At burst vertebral fractures, magnetiс resonance imaging allows to assess the state of intervertebral discs, ligaments, presence of hematoma and thereby predict the course of spinal segment regeneration. To study the distribution of the hematoma and to establish the presence of other factors arising during a burst fracture of the vertebral body affecting the course of regeneration of the vertebral body, MRI diagnosis was performed in 42 patients with incomplete burst fracture (А3.1), incomplete explosive fracture with cleavage (A3.2), complete burst fracture (А3.3), a burst fracture with distraction (AB), a burst fracture with rotation (AC) according to the classification of F. Magerl et al. (1994). The results of the investigation allowed the following conclusions. Magnetic resonance imaging is an informative method of diagnosis of burst fractures of the spinal column and can predict the course of deformity development and regeneration processes of vertebral body. Only MRI can diagnose rupture of the ligament and disc, predict the course of residual deformation of the spinal column and choose the right method of treatment −− conservative or surgical. In the majority of cases burst fracture is accompanied by hemorrhage in the area of the anterior longitudinal ligament, of different sizes, allowing statement that in some patients regeneration of the vertebral body at burst fractures of type A occurs in the form of periosteal regeneration with formation of osseous adhesion along the hemorrhage through the intervertebral disc to the adjacent body.
