How is a sacral fracture diagnosed?
- X-rays may be checked for broken bones or other problems.
- CT scan or MRI pictures may be taken of your sacrum. You may be given contrast liquid to help a fracture show up better in pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with any metal. Metal can cause serious injury. Tell your healthcare provider if you have any metal in or on your body.
How is a sacral fracture treated?
Treatment will depend upon the kind of fracture that you have. Mild sacral fractures that were caused by increased activity may be treated with rest alone. Medicine to decrease pain may be given so that you can return to your usual activities as soon as possible. After your fracture has healed, you may need an exercise program to increase your flexibility. Severe sacral fractures may require surgery to place your bones in their normal positions.
