The broad tendon of the extensor carpi radialis longior, which is insertedinto the second metacarpal bone, appears upon the ulnar side. The artery has previouslygiven off the common digital branch for the forefinger and thumb, which may readilybe mistaken for the main trunk. 216. Radial Artery upon Trapezium (Fig. 138).

The vesselcan here be felt through the skin. In the subcutaneous tissue parallel to the tendonsare the radial vein and nerve, which are to be avoided; the latter can be felt uponthe outer side of the radius. The artery courses obliquely beneath the above-mentionedstructures upon the scaphoid and external lateral ligament. 217. Dorsal Branch of the Ulnar Nerve (Fig. 137). The nerve may be distinctlyfelt upon the ulnar side of the unciform bone. It is exposed by a longitudinalincision extending from the lower end of the ulna downwards along the ulnar edge ofthe carpus. It lies either upon or in the fascia, after having passed backwardsfrom the forearm under the flexor carpi ulnaris. 218. Radial Nerve (Fig. 138). This nerve may be exposed by the same
