Refracture is one of the most common complications of pediatric forearm fractures. One way to decrease this risk is to extend immobilization with a brace after the cast has been removed to allow for a range of motion exercises. The purpose of this study was to examine whether prescribing a brace after casting was discontinued decreased the risk of refracture. A retrospective, cohort study was performed at one level I trauma center. Girls under 10 years and boys under 12 years who sustained a forearm fracture from January 2013 to December 2018 were included. Patients with open fractures, fractures that required operative intervention, fractures involving the physis, fracture-dislocations, floating elbows, fractures in children with endocrine abnormalities, and fractures in patients lost to follow-up were excluded. The primary endpoint was a refracture within 6 months of the original injury that extended through the original fracture site. In total 2093 patients met the inclusion criteria. There were 19 refractures (0.9%). There was no statistically significant difference in the refracture rate between the braced (11/1091) and unbraced (8/1002) cohorts (Fisher exact value 0.65 at P < 0.05). The most common fracture type that went on to refracture was greenstick fractures. This large, retrospective study aimed to examine whether prescribing a brace had any significant effect on the refracture rate. Bracing after the cast is removed may help ease family anxiety and extend the period of immobilization while allowing for hygiene and range of motion, but it does not significantly decrease the rate of refracture.

再次骨折是儿童前臂骨折最常见的并发症之一。降低这种风险的一种方法是在拆除石膏后用支架延长固定时间，以便进行一系列的运动练习。本研究的目的是检查停止铸造后使用支具是否可以降低再骨折的风险。在一个一级创伤中心进行了一项回顾性队列研究。纳入对象为2013年1月至2018年12月期间发生前臂骨折的10岁以下女孩和12岁以下男孩。排除开放性骨折、需要手术干预的骨折、累及骺板骨折、骨折脱位、浮动肘、内分泌异常儿童骨折以及失访患者骨折的患者。主要终点是原始损伤后 6 个月内延伸至原始骨折部位的再骨折。总共 2093 名患者符合纳入标准。再次骨折 19 例（0.9%）。支具组 (11/1091) 和未支具组 (8/1002) 之间的再骨折率无统计学显着性差异（Fisher 精确值 0.65， P  < 0.05）。最常见的再骨折类型是青枝骨折。这项大型回顾性研究旨在检查使用支具是否对再骨折率有显着影响。拆除石膏后进行支撑可能有助于缓解家人的焦虑并延长固定时间，同时考虑到卫生和活动范围，但它不会显着降低再骨折的发生率。
