Developmental dysplasia of the hip (DDH) encompasses a wide pathological spectrum, from mild acetabular dysplasia to complete congenital hip dislocation at birth. Screening policies have been implemented in an effort to effectively identify and treat patients with DDH. Since 2009 there has been a national DDH programme in Chile. The current study evaluates the results of the programme in patients born between 2010 and 2015.
Records of patients hospitalized from 1st January 2010 to 31st December 2019 were retrieved from national databases. Those born from 1st January 2010 to 31st December 2015 who underwent a procedure for DDH under general anaesthesia during their first five years of life were selected. Sex, first surgical procedure and age at first surgical procedure were analyzed. The incidence of DDH that required major surgical treatment was calculated.
A total of 961 children born from 1st January 2010 to 31st December 2015 underwent a procedure for DDH during their first five years of life. The number of major procedures was significantly lower than the number of minor procedures (269 692). The incidence of major procedures was 0.18 per 1000 live births. Girls underwent a higher number of procedures than boys (831 130), whereas 39.2% of the boys and 26.2% of the girls had major procedures. The mean age at the time of the first procedure was 15.35 months (sd 10.09; range 0.03 to 55.92 months).
The present study suggests that the Chilean National DDH Screening Program is an appropriate programme with substantial benefits with respect to public health.

发育性髋关节发育不良（DDH）涵盖广泛的病理范围，从轻度髋臼发育不良到出生时完全性先天性髋关节脱位。已实施筛查政策以有效识别和治疗DDH患者。自2009年以来，智利实施了全国性DDH项目。本研究评估了该项目在2010年至2015年出生患者中的结果。
从国家数据库中检索2010年1月1日至2019年12月31日住院患者的记录。选取2010年1月1日至2015年12月31日出生且在其生命的前五年接受全身麻醉下DDH手术的患者。分析性别、首次手术方式和首次手术时的年龄。计算需要进行重大手术治疗的DDH发病率。
共有961名2010年1月1日至2015年12月31日出生的儿童在其生命的前五年接受了DDH手术。重大手术的数量明显低于小手术的数量（269对692）。重大手术的发病率为每1000例活产0.18例。女孩接受手术的数量多于男孩（831对130），而39.2%的男孩和26.2%的女孩进行了重大手术。首次手术时的平均年龄为15.35个月（标准差10.09；范围0.03至55.92个月）。
本研究表明，智利国家DDH筛查项目是一项合适的项目，对公共卫生有重大益处。
