[Intra-articular calcaneus fracture. Classification in CT as a prerequisite for therapeutic decision and quantitative comparison].
Whether conservative or operative management is selected for intra-articular fractures of the os calcis depends on subjective factors and on the surgeon's experience. There is no classification available that allows ranking of such fractures according to the extent of destruction and the degree of dislocation at the same time. CT scans of 44 calcaneal fractures have been used to elaborate a new classification system for calcaneal surfaces. According to the involvement of joint surfaces, especially of the posterior facet, the degree of dislocation and the number of fragments of the posterior facet, six classes are defined. Within each class of fracture, the formation of "steps" in the posterior facet, widening of the heel, loss of height and deviation of axes are quantified. The new classification provides an instrument for use in the evaluation of joint destruction and dislocation. It helps to provide an objective basis for decisions between functional treatment and open reduction with internal fixation and for prospective analysis of fracture treatment.
