Fragility fractures are those that are the result of forces that would not fracture a normal bone. They can occur in the context of very low energy (i.e. minimal) trauma, or they may be no identifiable preceding trauma. There is overlap between fragility fractures and insufficiency fractures.
Fragility fractures occur in bones that have reduced compressive and/or torsional strength 1, and occur especially in the context of osteoporosis.
Common sites include 2:
- lumbosacral spine
- distal radius
- proximal humerus
