Comparison of the Effect of Close Reduction Kirschner Wire Intramedullary Fixation and Crossing Fixation in the Treatment of Distal Fracture of Radius in Children
Objective:To explore the effect of close reduction Kirschner wire intramedullary fixation and crossing fixation in the treatment of distal fracture of radius in children.Method:Clinical data of 80 children with distal fracture of radius admitted to Department of Surgery,Jiangxi Provincial Children's Hospital from May 2020 to March 2023 were selected for retrospective study,and they were divided into two groups according to the different fixation methods of Kirschner wire.The intramedullary fixation group(n=40)underwent close reduction Kirschner wire intramedullary fixation,and the crossing fixation group(n=40)underwent close reduction Kirschner wire crossing fixation.The short-term effect,surgical indexes,recovery indexes,incidence of malunion of fracture and fracture redisplacement,carpal joint function[patient-rated wrist evaluation(PRWE),Dienst function score]and postoperative complications were compared between the two groups.Result:At 4 weeks after surgery,ulnar inclination,palmar tilt and radial shortening length in both groups were improved significantly,ulnar inclination and palmar tilt in intramedullary fixation group were greater than those in crossing fixation group,and the radial shortening length was shorter than that in crossing fixation group(P<0.05).There were no significant differences in operation time,intraoperative bleeding volume,intraoperative fluoroscopy times,hospital stay,treatment cost,malunion of fracture rate,excellent and good rate and complication rate between the two groups(P>0.05).The fracture healing time of intramedullary fixation group was shorter than that of crossing fixation group,and the incidence of fracture redisplacement was lower than that in crossing fixation group(P<0.05).The PRWE scores of intramedullary fixation group at 2,4 and 8 weeks after surgery were lower than those of crossing fixation group(P<0.05).Conclusion:In children with distal fracture of radius,the short-term effect of close reduction Kirschner wire intramedullary fixation is better than that of crossing fixation,which can increase stability and accelerate fracture healing,but there is no significant difference in safety between the two methods of needle placement.
