High-trauma fractures in older adults linked to osteoporosis, increased risk of another fracture

Contrary to a widely held assumption, high-trauma nonspine fractures in older women and men, such as from a car crash, are associated with low bone mineral density and an increased risk of a subsequent fracture, according to a study in the November 28 issue of JAMA.
