This study aims to investigate risk factors for refracture of the forearm in children treated with elastic stable intramedullary nailing (ESIN).
Clinical data of 267 patients who had been treated for forearm fractures by ESIN in our hospital from January 2010 to December 2014 were retrospectively reviewed. Risk factors for forearm refractures were determined using logistic regression analysis.
Forearm refractures occurred in 11 children. Univariate analysis revealed that age, body weight, number of fractures, open fracture, nail diameter, and immobilization time were not associated with refractures. However, gender (male, P = 0.042) and fracture location (lower third, P = 0.007) were significantly associated with refractures. Multivariate analysis revealed that fracture location was an independent risk factor for forearm refractures (P = 0.031).
Forearm refracture is uncommon in children treated with ESIN. Fracture location is an independent risk factor for forearm refractures in these patients.
本研究旨在探讨弹性髓内钉（ESIN）治疗儿童前臂骨折后再骨折的危险因素。
回顾性分析 2010 年 1 月至 2014 年 12 月我院采用 ESIN 治疗的 267 例前臂骨折患儿的临床资料。采用 logistic 回归分析确定前臂再骨折的危险因素。
11 例患儿发生前臂再骨折。单因素分析显示，年龄、体质量、骨折数量、开放性骨折、髓内钉直径和固定时间与再骨折无关。然而，性别（男性，P=0.042）和骨折部位（下段，P=0.007）与再骨折显著相关。多因素分析显示，骨折部位是前臂再骨折的独立危险因素（P=0.031）。
ESIN 治疗儿童前臂骨折后再骨折并不常见。骨折部位是此类患者发生前臂再骨折的独立危险因素。
