John PY - 2017 T2 - Tintinalli's Emergency Medicine Manual, 8e AB - The hand is innervated by the median, ulnar, and radial nerves. Motor function of the median nerve can be screened by flexing the thumb distal phalanx against resistance, the ulnar nerve by spreading the fingers against resistance, and the radial nerve by maintaining extension of the finger MCP joints against resistance. Sensory innervation (Fig. 170-1) is best screened by the presence of normal two-point discrimination (<5 mm). Injuries requiring hand surgery consultation are listed in Tables 170-1 and 170-2.
