PREVENTION, SYMPTOMS AND TREATMENT 2z| e 



ing more common. It results in recovery, or in fibrous thickening 

 (plastic form), or in chronic teno-synovitis (hygrops, hygroma). 

 In the suppurative form there is great lameness, fever, spreading, 

 tender, edematous swelling along the course of a tendon and often 

 abscess. The traumatic acute form is separated from the infectious 

 by being confined to one area and in not shifting to other sites. 

 Tuberculous teno-synovitis is seen in cattle along the front of the 

 forearm and knee (extensor metacarpi and long extensor of the 

 toe). A hot, tender, diffuse swelling exists, causing lameness, 

 atrophy of the shoulder muscles, and is accompanied by general 

 wasting. The swelling is usually of a fibrous nature and crepita- 

 tion may be evident. It cannot be distinguished from non-tuber- 

 culous disease except by bacteriological examination and inoculation. 



Treatment. — In acute serous teno-synovitis the animal should 

 be given complete rest, and, externally, moist heat and pressure 

 should be applied — as by a moist antiseptic dressing (gauze soaked 

 in 2 per cent, creolin) covered with rubber or oil silk and a flannel 

 bandage. Cold applications, as compresses constantly wet with 

 cold water, are also efficient but are not so readily employed nor 

 any better. Bandages wet with white lotion (lead acetate and zinc 

 sulphate, each 3iii; water Oi) are of benefit. Later on, after the 

 acute stage passes, one may apply tincture of iodine every few days, 

 or iodine ointment, and use massage and pressure with bandage, 

 and gentle exercise. Neither firing and blistering nor operative in- 

 terference are called for. 



If the acute serous synovitis is of infectious origin, particularly 

 in acute articular rheumatism, treatment with sodium salicylate 

 and sodium bicarbonate (of each 3iv, thrice daily in drench) is of 

 much service. 



Suppurative teno-synovitis, in its early stages, may be treated 

 by wet antiseptic poultices (2 per cent, creolin on aseptic gauze) 

 covered with water-proof material and bandage. It is probable that 

 Bier's hyperemia is the best treatment (see p. 278). But, with the
