Engineering implants for fractured bones-metals to tissue constructs

Author(s): Ranjna C Dutta*, Aroop K Dutta and Bikramjit Basu

Bones are essential component of spatial framework that provides visceral protection and define the shape of an organism. Similar to steel framework of a building, bone scaffold is indispensable for imparting a unique shape and imposing the body in one piece. Keeping this framework in requisite order and form post accidental fractures and breakages is a challenge. Present article discusses in brief the successive evolution in managing bone injuries and defects. It evaluates the rationale behind a shift in attention from metals to ceramics and polymer-ceramic hybrid composites as the implant material. Contemporary development of tissue engineering and bone-regeneration techniques and their need under specific context and situation is also discussed.
