Background: Pelvic ramus fractures in older patients are associated with substantial morbidity and mortality. There is a paucity of literature on fractures of the pelvis in this age group. The purpose of this study was to report mortality rates following such injuries. In addition, we aimed to describe and quantify the important resultant morbidity in this vulnerable population. Methods: We performed a retrospective chart review of all low-energy pelvic ramus fractures in patients more than age 60 years that occurred between January 2000 and December 2005. Data on survival, hospital length of stay, ambulatory status and place of residence were recorded. For comparison, we calculated the mortality rate for a surrogate age-and sex-matched group using Statistics Canada survival data for use as an uninjured control group. Results: We identi ed 43 patients (32 women [74%]; mean age 79.4 yr) with isolated low-energy pelvic ramus fractures over the study period. The 1-and 5-year mortality rates were 16.3% (95% con dence interval [CI] 7.8%-30.3%) and 58.1% (95% CI 43.3%-71.6%), respectively, both signi cantly higher than the point estimates for the control group (6.6% and 31.3%, respectively). Following injury, 14/39 patients (36%) permanently required increased ambulatory aids, and 8 (20%) required a permanent increase in everyday level of care. Conclusion: The results suggest that there may be increased mortality and morbidity following low-energy pattern pelvic ramus fractures in an older population compared to age-and sex-matched uninjured control subjects. Contexte : Les fractures du bassin chez les personnes âgées sont associées à une morbidité et une mortalité substantielles. La littérature sur les fractures du bassin dans ce groupe d'âge est peu abondante. Le but de cette étude était donc de faire état des taux de mortalité suite à de telles blessures. Nous avons aussi voulu décrire et quanti er l'importante morbidité qui en résulte chez cette population vulnérable.
