The long-term results of treating radial neck fractures in children with the Metaizeau technique.

Abstract

Radial neck fractures in children are rare, representing less than 1% of all pediatric fractures. While conservative treatments are often sufficient, displaced fractures may require closed or open reduction. The Metaizeau technique is widely accepted for closed reduction and internal fixation. This study aims to assess the long-term functional and radiological outcomes of this technique and identify any complications that may arise. This retrospective study analyzed 22 pediatric patients treated with the Metaizeau technique for proximal radius fractures between 2005 and 2018. Data on demographics, preoperative radiographs, and postoperative complications were reviewed. Outcomes were evaluated using radiographic and functional measures, including grip strength, the Mayo elbow performance score (MEPS), and the Tibone and Stolz classification. The mean age at the time of injury was 9.9 years, with a mean follow-up period of 139 months (range: 72-213 months). Patients were classified as Judet type 3 (<i>n</i> = 9), type 4a (<i>n</i> = 9), or type 4b (<i>n</i> = 4). The functional outcomes showed a mean MEPS score of 99 (range: 90-100), with 86% of patients achieving excellent results according to the Tibone and Stolz classification. Excellent outcomes were recorded in 100% of type 3, 77.7% of type 4a, and 75% of type 4b cases. Documented complications included one case of radioulnar synostosis and two cases of heterotopic ossification. The Metaizeau technique represents an efficacious treatment option for pediatric radial neck fractures, offering favorable long-term functional and radiological outcomes with a low complication rate. Long-term follow-up data further support the reliability of this technique. Level IV.
