[Axillary nerve injury associated with shoulder dislocation: case report].

Isolated lesion of the axillary (or circumflex) nerve is infrequent, this is usually associated with a brachial plexus injury. In our institution, in a period comprised between the years 2015-2017, a frequency of only 0.4% of this injury has been observed. Clinical case: Male patient of 31 years of age, with trauma in the right shoulder, caused by fall of his own height in work accident. The admission graph of the right shoulder shows anterior inferior dislocation of the glenohumeral joint, associated with a greater tubercle fracture. He underwent surgery, with closed reduction of the glenohumeral joint and osteosynthesis of the greater tubercle. The patient later presents marked atrophy of the deltoid, electromyography is ordered that shows complete lesion of the axillary nerve without reinnervation.
