This subject will be considered in two parts — open 

 joints of recent origin in fresh wounds, and those of a

 an articulation is involved in the trauma. While all 

 accidental wounds in veterinary patients are to be con- 

 sidered surgically unclean, it is well not to carry this 

 theory too far. Unless much extraneous matter, such 

 as hair, chaff, etc., has entered directly into the articula-

 synovial surfaces when you clean up such a wound. 



Swab the surroundings as clean as possible with a cot- 

 ton swab,, but do not aUow any of the solution to reach 

 the joint. Nothing seems to irritate a synovial joint 

 more than water. 



After the surrounding parts are thoroughly swabbed 

 and dried with clean, dry cotton, the wound cavity is 

 completely filled with chemically pure powdered sodium 

 bicarbonate, some of which is even gently pressed so as 

 to enter the synovial cavity. It is important that

 to cover the lesion and is retained either with col-
