title: Differential impact of some risk factors on trochanteric and cervical hip fractures.
abstract: OBJECTIVE
  To investigate the potential distinct risk factors associated with trochanteric and cervical hip fractures.
  
  
  METHODS
  Elderly patients aged 65 years and older (n = 1161) were admitted to the orthopedic department with hip fractures during the years 2006-2011. Demographic and clinical data, as well as routine blood tests, were retrieved from the patient electronic medical records.
  
  
  RESULTS
  Approximately 58% of patients had trochanteric fractures and 42% had cervical fractures. Women were more likely to have trochanteric fractures than men (P = 0.002). Female sex, frailty, falls, diabetes and subnormal calcium, as well as subnormal hemoglobin levels, were significant risk factors for trochanteric fractures (OR 1.39, P = 0.0202, OR 1.36, P = 0.0166, OR 1.49, P = 0.0015, OR 1.33, P = 0.0343, OR 0.68, P = 0.0054, OR 0.70, P = 0.0036, respectively). Patients with Parkinson's disease were at a lower risk for trochanteric fractures (OR 0.6, P = 0.007).
  
  
  CONCLUSIONS
  As there are some differences between risk factors for trochanteric and cervical hip fractures, there is a need for further studies in order to understand the etiology of fractures and to be able to carry out effective preventive efforts.
