. Common diseases of farm animals. Veterinary medicine. DISEASES OF THE HIND LIMB 181 sometimes advisable to repeat the counterirritatioii if the results of the first firing are unsatisfactory. Bog Spavin.—Bog spavin is an extensive distention of the capular ligament of the hock-joint by synovia (Fig. 48). It is geuerallv due to chronic inflammation of the synovial membrane. This blemish or unsoundness is most common in young horses. Thorough pin (Fig. 49) involves the sheath of the large tendon only. (Com- pare Figs. 48 and 49.) Certain conformations of the hock favor the develop- ment of bog spavin. This is especially true of upright and " fleshy " hocks. Hard work may cause the hocks to " fill " when followed by a brief period of rest. The common cause is a sprain due to slip- ping and pulling heavy loads. The following symptoms may be noted: Lameness is not a common symptom of bog spavin. If there is inflamma- tion present or the articula- tion is injured, lameness oc- curs. The soft swelling that characterizes the bog spavin is most prominent toward the inside and front of the region. In the upper portion or hollow of the hock, and on the inside and out- side, there may be a second enlargement. Smaller enlargements may be present in other regions. All of the swellings feel soft, and pressure on any one of them moves the fluid present in the Fig. 49.—Thorough pin. Note the relation of the enlargement to the tendon, and the free- dom of the hocks from bog Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Craig, Robert Alexander, 1872-.
