Abstract

Background: A national analysis of clavicle fractures is lacking and the risk of concomitant axillosubclavian vessel injury (ASVI) in patients with clavicle fractures is unknown. A minority of patients may have a combined brachial plexus injury (BPI). We sought to describe risk factors for concomitant ASVI in patients with a clavicle fracture; hypothesizing patients with combined clavicle fracture and BPI has a higher risk of ASVI. Methods: The Trauma Quality Improvement Program (2010-2016) was queried for blunt trauma patients with a clavicle fracture. A multivariable logistic regression model was used to determine risk factors for ASVI. A subset analysis on patients with isolated clavicle fractures was additionally performed. Results: From 59 198 patients with clavicle fractures, 341 (.6%) had concomitant ASVI. Compared to patients without ASVI, patients with ASVI had a higher median injury severity score (24 vs. 17, P < .001) and rates of pulmonary contusions (43.4% vs. 37.7%, P = .029) and BPI (18.2% vs. .4%, P < .001). After controlling for associated chest wall injuries and humerus fracture, the BPI odds ratio (OR 49.17, 35.59-67.92, P < .001) was independently associated with risk for ASVI. In a subset analysis of isolated clavicle fractures, BPI remained associated with risk of ASVI (OR 60.01, confidence intervals 25.29-142.39, P < .001). Conclusion: The rate of concomitant ASVI in patients with a clavicle fracture is <1%. Patients presenting with a clavicle fracture had a high rate of injuries including pulmonary contusion. Patients with findings suggestive of underlying BPI had a nearly 50 times increased associated risk of ASVI. Thus, a detailed physical exam in this setting including brachial-brachial index appears warranted.
