204 SURGICAL AFFECTIONS. 



upward or downward. It loses its moljllity; can no longer be moved 

 about freely and in as many directions. Movements cause pain, and some 

 swelling occurs. 



To distinguish between fracture and dislocation is rarely difficult; In the 

 latter crepitus is absent, the bone can be moved less freely than natural, 

 while in fracture mobility is increased. If a broken bone is drawn Into 

 its proper shape and position the deformity then disappears, but returns 

 as soon as extension is discontinued ; when a dislocated bone is drawn 

 into place it will usually remain there. 



Wlien your dog has been injured, and the symptoms of fracture or dis- 

 location are apparent or suspected, seek the aid of a surgeon as you would 

 do had an accident of equal severity befallen any other near and dear 

 friend.
