330 SYNOVIAL ENLARGEMENTS. 



Capped Withers. 



This is an enlarged condition of the synovial bursa which lies on 

 the top of the withers, as a result of inflammation from injury. 

 It may be distinguished from an abscess by its being soft and 

 movable, without any tendency to " pit " on pressure, and without 

 its being surrounded by a hard zone of inflamed tissue. It feels 

 less hot to the touch than a recent abscess near the withers, and 

 pursues a much slower course. We should apply to it the same 

 treatment as that for capped knee (see preceding paragraph) ; 

 allowing for difierence of position. 



Synovial Capped Hock. 



This form of capped hock is due to enlargement of the synovial 

 bursa which is placed between the point of the hock and the tendon 

 that is attached to that bone. It appeals as a tense fluctuating- 

 swelling, situated on both sides of the point of the hock. The 

 rigidity of the tendon prevents the swelling projecting backwards. 

 This not very common affection is, undoubtedly, an unsoundness. 

 It may be caused by sprain of the tendon, or by blows. Treat- 

 ment consists in giving rest, using massage (p. 675), and applying 

 a high-heeled shoe. Blistering or firing may be tried in cases 

 which do not yield to milder measures. 



For the more common, though less serious forni of capped hock, 

 see next chapter.
