title: Epidemiology of fractures of the proximal third of the femur in elderly patients.
abstract: OBJECTIVE
  This was an epidemiological study on fractures of the proximal third of the femur in elderly patients who were treated at a teaching hospital in the central region of São Paulo.
  
  
  METHODS
  The subjects were patients over the age of 60 years who were attended over a 1-year period. A questionnaire seeking basic sociodemographic data and information on comorbidities presented and medications used was drawn up. The circumstances of the fractures and their characteristics, the treatment instituted and the intra-hospital mortality rate were evaluated.
  
  
  RESULTS
  The 113 patients included in the study presented a mean age of 79 years. The ratio between the sexes was three women to each man. Only 30.4% of the patients reported having osteoporosis and only 0.9% had had treatment for the disease. Low-energy trauma was the cause of 92.9% of the fractures. Femoral neck fractures accounted for 42.5% of the fractures and trochanteric fractures, 57.5%. Five patients did not undergo operations; 39 underwent joint replacement; and 69 underwent osteosynthesis. The mean length of hospital stay was 13.5 days and the mean length of waiting time until surgery was 7 days. The intra-hospital mortality rate was 7.1%.
  
  
  CONCLUSIONS
  The patients attended at this institution presented an epidemiological profile similar to what is found in the Brazilian literature. Chronic kidney failure is a significant factor with regard to intra-hospital mortality. Preventive measures such as early diagnosis and treatment of osteoporosis and regular physical activity practices were not implemented.
