title: [Closed reduction and percutaneous hollow screw fixation with prototypical retractor for the treatment of calcaneal fracture].
abstract: OBJECTIVE
  To evaluate efficacy of closed reduction and percutaneous hollow screw fixation with prototypical retractor in treating calcaneal fracture.
  
  
  METHODS
  From January 2009 to June 2011, 39 patients (43 feet) with calcaneal fracture were treated by closed reduction and percutaneous hollow screw fixation with prototypical retractor. There were 33 males and 6 females, aged from 19 to 61 years with an average of 36.7 years. According to type of Sanders, type II were in 19 feet, type III were in 24 feet. Preoperative and postoperative X-ray were estimated, the data of height, width, Bölher angle, Gissane angle of calcaneous were collected, and ankle function were estimated according to AOFAS system.
  
  
  RESULTS
  All patients were followed up from 6 to 36 months with an average of (15.4 +/- 3.1) months. All wounds were healed well, no skin edge necrosis and infections occurred. Before operation, the height of calcaneous was average of (32.45 +/- 3.51) mm, width was (41.60 +/- 2.42) mm, Bölher angle was (8.64 +/- 13.2) degrees and Gissan angle was (136.35 +/- 15.23) degrees; while after operation, the height of calcaneous was average of (43.62 +/- 1.02) mm, width was (38.02 +/- 1.28) mm, Bölher angle was (26.87 +/- 5.32) degrees and Gissan angle was (120.78 +/- 5.34) degrees, and had significanty differences between preoperative and postoperative treatment (P<0.05). AOFAS score was improved from preoperative (35.64 +/- 11.23) to postoperative (76.18 +/- 9.87), and 29 cases got excellent results, 11 good and 3 fair. COMCLUSION: Closed reduction and percutaneous hollow screw fixation auxiliary by the retractor for the treatment is a good way, which has advantages of simple operation, satisfactory reduction fixation, reliable fixation, minimally invasive, less complications and rapid recovery.
