Closed reduction by trans-physealantegrade elastic stable intramedullary nailing in acute pediatric Monteggia fractures: a report of 22 cases.

ABSTRACT

Treatment of acute pediatric Monteggia fractures is still debated. The aim of this study was to assess the efficacy of strategy based on closed reduction by trans-physeal antegrade elastic stable intramedullary nailing (ESIN) of the ulnar fracture. Retrospective analysis of 22 patients (13 boys and nine girls) treated for acute Monteggia fractures between May 2008 and August 2018 was performed. Mean age at injury was 6.6 years. Mean follow-up was 4.5 years. On the basis of the Bado classification, 15 lesions were of type I, three types III and four types IV. All the patients were managed with closed reduction and ESIN of the ulna fracture within 2-19 h of arrival. Intraoperative stability of reduction of the radial head was checked under fluoroscopic control in pronation and supination. Outcomes were assessed with the Bruce et al. scoring system. Closed alignment of the ulnar fracture by ESIN had simultaneously reduced and stabilized the radial head dislocation in all patients. At the final follow-up, all the patients had excellent results. Complete healing of the fracture occurred in 6 weeks and the elastic nail removed at 3-6 months postoperatively. There was no case of instability or subluxation or re-dislocation of the radial head. No olecranon epiphysiodesis or growth disorders were noticed. Early diagnosis and management of acute pediatric Monteggia fractures by closed reduction and ESIN achieve excellent clinical and radiographic outcomes.
