The correct answer is: Radial

The radial nerve and the deep brachial vessels spiral around the shaft of the humerus in the radial groove. If the humerus is fractured, the radial nerve and the deep brachial vessels may be injured, since these structures are closely associated with the shaft of the humerus. The ulnar nerve passes posterior to the medial epicondyle of the humerus--a fracture to this epicondyle may injure the ulnar nerve. The axillary nerve wraps around the surgical head of the humerus-- a fracture near the surgical head may endanger the axillary nerve. The medial antebrachial cutaneous nerve and the median nerve travel superficially with the basilic vein and the brachial artery in a neurovascular bundle. These nerves are not going to be injured by a fracture of the humerus.
