Treatment of calcaneal fractures by fixation of Kirschner needle and thread cancellous bone screw through sinus tarsi interstice / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
