| pubmed-article:6383679 | pubmed:abstractText | Proximal humeral fractures are commonly seen in orthopedic practice. The vast majority of these fractures are nondisplaced. Infrequently, displaced proximal humeral fractures have associated neurovascular injuries. Injury to the brachial plexus is uncommon; axillary artery injury is rare. This is a report of two displaced proximal humeral fractures in elderly, intoxicated patients following low-energy trauma. Both fractures resulted in axillary artery injury requiring vascular reconstruction. Only nine similar cases were found in a review of the literature. Displaced proximal humeral fractures should be carefully evaluated for vascular injury, and arteriography should be used when necessary. If vascular reconstruction is indicated, the fracture must be internally fixed to prevent redisplacement and potential compromise of the vascular repair. Serial postoperative Doppler examinations are necessary to detect thrombus formation. With prompt diagnosis and treatment, prolonged limb ischemia and its sequelae can be prevented. | lld:pubmed |
