title: [Analysis of risk factors for cerebral infarction after hip arthroplasty].
abstract: OBJECTIVE
  To investigate the independent risk factors for cerebral infarction so as to provide a theoretical basis for the prevention of cerebral infarction after total hip arthroplasty.
  
  
  METHODS
  A retrospective analysis of 571 patients for hip arthroplasty was conducted from January 2003 to September 2008. Twenty-three patients were found with cerebral infarction postoperatively. Single-factor and multi-factor correlation analyses were tested for the patients with cerebral infarction after hip arthroplasty.
  
  
  RESULTS
  The single-factor analysis for hip arthroplasty revealed that age (P = 0.001) and femoral neck fracture (P = 0.008) were the main factors for cerebral infarction. Furthermore, age was considered a risk factor for cerebral infarction after hip arthroplasty in multi-factor analysis (P = 0.029, OR = 1.054, 95%CI: 1.005 - 1.105).
  
  
  CONCLUSIONS
  Advanced age (> 70 yr) and femoral neck fracture are the main independent risk factors for cerebral infarction after hip arthroplasty.
