title: Accessory Upper Subscapular Nerve - The Neurotisation Tool.
abstract: During the routine dissection classes for undergraduate students, uncommon variation in relation to the upper subscapular nerve of posterior cord of brachial plexus was observed. Normally upper subscapular nerve takes origin from the posterior cord, but in this case report, it arises in triplet fashion, just above the circumflex scapular artery. All these accessory nerves were supplying upper part of the subscapularis muscle. As per our knowledge, this is a rare variation of brachial plexus. Many variations are encountered in the formation of brachial plexus. The normal and the abnormal origin of nerves are important considering neurotisation surgeries as well as during the infraclavicular nerve block for various axillary and upper limb surgeries.
