Objective To investigate and assess the clinical effect of treatment of children′s fractures at distal radial or radial-ulna through incision and Kirschner wire′s interior fixation without coursing epiphysis.Methods The treatment of children′s fractures at distal radial or radial-ulna in our hospital between 1996 and 2005 were reviewed,91 cases via Kirsehner-wire′s internal fixation were dealt.According to the way of placing Kirschner wire,the patients were divided into 2 groups.Group A of 53 cases eschewing epiphysis and passed bone-cortex.Group B of 38 cases got intramedullary fixation and passed epiphysis for 38 cases.After 6-100 months′ follow-up investigation,the 2 groups were comporred by analyzing statistics and the number of cases which involved repeatedly setting of Kirschner wire during operation,anatomical restoration,replacement,Kirschner-wire moving,infection,wrist′s dysfunction and bridge between the epiphysis.Results The fractures in both groups were recovering well.Besides,both were at the low rate of repeated replacement,Kirschner wire moving and infection.However,there were significant differences on repeated setting of Kirschner wire during operation,wrist′s dysfunction and bridge between the epiphysis,of which group B were higher than those in group A.Conclusions While the children′s fractures at distal radial or radial-ulna will be reduced by incision and fixing with Kirschner wire,the way of eschewing epiphyses and passing bone-cortex is better because it accords with anatomic character of children.It can not only fix reliably and bring satisfying clinical treatment effect,but also cause little complication.Thus,it is superior to the way of intramedullary fixation and passed epihysis.
