Hospitals do funny things. When I was in hospital in Camp Grant in WWII, Orthopedic ward was run by cardiologist, and Pneumonia ward was run by orthopedist. Fortunately they were allowed to cooperate.

Which reminds me of yarn I heard about situation in WWII, when an orthopedist in charge of neurology ward applied skeletal traction to case with fractured cervical vertebra by means of of a yoke attached to a Kirschner wire (a thing like a long knitting needle) from above one ear to the other. The med student who told me this at times was not a stickler for exactitude. He claimed his brother who was Army doctor told him about it.But it makes a good story.
