After the clinical and radiographic evaluation (simple radiographs, CT and MRI if necessary) of the patients the fracture will be classified according to the classification Magerl et al., and the therapeutic planning defined. Fractures with surgical indication by means of the posterior approach will be selected for the study and the randomization process performed individually for each type of fracture (A, B and C) according to the Magerl classification. Patients will be randomized and assigned to two groups: A - conventional open surgery and B - minimally invasive percutaneous surgery.
