Others are obtained from elderlypatients who have received the fracture in the usual manner, that is,by a fall upon the ground while walking, and have then died in a fewdays of an intercurrent affection, usually pneumonia. The Rontgen rays have recently added to our knowledge of thedetails, showing that the surface of fracture is rarely flat and trans- FiG.

They confirm the opinion that the radial sideof the bone is shortened and show that the carpus preserves its relationswith the articular surface of the radius, passing slightly upward towardthe radial side of the ulna and thus making the latter prominent. Inmarked backward displacement the ulna accompanies the fragment. The figures and Plates show the different levels atwhich the fracture occurs, the frequency and character of the comminu-tion, the difference in dorsal displacement, and the marked dorsal pro- FRACTURES OF THE BONES OF THE FOREARM. 315 jection of the first row of the carpus in one.
