Your patient is a 50-year-old motorcyclist who received a lateral impact from an automobile as he went through an intersection. he has an open right tibia/fibula fracture. he also has a fracture of his left forearm and some abrasions. he was wearing a helmet and suffered no loss of consciousness. he currently has a strong radial pulse of 100, his skin is warm and moist, and he has adequate respirations at 20 per minute. assuming no significant findings during a rapid trauma exam and intact distal neurovascular status, what is the way to manage this patient's lower extremity trauma?
