Rare finding of axillary artery dissection secondary to a proximal humerus fracture-dislocation: A case report

Abstract

Case: Proximal humerus fractures are a relatively common injury, making up approximately 5 % of all extremity fractures. Concurrent damage to the axillary artery, however, is not a commonly associated trauma. We present a unique case of a proximal humerus fracture-dislocation resulting in an axillary artery dissection and upper extremity ischemia, requiring emergent vascular intervention. Conclusion: Axillary artery injury secondary to a proximal humerus fracture-dislocation is a rare, but possibly devastating complication. A thorough physical examination to identify any neurovascular deficits is critical in determining an optimal and timely resolution.
