SPECIAL INJURIES OF BONES. 34 1 



organized, or the inflammation may attack the bone, leading to 

 Ulceration and bony deposits. Similar bony deposits witn or 

 without ulceration may take place on these small bones in 

 connexion with injuries of the suspensory ligament 



Treatment. — Simple wind-galls, dropsical or from over-exer- 

 tion, may be made to disappear by persistent pressure with a 

 bandage and pads applied at first two hours twice a day, and 

 two hours more every day thereafter, until they can be kept on 

 all the time. It may, however, require five or six weeks, and 

 should be stopped if it causes inflammation in the sac. Another 

 plan is to draw off" the liquid through the nozzle of a hypo- 

 dermic syringe and apply a firm wet bandage. In some quiet 

 animals a weak solution of iodine may be injected, but this is 

 too often injurious or at least fruitless, from the irritability of 

 the horse. Recent puffs will sometimes disappear under strong 

 astringent lotions (oak-bark and alum), or under an active 

 blister, or after firing, the contraction of the skin during healing 

 appearing to be a principal cause of their absorption. 



Where there is sprain with much heat, tenderness, and 

 tension, treat by rest, purgative, a high-heeled shoe, and fomen- 

 tations or cooling astringent lotions, to be followed by blisters 

 when the tenderness subsides. 



Disease of the bones {Sesa?noiditis) must be treated with 

 severe blisters and even firing, with long continued rest, but if 

 ulcers aheady exist on the gliding surface of the bones a com- 

 plete recovery need scarcely be looked for. 



SPRAIN OF THE INFERIOR SESAMOID LIGAMENTS. 



The ligaments below these pulley-shaped bones behind the 

 fetlock are sometimes sprained, causing great lameness with 

 swelling and tenderness below the fetlock pad. Treat as f'x 

 injury to the suspensory ligament 



ELASTIC SWELLING IN FRONT OF THE FETLOCK. 



These are of two kinds : u/, a serous abscess or enlarged
