title: Risk factors of venous thrombosis in patients with ankle fractures.
abstract: OBJECTIVE
  Deep vein thrombosis (DVT) is a major complication that can occur after injuries. our aim was to explore the incidence and risk factors of venous thromboembolism in patients with ankle fractures.
  
  
  METHODS
  Consecutive patients with an isolated fracture of the ankle presenting at our centre between Sept 2004 and May 2012 were studied. They were investigated for venous thrombosis by Doppler sonography (DUS) before surgery. Univariate and multivariate logistic regressions analyses were performed to identify the incidence and risk factors for venous thromboembolism.
  
  
  RESULTS
  A total of 2347 patients were studied in the research. Of these, only 119 patients suffered from DVT. The multivariable analyses showed that diabetes, less activity and the time from injury were the key risk factors for thrombosis.
  
  
  CONCLUSIONS
  In patients with ankle fracture, the risk of thrombosis was low and it may not need warrant routine thromboprophylaxis. However, most cases had no significant symptoms, is necessary to grasp the indications for high risk patients to reduce the incidence rate of venous thrombosis.
