    BackgroundFracture and dislocation of the proximal humerus is common. It is associated with a number of vascular, neurologic, and orthopedic complications; these include brachial plexopathy and avascular necrosis (AVN) of the humeral head. These complications are rare but can potentially cause severe disability to patients; however, they remain poorly described in the literature. To describe vascular, orthopedic, and neurologic outcomes after axillary artery repair, in patients with proximal humeral fractures or dislocations.MethodsWe conducted a retrospective review of patients admitted to 2 tertiary trauma centers in Victoria, Australia, with fracture or dislocation of the proximal humerus and associated axillary artery injury. Patients were selected according to guidelines for trauma call or alert and the presence of high-risk mechanism of injury. Data on vascular, orthopedic, and neurologic complications were collected.ResultsTwenty-one patients were identified. Injury to the first part of the axillary artery was noted in 11 patients (52%). Brachial plexus exploration was performed in 17 patients (81%). Four patients (19%) underwent nerve repair. Long-term neurologic recovery was universally poor. Major orthopedic complications included AVN of the humeral head, delayed union, and the need for prosthesis or arthrodesis. Eleven patients (52%) received upper limb fasciotomy. Five patients (24%) underwent delayed secondary upper limb amputation.ConclusionsThere was an unusually high rate of injuries to the first part of the axillary artery. Close clinical observation is recommended for such patients. AVN of the humeral head and brachial plexopathy remain significant and debilitating complications.Copyright © 2016 Elsevier Inc.
