WHERE ARE SYMPTOMS OF MEDIAN NERVE COMPRESSION MOST LIKELY TO BE FOUND?
A. The dorsal surface of the thumb. B. The palmar surface of the little finger. C. The dorsal surface of the middle finger. D. The palmar surface of the index finger. THE CONSULTANT’S CHOICE The median nerve innervates the palmar surface of the index finger (D), thumb, middle finger, and half of the ring finger, along with the tips of the thumb, index finger, and middle finger—and half the tip of the ring finger. The dorsal surface of the thumb (A), except for the tip, is innervated by the radial nerve. The palmar surface of the little finger (B) is innervated by the ulnar nerve. The dorsal surface of the middle finger (C) is innervated by the radial nerve. In a patient with suspected carpal tunnel syndrome, the physical examination focuses on assessment of the sensory and motor functions of the median nerve. First, observe the palms of both hands and compare the thenar area of the injured hand with that of the non-injured hand to check for atrophy. Although lack of atrophy does not ru
