332 SYNOVIAL ENLAKGEMENTS. 



antiseptic solution (p. 67), dress the wound with, tannoform or 

 iodoform, cover it with two or three thicknesses of antiseptic 

 wool, and then apply a firm cotton wadding bandage (p. 45) over 

 the part. The object of the band'age is to cause the walls of the 

 sac to unite together. 



Capped Withers 



is an enlarged condition, as a result of inflammation from injury, 

 of the synovial bursa which lies on the top of the withers. It 

 may be distinguished from an abscess by its being soft and mov- 

 able, 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 difference 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 appears as a tense fluctuating 

 swelling, situated on both sides of the point of the hock " (Wil~ 

 hams). 'The rigidity of the tendon prevents the swelling project- 

 ing backwards. This not very common affection is, undoubtedly, 

 an unsoundness. It may be caused by sprain of the tendon, or 

 by blows. Treatment consists in giving rest, using massage (p. 

 664), and apjjlying 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 form of capped hock, 

 see next chapter.
