Intra-articular corticosteroid treatment of biceps tenosynovitis in a dog

A 3-year-old, 35 kg, neutered male Borzoi was admitted with a history of intermittent weight-bearing left forelimb lameness. Physical examination revealed pain response on left bicipital tendon during palpation of the tendon and shoulder flexion and extension. Radiographic findings of the left shoulder joint included intertubercular groove osteophytes and periarticular changes. Arthrograms revealed a roughened and irregular appearance to the biceps tendon. Synovial fluid analysis is consistent with degenerated joint disease. It was diagnosed as biceps tenosynovitis on the basis of history, physical examination, radiography and arthrograms. The dog was treated with medical management. Medical treatment included an aseptic intra-articular injection of 40 mg methylprednisolone acetate in the left shoulder and strict exercise restriction. Three weeks later, the dog responded well to glucocorticoid therapy.
