The sentence "He broke his collar bone in two places because he fell off the chair." is a complex sentence.

It has an independent clause ("He broke his collar bone in two places") and a dependent clause ("because he fell off the chair"). The dependent clause provides additional information and cannot stand alone as a complete sentence.
