USE OF TWO-DIMENSIONAL REAL-TIME ULTRASONOGRAPHY FOR DIAGNOSING CONTRACTURE AND STRAIN OF THE INFRASPINATUS MUSCLE IN A DOG

: A strain injury to the infraspinatus muscle was a potential cause of forelimb lameness in a dog. Ultrasonography was used for evaluation of infraspinatus muscle injury. The ultrasonographic appearance of a typical infraspinatus muscle, contracture of an infraspinatus muscle, acute strain of an infraspinatus muscle, and progression of healing of the infraspinatus muscle are described.
