Osteosynthesis systems in fragility fracture

Atraumatic fractures, more commonly known as "fragility fractures", have as their basis the decreased bone strength due to osteoporosis. The major technical problem is the difficulty in obtaining secure fixation in osteoporotic bone, because the pull-out strength of implant is significantly reduced. The high rate of complications has encouraged extensive research into the development of implant which can improve the bone-implant interface by preventing high stress and distributing the forces transmitted to bone in a load-sharing, rather than load-bearing way.
