ABSTRACT Complications after surgical treatment of pediatric radial neck fractures are common. The purpose of this study was to evaluate the mid- to long-term clinical and radiographic outcomes after surgical treatment of pediatric radial neck fractures. We assessed 10 children who had been surgically treated for radial neck fractures. We mainly performed percutaneous intrafocal pinning to reduce the fracture; where this was inappropriate, we performed open reduction. Mid- to long-term clinical and radiographic outcomes were assessed, as well as whether these affected patient-related outcomes (Hand 20 questionnaire) at the final follow-up. Of the 10 patients (seven boys; mean age, 9 years; age range, 5–14 years; four fractures on the right-hand side, six on the left), four each were grades II and III, and two were grade IV, according to the Judet classification. The mean follow-up time was 6.7 (range, 3.6–11.2) years. Eight patients had restricted forearm pronation. The mean radial neck angulation on the fractured side was 36° (range, 5°–96°), preoperatively, and 2° (range, 0°–11°) at the final follow-up. There were eight cases of radial head overgrowth, three of premature physeal closure, two of notching of the radial neck, and one of heterotopic ossification. According to the Leung/Peterson Classification, four patients had “excellent,” three had “good,” and three had “fair” functionality. Eight patients had a perfect score upon completing the Hand 20 questionnaire. In conclusion, postsurgical patient-related outcomes for the 10 cases were satisfactory despite slightly restricted forearm range of motion and complications detected using radiography.
