                  Abstract: Despite the high  innate regenerative capacity of bone, large osseous defects fail to heal and remain  a clinical challenge. Healing such defects requires the formation of large  amounts of bone in an environment often rendered hostile to osteogenesis by  damage to the surrounding soft tissues and vasculature. In recent years, there  have been intensive research efforts directed towards tissue engineering and  regenerative approaches designed to overcome this multifaceted challenge. In  this paper, we describe and critically evaluate the state-of-the-art approaches  to address the various components of this intricate problem. The discussion  includes (i) the properties of synthetic and natural scaffolds, their use in  conjunction with cell and growth factor delivery, (ii) their vascularisation,  (iii) the potential of gene therapies and (iv) the role of the mechanical  environment. In particular, we present a critical analysis of where the field  stands, and how it can move forward in a coordinated fashion.  |
