Rotator cuff injuries (RCIs), traditionally thought to be an adult-type pathology, have been reported in the pediatric population, but there remains limited evidence regarding this injury pattern in pediatric patients. The purpose of this study was to systematically review the literature to characterize the epidemiology, injury patterns, treatment modalities, and outcomes for pediatric patients with RCIs. A systematic review was performed in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, reviewing Pubmed, Embase, Cochrane, and CINAHL databases. Studies reporting imaging confirmed RCIs, and treatment outcomes in patients less than 18 years of age were included. Patient demographics, mechanism, injury type, and injury location were recorded. Treatment type and patient outcomes were abstracted when available and summarized with descriptive statistics. Our search identified 28 studies published from 1994 to 2020, which included 215 total tendons injured in 185 patients. Twenty-six studies were classified as level IV evidence, whereas only two were level III. When described, the most injured tendon (n = 184) was the supraspinatus, whereas the most described injury type (n = 215) was a partial tear. Surgical intervention was pursued in 75.8% of injuries, with arthroscopy being more common than open repair (79.4% vs. 20.6%). Nonoperative treatment was primarily utilized for partial tears. Among the 24 studies reporting on return to sports, nonoperatively managed patients returned later than those treated operatively (mean: 10.7 vs. 7 months). Only eight studies included patient reported outcome measures (PROMs), and just five had pre- and posttreatment scores. Three complications were noted, all in operative patients. RCIs in pediatric patients have been reported in the literature with increasing frequency over the last decade, but the quality of evidence remains poor with inconsistent injury descriptions and outcome reporting. Excellent results were seen for all injury types and locations with both operative and nonoperative treatments. The literature for pediatric RCIs remains limited in guiding management decisions indicating a need for more high-quality studies to compare outcomes across injury and treatment type. Level of evidence: level III.

肩袖损伤 (RCI) 传统上被认为是一种成人型病理，但在儿科人群中已有报道，但有关儿科患者这种损伤模式的证据仍然有限。本研究的目的是系统回顾文献，以描述 RCI 儿科患者的流行病学、损伤模式、治疗方式和结果。根据系统审查和荟萃分析的首选报告项目 (PRISMA) 指南进行了系统审查，审查了 Pubmed、Embase、Cochrane 和 CINAHL数据库。报告影像学证实 RCI 的研究，以及 18 岁以下患者的治疗结果也包括在内。记录患者人口统计数据、机制、损伤类型和损伤位置。治疗类型和患者结果在可用时进行抽象，并用描述性统计数据进行总结。我们的搜索找到了 1994 年至 2020 年发表的 28 项研究，其中包括 185 名患者的 215 根肌腱受伤。26 项研究被列为 IV 级证据，而只有两项研究被列为 III 级证据。描述时，受伤最严重的肌腱 ( n = 184) 是冈上肌，而描述最多的损伤类型 ( n = 215) 是部分撕裂。75.8% 的损伤采取手术干预，其中关节镜检查比开放修复更常见（79.4% vs. 20.6%）。非手术治疗主要用于部分撕裂。在 24 项报告恢复运动的研究中，非手术治疗的患者比手术治疗的患者恢复时间晚（平均：10.7 个月对 7 个月）。只有八项研究纳入了患者报告的结果测量（PROM），并且只有五项研究有治疗前和治疗后的评分。注意到三种并发症，全部发生在手术患者中。过去十年，文献中报道儿科患者 RCI 的频率不断增加，但证据质量仍然很差，损伤描述和结果报告不一致。对于所有损伤类型和部位，手术和非手术治疗均取得了优异的效果。儿科 RCI 的文献在指导管理决策方面仍然有限，表明需要更多高质量的研究来比较不同损伤和治疗类型的结果。证据级别：III级。
