Coracoid fracture is a rare injury. The aim of this study is to present the demographics, clinical and radiologic characteristics, and outcomes of coracoid fracture in a cohort of 32 patients.
We queried our institutional electronic medical record database (years 2012-2020) to identify patients with coracoid fractures using specific International Classification of Disease-10 codes. Demographic data, injury details including mechanism of injury and associated injuries, imaging performed, and treatment outcomes were obtained from retrospective chart review. A radiologist reviewed all available imaging studies (radiographs/CT/MRI) and classified the fractures according to Ogawa and Eyres classifications. Missed diagnoses were determined by comparing initial imaging reports with the follow-up imaging obtained in the office.
Thirty-two patients with coracoid fractures were identified during the study period. Sixteen fractures (50%) occurred in the setting of low-energy trauma. Twelve fractures were missed on initial radiographs, and diagnosis with three-view radiographs (AP, scapular-Y and axillary) was 88% compared to 33% (p < 0.03) with two views (AP, scapular-Y). The majority of fractures were non-displaced (94%), and 56% were Ogawa Type-II fractures. Associated injuries were seen in 81% of patients. Most fractures (94%) were treated without surgery with excellent outcomes.
Coracoid fractures continue to be a rare injury. In contrast to previous studies, in this case series of 32 patients, half of the fractures were associated with low-energy trauma, which correlated with higher percentage of non-displaced fractures and Ogawa Type-II fractures. Addition of the axillary view in the trauma radiographic series significantly improved the initial fracture detection rate.
Retrospective study.
喙突骨折较为少见。本研究旨在报告 32 例喙突骨折患者的人口统计学、临床和影像学特征及结局。
我们通过特定的国际疾病分类第 10 版代码，在我们的机构电子病历数据库（2012 年至 2020 年）中查询了患有喙突骨折的患者。从回顾性病历中获取人口统计学数据、损伤细节（包括损伤机制和相关损伤）、影像学检查和治疗结果。放射科医生回顾了所有可用的影像学研究（X 线片/CT/MRI），并根据 Ogawa 和 Eyres 分类对骨折进行分类。通过比较初始影像学报告和在诊所获得的随访影像学，确定漏诊。
在研究期间，共发现 32 例喙突骨折患者。16 例（50%）骨折发生于低能量创伤。12 例初始 X 线片漏诊，三视图（前后位、肩胛 Y 位和腋位）的诊断率为 88%，而两视图（前后位、肩胛 Y 位）的诊断率为 33%（p<0.03）。大多数骨折为无移位（94%），56%为 Ogawa Ⅱ型骨折。81%的患者存在合并损伤。大多数骨折（94%）未经手术治疗，结果良好。
喙突骨折仍是一种少见损伤。与之前的研究不同，在本 32 例病例系列中，有一半的骨折与低能量创伤有关，这与更高比例的无移位骨折和 Ogawa Ⅱ型骨折相关。在创伤影像学系列中增加腋位可显著提高初始骨折检出率。
IV 级：回顾性研究。
