When inflammatory action has commenced in a bursa, it must be subdued by copious topical bleeding, along with the exhibition of purgatives; in most cases general bloodletting will not be required. After the inflammation has subsided, the parts remain swollen, from the effusion either of serum or lymph; stimulating applications may then be employed with advantage. In general, the ammoniacal plaster, or the brushing over the surface with tincture of iodine will answer. Blisters are sometimes employed with the same view. In obstinate cases, when the tumour is of no large size, a seton may be passed, retained till suppuration has taken place, and gradually withdrawn. Great risk attends interference with bursæ of large size near joints or cysts containing serous or glairy fluid in any situation. Even trifling punctures into such have been sometimes followed by inflammation of the inner secreting surface and violent constitutional disturbance. When suppuration has occurred, it will in many instances be prudent to evacuate the matter by one or more incisions, in order to prevent farther mischief, especially if the bursa, a superficial one, is in the neighbourhood of a joint. After the matter has been evacuated, the cavity gradually contracts, and ultimately the bursa is completely obliterated. Diseased bursæ, near the surface, and unconnected with important parts, have been dissected out. The operation is not often necessary, and in some situations attended with considerable risk. Tumours, solid or nearly so, arising from diseased bursa of long standing, may sometimes require to be so treated. OF COXALGIA, MORBUS COXARIUS, OR HIP-JOINT DISEASE.
