[Classification and surgical indications in spinal injuries].

A simple and precise classification of vertebral injuries is the key to correct treatment, depending on the differentiation of temporary or permanent instability. This aim is met by a classification presented by Magerl, Harms, Gertzbein et al. It is based on three main types according to the pathomechanics consisting of several subgroups with morphological aspects. In the neurological field, indications for surgical treatment are absolute after a free interval or rapid rising of the level of lesion. In vertebral injuries operative indications are found in possibly permanent instabilities or kyphotic deformities. Some indications depend on the patient himself, especially age and psychosis.
