Effects of Kirschner wire combined with cannulated screw internal fixation versus kirschner wire internal fixation alone on fresh lateral humeral condyle fractures in children: a comparative study

Objective To compare the clinical effects and use of open reduction plus Kirschner wire combined with cannulated screw internal fixation and open reduction plus Kirschner wire internal fixation alone in the treatment of lateral humeral condyle fractures. Methods Sixty-four patients with Jacob types Ⅱ or Ⅲ lateral humeral condyle fractures, who stayed in our department between January 2015 and August 2017, were included in the study and divided into two groups according to different treatment methods. Patients who underwent open reduction plus Kirschner wire internal fixation alone were included in the control group (n=30) , and those who underwent open reduction plus Kirschner wire combined with cannulated screw internal fixation were included in the study group (n=34) . The good efficacy rate of treatment, operation time, fracture healing time, incidence of wound infection and complications of fracture re-displacement were compared between the two groups. Results The good efficacy rate of treatment, operation time and fracture healing time in the control group and study group were 83.33% vs 97.06%, (46±13) min vs (50±16) min, and (13.0±2.2) weeks vs (8.7±1.0) weeks, respectively (P<0.05) . Conclusion The effect of open reduction plus Kirschner wire combined with cannulated screw internal fixation for the treating bone displacement due to fresh lateral humeral condyle fractures in children is better compared with open reduction plus Kirschner wire internal fixation alone.
