A broken horn is a common injury suffered by those with broken fibula and/or a broken horn extractor.
In the United States, it is estimated that about 1.5 million people a year suffer from broken horn.
The injury is caused by the fibula snapping off and breaking off the inner part of the horn.
Breaking off the horn is an extremely painful process and many people have difficulty getting up.
It is also extremely dangerous, with some injured people unable to walk and some even die.
