Successful medical management and rehabilitation of exercise-induced dorsal scapular luxation in an ultramarathon endurance sled dog with magnetic resonance imaging diagnosis of grade II serratus ventralis strain.

Dorsal displacement of the scapula in dogs is rare and often traumatic. This report describes dorsal luxation of the scapula in a sled dog. This case is unique given the injury was sport-related. Magnetic resonance imaging helped direct therapy and monitor healing; and medical management with rehabilitation resulted in full recovery and return to sport. One year after injury, the dog completed both a 482 km and a 1600 km endurance race, placing among the leading teams in the 1600-km race.
