Exams and Tests

The cause of a coccyx injury is largely determined based on a medical history and a physical examination. Occasionally, x-rays or other imaging studies may be performed.

• The entire vertebral column (spine) may be examined. A neurologic examination may be performed. A rectal examination may also be performed. For this exam, the physician inserts a finger into your rectum to feel the area of the coccyx and determines if there is a dislocation or a fracture that can be felt and if direct pressure against the coccyx reproduces your pain.
  
  
• X-rays may be taken to determine whether there is a fracture or dislocation. However, x-rays occasionally may not reveal these injuries. Some physicians recommend x-rays in both the standing and seated positions to better determine the presence of a fracture or dislocation. Rarely, at the discretion of your physician, a MRI (magnetic resonance imaging) may be ordered at a later time if x-rays do not reveal the cause of continuing coccyx discomfort.
