94 Injuries of Bone. 



3. 137. United Colles' Fracture. — Eight radius and ulna of an 

 old woman — macerated, showing the above. 



The displacement is comparatively slight. The styloid 

 process of the radius is however slightly pushed upwards 

 towards the elbow, and the articular surface looks now directly 

 downwards in the axis of the bone, instead of, as normally, 

 forwards. G. C. 3221.

3. 138. United Colles' Fracture. — Left hand of an adult 



dissected to show the relations of the tendons at the wrist 

 after the above injury — in spirit. 



The deformity is characteristic. The tendon of the 

 extensor carpi ulnaris has been dislocated outwards, and lies 

 external to the head of the ulna. In every other respect the 

 tendons are in their normal position, and they are free from 

 adhesions. G. C. 3219.
