    Distal radial n.
  15. Loss of sensation on back of hand indicates...

    Proximal median n. injury (fracture of supracondylar humerus)
  18. Ulnar deviation upon wrist flexion
    Distal median nerve lesion (carpal tunnel, dislocation of lunate)
  19. Radial deviation upon wrist flexion
    Proximal lesion of the ulnar nerve (fracture of medial epicondyle of humerus)
