Overview

Causes

A coccyx fracture is caused by trauma from:

  • Falls
  • A blow to the tailbone
  • The childbirth process

It can also happen when straining or from friction, such as when rowing or biking.

Risk Factors

Things that may raise the risk of a coccyx fracture are:

  • Having a health problem that may result in falls, such as weak muscles
  • Having a health problem that may weaken bones, such as osteoporosis
  • Playing contact sports, such as hockey

SymptomsandDiagnosis

Symptoms

Symptoms may be:

  • Pain that is worse when sitting
  • Pain that is worse during a bowel movement

Diagnosis

The doctor will ask about symptoms and past health. The doctor will also ask how the injury happened. A physical exam will be done, focusing on your spine. A rectal exam may also be done. X-rays may or may not be needed.

Treatments

Treatment

The fracture will need time to heal on its own. This can take 8 to 12 weeks. The goal of treatment is to help the bones heal properly to prevent long term problems.

Support for all fractures can include:

  • Medicine to ease pain and swelling
  • A special cushion to sit on to ease pressure on the area.
  • Physical therapy

Surgery for this injury is rare. It may be done to remove the coccyx when all other options have been tried.

Prevention

Most fractures are due to accidents. Healthy bones and muscles may prevent injury. This may be done through diet and exercise.
