Occasionally the lower fragment is displaced forwardsin consequence of falls on the back of the hand. Comminu-tion of the lower fragment with involvement of the wrist jointfrequently occurs. Signs.—Very characteristic. On the back ofthe wrist, just above the joint, there is a prominence caused bythe backwardly displaced lower fragment, and above this a slightdepression; whilst on the palmar surface there is a prominencecaused by the lower end of the upper fragment, corresponding tothe dorsal depression, and below this a depression corresponding Fig. 171.
