Li XT, Shen XT, Wu X, et al. - This study was sought to present an ultrasound-assisted closed reduction and percutaneous pinning technique and ascertain its utility in the treatment of displaced and rotated lateral condylar humeral fractures in children. Researchers successfully treated 42 of 44 displaced and rotated pediatric lateral humeral condyle fractures with ultrasound-assisted closed reduction and percutaneous pinning between 2013 and 2018. They assessed postoperative data in terms of Kirschner wire in situ duration, follow-up duration, range of motion, carrying angle, cosmetic result, and complications. The results of this study indicated that the surgical technique of ultrasound-assisted closed reduction and percutaneous pinning presented can effectively help surgeons reduce displaced and rotated lateral condylar humeral fractures in children to avoid some open reductions and achieve satisfactory outcomes.
