We went to the hospital today and they said we could take Yusef home. He can finish his course of anti-biotics orally at home. We just have to watch him for any signs of infection. In two weeks he goes back to have the dressing checked, and in about 6 weeks they will remove the metal pins.
What a relief to have him home. Now we need to get him on to his studies - final exams are only a few weeks away.
