Oily preparations of iodine may also be used to anoint the arms of the surgeon during the handling of infected cases of obstetrics. Pouring a quantity of the preparation into the palm of the hand, and then rubbing it gently over the skin of both hands and arms, proves a reliable barrier to infection from a decomposed fetus or after-birth. In applying the oily preparations of iodine, to lesions on the integument, it is always necessary to massage them into the tissues quite vigorously; when this is done a single application each day suffices. Other indications for the oily preparations, as well as for aqueous preparations, of iodine, have been pointed out in the chapter devoted to the selection of iodine preparations for practical use. Ointments of iodine--which, for me, mean Iodex--have, by far, the most extensive field of application, and the uses to which an iodine ointment may be put have already been quite clearly indicated. I will, however, remark some of the points to be considered in using Iodex in such cases as spavin lameness and similar affections of the articulations. In choosing, for treatment with Iodex, a case of spavin lameness, the practitioner should select only those cases in which the horse warms out of the lameness; these cases can positively be cured by Iodex applications. Do not attempt to cure the lameness caused by spavin in which the horse will not warm out of the lameness; these cases are not only impossible of cure by this means but by other means, excepting neurectomy, as well. When the case has been selected, the Iodex should be applied, not only in the immediate vicinity of the exostosis, but entirely around the hock involved. An application should be made every morning and every evening, in the following manner: Apply a thin coating of Iodex and massage it into the hock for at least five minutes; then apply another very thin coating, allowing this to remain on the surface. The applications must extend over a period of from five to seven weeks--about such a length of time as is required to effect a cure with actual cautery--and, during the first few weeks of this period, the animal should be at rest. After the second week, it may indulge in light exercise in a lot or paddock, but may not be worked. Cases of spavin, treated in this manner--cases selected for treatment as above outlined--are not only cured of lameness, but, in many cases, the enlargement also disappears. The same results are obtained in cases of lameness from ringbone, sidebone, splint and curb. Buck shins can be entirely absorbed with applications of Iodex as directed above. Other conditions, in which the effects of Iodex frequently are most remarkably satisfactory, are goitre, fibrous tumors on the body surface, hygroma, and tendonous and ligamentous enlargements. The applications, in these conditions, are made in a manner similar to that in spavin, massaging the Iodex thoroughly into the parts involved.
