Abstract：Objective To investigate the methods and therapeutic efficacy of percutaneous reduction and elastic stable intramedullary nail fixation for pediatric radial neck fractures.Methods A retrospective analysis was conducted of the clinical data on radial neck fractures treated with percutaneous reduction and elastic stable intramedullary nail fixation in Beijing Children’s Hospital between January 2009 and January 2017. According to the Judet system, children of Judet Ⅲ and Ⅳ were treated by surgery. The effects of surgical reduction were evaluated according to the Metaizeau reduction standard, and the prognosis was evaluated according to the standard of Metaizeau in the last follow-up.Results All the patients were followed up for (36.98±18.98) months (9-100 months). A total of 60 patients were enrolled in this study, 25 males and 35 females. The median age was (7.27±2.76) years (ranging from 2 to 12 years). According to the Judet system, there were 44 cases of type Ⅲ, 9 cases of type Ⅳa, and 7 cases of type Ⅳb. There were 41 cases of simple radial neck fractures, 18 cases complicated with olecranon fractures and 1 case with the medial epicondyle fracture. According to Metaizeau reduction standard, the effect was excellent in 48 cases, good in 12 cases, insignificant in 0 case and poor in 0 case. According to clinical classification of Metaizeau, the effect was excellent in 55 cases, good in 5 cases, insignificant in 0 case and poor in 0 case.Conclusions Percutaneous reduction and elastic stable intramedullary nail fixation is effective in the treatment of pediatric radial neck fractures,with advantages of less epiphyseal injury,stable fixation,early post-operative training and good elbow joint function recovery.
