Fractures of the pelvis are a consequence of undue stress onto a weakened bone. Osteoporosis is the most common cause of fractures of the pelvis. Major or minor trauma is another cause; however, spontaneous sacral insufficiency fractures are also common. The incidence of sacral insufficiency fractures comprises of approximately 1% to 2% of pathologic fractures involving the spine and pelvis. However, these fractures are often misdiagnosed and unrecognized. Risks of sacral insufficiency fractures are very similar to that of vertebral compression fractures.
