Osteoporotic fractures of the proximal humerus, pelvis, and ankle: epidemiology and diagnosis.

Although fractures involving the wrist, spine, and proximal femur are known to be strongly associated with osteoporosis, the underlying bone insufficiency often receives insufficient diagnostic and therapeutic attention. Osteoporosis also increases the risk of fractures at other sites. Low-energy fractures in patients older than 50 years should lead to investigations for osteoporosis, the only exceptions being fractures of the skull, cervical spine, fingers, and toes. The incidence rates of fractures of the proximal humerus, pelvis, and ankle are climbing relentlessly. Whereas fractures of the proximal humerus and pelvis are undoubtedly related to osteoporosis, the link is less well established for fractures of the ankle. Mortality and morbidity rates associated with pelvic fractures are similar to those seen with fractures of the proximal femur, in keeping with the fact that both fractures occur in elderly individuals.
