[en] Thirty-eight patients with fractured vertebrae were involved in our study. Patients were evaluated by standard plain radiographs of the spine, myelographies and post-myelographic computed tomographies of the damaged part of the spine. The aim of the study was to give an answer to the question if there is difference between frequency of the appearance of spinal haematoma in patients with fractured vertebral bodies and in patients with fractured vertebral arches. For that reason all patients were divided into two groups. Trauma of the spine was followed by spinal haematoma in the first group of the patients, whereas in the second group of patients spinal haematoma was not evidenced. The number of the fractured vertebral bodies and fractured vertebral arches in both groups of the patients were determined. Differences between these numbers were tested by chi square test. We concluded that fractures of the vertebral bodies and of the vertebral arches are followed by spinal haematoma in the same degree. (authors)
