title: [Postoperative complications after femoral neck fracture in advanced elderly patients].
abstract: BACKGROUND
  We studied the prevalence of postoperative complications and the predictor for the occurrence of postoperative delirium in patients who had received surgery for femoral neck fracture.
  
  
  METHODS
  A retrospective study, covering the period between January 1, 2005 and March 31, 2006, was carried out 50 in patients of advanced age treated for femoral neck fracture. We investigated main symptoms of postoperative complications. We also compared postoperative delirium group (D group) with no delirium group (ND group).
  
  
  RESULTS
  The following results were obtained. Main postoperative complications were delirium, hypotension and hypoxia. And only one death case was included. In postoperative delirium, there was not a wide difference between the two groups except for hearing loss.
  
  
  CONCLUSIONS
  Our results indicate that it might be possible to prevent postoperative complications by careful perioperative management. Hearing loss preoperatively was a risk factor of postoperative delirium in advanced elderly patients.
