Pronounced: cox-ix
A coccyx fracture is a broken tailbone. The coccyx is the lowest part of the backbone or spine. It is small, triangular in shape, and consists of four fused vertebra, or spine bones. Normally, it has a little bit of movement and curves gently from the end of the spine into the pelvis.
Causes of coccyx fracture include:
Factors that increase your chance of a coccyx fracture include:
Symptoms may include:
The doctor will ask about your symptoms and how the injury occurred. A physical exam will be done. The exam may include a rectal exam. During a rectal exam, the doctor places a lubricated, gloved finger into the rectum and feels for any abnormalities. If the coccyx is fractured, your doctor may feel abnormal movement of the coccyx, and you will experience pain. X-rays may or may not be required.
The goal is to manage pain until the bone can heal. Doctors usually do not try to correct a bad alignment. Muscles in the area are powerful and can pull the coccyx back out of position. The location of the coccyx and the number of muscles attached to it make immobilization very difficult.
The area may remain painful for a long period of time, even after the fracture has healed. You may be advised to stay in bed for a day or two, or move only as comfort allows. Steroid injections or surgery may be considered if severe pain persists. Surgery for a painful coccyx fracture is very rare and not very successful. Usually pain gradually disappears.
You may be given medication to ease the pain. To reduce discomfort during bowel movements:
Sitting can be very uncomfortable after a coccyx fracture. Suggestions to make sitting less painful include:
If pain continues and causes disability, a coccygectomy might be recommended. During this procedure, the doctor removes the coccyx. It is not a common procedure and the success rate is not what one would hope for.
If you are diagnosed with a coccyx fracture, follow your doctor's instructions .
