[Principles and new methods of flexible fixation of fractures of long bones]

The modern developments in orthopedic traumatology brought various modifications of modes and principles in operative fixation of fractures. Contrastingly to previous concept of rigid fixation as a priori necessary element for complete fracture union, a principle of flexible or elastic fixation took an equal place in contemporary professional doctrine. The results of these changes were technological innovations of fixation implants, with their mechanical characteristics as a base for their biological application that promoted essential advancements in fracture treatment and full functional recovery of injured patients. We review in this paper the modern principles and some new implant generations in flexible fracture fixation.
