FRACTURE OF TRAPEZIUM. 315 



occurs, there is often no displacement ; hence, horse owners should 

 make it a rigid rule, that if one of their animals gets kicked on the 

 inside of a hind leg, just above the hock, he should not be worked 

 until all fe^ar of a fracture is removed. A thickening of the bone 

 over the seat of injury will indicate, after a few days, the existence 

 of reparative action. The person treating the case should on no 

 account, when making his examination, work the parts about, lest 

 he may cause displacement. The animal should be put into slings, 

 or " tied up," so that he may not lie down ; for if fracture without 

 displacement exists, it will almost certainly be converted into a 

 compound one on the horse endeavouring to get up, after he has 

 lain down. The animal should be put in slings, and an immovable 

 bandage (p. 298) applied to the limb, from the fetlook, to as high 

 up on the leg as it can go. Splints may be applied over this, with 

 an adhesive bandage to keep them in position. Many oases of com- 

 pound fracture of the tibia can be cured in this manner ; after, of 

 course, setting the bones in position, in the first instance. 



Trapezium. 



Mr. James McKenny relates a case of fracture of this bone 

 (Fig. 8, p. 35), caused by the horse coming down with the 

 back of its knees on stiff timber, over which it was being lunged. 

 The animal recovered sufficiently to walk sound, but not to stand 

 fast work. The injury is manifested by swelling, pain and 

 crepitus of the part, and '"dropped elbow" (p. 313) of that side.
