Brachial plexus injury and upper rib fracture after median sternotomy in cardiac surgery.
ABSTRACT
OBJECTIVES
Sternal retractors utilized during open-heart surgeries through median sternotomy can cause upper rib fractures which sometimes further leads to brachial plexus injury. We aimed to investigate the incidence of brachial plexus injury and upper rib fractures in open-heart surgeries and how these injuries are associated with each other.
METHODS
We investigated 1050 cases during the past five years. The incidence of brachial plexus injury and upper rib fractures after median sternotomy was assessed in all patients and the patients who sustained were evaluated for the affected side, the level of paralysis.
RESULTS
Ten cases (0.95%) exhibited brachial plexus injury after median sternotomy. Nine cases developed paralysis on left upper extremity. In all ten cases, sensory and motor nerve impairment were exhibited in the lower plexus. Rib fractures were observed in 35.0% of cases after median sternotomy and the usage of asymmetric sternal retractors to harvest left internal thoracic artery (LITA) significantly affected the side of fracture.
CONCLUSION
Sternal retractors utilized during open-heart surgeries through median sternotomy may cause rib fractures and brachial plexus injury, so operators should be aware of these complications.

Brachial plexopathy after median sternotomy is not very common. Its frequency varies in different studies but it's most likely between 0.5-5%. The most likely mechanism is tra...
