title: [Treatment of calcaneal fractures by fixation of Kirschner needle and thread cancellous bone screw through sinus tarsi interstice].
abstract: OBJECTIVE
  To explore the effect of fixation of Kirschner needle and thread cancellous bone screw through the sinus tarsi interstice for the treatment of calcaneal fractures.
  
  
  METHODS
  From January 2009 to December 2012,20 patients with calcaneal fracture were treated by minimally invasive Kirschner wire and threaded cancellous bone screw fixation and bone graft,including 12 males and 8 females with an average age of 39 years old ranging from 21 to 65. Among them, 8 cases were left foot, 12 were right foot. According to Sanders's classification, 8 cases were type II, 10 cases were type III, 2 cases were type IV.
  
  
  RESULTS
  All patients were followed up from 6 to 16 months with an average of 12 months. The incision were healed. Böhler angle were increased from preoperative (17.75 +/- 4.22) degrees to postoperative (26.85 +/- 7.37) degrees (t = 4.308, P = 0.000). Gissane angle were reduced from preoperative (137.05 +/- 24.91) degrees to postoperative (113.75 +/- 13.17) degrees (t = 7.083, P = 0.000). At 3 months after operation, the scores of AOFAS were 85.50 +/- 7.99; the results were excellent in 5 feet and good in 11 feet, fair in 3 feet, and poor in 1 foot.
  
  
  CONCLUSIONS
  Minimally invasive fixation of Kirschner needle and thread cancellous bone screw fixation is a simple operation, it can get reliable fixation, easy to remove, low cost, less postoperative complications, and it is a good treatment of calcaneal fracture.
