Background: Multiple vertebral fractures (MVF) are the result of high-energy trauma. These can be contiguous (CMVF) when there is a fracture of two or more vertebral bodies in an adjacent way and non-contiguous (NCMVF) when there are lesions of various levels separated by at least one vertebra without injury. Objective: To evaluate clinical features and kinematics, establish distribution, evaluate association with extra-vertebral injuries, detail complications. Materials and Methods: A multicenter, prospective, and observational study. Patients with MVF. Results: Sixty-six patients presented 196 vertebral lesions, without neurological deficit in 55; 26 were women and 40 were men, with an average age of 39 years old. Kinematics: 32 car accidents, 27 falls from height, 5 direct traumas and 2 sports traumas. Topography: 2 C0-C3, 4 C3-C7, 8 C7TT1, 61 T1-T10, 91 T10-L2, 28 L2-L5 and 1 sacrum. Combination: 21 thoracolumbar-thoracolumbar and 8 thoracic-thoracic. There were 32 contiguous injuries, 19 non-contiguous injuries, and 15 mixed-pattern injuries. Twenty-six patients presented 47 extra-verterbral injuries (20 multiple trauma, 12 thoracic trauma). 36 patients received non-surgical treatment and 30 patients underwent surgery. Conclusion: The presence of MVF in spinal cord trauma is frequent, most do not show neurological involvement and are consequences of motor vehicle accidents. The most affected sector was between T2 to L5, the most frequent combination was thoracolumbar-thoracolumbar, followed by thoracic-thoracic; the most frequent were extra-vertebral injuries, mainly head and chest trauma. Complications: one patient had increased kyphosis; one, surgical site infection; and one patient died.
