344 SPRAINS OF TENDONS. 



essence and outward sign of the sprain under our notice, must be 

 distinguished from both bog-spavin and thorough-pin : to which it 

 can, indeed, have no relation, from the circumstance of those affec- 

 tions being either directly or indirectly connected with the cavity of 

 the hock-joint, with which this has no connexion whatever. It also 

 differs from those affections in being generally productive of lame- 

 ness. From curb, its situation will at once distinguish it. 



Its Treatment will consist in a high-heeled shoe being applied; 

 and in using fomentation and stimulant lotions; with the aid of 

 cathartic medicine and rest. As soon, however, as the inflamma- 

 tory symptoms have abated, even though lameness may have dis- 

 appeared, it will be advisable to blister the part before returning 

 the horse to his work. 



Sprain of the Tendon 

 OF THE Flexor Metacarpi Externus. 

 Now and then this accident occurs. It consists in an oblong 

 windgall-like tumour, making its appearance upon the outer side 

 of the arm, immediately above the knee, taking the course of the 

 tendon above-named, and consisting, evidently, in distention of the 

 sheath of that tendon, from an accumulation of fluid within it. 

 Some extraordinary and unprepared-for exertion has caused lesion 

 or strain of the parts; the fibres of the delicate cellular tissue 

 uniting the tendon with its sheath, 6r, may be, those of the sheath 

 itself, have sustained strain or laceration, and the result has been 

 effusion into the cavity of the sheath. On its first occurrence, the 

 horse commonly goes lame from the sprain, though the lameness 

 may be but slight. After a short time, however, under any ordi- 

 nary treatment, the lameness usually disappears : the tumour still 

 remaining; without causing any pain, however, or even incon- 

 venience to the animal in action. 



Sprain of the Tendon 

 OF the Flexor Metatarsi. • 



This being rather an unusual accident, and, when it does occur, 

 a serious one, and happening to have lately had an excellent case 

 of it, I prefer giving the particulars of the case as they stand in 

 my " Records" to offering any general observations on its nature.
