intraarticular calcaneus fracture could be scored, enabling a fast diagnosis comprising factors relevant for the therapy and prognosis.
