A 6-year-old Angus cow was admitted to Stange Memorial Clinic on December 28, 1955. The animal was suffering from a myositis with calcification in the left front leg. The carpus was fixed in complete flexion, rendering the limb entirely useless. The animal also had a vaginal prolapse which had been caused by the lunging gait and the tremendous muscular exertion needed to rise.
