Tailbone Injury Causes

Most coccyx injuries are caused by direct trauma to the tailbone area.

• A fall onto the tailbone in the seated position, usually against a hard surface, is the most common cause of coccyx injuries.
  
  
• A direct blow to the tailbone, such as those that occur during contact sports, can injure the coccyx.
  
  
• The coccyx can be injured or fractured during childbirth.
  
  
• Repetitive straining or friction against the coccyx (as happens in bicycling or rowing) can injure the coccyx.
  
  
• Sometimes, the cause of coccyx injuries is unknown.
  
  
• Less common causes of coccyx discomfort include bone spurs, compression of nerve roots or injuries to other parts of the spine, local infections, and tumors.
