RESUMO
Objective To compare the clinical effects on Gartland type Ⅲ fractures in children by open reduction and external fixation with two parallel Kirschner wires and closed reduction.Methods From February 2013 to October 2016,84 children with Gartland type Ⅲ supracondylar fracture of humerus were selected and randomly divided into a control group and an observation group,each with a total of 42 cases.The control group received closed reduction treatment,and the observation group received open and external fixation with two parallel Kirschner wires.The two groups were compared on intraoperative blood loss,incision length,operating time,decreased degrees of carrying angle,reduced flexion-extension at the fractured side and the rates for good and excellent clinical effects.Results The observation group behaved significantly better than the control group in intraoperative blood loss,incision length and operating time (P＜0.05).The rates for good and excellent effects was 90.47％ in the observation group and 73.81％ in the control group,and there was obvious difference between the values in the two groups (P＜0.05).The observation group had the decreased degree of carrying angle statistically lower than that in the control group (P＜0.05),while the reduced flexion-extension at the fractured side was not significantly different from that in the control group (P＞0.05).Conclusion Open reduction and external fixation with two parallel Kirschner wires and closed reduction both gain their advantages when used to treat Gartland type llⅢ fractures in children,the former has high clinical effect,significantly recovered elbow joint function and low incidence rate for cubitus varus,and the latter has slight invasion,small incision while relatively low clinical effect and high incidence rate for cubitus varus.
