The supinator longusand extensor carpi radialis longior are usually affected, but sometimesescape when the nerve is injured below the origin of the branches tothese muscles. Fig. Wrist-drop from paralysis of the rousculo-spiral nerve (Leube). There is loss of power in extending the wrist and fingers and inextending the arm when the lesion is high up, owing to paralysis of thetriceps. The power of flexion of the hand is much diminished, owingto the loss of support of the extensors. In severe cases wasting of the muscles takes place, and a prominenceon the back of the hand develops, owing to protrusion of the synovialsacs and perhaps of the metacarpal bones. Sensation even in severe cases of paralysis is seldom much affected—a fact which is explained by the theory of vicarious sensation, theskin supplied by the radial being innervated by other nerves : althoughsome loss of sensation is at times experienced over the radial side ofthe back of the hand and fingers and the ball of the thumb, it is morecommon to find various forms of parsesthesise. From lead paralysis the distinction is made by the history of a cause,such as sleep or crutch palsy, by the more rapid
