436 CLINICAL VETERINARY MEDICINE AND SURGERY. 



The animal also had a large wound in the sheath, and a number of 

 contusions, none of which, however, were of much gravity. 



Treatment, — The parts were disinfected, and the lower angle of the 

 shoulder wound was laid open, to prevent discharge accumulating in 

 the above-mentioned cul-de-sac. Drains were inserted and warm 

 antiseptic solutions freely employed. An injection of antitetanic serum 

 was given. 



On the following days the wound suppurated, but its walls gradually 

 became covered with granulations. 



Drainage was continued until the 20th April. At that date the 

 wound near the elbow was half healed and reduced to five inches in 

 length. The shoulder wound also filled up rapidly, though the external 

 lip was strongly drawn inwards in the direction of the tract by cicatri- 

 cial contraction. To remedy this the skin covering the outer surface 

 of the wound was dissected free for a sufficient distance to allow of its 

 being brought into contact with the inner lip, to which it was united 

 by a few silk sutures. 



On the 23rd April the central part of the tract had filled up. The 

 animal left hospital on the i6th May. Healing was almost complete. 

 There was no lameness, or interference with movement. 



FOREIGN BODY IN THE KNEE. 



144. A four-year-old Gordon setter, entered hospital February 7th, 

 1899. 



Had suffered since the commencement of December from lameness, 

 the cause of which could not be traced. One morning the animal was 

 seen to be going lame on the left front leg and showed a small circular 

 wound on the knee. It was thought to have been injured by a fragment 

 of glass from one of the forcing-houses of a market-gardener, who lived 

 in the neighbourhood. No importance was attached to the accident. 

 In spite of the use of various topical applications and dressings, the 

 lameness persisted and grew more marked, the knee gradually becoming 

 swollen and painful. The dog was finally brought to Alfort two months 

 after the accident. 



State on Examination. — The animal walked on three legs. The left 

 fore-limb was flexed, and no weight could be borne on it. The knee, 

 the lower part of the forearm, and upper part of the metacarpus were 

 swollen, the posterior aspect of the knee especially being greatly 

 enlarged. The parts were so extremely sensitive that the animal 

 howled when they were lightly touched, or when an attempt was made 

 to extend the metacarpus on the forearm. There was trifling traumatic 

 fever. Temperature 38*9° C. 



After clipping the hair from the swollen region a circular wound, 

 and two narrow sinuous openings, from which blood-stained pus escaped, 

 were discovered, opposite the centre of the knee; one was situated on 

 the external surface, near the flexure of the joint ; the other at the 

 anterior part of the external surface. 



These symptoms and the long-standing character of the disease, 

 led us to suspect necrosis of bone or tendon, or the presence of a
