DISTAL HUMERAL FRACTURE: AN EPIDEMIOLOGICAL ANALYSIS OF ORTHOPEDIC PATIENTS FOR CHILDREN

ABSTRACT Objective: To analyze the epidemiological profiles of children with orthopedic distal humerus fractures. Methods: An analytical descriptive study was conducted with a retrospective approach using medical records of 665 orthopedic children who attended the Jesser Amarante Faria Children's Hospital, a reference hospital in the city of Joinville, Santa Catarina, between June 2012 and December 2016. Results: The results showed a predominance of male patients (64.2%), with a mean age of 7 years, and the age group of 6–10 years being the most frequent with 319 patients (48%). The main mechanism of trauma was fall of height in 59.7% of patients, Gartland type 1 fracture in 57.1%, and absence of vascular injury in 99.7%. Conservative management was implemented in 64.7% (95%) of patients. Absence of neurological lesion (95.6%) and closed lesion (99.4%) were the main epidemiological characteristics of patients in the study. A low complication rate was observed, with reduction losses in 1.7% of patients, followed by infections in 1.1%. Conclusion: We can conclude that the cases studied presented epidemiological characteristics similar to those described in the literature. Level of evidence IV, Description of a case series, with analysis of results, without a comparative study.

摘要
研究目的：分析儿童肱骨远端骨折患者的流行病学特征。
研究方法：本研究采用回顾性描述性分析设计，纳入2012年6月至2016年12月期间，就诊于巴西圣卡塔琳娜州若因维利市区域转诊医院——杰西·阿马拉兰特·法里亚儿童医院（Jesser Amarante Faria Children's Hospital）的665名骨科儿童的临床病历资料。
研究结果：结果显示，男性患者占比64.2%，患者平均年龄为7岁，6~10岁年龄段为高发年龄段，共319例患者，占总例数的48%。主要创伤机制为高处坠落，占比59.7%；Gartland Ⅰ型骨折（Gartland type 1 fracture）占比57.1%，99.7%的患者未合并血管损伤。64.7%的患者接受了保守治疗（95%），95.6%的患者无神经损伤，99.4%为闭合性损伤，上述为本次研究患者的主要流行病学特征。本研究并发症发生率较低，其中复位丢失占1.7%，感染占1.1%。
研究结论：本研究纳入病例的流行病学特征与现有文献报道结果相似。本研究证据等级为Ⅳ级，属于病例系列描述研究，仅对研究结果进行分析，未设置对照研究。
