Broken Tailbone - Information on Tailbone Problems Diagnosing and treating a broken tailbone. A broken tailbone can be a bit embarrassing and, sometimes, very painful. The most common cause of a broken tailbone is blunt force trauma, most often caused by falling in a sitting position onto a hard surface. Although a more conservative treatment is often the best approach when it comes to a broken or otherwise traumatized tailbone, it is not (as many believe) the only treatment.
