INJURY TO THE BRACHIAL-PLEXUS BY A FRAGMENT OF BONE AFTER FRACTURE OFTHE CLAVICLE

Clavicular fractures are occasionally responsible for lesions of the b rachial plexus. The symptoms are usually delayed and due to compressio n by hypertrophic callus, nonunion or a subclavian pseudoaneurysm. We describe a patient in whom a displaced bone fragment was pressing on t he retroclavicular part of the brachial plexus, leading to early sympt oms of a lesion of the posterior cord, Internal fixation of the clavic le and external neurolysis of the brachial plexus gave an almost full recovery.
