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

Background<\/strong>: Radial nerve originates from posterior cord of brachial plexus at axilla. It supplies extensor muscles of upper limb.<\/p>\n

Objectives<\/strong>: To\u00a0 know the variations in muscular branches of radial nerve in axilla and posterior compartment of arm.<\/p>\n

Methods<\/strong>: Dissection was done on 44 upper limbs from embalmed cadavers and 6\u00a0 upper limbs from embalmed dead fetuses\u00a0 in the Department of Anatomy, J J M Medical College, Davangere. Dissection of Radial nerve and its branches in the axilla and posterior compartment of the arm was carried out according to Cunningham\u2019s manual of practical anatomy.<\/p>\n

Results<\/strong>: The site of origin of nerve to long head of tricep (N-LHT) was axilla\u00a0 in 48 specimens (96%) and lower triangular space( LTS)\u00a0 in 2 specimens (4%). The site of origin of nerve to lateral head of tricep( N-LTHT) was radial groove(RG) in 49 specimens (98%) and lower triangular space(LTS)\u00a0 in 1 specimens\u00a0 (2%). The site of origin of nerve to medial head of tricep -ulnar collateral nerve(UCN) was axilla\u00a0 in 38 specimens (76%) and lower triangular space(LTS)\u00a0 in 12 specimens\u00a0 (24%). The site of origin of nerve to medial head of tricep-nerve to anconeus(NA) was radial groove(RG)\u00a0 in 49 specimens (98%) and lower triangular space(LTS)\u00a0 in 1 specimens\u00a0 (2%). The additional branches to long head of tricep(LHT) was found in 20 specimens (40%). The additional branches to lateral head of tricep( LTHT) was found in 10 specimens (20%). \u00a0The additional branches to medial head of tricep(MHT) was found in 7 specimens (14%).<\/p>\n

Interpretation and Conclusion<\/strong>: The present study is important for Surgeons, Orthopedicians, and Neurophysicians as it provides the knowledge of variations in\u00a0 muscular branches of radial nerve in axilla and posterior compartment of arm to prevent possible complications.<\/p>\n

Key words<\/strong>: Radial Nerve, Triceps, Radial Groove. Wrist Drop.<\/p>\n
