A rather common farm accident with a horse-drawn mower, brought a young roan Belgian mare to the Stange Memorial Clinic on July 20, 1943, with severed superficial and deep flexor tendons of the left hind leg. The gaping wound was inflicted between the middle and distal third of the metatarsus. The horse placed considerable weight on the leg, allowing the fetlock to touch the ground at times.
