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

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.
