PRINCIPLES OF VETERINARY SURGERY 87 



rather suddenly the muscle regeneration will begin and then 

 continue until completely restored to the normal size. In 

 crural paralysis of azoturia it does not matter how much 

 local or systemic treatment is given, the atrophy will persist 

 until a certain time (which is often as long as seven to nine 

 months) and then, (the nerve function being restored) the 

 muscles will show a decided tendency to "fill up" vacant ex- 

 cavation. 



In atrophy from inactivity of local muscles due to lame- 

 ness, the cause must first be removed before there is any pos- 

 sible help for the shrunken muscles. Exercise is the best rem- 

 edy. In very lame animals the paddock, the pasture and the 

 loose box are preventives of no small value. External appli- 

 cations to muscles wasted from this cause are ineffectual, 

 and only add more torture to the sufifering animal. 



Pressure atrophy is corrected by removing the pressing- 

 object, tumor, collar or whatever it may be.
