While jogging in a park, a 45-year-old man tripped and fell on his outstretched hand. As he fell, he tried to catch himself on a nearby park bench but was unsuccessful. He felt that his shoulder was out of place, and he was unable to adduct his arm from its erect position. A witness called for an ambulance, and the man was taken to the emergency department.
