Abstract
Displaced Fracture of the Proximal Humerus Causing Axillary Artery Injury and Brachial Plexus Palsy
Highlights
The proximal axillary artery and brachial plexus are contained within the same fascial sheath and while this affords protection it may result in a brachial plexus palsy caused either by direct trauma from the fractured bone or due to oedema and/or compression from hematoma
We report a rare case of a severely displaced fracture of the proximal humeral shaft that caused blunt trauma to the axillary artery and brachial plexus palsy
Due to the proximal axillary artery and brachial plexus sharing the same fascial sheath once an axillary artery occurs there may be associated brachial plexus palsy [2]. This brachial plexus palsy is caused either by direct trauma from the fractured bone, which is commonly blunt in nature, or due to oedema and/or compression from hematoma [3,4].We report a rare case of an elderly female, whom after a simple fall, suffered a severely displaced fracture of the proximal humeral shaft that caused blunt trauma to the axillary artery and brachial plexus palsy
Summary
We report a case of an elderly female patient who slipped and fell at home. She presented to our unit complaining of left shoulder pain and an inability to feel or move the involved limb. Imaging studies confirmed the presence of a severely displaced fracture of the proximal humerus and occlusion of the axillary artery. She was taken for open reduction and internal fixation of the proximal humerus followed by immediate axillary artery endovascular stenting
