The purpose of this study is to evaluate the correlation between sacral fractures and neurological deficits as complications. From November 2002 to February 2005, 12 patients (15 fractures) were found to have sacral fractures without other spinal injuries or brain injuries and were evaluated by plain CT scans immediately after trauma. This group included 6 males and 6 females, whose age ranged from 17 to 67 years with mean of 39.9±17.4. All patients were classified according to AO (Arbeitsgemeinschaft für Osteosynthesefragen) classification (pelvic ring fracture) and Denis's classification. Displacements of sacral fractures were evaluated by plain CT scans for all patients. We defined displacements using the key slice in CT scans that included the first foramen in the sacrum. Five cases, including 2 with bi-lateral sacral fractures, were complicated with neurological deficits. There was one case with a neurological deficit of 7 Type B fractures (14%) and 4 cases with neurological deficits of 5 Type C fractures (80%) in the AO classification. There were 6 fractures with neurological deficits of 12 Zone II fractures (50%) and one fracture with neurological deficits of one Zone III fractures (100%) in Denis's classification. There was a significant correlation between the extent in the displacement of the sacral fractures and neurological deficits. For more than 3mm displacements in the medial or lateral or anterior directions, neurological deficits increased significantly. In emergency medicine, it is difficult to evaluate the neurological findings of patients with impaired consciousness. Our evaluation using CT scan is valuable as a predictor of neurological deficits and for an optimal reduction in sacral fractures in patients with in impaired consciousness.
