A two-day old male Jersey calf was presented to the Large Animal Clinic at the Veterinary Teaching Hospital of UFSM. The history included constant flexion of both anterior fetlocks and impossibility of standing up. A conservative treatment with PVC casts was installed. Casts were changed every 72 hours and their angle readjusted. The animal presented labored breathing with audible stridor, principally during and immediately after nursing. At the 28th day of treatment the calf suffered luxation of the right coxofemoral joint. Forty-eight hours later, the left side also was displaced. Due to the bilateral luxation and the increasing respiratory distress the animal was euthanatized on the 33rd day of treatment. At necropsy, in the heart was observed patency of the foramen ovale and ductus arteriosus. The trachea had a luminal constriction with significant reduction of internal diameter on the initial four segments. The coxal fossa on both sides were considerably shallow.
