Atraumatic rupture of the gastrocnemius muscle after corticosteroid administration in a dog

Abstract

One deleterious effect of excessive use of corticosteroids on muscle and connective tissue is degenerative myopathy. Clinical manifestations of steroid-induced myopathy include a stilted gait and muscle weakness, usually affecting the hind limbs initially and progressing to generalized muscle weakness. Clinical signs of myopathy most often develop with use of triamcinolone acetonide.
