title: [Risk factors of the failure in digit replantation].
abstract: OBJECTIVE
  To explore the relative factors on the failure in digit replantation in order to take preventions to control the risk factors.
  
  
  METHODS
  From January 2013 to December 2013, 236 consecutive patients (311 fingers) underwent digit replantation were collected to analyze retrospectively, involving 183 males and 53 females with an average age of 34.5 years old ranging from 2 to 62 years old (6 cases under 6 years old and 230 cases elder than 6 years old). There were 51 thumbs, 87 index fingers, 78 middle fingers, 63 ring fings and 32 little thumbs. Forty cases(forty fings) who were failured as the observation group, the others as the control group. The factors of age, gender, finger, cause of injury, smoking history, ischemia duration, plane of division, condition of venous drainage and condition of arterial repair we assessed.
  
  
  RESULTS
  All 236 cases with 311 fingers were replanted, 40 fingers were failured after operation. The relative factors on the failure in digit replantation included smoking history, cause of injury, plane of division, condition of venous drainage and condition of arterial repair (P< 0.05). There were no significant correlation between the failure and age, gender, finger and ischemia duration (P>0.05).
  
  
  CONCLUSIONS
  Smoking history, causes of injury, plane of division, condition of venous drainage and condition of arterial repair are risks of failure in digit replantation. Before choosing the type of operation, it should be think about the patient's general conditions, injury status, grasp firmly the operative indications and actively carry out surgical treatment.
