title: High-energy proximal femur fractures in geriatric patients: a retrospective analysis of short-term complications and in-hospital mortality in 32 consecutive patients.
abstract: BACKGROUND
  There is limited information in the literature on the outcomes and complications in elderly patients who sustain high-energy hip fractures. As the population ages, the incidence of high-energy geriatric hip fractures is expected to increase. The purpose of this study was to analyze the outcomes and complications in patients aged 65 years or older, who sustained a high-energy proximal femur fracture.
  
  
  METHODS
  Retrospective review of a prospective trauma database from January 2000 to April 2011 at a single US academic level-1 trauma center. Inclusion criteria consisted of all patients of age 65 years or older, who sustained a proximal femur fracture related to a high-energy trauma mechanism. Details concerning injury, acute treatment, and clinical course and outcome were obtained from medical records and radiographs.
  
  
  RESULTS
  We identified 509 proximal femur fractures in patients older than 65 years of age, of which 32 (6.3%) were related to a high-energy trauma mechanism. The mean age in the study group was 72.2 years (range 65-87), with a mean injury severity score of 20 points (range 9-57). Three patients died before discharge (9.4%), and 22 of 32 patients sustained at least one complication (68.8%). Blunt chest trauma represented the most frequently associated injury, and the main root cause of pulmonary complications. The patients' age and comorbidities did not significantly correlate with the rate of complications and the 1-year mortality.
  
  
  CONCLUSIONS
  High-energy proximal femur fractures in elderly patients are not very common and are associated with a low in-hospital mortality rate of less than 10%, despite high rate of complications of nearly 70%. This selective cohort of patients requires a particular attention to respiratory management due to the high incidence of associated chest trauma.
