SPAVIN, 

 (see plate II.) 



Synonym, — Bone spavin. 



Definition. — Spavin is an exostosis in the region of the hock. (See 

 Fig. 84.) It is usually found to involve two or more of the weight- 

 bearing bones. It generally appears on the inner side of the hock, rarely 

 on the outer side. Bog spavin, though somewhat similar in name, and 

 also occurring in the hock, has no connection with this disease. 



Spavins, which Avhen fully formed do not cause lameness, should 

 never be subjected to active treatment. Treatment in such cases, in- 

 stead of being advantageous, is very likely to renew the inflammation, 

 which may perhaps produce further growth of bone and eventually 

 lameness. 



A spavin, when once fully formed, cannot be removed by any reme- 

 dial agents, though, in common with all abnormal growths, exostosis 

 generally becomes less as age advances. 



Etiology. — The common causes are undue concussion, pressure.
