What are the symptoms of a purulent bursitis ? 



There is decided s-welling, septic cellulitis of the para- 

 bursal tissue, with a discharge of pus. 



Outline the treatment of purulent hursitis. 



Split the swelling from the center downward and intro- 

 duce tampons saturated with a two to three per cent, chloride 

 of zinc solution for two to three days ; after that employ anti- 

 septic irrigations. I have had splendid results in the treatment 

 of capped elbow by making a regular sieve out of the swell- 

 ing by running the finest platinum point of the thermocautery 

 through the skin deeply into the infiltrated parabursal tissue, 

 having the holes made by the red hot point about three- 

 quarters of an inch apart. 



Chronic Dropsy of the Mucous Bursa. 



What are the causes of hygroma of mucous bu/rsa ? 



When the serous or serofibrinous fluid in the bursa is not 

 absorbed a chronic bursitis results. When now mechanical 

 irritations, such as pressure from a shoe or kicking, etc., are 

 allowed to continuously act upon the chronically diseased 

 bursa, a hygroma or chronic dropsy of the bursa is the result.. 



What changes take place in the bursa before it becomes a 

 hygroma ? 



The walls of the bursa and the parabursal tissue undergo 

 chronic fibrous changes leading to more or less extensive 

 thickening and induration of the walls, forming a firm con- 

 nective tissue capsule. 



JPathologically speaking, what process takes place ? 



A chronic fibrous bursitis and chronic parabursitis.
