Open Reduction of Displaced Radial Neck Fractures in Children by Internal Fixation Techniques: Comparison of Percutaneous Kirschner Wiring and Elastic Stable Intramedullary Nailing.

Background: Although most paediatric radial neck fractures can be treated with closed reduction, some severely displaced fractures require open reduction. The purpose of this study is to compare the effects of ESIN and KW fixation in open reduction of radial neck fracture in children.
Methods: Twenty-four patients with mean age of 8.5 years were included. Four of the patients had a Judet type III fracture and 20 had a Judet type IV fracture. Ten patients who underwent percutaneous KW fixation were assigned to group A, while 14 patients who underwent ESIN fixation were assigned to group B. Variables of interest included age, sex, fracture type, associated lesions, surgical time, fracture reduction, cost, follow-up, healing time, X-rays, clinical outcomes, and complications.
Results: There were no significant between-group differences in sex, age, additional injuries, fracture type, and quality of reduction. Costs were significantly lower in Group A. Fracture healing was achieved in 23 of 24 patients (10/10 in group A and 13/14 in group B). In a postoperative elbow function assessment based on the Steele and Graham classification, 80% of patients in group A had a score of excellent or good, compared to 78.6% of patients in group B. Two cases of nail shifting and joint protrusion were observed in group B, one of which also presented with nonunion during follow-up. Conclusions: Both KW and ESIN may achieve good clinical outcomes, but KW is associated with lower costs, easier implant removal (without the need for a secondary surgery), and lower iatrogenic complications. © Indian Orthopaedics Association 2022.
