Spine fractures in falling accidents: analysis of multidetector CT findings

Abstract

The purpose of the present study was to assess incidence, fracture type, and location of spine fractures due to falls. All emergency room CT requests during a time period of 26 months were reviewed retrospectively. Patients who had fallen or jumped and were initially examined with multidetector CT (MDCT) were included. The MDCT studies were evaluated by two radiologists for trauma location, fracture type, and multiple level involvement. A total of 237 patients (184 males, 53 female, age range 16-86 years, mean age 42 years) met the inclusion criteria. A total of 203 vertebral fractures were seen in 127 patients. Burst fracture (n=78) was the most frequent type of trauma, usually located in the thoracolumbar junction (50%). Also, compression fracture (n=52) was most common in the thoracolumbar junction (39%). Posterior column fracture (n=52) was most frequently detected in the cervical spine (40%). Multiple-level spine fractures were seen in 41 (32%) of the injured patients, of which 12 (29%) had fractures at noncontinuous levels. With increasing height the overall incidence of fractures increased, and burst fractures and multiple level spine fractures became more frequent. Age had no effect on fracture type or location. Spine fractures due to falls are common. Burst fracture is the most common fracture type and most frequently seen in the thoracolumbar junction. Multiple-level fractures were seen in 32% of the cases, of which 29% were seen at noncontinuous levels. Serious spine fractures are seen in all falling height and age groups.
