[Classification of posterior malleolar fractures in ankle fractures].

The study presents an overview of the most common radiography and CT-based classifications of posterior malleolar fractures in ankle fracture-dislocations. Their analysis has shown that posterior malleolar fractures largely vary in size and shape. Evaluation of fractures by plain radiographs is inadequate. A detailed assessment of the fragment shape and course of fracture lines requires CT examination in all three projections, followed by 3D CT reconstructions.Key words: ankle fracture - dislocations trimalleolar fractures posterior malleolar fractures classification.
