Abstract
Proximal humerus fractures are common injuries and represent approximately 5% of all fractures.10, 14, 21 These fractures are infrequently associated with neurovascular injuries. Brachial plexus injuries are uncommon,18 whereas axillary artery injuries are rare.5–9, 11, 12, 16–20, 22–24 A review of 19 previously reported cases of axillary artery injury after proximal humerus fracture revealed that 84% occurred in patients older than 50 years, 53% were associated with brachial plexus injury, and 21% resulted in upper extremity amputation. This study describes a case of axillary artery injury after proximal humerus fracture and, on the basis of a literature review, offers suggestions for the early diagnosis and effective treatment of this uncommon injury.
