ABSTRACT<\/strong><\/p>\n

Background<\/strong>: Axillary nerve, one of the terminal branches of posterior cord of brachial plexus is more prone for iatrogenic injuries. Lack of proper anatomical knowledge and variations of axillary nerve leads to an increased risk of nerve injuries. The present study describes the origin of axillary nerve, its distance of origin from anteromedial aspect of coracoid process, posterolateral aspect of acromion process, and its termination.<\/p>\n

Material and<\/strong> Methods:<\/strong> 50 brachial plexuses from 25 adult embalmed human cadavers of both the sexes were studied by dissection method at the Department of Anatomy, MVJ Medical College, Bangalore.<\/p>\n

Results:<\/strong> In 41(82%) specimens, axillary nerve originated from the posterior cord of brachial plexus and in\u00a0\u00a0 9(18%) specimens axillary nerve originated as a common trunk along with thoracodorsal & lower subscapular or thoracodorsal, upper & lower subscapular, or only with lower subscapular nerve from the posterior cord of brachial plexus. The mean distance of origin of axillary nerve from the anteromedial aspect of coracoid process and posterolateral aspect of acromion process is 3.67cm & 6.43cm respectively. The axillary nerve terminated into anterior and posterior divisions within quadrangular space in all the specimens.<\/p>\n

Conclusion:<\/strong>\u00a0 Knowledge of variations of axillary nerve is of immense significance to clinicians, anaesthetists and orthopaedic surgeons during surgical exploration of neck, axilla and upper arm, fracture of surgical neck of humerus, shoulder dislocation and infraclavicular brachial plexus block.<\/p>\n

Key words<\/strong>: Axillary nerve, Acromion process, Coracoid process, Thoracodorsal, Lower subscapular.<\/p>\n
