The profile of spinal injuries in the elderly population

Abstract

This retrospective cross-sectional study sought to: describe the profile of the elderly population who suffered spinal injury (SI) between 2005 and 2010 in Porto Alegre (RS), Brazil; compare the trauma mechanism and type of SI prevalence in both sexes; and compare the trauma mechanism in the sample's age groups. To this end, medical records were reviewed for the following data: age, sex, main mechanisms of injury and spinal levels affected. Out of 1.320 records analyzed, 370 belonged to elderly subjects, 58.6% women (73.07±8.52 years) and 41.4% men (69.4±7.5 years). The most prevalent SI mechanisms were falls from own height (37.7%), height (24.3%) and unspecified (20.1%). The most affected vertebral levels were L1 (30.0%), T12 (16.2%) and L2 (11.9%). Only 26 (7%) individuals who had SI suffered a spinal cord lesion, with a higher prevalence of incomplete lesion (82.6%). No significant association was detected between the occurrence of SI and its type or sex. In the time and region investigated, the SI profile in the elderly can be described as: women over 70, who suffered a fall from their own height, injuring mainly the lumbar region. Elderly men and women were equally affected by SI without spinal cord lesion. Falls from height predominated in those aged 60-69, whereas falls from own height were commonest among those aged 70 and over.
