About _ninety percent of all cases of open joint make complete recoveries_, about four per cent partially recover and six per cent are fatal. Among the fatal cases are the open joints with complications as severed tendons, those occasioned by calk wounds in horses that are stabled, and nail punctures of the feet. The following report of twelve favorable cases is taken from a record of sixty-two cases. The favorable ones are reported, chiefly because there are now enough reports on record of such cases which have terminated fatally. Case 1.--A gray gelding used as a saddle pony received a horizontal wire cut laying completely bare the scapulohumeral articulation. The margins of the wound were cleansed as heretofore described, a drainage was provided surgically, tincture of iodin was injected and the wound was covered with equal parts of boric acid and exsiccated alum. The horse was kept tied and a diluted tincture of iodin was injected into the wound once daily and the powder applied often enough to keep the wound covered. The case made a complete recovery and the pony was again in service within sixty days. Case 2.--A twelve-hundred-pound bay mare with an open carpal joint. The wound was an open one about two and one-half inches in length, and made transversely and when the member was flexed the articular surface of the carpal bones were presented to view. An ounce of tincture of iodin was injected into this joint after having cleansed the margin of the wound and the mare was cross-tied in a single stall to keep her from lying down. The owner was instructed to keep the outside of the wound powdered with air slaked lime and a very unfavorable prognosis was given. I heard nothing further from this case until fifty-nine days from the date of the injury, when I met the owner driving this mare to a buggy. The wound had healed by first intention and at that time so little cicatrix remained that it was difficult to find it. Case 3.--A brown mare with an open fetlock joint due to a spike-nail puncture. Lameness was excessive, and joint greatly swollen. Tincture of iodin was injected into the wound and towels dipped in hot antiseptic solutions were applied for several hours daily until the acute stage had passed. Later the mare was turned out to pasture and a vesicant was applied once or twice a month until recovery was complete which was in about six months. Case 4.--A four-year-old bay mare having a wire-cut which opened the tarsus joint was treated as heretofore described. The wound was kept bandaged for about two weeks and later it was dressed without being bandaged. In ninety days she had completely recovered.
