title: [Case-control study on percutaneous treatment of foot Jones fracture with cannulated screws].
abstract: OBJECTIVE
  To compare clinical effects between plaster fixation and cannulated screw for the treatment of Jones fracture.
  
  
  METHODS
  From 2006 to 2010, 41 patients with Jones fractures were divided into 2 groups. In Group A, there were 14 males and 8 females, ranging in age from 21 to 62 years, with an average of (32.3 +/- 8.7) years; the course of disease ranged from 2 h to 3 d; the patients in Group A were treated with plaster fixation. In Group B, there were 9 males and 10 females, ranging in age from 24 to 59 years, with an average of (28.8 +/- 7.9) years; the course of disease ranged from 0.5 h to 2 d; the patients in Group B were treated with cannulated screw fixation. The patients in two groups were followed up from a long time and the long-term effects were studied.
  
  
  RESULTS
  All the 41 patients were followed up, from 3 months to 2.5 years, with a mean of 11.3 months. All the patients in both groups were healed. The patients in Group B got postoperative wound healing with A degree at the first stage without complications. In accordance with the Maryland Foot Score, the therapeutic effect in Group B was better than that of Group A. The healing time in Group B was shorter than that of Group A.
  
  
  CONCLUSIONS
  Percutaneous minimally invasive treatment with micro-cannulated screw is an ideal method for the treatment of the Jones fracture.
