Ultrasonography-Guided Combination with Elbow Arthrography-Assisted Minimally Invasive Treatment of Radial Neck Fractures in Young Children

Abstract

Background. A radius neck fracture in children is a common fracture that not only affects the growth and development of children but also has a certain impact on the function of children’s elbow joints. Objective. To probe into the application value of ultrasonography- (US-) guided combination with elbow arthrography in the minimally invasive treatment of radial neck fractures in young children, summarize its clinical effect and provide a minimally invasive, safe, effective, and reliable method for treating radial neck fractures in young children. Methods. Seventy-three patients with type III or IV radial neck fractures were treated from June 2013 to December 2020 and were divided into the Métaizeau group ( $n=31$ , treatment group) and Kirschner wire ( $k$ -wire) $k$ -wire group ( $n=42$ , control group). The Métaizeau group was given US-guided combination with elbow arthrography-assisted modified Métaizeau technique, the $k$ -wire group received open reduction and internal fixation with $k$ -wire and compared the surgical effect of the two groups. Results. In comparison with the $k$ -wire group, time of operation, intraoperative bleeding volume, and hospital stay were signally junior to those in the Métaizeau group ( $P<0.05$ ). After surgery, in comparison with the $k$ -wire group, the number of degrees to contralateral flexion or forearm rotation was visually lower in the Métaizeau group ( $P<0.05$ ), and postoperative complication incidence in the Métaizeau group was visually lower than that in $k$ -wire group ( $P<0.05$ ). Conclusion. In the minimally invasive treatment of radial neck fractures, US-guided combination with elbow arthrography in young children has better efficacy and high safety. It can be widely promoted and applied clinically.
