Do you get a cast when you fracture an elbow?

Yes: This type of fracture will need to be treated with a cast.

Depends: It really depends on the type of fracture, but yes, many elbow fractures will require initial casting. Very minor fractures may just be treated in a sling initially. The key to elbow fractures is to restore range of motion as soon as possible, typically starting at 2 - 3 weeks, so the cast is often switched to a hinged brace at that point.
