On February 2,1960, a one and one-half-year old registered Angus bull was admitted to Stange Memorial clinic. The history revealed that the animal seemed to drag the right foreleg. The clinical examination confirmed the dragging of the leg and a pronounced shoulder lameness was noticed. Atrophy of the supraspinatus and infraspinatus muscles was evident.
