The pelvis is the sturdy ring of bones located at the base of the spine. Fractures of the pelvis are uncommon — they make up only about 3% of all fractures in adults. Most pelvic fractures are caused by some type of traumatic event.

Causes:

• High-energy trauma: A pelvic fracture may result from a high-energy force, such as a motorcycle collision, a crush accident, or a fall from significant height.

• Bone insufficiency: A pelvic fracture may also occur due to weak or insufficient bone. This is most common in older people whose bones have become weakened by osteoporosis. In people with osteoporosis, even a fall from a standing position or during a routine activity can result in a pelvic fracture. 

• Other causes: Less commonly, a fracture may occur when a piece of the ischium bone tears away from the site where the hamstring muscles attach to the bone. This type of fracture is called an avulsion fracture, and it is most common in young athletes who are still growing.

Management:

Based on the pattern and the severity of the fracture, your doctor may recommend surgical or non-surgical treatment. Patients with unstable pelvic fracture may require one or more surgical procedures. Your doctor may recommend non-surgical treatment for stable fractures in which the bones are non-displaced or minimally displaced. 

For patients that don’t require surgery, your doctor may recommend that you use crutches or a walker for up to 3 months or until your bones are fully healed in order to avoid bearing weight on your leg. If you have injuries above both legs, you may need to use a wheelchair for a period of time so that you can avoid bearing weight on either leg.
