Tibia Fractures

A 32-year-old male construction worker sustains a high-energy crush injury to his left leg when a steel beam falls on him. On arrival at the emergency department, he has severe swelling and ecchymosis over the anterior and lateral aspects of the leg. Plain radiographs reveal a comminuted fracture of the proximal and middle third of the tibia with a butterfly fragment. The fracture is open, with bone protruding through the skin. There is no distal neurovascular deficit. What is the Gustilo-Anderson classification of this fracture?

A 28-year-old male motorcyclist is brought to the emergency department after a high-speed collision. Examination reveals a grossly deformed left leg with the tibia angulated at approximately 45 degrees. The skin is intact, but there is severe swelling. Radiographs show a transverse fracture of the mid-shaft tibia with minimal comminution and an intact fibula. Neurovascular examination is normal. After initial resuscitation and pain control, what is the most appropriate initial management of this fracture?
