Identify the nerves
Hi! try to identify the three nerves shown in this image from Netter's atlas. Which one of these nerves will be damaged in 'Inferior Dislocation of Shoulder' or 'Surgical Neck Fracture of Humerus'?
The axillary nerve, exiting axillary fossa posteriorly passing thru quardrangular space together with posterior circumflex humeral artery, which winds around the surgical neck of humerus deep to deltoid =)
1. Suprascapular nerve which innervates the supra and infraspinatus muscles 2. Radial nerve in the triangular interval which courses along the radial groove of humerus to supply forearm extensors (+triceps)

ReplyDeleteCorrect what about the other nerve in the picture--Dr Nilesh
