Symptoms.—Sores on back, withers, or shoulders are ordinarily due to recent swellings from blows or injuries of some kind.
Treatment.—Sulphate of zinc 4 drachms, cold water 1 quart; apply by washing or with wetted bandages. Or first cleanse a healthy sore with soap and water, then apply sulphur 3 parts, iodoform 1 part.
SPRAINS.
Sprains consist in an overstretching of a muscle, tendon, or ligament to such a degree as to rupture some of the fibres of which it is composed. They are divided into muscular sprains, tendonous sprains, and ligamentous sprains.
Muscular sprains usually occur in the powerful muscles of the loins and quarters; they are serious and often permanent injuries.
Tendonous sprains are the most common, and the flexor tendons of the fore legs are most frequently affected.
Ligamentous sprains are serious injuries, and may occur in any of the numerous ligaments belonging to the joints of the body. The principles of treatment are the same as for tendons.
Symptoms.—Sprains of tendons and ligaments are manifested by heat, swelling, pain on manipulation, and lameness.
Treatment.—First reduce the inflammation by rest and constant use of hot fomentations. If the sprain be severe and at the rear part of the fore or hind leg, raise the heel of the shoe on the affected leg an inch or more.
