Background Supracondylar humerus fractures (SCHF) are the most common fractures sustained following a fall onto an outstretched hand among healthy children, and one of the leading causes of hospital admission and surgical intervention. The aim of this study was to examine SCHF occurring at public play spaces—particularly to determine whether or not the playground equipment implicated in injurious falls aligned with Canadian playground safety standards. Methods Cases of children who attended the provincial paediatric orthopaedic clinic following SCHF at a public playground between April 2017 and October 2019 were included in the study. A research assistant visited each playground to measure the play structure type and dimensions, height of the equipment at the point from which the child fell and the type and depth of the surface material, and compare measurements to the 2016 safety standards. Child demographics and injury classification were also noted. Descriptive statistics were calculated and a scatterplot of fall height and surface depth was generated. Results Forty-three sites, representing 47 SCHF cases (18 female, 29 male), were included in the final analysis. Fourteen children sustained type 1 fracture, 23 had type 2 fracture and the remaining 10 had type 3 fracture. Five children with type 2 fracture and all 10 children with type 3 fracture required surgery. The majority of sites had engineered wood fibre surfacing, with surfacing at 35 sites being less than 300 mm deep. Twenty-six play structures were upper body equipment (ie, monkey bars or similar), seven were track rides, five were rotating structures and the rest comprised a variety of classified and unclassified structures. Twenty-seven children fell from a height exceeding 2 m. Conclusions The majority of SCHF cases occurred at playgrounds with insufficient surface depth and/or non-compliant equipment. Upper body equipment, track rides and rotating play structures were of particular concern, as the children fell from heights exceeding the recommended standard, likely reflecting the degradation and compaction of the surfacing material over time. No data are available.

小儿肘部骨折和公共游乐空间：遵守儿童游乐设备和铺面标准

背景 肱骨髁上骨折 (SCHF) 是健康儿童跌倒在伸出的手上后最常见的骨折，也是住院和手术干预的主要原因之一。本研究的目的是检查公共游乐场所发生的 SCHF，特别是确定涉及伤害性跌倒的游乐场设备是否符合加拿大游乐场安全标准。方法 研究纳入 2017 年 4 月至 2019 年 10 月期间在公共游乐场因 SCHF 就诊于省儿科骨科诊所的儿童病例。一名研究助理参观了每个游乐场，以测量游乐设施的类型和尺寸、孩子跌倒点的设备高度以及表面材料的类型和深度，并将测量结果与 2016 年安全标准进行比较。还注意到儿童人口统计和伤害分类。计算描述性统计数据并生成坠落高度和表面深度的散点图。结果 43 个站点，代表 47 例 SCHF 病例（18 例女性，29 例男性）被纳入最终分析。14名儿童1型骨折，23名2型骨折，其余10名3型骨折。5 名 2 型骨折儿童和 10 名 3 型骨折儿童全部需要手术。大多数场地都进行了工程木纤维铺面，其中 35 个场地的铺面深度小于 300 毫米。26 个游乐设施是上身设备（即单杠或类似设备），7 个是轨道游乐设施，五个是轮换结构，其余包括各种机密和非机密结构。27 名儿童从超过 2 m 的高度坠落。结论 大多数 SCHF 病例发生在表面深度不足和/或设备不合规的游乐场。上身设备、轨道游乐设施和旋转游乐设施尤其值得关注，因为孩子们从超过推荐标准的高度坠落，这可能反映了随着时间的推移表面材料的退化和压实。没有可用的数据。当孩子们从超过推荐标准的高度坠落时，可能反映了表面材料随着时间的推移而退化和压实。没有可用的数据。当孩子们从超过推荐标准的高度坠落时，可能反映了表面材料随着时间的推移而退化和压实。没有可用的数据。
