ABSTRACT

Objective To investigate the closed replacement via internal and external crossed fixation with three kirschner wires on treating supracondylar fracture of humerus in children.Methods One hundred and six patients with supracondylar fracture of humerus in Osteopathic Hospital of Nanyang City from June 2010 to July 2015were divided into control group and observation group.Fifty patients in the control group were given closed replacement via external crossed fixation with three kirschner wires,while fifty-six patients in the observation were given closed replacement via internal and external crossed fixation with three kirschner wires.The visual analogue scales(VAS) score was recorded in the two groups before and after treatment.The curative effect was evaluated by Flynn elbow function evaluation standard and the incidence of postoperative complication was compared between the two groups.Results All the patients were followed up for 3-24 months.The time of fracture healing in the control group and the observation group was (6.0 ± 1.0) weeks and (5.6 ± 1.0) weeks respectively,there was no significant difference in the time of fracture healing between the two groups(P ＞0.05).There was no significant difference in the VAS score before treatment in the two groups (P ＞ 0.05).After treatment the VAS score in the two groups was lower than that before treatment(P ＜ 0.05),and the VAS score in the observation group was lower than that in the control group (P ＜0.05).The therapeutic efficiency in the control group and the observation group was 74.00％ (37/50) and 91.07％(51/56),respectively.The therapeutic efficiency in the observation group was higher than that in the control group(x2 =5.461,P ＜ 0.05).The incidence of postoperative complication in the control group and the observation group was 16.00％ (8/50) and 3.57％ (2/56),respectively.The incidence of postoperative complication in the observation group was lower than that in the control group (x2 =4.624,P ＜ 0.05).Conclusion Comparing with the treatment of closed replacement via external crossed fixation with three kirschner wires,therapeutic efficiency of the closed replacement via internal and external crossed fixation with three kirschner wires in treating children supracondylar fracture of humerus is more obviously and the incidence of postoperative complication is lower.
