Q. A 28-year-old woman was brought to the emergency department following a pedestrian-car accident about 2 hours ago. She is alert (GCS 15) but is in severe pain. Besides some abrasions over her face and hands, the only injury is in her left leg. It is immobilized in a compression brace and has severe edema. She has no significant medical history and takes no medications. After removing the immobilizer, the physical examination showed no wound in the left leg. However, the pain is so severe that she cannot cooperate in sensory or motor exam. The leg's soft tissue is tense and firm on palpation. Passive motion of the toes intensifies the pain in the leg. Distal pulses are palpable, and capillary refill is delayed. X-ray shows fractures in the midshaft of both the tibia and fibula. What is the best management plan for her?
